Cannot find type GIDSignInDelegate and property clientID with Google sign in with firebase [closed]-CodePudding

I follow the guideline of firebase but when I enter code for client ID in AppDelegate, it not accept. Also it not accept the GIDSignInDelegate method.

enter image description here

CodePudding user response：

Since 6.0.0 GoogleSignIn doesn't have a delegate anymore, they've switched to completions(probably to easily support new swift concurrency).

Check out migration guide.

You can use it like this now, in your view controller:

GIDSignIn.sharedInstance.signIn(
    with: "clientId",
    presenting: self // your view controller
) { user, error in
    if let token = user?.authentication.idToken {
        completionHandler(token, nil)
        return
    }
    guard let error = error as? GIDSignInError else { 
        fatalError("No token and no GIDSignInError: \(String(describing: error))") 
    }
    completionHandler(nil, error)
}

In your AppDelegate you need this(just like before):

func application(
    _ app: UIApplication,
    open url: URL,
    options: [UIApplication.OpenURLOptionsKey: Any] = [:]
) -> Bool {
    return GIDSignIn.sharedInstance.handle(openURL)
}
