URI HTTPS request

Thanks Steve. I like the comment, your code will break :) straight to the point. Reworked it; this is better yes? Also added the check and disabled signup parameter! your help much appreciated!!

 var tokenDict : [String:String] = [:]

    func webView(webView: WKWebView, didFinishNavigation navigation: WKNavigation!) {

        if (webView.URL?.scheme == "https" && webView.URL?.host == "www.dropbox.com" && webView.URL?.path == "/1/oauth2/redirect_receiver") {

            //print(webView.URL?.fragment)

            let tokenText = String(UTF8String: webView.URL!.fragment!)

            let parsedTokens = tokenText?.componentsSeparatedByString("&")

            //print("tokenText \(parsedTokens)")

            for token in parsedTokens! {

                let tokenP = token.componentsSeparatedByString("=")

                tokenDict[tokenP[0]] = tokenP[1]

            }

            if (tokenDict["state"] == token2Verify) {

                token2Save = tokenDict["access_token"]!

                let defaults = NSUserDefaults.standardUserDefaults()

                defaults.setObject(token2Save, forKey: "dropBoxAuth")

            }

        }

        progressView.setProgress(0.0, animated: false)

    }
