Using Google Sign-in with two targets

Question

I have a problem that I can't figure out, and I've searched everywhere.

I recently added Google Sign-in to my app, and it's working fine on the main target, however, since I'm using multiple targets to deploy a secondary version of my app, the second bundle identifier can't get added to "GoogleService-Info.plist". The Google sign-in code refers to this file by name, so I can't simply change the name for each version of the app like I've done for other plists.

I've tried adding environment variables to each scheme and using ${BUNDLE_ID} in the plist to change based on the chosen scheme, but it's not working either. Is there something I'm missing? How should a workspace with multiple targets use the same plist with different variables for each target?

Thanks!

Edit: Tried using an XCConfig file to replace the static values in the plist with compile-time variables. No luck, probably because I think Google Sign-in is accessing the file directly. I assume anyone using Google Sign-in with an app that has multiple targets (ad-supported vs. paid premium) must have a way around this. Please help.

Answer 1

I had the same problem and I found a pretty simple solution.

Just copy the GoogleServices-Info.plist and put it in a different folder. The folder must be a physically different folder, since the filesystem won't accept same file names in the same folder. So create a real folder in finder and add it to XCode, don't use XCode groups.

Then change the target membership according to each plist file. Thats it!
