Google Contacts OAUTH2

Question

I'm trying to fetch Google Contacts but when user login option appears on it shows asks permission for Know your age range and language. But no permissions for contacts. Also when user is logged in successfully it redirects me to google search page.

@IBOutlet weak var signInButton: GIDSignInButton!
var peopleDataArray: Array<Dictionary<NSObject, AnyObject>> = []
override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
    GIDSignIn.sharedInstance().delegate = self
    GIDSignIn.sharedInstance().uiDelegate = self
    GIDSignIn.sharedInstance().clientID = ""

    GIDSignIn.sharedInstance().scopes.append("https://www.googleapis.com/auth/plus.login")
    GIDSignIn.sharedInstance().scopes.append("https://www.googleapis.com/auth/plus.me")

    GIDSignIn.sharedInstance().signInSilently()

}

    task.resume()

URL Scheme

Answer 1

override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
    GIDSignIn.sharedInstance().delegate = self
    GIDSignIn.sharedInstance().uiDelegate = self
    GIDSignIn.sharedInstance().clientID = ""

GIDSignIn.sharedInstance().scopes.append("https://www.googleapis.com/auth/plus.login")
GIDSignIn.sharedInstance().scopes.append("https://www.googleapis.com/auth/plus.me")
GIDSignIn.sharedInstance().scopes.append("https://www.googleapis.com/auth/contacts.readonly")


GIDSignIn.sharedInstance().signInSilently()

}

You need to add these scopes and then try as know you are only asking permission to get your information

 // App Delegate Handle Url Scheme
 open func application(_ application: UIApplication, open url: URL, 
 sourceApplication: String?, annotation: Any) -> Bool {
    var returnScheme: Bool!
    if url.scheme == "dropbox"{
        returnScheme = true
    }else if url.scheme == "Goolge URL SCHEME Which you have added in plist file"{
        returnScheme = GIDSignIn.sharedInstance().handle(url,
                                                         sourceApplication: sourceApplication,
                                                         annotation: annotation)
    }
    return returnScheme
}
