@EdoardoCinelli Do you have the linker behavior set to "SDK Only" or "Link All" for the Release|iPhone configuration?

I also followed the link as well and I am still getting that message. below is also the cs.proj for my app if that will help out any at all. The linker is set to be link framework sdk's only and I added "--optimize=experimental-xforms-product-type" to the mtouch argumants.

@mharrisonbit I think the same as @hartez mentioned applies to you.

In the <PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|iPhone' "> bit please add this tag: <MtouchLink>Full</MtouchLink>. You can also do that from the UI by going into the iOS project properties, go to the iOS Build blade and make sure that Linker behavior is set to either Link All or SDK Only, see below.

Of course make sure you do that for the right build configuration, use the comboboxes in the top of the screen for that

I've tryed both but i'm still receving the mail from apple.
How can i fix it?

Can one of this contain a reference to uiwebview?

 <PackageReference Include="Newtonsoft.Json">
      <Version>12.0.3</Version>
    </PackageReference>
    <PackageReference Include="Xamarin.Firebase.iOS.CloudMessaging">
      <Version>3.1.2</Version>
    </PackageReference>
    <PackageReference Include="Xamarin.Forms" Version="4.5.0.356" />
    <PackageReference Include="Xamarin.Essentials" Version="1.5.0" />
    <PackageReference Include="Xamarin.Forms.Visual.Material">
      <Version>4.5.0.356</Version>
    </PackageReference>
    <PackageReference Include="Xamarin.IQKeyboardManager">
      <Version>1.4.1</Version>
    </PackageReference>

@EdoardoCinelli it looks like the Firebase one is referencing UIWebView and they are working on it: https://github.com/xamarin/GoogleApisForiOSComponents/issues/369

@mharrisonbit just to update the others; we have chatted offline a bit, you seem to have all the right versions and settings, but still doesn't seem to work. You already sent me a list of NuGets as well, could you please add that here? So we can see if there is anything in there that might cause trouble.

Hi!

I have the same issue. We chatted a bit by mail with @jfversluis, and now I will continue this here.

I'm using AppCenter to build and publish on testflight. I didn't write it before. I removed all the firebase reference from code and NuGet and i'm still receving the mail. Is AppCenter the probolem?

@EdoardoCinelli could you check your build configuration on App Center?

Make sure you have selected the Xamarin.iOS 13.10 version to build your app

This is my setup

@jfversluis here are the nugets that I am using in the iOS project, I am hoping this will help figure something out. Again thanks everyone for the help. Also this is all being archived on my local and then pushed to the play stores.

Alright, it looks like a number of you are using the Material visual which depends on MaterialComponents. The latest stable version is 72.2.0.1 but I came across this issue https://github.com/xamarin/XamarinComponents/issues/745 which states that the reference to UIWebView is only removed in 92.0.0-rc1.

Check if you are actually using Material in your project. If not, try to remove the reference _or_ add the 92.0.0-rc1 (or rc2) to your project manually and see if that fixes it.

For the people who are (also) building on Azure DevOps, please beware that you might not be building against Xamarin.iOS 13.10. Check your logs to see if there is any output that states that the experimental-xforms-product-type flag is not a valid one. If you see that output, you are building against an older version of Xamarin.iOS.

For the ones on Azure DevOps, follow the link underneath and set the Mono version to 6_6_1, that builds against Xamarin.iOS 13.10

https://docs.microsoft.com/en-us/azure/devops/pipelines/agents/hosted?view=azure-devops#how-can-i-manually-select-versions-of-tools-on-the-hosted-macos-agent

Also tested without Appcenter and without firebase, webview, xamarin materials and xamarin essential and i'm still receving the mail. Can someone tell me what is going on? How can i check if i have some reference?

I tried removing Xamarin.Forms.Visual.Material and still received the mail too.

@Flaviocrtt After removing the nuget, please make sure to do the "bin/obj dance". Remove the bin and obj folder from your project and make sure to do a full rebuild so nothing cached gets stuck in there.

Also, how are you building your app? Azure DevOps, App Center, manually? Are you sure you have all the right settings in place?

I just created a build and I didn't get that message, I didn't make any changes to the nuget packages that are referenced just some design changes that were asked for.

@mharrisonbit what do you mean exactly by "design changes"?

No major changes just some margin in a couple views. I didn't add or remove any elements(labels, buttons, etc) to any view.

OK, that is... strange. Maybe suddenly for this build some bits fell into place and you got a proper binary? Anyway, glad to see it's resolved! :)

I know how my luck is and this was just a one time thing. lol I hope that everything just fell into place and I am good to go from here on out. I thank everyone for all the help.

@jfversluis It worked, I removed Xamarin.Forms.Visual.Material, cleaned the solution, removed the bin and obj folders, and even restarted visual studio and macMini by guarantee.
I build Manually using Visual Studio Preview for windows, connected on mac mini.
in fact i need the visual material, i'll install back to my app again and i know that if apple starts refusing my app i can send it without the material.
Do you have any forecast for updating the visual material with the necessary correction?
Thanks!

Great @Flaviocrtt! Thanks for letting us know!

I think the update for the material things are already in progress. If you want to use them right now, just install it again but update the MaterialComponents NuGet on your iOS project to the latest pre-release. Again clean all the bin and obj stuff, but that should work and let’s you use material :)

@EdoardoCinelli seems like we got most of the people here to get it working, did you also?

Ok, i fixed it. This was my procedure.

Build on visual studio in win10 with a mac-mini online connected via network. The steps was this:

• "bin/obj dance"
• Uninstall Xamarin.Visual.Material.Design from the project
• "bin/obj dance"
• Install Xamarin.iOS.MaterialComponents instable version 92.0.0-rc2
• Install Xamarin.Visual.Material.Design 4.5.0.356

The only problem was that component. Firebase cloud messaging wasn't the problem. Thx for the help.

Hi @jfversluis I also have this issue, i don't use Material component.
This is my build configuration - I use AppCenter to build Ipa file.

Please give advice.

@vunhutien try to upgrade the plugins that have to do with ads. That seems a likely package to reference a webview

Thank @jfversluis, I upgraded all plugin to latest version, still got issue, any idea?

@vunhutien looks like this issue might be your cause: https://github.com/xamarin/GoogleApisForiOSComponents/issues/380

@vunhutien looks like this issue might be your cause: xamarin/GoogleApisForiOSComponents#380

Thanks so much.

@rdev24608 it looks like you’re not using the 4.5 stable package which is a requirement

@rdev24608

Try this
https://github.com/xamarin/Xamarin.Forms/issues/9823#issuecomment-594758733

If it still doesn't work what's the exception?

exception?

Try checking which package contains reference to UIWebView by unzipping your *.ipa file, cd to the unzipped directory, and do grep -lr "UIWebView" . from your terminal.

Hi @abrari , my package showed: /Frameworks/PersonalizedAdConsent.framework/PersonalizedAdConsent
I guess it from Google Ad lib right?

Hi @jfversluis I also have this issue, i have updated to Xamarin.Forms 4.5.0.495 and Xamarin.iOS 13.14.1.39. I also did the exact same configurations as mentioned in the blog, but i still get the warning message.

@rambo1223 seeing that you are using Material, this might be the case: https://github.com/xamarin/Xamarin.Forms/issues/9823#issuecomment-594599608

@jfversluis thanks for your quick reply, i actually use the latest version of Xamarin.Forms.Visual.Material as the version of Xamarin.Forms, should i install Xamarin.iOS.MaterialComponents also?

For the time being; yes. We have a PR open that should update the reference, but for now you should add the latest Xamarin.iOS.MaterialComponents package manually and that should fix it.

@jfversluis
Good day! having the same warning email in my app, do not use any MaterialComponents I'm my packages, also installed the latest Xamarin.Forms stable version all needed updates and setups that are listed in this thread.
All latest stable version of SDKs are also on the place

also did applied unzip of my ipa and performed grep and got
SomeMobileApp.iOS.app/Xamarin.Forms.Platform.iOS.dll
SomeMobileApp.iOS.app/SomeMobileApp.iOS
SomeMobileApp.iOS.app/Xamarin.iOS.dll

also installed the latest Xamarin.Forms stable version all needed updates and setups that are listed in this thread.

Which versions would that be? :)
I don't see any NuGets that seem to cause this, so it must be something in your build configuration. Are you building through Azure DevOps or App Center by any chance? Did you set the right configuration for the relevant build configuration? It would be helpful to see some of that.

Also make sure you read this follow-up documentation by the Xamarin.iOS team which might help: https://docs.microsoft.com/en-us/xamarin/ios/release-notes/13/13.16#help-with-uiwebview-deprecation

@jfversluis Good day!

Thanks for such fast replies and help.

I did read the article you shared , have not applied yet --warn-on-type-ref=UIKit.UIWebView
but have tried to apply --optimization=force-rejected-types-removal and got error, as in latest updates there is no such argument.
And yes, for sure we do not use any of UIWebView in our renderers, but we use WKWebView.

We are building purely on windows PC connected to mac with MSBuild utils, we do not use any other solutions.

for the configuration the needed flag applied to all configurations, so will list only related to release type,
this will be listing of configurations:

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|iPhone' "> <DebugType>none</DebugType> <Optimize>true</Optimize> <OutputPath>bin\iPhone\Release</OutputPath> <ErrorReport>prompt</ErrorReport> <WarningLevel>4</WarningLevel> <MtouchArch>ARM64</MtouchArch> <ConsolePause>false</ConsolePause> <CodesignKey>iPhone Developer</CodesignKey> <MtouchLink>SdkOnly</MtouchLink> <MtouchSdkVersion>13.4</MtouchSdkVersion> <CodesignEntitlements>Entitlements.plist</CodesignEntitlements> <MtouchExtraArgs>--optimize=experemental-xforms-product-type</MtouchExtraArgs> </PropertyGroup> <PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Ad-Hoc|iPhone' "> <DebugType>none</DebugType> <Optimize>True</Optimize> <OutputPath>bin\iPhone\Ad-Hoc</OutputPath> <ErrorReport>prompt</ErrorReport> <WarningLevel>4</WarningLevel> <ConsolePause>False</ConsolePause> <MtouchArch>ARM64</MtouchArch> <MtouchLink>SdkOnly</MtouchLink> <MtouchSdkVersion>13.4</MtouchSdkVersion> <BuildIpa>True</BuildIpa> <CodesignProvision> </CodesignProvision> <CodesignKey>iPhone Developer</CodesignKey> <CodesignEntitlements> </CodesignEntitlements> <CodesignExtraArgs /> <CodesignResourceRules /> <MtouchExtraArgs>--optimize=experemental-xforms-product-type</MtouchExtraArgs> </PropertyGroup>

I also believe that this is not related to libraries, as grep show occurrence of UIWebView in SomeMobileApp.iOS.app/Xamarin.Forms.Platform.iOS.dll
SomeMobileApp.iOS.app/SomeMobileApp.iOS
SomeMobileApp.iOS.app/Xamarin.iOS.dll

but have tried to apply --optimization=force-rejected-types-removal and got error, as in latest updates there is no such argument.

I'm not sure what you mean by this. I interpret this as; you tried to use this argument, but it didn't work. What error did you get when using this?

It's strange. Everything seems to be in order, but we must be missing something.

Now that I have a close look at you csproj I see the flag you're using has a typo <MtouchExtraArgs>--optimize=experemental-xforms-product-type</MtouchExtraArgs> should be <MtouchExtraArgs>--optimize=experimental-xforms-product-type</MtouchExtraArgs> notice experemental is spelled wrong

I had this problem too but it disappeared.. I think everyhting was perfectly in order though. I was not using Material.
Xamarin.Forms 4.5.0.530
Xamarin.IOS 13.16.0.11

Don't really know what finally fixed it because --warn-on-type-ref=UIKit.UIWebView kept complaining there were still references in Xamarin.Forms.Platform.IOS and i tried so much to get rid of it, but you can try this:

• delete the bin & obj folders.
• delete the cache on the Mac in ~/Library/Caches/Xamarin/mtbs

--warn-on-type-ref=UIKit.UIWebView still says there are references but the App Store is not complaining anymore. I hope it's not a fluke though..

Hey there,
still got the same problem. I tried all the things, even the "--warn-on-type-ref=UIKit.UIWebView" and it references to:
One or more reference(s) to type 'UIKit.UIWebView' still exists inside 'Xamarin.Forms.Platform.iOS, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null' after linking (Even before linking)

I'm using Xamarin.Forms.iOS 4.5.0.617 (latest) and didn't use any reference in my iOS code.
What can I do to find the problem?

Edit:
AppConnect still references the problem, I'm building my app using appcenter with Xamarin.iOS 13.14 (Mono 6.8) and XCode 11.4.
The reference flag --optimize=experimental-xforms-product-type was set, but nothing changed...

Could you please find my email address on my GitHub profile and reach out there? There hasn't been a case we couldn't solve, so let's fix it for you!

Hi @jfversluis ,
I got the same problem as of @R41z0r

First, I followed your article - https://devblogs.microsoft.com/xamarin/uiwebview-deprecation-xamarin-forms/

Then, I manually figured out the dlls that could refrence the UIWebView.

• Xamarin.auth

• MonoTouch.Dialog

After removing these from my project, I resubmitted the app to store and still get the same warning from apple.
Then I came to know about --warn-on-type-ref=UIKit.UIWebView.

After using --warn-on-type-ref=UIKit.UIWebView in my project following error occurred.
One or more reference(s) to type 'UIKit.UIWebView' still exists inside 'Xamarin.Forms.Platform.iOS, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null' after linking (Even before linking)

Xamarin.Forms version - 4.6.0.726
Xamarin.iOS version - 13.16.0.13
Linker Behavior - SDK Only
mtouch arguments - --optimize=experimental-xforms-product-type

I checked the Xamarin.Forms.Platform.iOS using object browser. I suspect it still contain WebViewRenderer. Refer the attached screen shot

Am I doing something wrong here?

I'm in the same boat. I can't get my azure pipeline to submit to apple without the error rejection.
See my stackoverflow question for more detail https://stackoverflow.com/questions/61567850/still-getting-itms-90809-deprecated-api-usage-after-using-optimize-force-reje?noredirect=1#comment108910675_61567850

What is the correct mtouch args to enter? Is it
--optimize=experimental-xforms-product-type
or
--optimize=force-rejected-types-removal

or both?

Ok, I'm still stuck. I've done some testing with my project and this is what I've found out.
If I run it with only --warn-on-type-ref=UIKit.UIWebView -warnaserror:1503
my build fails with the MT1503 which is the UIWebView is still present after linking.
If I run it with the warning plus --optimize=experimental-xforms-product-type
I get the same result, error on MT1503, so it seems that this does nothing.
If I run it with --optimize=force-rejected-types-removal my build succeeds with no message about anything UIWebView after linking.

In my real pipeline I was running --optimize=force-rejected-types-removal, but Apple still rejects it. So, I don't get what the problem is. I don't use UIWebView anywhere in my project.

>

Just to mention, my problem was, I forgot to set the argument on all
instances (debug/release, iPhone/iPhone simulator).

Check that maybe it'll help you.

@R41z0r Thanks. Yeah it is set, I can see it in my azure build logs. This is such an annoying problem because my build pipeline is useless at this point and I have testers/stakeholders who get weekly builds pushed out via testflight.

Finally managed to clear the apple verification. In my case there was a library (Branch-Xamarin-Linking-SDK) which was responsible for rejection of app. I just updated it and app passes the apple's exam. I was using an older version of this library. Big task was to identify the library among many others in our project.
After spending few days on this I can say, --warn-on-type-ref=UIKit.UIWebView doesn't give true results. If you are left with one warning in build logs try submitting it to testflight.
Best approach to proceed is to update all libraries to the latest version and adjust you source code accordingly. If still that doesn't work, try removing the most doubtful libraries one by one and commenting out the code of that library in your project and then submitting the builds to testflight. I know it's bit time taking but worth spending time on your project to pass apple rejection.

I forgot to come back and post my method for getting my app to get through the Apple verification. I had so many posts out there I missed circling back to this one.

What ended up working for me was building locally and packaging the ipa file. On my mac I then changed the ipa extension to zip and unzipped it. I used terminal to go to the YOURAPPNAME.app "folder" and used grep -r UIWebView . to search for references. Don't forget the . so it searches the current directory. I missed that at first and got some message that grep was listening on stdin.

For me that resulted in a line like this:
Binary file ./Frameworks/PersonalizedAdConsent.framework/PersonalizedAdConsent matches

Now, the important thing to note is the linker never warned about this, so I was completely unaware of it. In my case it was part of Firebase/Admob. I was only one release behind and updating to the latest fixed my problem.

I still am using --optimize=force-rejected-types-removal --warn-on-type-ref=UIKit.UIWebView -warnaserror:1503 as my mtouch args. But builds now get through.

I hope this helps someone get to the root cause faster.

I updated Visual Studio and Xcode to the latest but --optimize=experimental-xforms-product-type still didn't work for me.
Fortunately --optimize=experimental-xforms-product-type --optimize=+force-rejected-types-removal did.

but have tried to apply --optimization=force-rejected-types-removal and got error, as in latest updates there is no such argument.

I'm not sure what you mean by this. I interpret this as; you tried to use this argument, but it didn't work. What error did you get when using this?

It's strange. Everything seems to be in order, but we must be missing something.

--optimization=force-rejected-types-removal results in mono error Unknown command line argument

Hi,
Shouldn't the argument --optimization be --optimize

@taublast @Bradtus that is correct. There is one documentation page where optimization was written in error. It should be optimize

Here the same problem. Is't not possible that today we are blocked for this when Apple advise of deprecation from some months.

@biapar

• Update Xcode, update Visual Studio.
• Make sure you're submitting a build from RELEASE not DEBUG
• Follow all instructions in https://docs.microsoft.com/en-us/xamarin/xamarin-forms/user-interface/webview?tabs=windows#uiwebview-deprecation-and-app-store-rejection-itms-90809
• Follow all instructions in https://docs.microsoft.com/en-us/xamarin/ios/user-interface/controls/webview#uiwebview-deprecation

Hi @biapar you’re totally right. And you should not be blocked by this, because the solution we have in place has also been here for a few months now for you. And it has been proven that it works each time.

Let me know what doesn’t work for you and we can figure it out

@biapar

• Update Xcode, update Visual Studio.
• Make sure you're submitting a build from RELEASE not DEBUG
• Follow all instructions in https://docs.microsoft.com/en-us/xamarin/xamarin-forms/user-interface/webview?tabs=windows#uiwebview-deprecation-and-app-store-rejection-itms-90809
• Follow all instructions in https://docs.microsoft.com/en-us/xamarin/ios/user-interface/controls/webview#uiwebview-deprecation

I already made everything ( in RELEASE mode ). I'll try again step by step.

Did you also actually submit a build to the App Store? I think there are some cases where the warnings in the output might give false positives. Also, are you archiving your app through Visual Studio for Mac or are you doing it through App Center or Azure DevOps by any chance?

@biapar your other option is to comb through your app output to locate what is still referencing UIWebView

https://github.com/xamarin/Xamarin.Forms/issues/9823#issuecomment-624655801
Or you can drop all your dlls into vsmac and inspect/search type types that way

Hi,
Shouldn't the argument --optimization be --optimize

Wow nice one!
@jfversluis here (https://docs.microsoft.com/en-us/xamarin/ios/release-notes/13/13.16) they just give you the wrong line:

A forceful solution is to add --optimization=force-rejected-types-removal to your project's Additional mtouch arguments. This will remove traces of UIWebView from the application. However any code that refers to the type will not work properly (expect exceptions or crashes). This should be used only if you're sure that the code is not reachable at runtime (even if it was reachable through static analysis).

Anyway i managed to pass it to AppStore with the following:

1. enable incremental builds OFF (important)
2. monotuch additional stuff: --optimize=experimental-xforms-product-type --optimize=+force-rejected-types-removal --warn-on-type-ref=UIKit.UIWebView -warnaserror:1503

here (https://docs.microsoft.com/en-us/xamarin/ios/release-notes/13/13.16) they just give you the wrong line:

I've opened a PR on that doc to fix that. There is a couple of more people that approached me with it now working, but unfortunately it's not merged yet.

Glad to hear you fixed it though!

@jfversluis I have same problem with this UIWebView Deprecation issue.
I have tried each solution provided by you and other guys.

1. I changed the link behavior to Link All.

2. I added the MTouch Link parameters --optimize=experimental-xforms-product-type --optimize=force-rejected-types-removal --warn-on-type-ref=UIKit.UIWebView

3. Upgraded nuget package for xamarin.Forms to latest version(4.6.0.726)

4. I'm using the latest version of Visual Studio For Mac community :
   Visual Studio Community 2019 for Mac
   Version 8.5.5 (build 7)

5. My Xamarin.iOS is 13.16.0.13:
   Xamarin.iOS
   Version: 13.16.0.13 (Visual Studio Community)
   Hash: b75deaf82
   Branch: d16-5-xcode11.4
   Build date: 2020-04-01 21:33:19-0400

But I still get the UIWebView Deprecation issue message from Apple when I pushed a new build to testflight.
I still get this message when I created a build.
MTOUCH : warning MT1502: One or more reference(s) to type 'UIKit.UIWebView' already exists inside 'Xamarin.Forms.Platform.iOS, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null' before linking

Could you tell me what's I am missing? What should I to do to fix this issue.

My project have a reference to other library project, which is a Visual Studio project, it generated a library be used in this project.

Hey @W0126 could you please try the grep suggestion from this comment and let me know what the outcome is from that?

Also, make sure that you clear the bin/obj folders to make sure there is no caching involved.

Double-check that you have configured the flag and settings for the right build configuration and that that is also the build configuration that you are using on any CI/CD system you might have in place.

@jfversluis

I did a grep command for my App.
It output binary file ./Payload/uPyxis.app/uPyxis matches

the uPyxis is my App.

But I do not use UIWebView in my code. I have no idea where the UIWebView come from.

I sure that I cleaned all bin/obj folders and all configuration have correct configured with the flag and settings.

@jfversluis
I finally find out it is caused an old third-library, HockeySDK, which is very old and not active now.
So I removed this package.
It should allow my app go through testflight without any warnings now.

Thanks.

That is great news @W0126! Let me know how it goes!

Hi,

I am developing apps using XF for last 5 years.
I am also facing same issue and very disappointed. Sometimes I decided to switch to another platform because of lack of support and targeted help from the Xamarin.

Then I walked through this link https://devblogs.microsoft.com/xamarin/uiwebview-deprecation-xamarin-forms/
I followed all the instructions and successfully uploads build on TestFlight for testing.
BUTTTTTTTTT

By changing LinkAll I am facing serious issues with Signalr I am not able to use the signalr functionality If I change the linking option to LINK ALL.

ERROR

A suitable constructor for type 'Microsoft.AspNetCore.Http.Connections.Client.HttpConnectionFactory' could not be located. Ensure the type is concrete and services are registered for all parameters of a public constructor.

I tried to use skip option but no luck.

--linkskip=Microsoft.AspNetCore

I am disappointed that Xamarin is not capable to help the developers.

If someone has any solution so please help me out .

@LumiProj did you by any chance try to set the Linker Behavior to SDK Only?

I solved to update again each packages ( they was updates -1 version ) and made again the steps.
This is my Apple Config:

Hi,

I am also facing issues and have tried the suggested fixes mentioned above. I tried Link Sdk and Link All with these tags --optimize=experimental-xforms-product-type --optimize=+force-rejected-types-removal --warn-on-type-ref=UIKit.UIWebView -warnaserror:1503 on all my builds (debug/release). I have also updated all my packages, these are the NuGet Packages I use:
(IOS)

(Project)

When I try grep -r "UIWebView" . as suggested above, I get Binary file ./MyApp.iOS.app/Xamarin.Forms.Platform.iOS.dll matches Binary file ./MyApp.iOS.app/Xamarin.iOS.dll matches Binary file ./MyApp.iOS.app/MyApp.iOS matches

I don't explicitly use any UIWebView in my project (Search in VS doesn't reveal anything)

This is my configuration

(It doesn't work with the Link Sdk or Link All)

I've been looking through different examples and various forums over the past several days and none of them are able to remove the mentions in the binary files when I grep -r "UIWebView" . and thus are all rejected by the app store. Any suggestions or advice would be greatly appreciated!

Hi,

Finally I am in good shape.
using --optimize=experimental-xforms-product-type
with LinkSdkAssemblies.

Awesome @LumiProj !

@JJwilkin I have an email from you I see. We'll figure it out there!

I forgot to come back and post my method for getting my app to get through the Apple verification. I had so many posts out there I missed circling back to this one.

What ended up working for me was building locally and packaging the ipa file. On my mac I then changed the ipa extension to zip and unzipped it. I used terminal to go to the YOURAPPNAME.app "folder" and used grep -r UIWebView . to search for references. Don't forget the . so it searches the current directory. I missed that at first and got some message that grep was listening on stdin.

For me that resulted in a line like this:
Binary file ./Frameworks/PersonalizedAdConsent.framework/PersonalizedAdConsent matches

Now, the important thing to note is the linker never warned about this, so I was completely unaware of it. In my case it was part of Firebase/Admob. I was only one release behind and updating to the latest fixed my problem.

I still am using --optimize=force-rejected-types-removal --warn-on-type-ref=UIKit.UIWebView -warnaserror:1503 as my mtouch args. But builds now get through.

I hope this helps someone get to the root cause faster.

Thank you so much jmichas.
You save many of my worked days. I did everything I could using every guidelines and suggestions given and none can really get rip of UIWebView reference in Xamarin.Forms.iOS.Platform dll. I was almost there but something missing and I can escape from App Store rejection. And finally I found the final missing piece from you and it worked now. I can start testing stage now.

Have the same problem.
Followed all the new rules with latest everything.
Did the surgery eephyu suggested to unpack the ipa
grep still finding a reference to UIWebView in the app binary only.
¯_(ツ)_/¯

And the Answer is CALABASH! and the Xamarin TestCloudAgent nuget package.
Remove that package and any Calabash.Start() reference and you'll pass the App Store.

@pmace great you found the solution. In any case, the Calabash package should always be removed from the build going to the App Store since it uses private APIs that Apple won't allow anyway :)

For anyone finding this: give Xamarin.Forms 5 (pre-release atm) a shot, that has the UIWebViewRenderer removed and should get you out of this trouble without any build flags or other hassles

I have this same problem :( , @JJwilkin did you resolve it?

@jmatusburgos please post the details of your project of send me an email directly

@jmatusburgos Follow this should work.
https://github.com/xamarin/Xamarin.Forms/issues/9823#issuecomment-630945296

Hi @LumiProj Im have that arguments.

@jfversluis Im use Xamarin.forms 4.8.0.1364. I'm had unistall many libraries like googleAnalytics and Google.SigIn that gave me references to UIWebView and Im upgraded anothers until the command grep dont show me reference on some library, but now when I use grep -r "UIWebView" . I get Binary file ./MyApp.iOS.app/Xamarin.Forms.Platform.iOS.dll... don't show me about some explicit reference.

I'm use VS2019 on microsoft machine and mac with XCode 12.

this is my configuration:
I tested with Link All and LinkSdkAssemblies

@jmatusburgos could you maybe find my email on my GitHub page and reach out there so we can figure this out? :)

@jfversluis thanks for you response, I want comment you that with help of my co workers we found 3 libraries that caused the issue :

Refractored.XamForms.PullToRefresh 2.4.1
Paypal.Forms 2.18.6
Xamarin.PayPal.iOS 2.18.0

All these libraries are obsolete . We have removed and finally works.
the interesting of this its that with the command grep didn't showed the match of this libraries.

So sometimes can be a jigsaw found the guilty libraries. again, thanks @jfversluis for you'r availability :)

Yeah I think because they are including native libraries that they created a wrapper around that is not picked up by that grep command. Sorry for the trouble, glad you figured it out!
