Answer 1

Both Igor and Spydy worked for me

A swift version of Igor's post

    GIDSignIn.sharedInstance().uiDelegate = self

    GIDSignIn.sharedInstance()?.hasAuthInKeychain()
    GIDSignIn.sharedInstance()?.signIn()

    // Uncomment to automatically sign in the user.
    GIDSignIn.sharedInstance().signInSilently()

or from Spydy.

    // google sign in setup
    GIDSignIn.sharedInstance().uiDelegate = self
    if GIDSignIn.sharedInstance().hasAuthInKeychain() == true{
        GIDSignIn.sharedInstance().signInSilently()
    }
    else{
        GIDSignIn.sharedInstance().signIn()
    }
