XCode 12, FIRAnalyticsConnector, Build Error

Question

After upgrading to XCode 12, my project doesn\'t build for the simulator anymore.

The error I get is:

ld: in ... /Pods/FirebaseAnalytics/Frameworks/FIRAnal         


        

Answer 1

Ok, I finally found a fix for the issue.

Change "Build Active Architecture Only" to "Yes" also for "Release".
The setting can be found selecting your project > "Build Settings" > "Targets" (your target) > "Architectures"

Please note that the problem is not related to Firebase. I'll still leave it since it might lead others to this issue and help them to resolve this.
