Google + login iOS App rejection from appstore using google sdk v3.x

Finally the problem is sorted out with latest Google+ Sign SDK and the app is also approved by Apple. I am posting a solution for both iOS 9 and iOS 8.
Use CocoaPods for integration.

pod 'Google/SignIn'

To start with login you have to do exactly the same steps mentioned in the Start Integrating Section here

Now in the Add Sign-In part, I want some custom button in my custom class of UIViewController to initiate the login process. In the developer link of Google, they are redirecting in AppDelegate only. So to avoid this I will not be using GIDSignInDelegate in my AppDelegate class

I will only be making changes in the following two methods of AppDelegate

//This is available for iOS 9 and above. So we have to use this method if we are integrating Google Sign In in iOS 9
func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject])

//This is available prior iOS 9 and is available for iOS 8,7 etc. This is a deprecated method for iOS 9. You have to override this too if your app supports iOS 8 platform.
func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool

So the definitions will be as follows:

func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {

    if #available(iOS 9.0, *) {
        return GIDSignIn.sharedInstance().handleURL(url, sourceApplication: options[UIApplicationOpenURLOptionsSourceApplicationKey] as? String, annotation: options[UIApplicationOpenURLOptionsAnnotationKey] as? String)
    } else {
        // Fallback on earlier versions
    }
    return true
}

func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool {

    return GIDSignIn.sharedInstance().handleURL(url,sourceApplication: sourceApplication,annotation: annotation)
}

Now moving on to our Custom UIViewController class i.e LoginViewController, implement the GIDSignInDelegate and GIDSignInUIDelegate

class LoginViewController: UIViewController, GIDSignInDelegate, GIDSignInUIDelegate {

}

There is a custom UIButton for Google + login whose definition is

@IBAction func googleLoginButtonPressed(sender: AnyObject) {

    // Initialize sign-in
    var configureError: NSError?
    GGLContext.sharedInstance().configureWithError(&configureError)

    //assert(configureError == nil, "Error configuring Google services: \(configureError)")
    if configureError != nil {
     //Handle your error
    }else {
        GIDSignIn.sharedInstance().shouldFetchBasicProfile = true
        GIDSignIn.sharedInstance().clientID = kClientId
        GIDSignIn.sharedInstance().delegate = self
        GIDSignIn.sharedInstance().uiDelegate = self

        //This did the trick for iOS 8 and the controller is presented now in iOS 8
        //We have to make allowsSignInWithBrowser false also. If we dont write this line and only write the 2nd line, then iOS 8 will not present a webview and again will take your flow outside the app in safari. So we have to write both the lines, Line 1 and Line 2
        GIDSignIn.sharedInstance().allowsSignInWithBrowser = false  //Line 1
        GIDSignIn.sharedInstance().allowsSignInWithWebView = true   //Line 2

        GIDSignIn.sharedInstance().signIn()
    }

}

Now the implementation of delegate methods for Google + Sign In

func signIn(signIn: GIDSignIn!, dismissViewController viewController: UIViewController!) {
    self.dismissViewControllerAnimated(true) { () -> Void in       
    }
}

func signIn(signIn: GIDSignIn!, presentViewController viewController: UIViewController!) {
    self.presentViewController(viewController, animated: true) { () -> Void in
    }
}

func signIn(signIn: GIDSignIn!, didSignInForUser user: GIDGoogleUser!, withError error: NSError!) {
    if (error == nil) {

        // Perform any operations on signed in user here.
        let userId = user.userID                  // For client-side use only!
        let idToken = user.authentication.idToken // Safe to send to the server
        let fullName = user.profile.name
        let givenName = user.profile.givenName
        let familyName = user.profile.familyName
        let email = user.profile.email
    } else {
        print("\(error.localizedDescription)")
    }
}

func signIn(signIn: GIDSignIn!, didDisconnectWithUser user: GIDGoogleUser!, withError error: NSError!) {
      //Perform if user gets disconnected
}

Now this will work in both iOS 8 and 9 without moving your app outside to Safari for Login purpose in Google +.
