Undefined symbols for architecture arm64 “_OBJC_CLASS_$_SFSafariViewController”

Question

I am trying to integrate Google sign in into my iOS app. I have followed instructions mentioned by Google.

I have added SafariService.framework as well.

Answer 1

Since the SafariServices framework is only available on iOS9 and above, is it possible that you are trying to run this on a device with iOS lower than that? If so, is it possible that when you added the framework, you added it as required (making it impossible for the app to run on older versions of iOS)? Try setting it as optional (attaching an image to better explain what I mean).
