How to use the package:

• initialize stage:

   import SwiftGoogleSignIn

First of all you need approved scope permission. There are sensitive scopes for Google APIs to have ability to work properly Make sure they are presented in your app. Then send request on verification. After the verification provide them for the initializa method:

   let googleAPIscopes: [String] = ["https://www.googleapis.com/auth/youtube",
       "https://www.googleapis.com/auth/youtube.readonly",
       "https://www.googleapis.com/auth/youtube.force-ssl"]

   func application(_ application: UIApplication,
                    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
      SwiftGoogleSignIn.API.initialize(googleAPIscopes) 
   }

Handle open URL:

   func application(_ application: UIApplication,
                    open url: URL,
                    options: [UIApplication.OpenURLOptionsKey: Any] = [:]
   ) -> Bool {
       return SwiftGoogleSignIn.API.openUrl(url)
   }

• put 'Sign In' button on your Log in screen:

   import SwiftGoogleSignIn

   struct LogInContentView: View {

      var body: some View {
         ...
         SignInButton()
         ...
      }
   }

• subscribe on the User sign in result action:

   SwiftGoogleSignIn.API
       .publisher
       .receive(on: RunLoop.main)
       .sink(
           receiveCompletion: { result in
               if case let .failure(error) = result {
                   // parse the error
               }},
            receiveValue: { session in
               if session.isConnected {
                   // success connect
               } else {
                   // failed connect
               }
            }
        )

Interface:

    func initialize(_ scopePermissions: [String]?)
    /// The Client has to set up UIViewController for Goggle SignIn UI base view
    var presentingViewController: UIViewController? { get set }
    /// Google user's connect state publisher
    var publisher: AnyPublisher<UserSession, SwiftError> { get }
    /// Please use SignInButton view for log in
    func logIn()
    /// Log out. Handle result via publisher
    func logOut()
    /// As optional we can send request with scopes
    func requestPermissions()
    /// The Client has to handle openUrl app delegate event
    func openUrl(_ url: URL) -> Bool
