ios app rejected on using AWS cognito implementation from mobile hub - facebook

Question

We recently got our ios app rejected because of the following:
We noticed that the user is taken to Safari to sign in or register for an account, which provides a poor user experience.
however, the bit that launches the safari window for facebook/Google login is part of the AWSMobileHubHelper framework so we can't modify that code.
Any ideas/solutions would be greatly appreciated.

So I found a workaround. I just grab the GIDSignIn instance and change the properties myself. In case any one else wants to know how, all you have to do is:
Add a bridge header and import #import <GoogleSignIn/GoogleSignIn.h>
Implement the presentViewController method for GIDSignInUIDelegate on your main login controller
func signIn(signIn: GIDSignIn!, presentViewController viewController: UIViewController!) {
presentViewController(viewController, animated: true, completion: nil)
}
Edit demo login code to be something like this:
func loginWithGoogle(delegate: GIDSignInUIDelegate!) {
let googleProvider = AWSGoogleSignInProvider.sharedInstance()
// It is important that these are initialized after
// AWSGoogleSignInProvider.sharedInstance() is called
GIDSignIn.sharedInstance().uiDelegate = delegate
GIDSignIn.sharedInstance().allowsSignInWithBrowser = false
GIDSignIn.sharedInstance().allowsSignInWithWebView = true
handleLoginWithSignInProvider(googleProvider, callback: callback)
}

As of iOS 9 using Facebook SDK, this is expected behavior per Facebook login. Mobile Hub quickstart app is just applying the Facebook SDK 3 and using the APIs as directed. Check out the brief description below and read through the comments to get a better insight. This was not a popular decision by Facebook and others have provided workarounds (to forcing user authentication via mobile browser) if you wish to experiment. As for the AWSMobileHubHelper framework, we are looking into making this available at some point but don't have a timeline for this.
"Logic that automatically defaults people to the optimum experience for iOS 9. This means that the SDK dialogs for Facebook Login, Sharing across Facebook and Messenger, App Invites, App Events, or Native Like will automatically determine the best experience for people based on their device."
