Use different GoogleService-Info.plist for different build schemes

Question

I am using a build scheme for prod and one for staging (with 2 different bundle identifiers) and I am trying to use a separate GoogleService-Info.plist for each scheme. Is t

Answer 1

With Xcode 9.2, I have needed files for both targets to be named "googleServiceInfo.plist" but placed in different directories, with the directory/file for each target specified in "Build Phases", "Copy Bundle Resources".

The above was not my preferred solution, but I had previously tried using different filenames along the lines of @inidona's answer, converted to Swift 4:

 let filePath = Bundle.main.path(forResource: "googleServiceInfo-Pro", ofType: "plist")!
 let options = FirebaseOptions(contentsOfFile: filePath)
 FirebaseApp.configure(options: options!)

Unfortunately, this did not correct the Firebase error messages. In this question: Firebase iOS SDK - Using configuration file other than GoogleService-Info.plist generates console warning the original poster seems to have fixed by updating the Firebase Pod but I have not confirmed this.
