How to fix "Undefined symbols for architecture x86_64" Xcode 11

Question

After upgrade 'Google-Mobile-Ads-SDK' (to 7.50.0 was 7.41.0), And run my code I got this Buildtime error:

Undefined symbols for architecture x86_64: “OBJC_CLASS$_GULSwizzler”

I tried to delete DerivedData file, upgrade cocoapods to the lates, clean build, same error

Isn't `GULSwizzler` part of the Firebase SDK? If so you might need to update that too. — trojanfoe, Sep 26 '19 at 07:36
