Authorizing on Twitch doesn't redirect back to app (OAuthSwift)

Question

I'm using OAuthSwift to send the user to Twitch to authorize my app. However, once the app is authorized, the user isn't sent back to my app. I get a message that appears in Safari:

You are about to leave Twitch. Twitch has no control over the content or security of http://localhost.

I tried to handle this in the AppDelegate but it doesn't seem to be redirecting:

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey  : Any] = [:]) -> Bool {
    if (url.host == "http://localhost") {
        OAuthSwift.handle(url: url)
    }
    return true
}

Here's the code that fires the Twitch auth:

@IBAction func didPressLoginButton(_ sender: Any) {

    // create an instance and retain it

        let oauthswift = OAuth2Swift(
            consumerKey:    "xxxxx",
            consumerSecret: "xxxxx",
            authorizeUrl: "https://id.twitch.tv/oauth2/authorize",
            accessTokenUrl: "https://id.twitch.tv/oauth2/token",
            responseType:   "code",
            contentType:    "application/json"
        )

        oauthswift.authorizeURLHandler = OAuthSwiftOpenURLExternally.sharedInstance

        self.oauthswift = oauthswift

        //oauthswift.accessTokenBasicAuthentification = true
        //let codeVerifier = base64url("abcd...")
        //let codeChallenge = codeChallenge(for: codeVerifier)

        let handle = oauthswift.authorize(withCallbackURL: URL(string: "http://localhost")!, scope: "user:read:email", state:"TWITCH") { result in

            switch result {

                case .success(let (credential, response, parameters)):
                    print(credential.oauthToken)
                    TwitchTokenManager.shared.accessToken = credential.oauthToken
                    //Twitch.Clips.getClips

                // Do your request

                case .failure(let error):
                    print(error.localizedDescription)
            }
        }
    }

Any help would be greatly appreciated. Thanks :)

Have you entered your redirect URI in dev console? – Hikarunomemory Jan 16 '20 at 06:42 — Hikarunomemory, Jan 16 '20 at 06:42

Mine said this in Android (not sure it will help) but turns out, I had the wrong Client ID entered into my webview.

Once i changed it to the right client ID that was in the Twitch dev dashboard, it pulled up the auth page. Also, I am using my home URL as the redirect, not localhost. Not sure if that made a difference either. Good luck!!
