React-native-onesignal: IOS Build Failing with: "ld: library not found for -lreact-native-onesignal"

Description:

Followed the React Native & Expo SDK Setup guide. After completing step 5, I attempted to build my app in XCode. The build failed with the following error:

ld: library not found for -lreact-native-onesignal
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I tried following the manual linking steps but hit the same error. Wondering anyone figured out a solution to this?

Thanks!

Environment

• Added SDK to project with yarn add react-native-onesignal
• react-native-onesignal: 4.0.3
• react-native: 0.63.3
