Sample Project not working for me

[CodeRed-Tim]

I downloaded the sample project and added in my redirectURL, client id and client secret. Added the correct URL type in the info tab. The app launches, I press the login button, it takes me to Spotify and I authorize it successfully and then takes me back to the login screen and nothing else happens. The loginSuccessful() method is never called. Please help

On iOS above version 13, redirect should be done NOT in appdelegate BUT in scenedelegate.
So the below code should be added in scenedelegate, NOT in appdelegate. (the explanation in README.md was not updated, i think)

func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
     guard let url = URLContexts.first?.url else {
            return
     }
     let handle = SpotifyLogin.shared.applicationOpenURL(url) { (error) in }
     return
}

I don't know if it works. but hope it will work.
