Description:

I've been trying to fix this error for the last couple of hours but I haven't found a way to get around it. I simply trying to Sign in the user to Twitter directly from my iOS app. Here's a snippet of my code.

public final class SignInViewController: UIViewController {

    let oauthswift = OAuth1Swift(
        consumerKey: "#####",
        consumerSecret: "#####",
        requestTokenUrl: "https://api.twitter.com/oauth/request_token?oauth_callback=tweetometer://",
        authorizeUrl: "https://api.twitter.com/oauth/authorize",
        accessTokenUrl: "https://api.twitter.com/oauth/access_token"
    )
    var handle: OAuthSwiftRequestHandle!

    @IBAction func signIn() {
        oauthswift.authorizeURLHandler = SafariURLHandler(viewController: self, oauthSwift: oauthswift)
        handle = oauthswift.authorize(
            withCallbackURL: URL(string: "tweetometer://callback/twitter")!,
            success: { credential, response, parameters in
                print(credential.oauthToken)
                print(credential.oauthTokenSecret)
                print(parameters["user_id"])
                // Do your request
        },
            failure: { error in
                print(error)
        })
    }
}

The HTTP response is a 401 with the following content which may be useful to debug the issue:

requestError[Error Domain=NSURLErrorDomain Code=401 "" UserInfo={OAuthSwiftError.response=<NSHTTPURLResponse: 0x600000a9d060> { URL: https://api.twitter.com/oauth/request_token?oauth_callback=tweetometer:// } { Status Code: 401, Headers {

I have tried inserting my consumer key and secret in the demo app using Xcode 9.3 and it still doesn't work. It may have broken because of the new parameter oauth_callback which needs to be whitelisted in the Twitter developer portal since GDPR was enforced?

I authorized the scheme in my developer portal. I tried to remove it and now it works? But before it was complaining that the callback url must be present, this is what the Twitter documentation also says.

https://developer.twitter.com/en/docs/basics/developer-portal/guides/callback-urls.html
it seems that custom one is authorised now, and there is specific error if not authorized

I have just tested it, and it work fine

Did you use Consumer API keys = oauth1? (not Access token & access token secret = oauth2)
