Can't build Firebase v2.6.0.1on iOS

When I build Firebase with Xcode 11.3.1 it has this error

Undefined symbols for architecture x86_64:
OBJC_CLASS$_GULHeartbeatDateStorage”, referenced from:
objc-class-ref in FirebaseCore(FIRHeartbeatInfo.o)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I used Cocos Creator v2.3.0

Thanks for your feedback.

plz check GoogleUtilities.framework has been added to your project.

Yes it did, I checked this one first.

After restart my Mac, it built success.
