Add both Google Service plists to your project, with different names:

Then for each Build Scheme, select Edit Scheme and add a unique value for an environment variable like so:

So the other build scheme's BUILD_FOR environment variable would be set to "DEV", for example.

Then, you would check for this variable in App Delegate and configure the FIRApp according to which scheme was built:

    let buildFor = ProcessInfo.processInfo.environment["BUILD_FOR"]! as String
    var firebasePlistFileName = "GoogleService-Info"

    if buildFor == "PROD" {
        firebasePlistFileName = "GoogleService-Prod-Info"
    }

    let firbaseOptions = FIROptions(contentsOfFile: Bundle.main.path(forResource: firebasePlistFileName, ofType: "plist"))
    FIRApp.configure(with: firbaseOptions!)
