request authorize error

[masfu]

i have found some problem with string url encoding

        let url:String! = self.oauth2Settings.authorizeURL + "?response_type=code&client_id=" + self.oauth2Settings.clientID + "&redirect_uri=" + self.oauth2Settings.redirectURL.addingPercentEncoding(withAllowedCharacters: NSCharacterSet.urlHostAllowed)! + "&scope=" + self.oauth2Settings.scope + "&state=" + expectedState
        
        let urlRequest : NSURLRequest = NSURLRequest(url: NSURL(string: url)! as URL)
        
        self.webView!.loadRequest(urlRequest as URLRequest)

converting string to NSURL will raise nil error, i have solution to add

 `   let urlRequest : NSURLRequest = NSURLRequest(url: NSURL(string: url.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)!)! as URL)`

thank you very much

i tried your sugestion, but then the redirect url is also encoded. Because of that I got an error when doing the google oauth.

What was the url string that caused the error in your case?
