Xcode 12: build Error on FIRAnalyticsConnector

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

The error I get is:

ld: in ... /Pods/FirebaseAnalytics/Frameworks/FIRAnalyticsConnector.framework/FIRAnalyticsConnector(
FIRAnalyticsConnector_e321ed8e3db06efc9803f6c008e67a34.o), 
building for iOS Simulator, but linking in object file built for iOS, file
'.../Pods/FirebaseAnalytics/Frameworks/FIRAnalyticsConnector.framework/FIRAnalyticsConnector'
for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

A workaround is adding arm64 to my project > Build Settings > Excluded Architectures, but then it won't build for my real device.

I already tried cleaning the build folder, updating pod file, restarting etc.

I'm using:

Any ideas?

Solution

  • 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.
