could not find a valid GoogleService-Info.plist in your project - iOS, Swift, Objective-C

*** Terminating app due to uncaught exception 'com.firebase.core', reason: '`[FIRApp configure];` (`FirebaseApp.configure()` in Swift) could not find a valid GoogleService-Info.plist in your project. Please download one from https://console.firebase.google.com/.'
***

Solution 1:

Check the downloaded plist file name. The correct name should be 'GoogleService-Info.plist'.

Some names like GoogleService-Info(3).plist, GoogleService-Info(5).plist are invalid.

Firebase App configuration looks for the 'GoogleService-Info.plist' file. If the name is invalid and the app will crash with the above error.

So change name and Run, it should works without any error.

Solution 2:

Even though changing the name app still crashing then check the selected target for 'GoogleService-Info.plist'

For that first select 'GoogleService-Info.plist' file.

Next in the right side panel of Xcode, select 'file inspector'. There we can see 'Target Membership' check our target.

Now try Build and Run,it should works without any error.
