UnityAdmobPlugin with iOS Build Failure with Google Mobile Ads SDK 9.14.0

Try to build an iOS app with Google Mobile Ads (Unity) 7.3.1. Observe that during CocoaPods dependency resolution, it pulls the Google Mobile Ads (iOS) SDK version 9.14.0. The following error is thrown in XCode:

▸ Linking UnityFramework ❌ duplicate symbol '_OBJC_IVAR_$_GADPAIDIdentifier._identifier' in > GoogleMobileAds(GADPAIDIdentifier.o) > unity-plugin-library.a(GADPAIDIdentifier.o) ❌ duplicate symbol '_OBJC_CLASS_$_GADPAIDIdentifier' in > GoogleMobileAds(GADPAIDIdentifier.o) > unity-plugin-library.a(GADPAIDIdentifier.o) ❌ duplicate symbol '_OBJC_METACLASS_$_GADPAIDIdentifier' in > GoogleMobileAds(GADPAIDIdentifier.o) > unity-plugin-library.a(GADPAIDIdentifier.o) ❌ duplicate symbol '_OBJC_IVAR_$_GADPAIDIdentifier._timestamp' in > GoogleMobileAds(GADPAIDIdentifier.o) > unity-plugin-library.a(GADPAIDIdentifier.o) ❌ duplicate symbol '_OBJC_IVAR_$_GADPAIDManager._userDefaults' in > GoogleMobileAds(GADPAIDManager.o) > unity-plugin-library.a(GADPAIDManager.o) ❌ duplicate symbol '_OBJC_CLASS_$_GADPAIDManager' in > GoogleMobileAds(GADPAIDManager.o) > unity-plugin-library.a(GADPAIDManager.o) ❌ duplicate symbol '_OBJC_METACLASS_$_GADPAIDManager' in > GoogleMobileAds(GADPAIDManager.o) > unity-plugin-library.a(GADPAIDManager.o) ❌ duplicate symbol '_OBJC_IVAR_$_GADPAIDManager._storageAllowed' in > GoogleMobileAds(GADPAIDManager.o) > unity-plugin-library.a(GADPAIDManager.o) ❌ duplicate symbol '_OBJC_IVAR_$_GADPAIDManager._PAIDV2' in > GoogleMobileAds(GADPAIDManager.o) > unity-plugin-library.a(GADPAIDManager.o) ❌ duplicate symbol '_OBJC_IVAR_$_GADPAIDManager._PAIDV1' in > GoogleMobileAds(GADPAIDManager.o) > unity-plugin-library.a(GADPAIDManager.o) ❌ ld: 10 duplicate symbols for architecture arm64 ❌ clang: error: linker command failed with exit code 1 (use -v to see invocation)

I'm having the same problem. Did you figure out a workaround? I have been stuck on this for a couple of days.

Update: downleveling to Mobile Ads (Unity) 7.3.0 solved the issue.

Installing the Google Mobile Ads Unity Plugin v7.3.0 (https://github.com/googleads/googleads-mobile-unity/releases/tag/v7.3.0) worked for me as well.

Hello everyone,

 

@Fausto & John, thank you for sharing your inputs.

 

@Phandi, Would you be able to confirm if the issue on your end happens only using the latest Google Mobile Ads (Unity) 7.3.1 version? You may try to downgrade to 7.3.0 version for the meantime as a workaround suggested by Fausto. Nonetheless, we would require the below information for the reported behavior:

• Sample app where the issue is reproducible
• Steps to replicate the reported behavior or video screen recording of the issue
• complete stacktrace
