fixed by

pod 'Google/SignIn'

[akyGit]

If you choice manual install, without pods:

1. react-native install react-native-google-signin
2. Drag and drop all files from /node_modules/react-native-google-signin/ios/GoogleSdk directory that end with .framework into the Frameworks group of application and check "Copy items if needed" is ticked.
3. Go to "Build Settings" and add to "Framework Search Paths" path to GoogleSdk: default $(PROJECT_DIR)/../node_modules/react-native-google-signin/ios/GoogleSdk
4. Now try to build your application again

I have same Issue? How can you solve it?

[maplefu0601]

Solved this issue with pod.

1. remove your googleSignIn.bundle from Xcode-->build phases-->copy bundle resources
2. go to your xcode project
3. pod init
4. open Podfile and add pod 'GoogleSignIn', save the file and exit
5. pod install
6. go back to your root project folder
7. react-native run-ios
