Firebase includes official documentation for how to do this now. I used this method in my app and it works great.

More specifically, I defined a custom Swift flag "BUILD_TYPE" in XCode and for each scheme, I define a unique value for that flag. Then, in my AppDelegate, I tell Firebase what GoogleService-___.plist file to load at runtime by this Swift flag value:

    let filePath = Bundle.main.path(forResource: "GoogleService-" + Bundle.main.infoDictionary!["BUILD_FLAVOR"] as! String, ofType: "plist")
    guard let fileopts = FirebaseOptions.init(contentsOfFile: filePath!) else {
        fatalError("Couldn't load config file")
    }
    FirebaseApp.configure(options: fileopts)
