Ionic-framework: ios **BUILD FAILED ** duplicate symbols for architecture x86_64

Hello! Thank you for opening an issue with us!

I cannot duplicate your error, which makes total sense because as you say, it generally works and then mysteriously stops. So... let's start with some versions of things:

I am using Xcode 9, what version are you using?
I am using cordova-ios version 4.4.0, which looks the same as what you are using...

Hmmmm... I am going to try a couple of things

Hey @kensodemann , I am currently on Xcode Version 8.2.1

Thank you!

Try remove plugin console and try again, I had the same issues. But I have Cordova ios 4.5

The problem is CDVLogger that is already in cordova cli 7

Duplicated it and fixed it, though I am not entirely sure this is your issue, but worth a shot.

First, I remove my node_modules and platform/ios directories and did an npm i and ionic build, which ended up installing cordova-ios version 4.5.0, which caused the exact same issue you have.

My guess (and it is only a guess) is that you somehow have cordova-ios 4.5.0 even though ionic info is reporting 4.4.0 (weird, but I have no better explanation at this point).

So I did this:

1. In package.json, change "cordova-ios": "^4.4.0" to "cordova-ios": "4.4.0" (no '^')
2. In config.xml, change <engine name="ios" spec="^4.4.0" /> to <engine name="ios" spec="4.4.0" />
3. rm -rf node_modules/ platforms/ios/
4. npm i
5. ionic cordova build ios
6. * BUILD SUCCEEDED *

So at least for me, the key to the fix was pinning the cordova-ios version to 4.4.0 rather than using ^4.4.0, which will take upgrades to the minor version.

Of course, this means when it is time to upgrade cordova-ios, you will have to do it manually, but you probably want that control anyhow.

Anyhow, give that a try and let me know if that works for you.

@kensodemann Exactly the issue!

@kensodemann Hooray, I can now build, Thank you!!

Here's the thing, before doing ioinc build I went into my package.json file and here's what I found "cordova-ios": "^4.4.0", and not ^4.5.0.

Anyway, so I followed your instructions, ran rm -rf node_modules/ platform/ios then npm i and npm build.

That last command then changed my "cordova-ios": "^4.4.0", to "cordova-ios": "^4.5.0",.
In order to follow your instructions as close as possible, I changed it to your suggestion "cordova-ios": "4.4.0", (same thing for config.xml).

Uninstalled my node_modules & platform/ios once again and ran npm i then ionic cordova build ios and it worked.

Surprisingly enough, after doing so, I still find myself with "cordova-ios": "^4.4.0", in my package.json and <engine name="ios" spec="^4.4.0" /> in my config.xml

Surprisingly enough, after doing so, I still found myself with "cordova-ios": "^4.4.0", in my package.json and in my config.xml

My guess is that Cordova does that. Personally not a fan of tools mucking with my setup... :(

I am going to close this then. Glad it is working for you now.

@nuno is correct, the console plugin is the root cause, that has been included in cordova 7, so simply remove the plugin fixes the problem.

@surajitdeveloper -

Are you sure you are not installing the console plugin?
Did you remove everything and re-install from scratch?

If your repo is online, provide a link and I can take a quick look. In general, though, this is not an Ionic Framework issue but an issue with the use of incompatible plugins.

@kensodemann is right, it is all due to plugins being either old or incompatible.

For me, it turned out to be the cordova-plugin-inappbrowser. In my config.xml, there was still a reference to a git repo that didn't exist anymore. I first didn't take notice in the build process, but all of a sudden, I noticed that the build was complaining about not finding the repo for the plugin. The solution was quite simple: put the line in the config.xml in comment, and reinstall the plugin. And iOS was building again :)

So, if it may help, check you build log after you run ionic cordova build ios - it may contain errors about plugins. And check all of your plugins: simply reinstalling them might not help, you may have to update versions too.

Solution from @nuno works for me, just run:
cordova plugin rm cordova-plugin-console
cordova platform rm ios
cordova platform add ios
cordova build ios
I'm using cordova-ios version 4.5.4.

Hi all,

I had same problem and I have tried to execute solution posted by @didinj and not works because after this I get an error for scripts when execute rm platform and then build ios, I add again app-scripts but the problem was this : npm install @ionic / app-scripts@latest --save-dev because install 3.1.7 version of scripts and this generate the same main error then I execute and again app-scripts but with a less version for app-scripts and now works fine with 3.0.0 : npm install @ionic / [email protected] --save-dev

I'm using too cordova-ios version 4.5.4 and the all latest versions of all in macOS High Sierra 10.13.2 with Xcode 9.2

cli packages: (/usr/local/lib/node_modules)

@ionic/cli-utils  : 1.19.0

I hope that with this I can help other users.

Thanks to all.

works for me! thanks @kensodemann ! 😃

As per https://github.com/apache/cordova-plugin-console

This plugin is no longer being worked on as the functionality provided by this plugin is now included in cordova-ios 4.5.0 or greater, and support is already built in to cordova-windows > 5.0.0. You should remove this plugin from your applications.

does anybody still have this problem ? from a gresh new app I'm not able to use this plugin...

Solution from @nuno works for me as well.

ionic cordova plugin remove cordova-plugin-console

• Hit the above command to get ios build success.
