title: iOS Twitter Kit usage gets error 'Request failed: forbidden'
body: <p>I have quite similar issue <a href="https://stackoverflow.com/questions/29365616/how-to-login-with-digits-user-of-twitter-kit-in-objective-c/32635803#32635803">to this one</a> and I cannot find an answer as that question wasn't solved. </p>
  
  <p>The problem is that I get this in Xcode's console after setting up Twitter Kit and Fabric, adding secret and api keys for twitter to plist:</p>
  
  <blockquote>
    <p>Error Domain=TwitterAPIErrorDomain Code=200 "Request failed: forbidden
    (403)" UserInfo=0x7fdd9ac48ef0
    {NSErrorFailingURLKey=<a href="https://api.twitter.com/1.1/guest/activate.json" rel="nofollow noreferrer">https://api.twitter.com/1.1/guest/activate.json</a>,
    NSLocalizedDescription=Request failed: forbidden (403),
    NSLocalizedFailureReason=Twitter API error : Forbidden. (code 200)}</p>
  </blockquote>
  
  <p>My code that uses Twitter Kit and produces the error mentioned above:</p>
  
  <pre><code>NSString *userID = [Twitter sharedInstance].sessionStore.session.userID;
  TWTRAPIClient *client = [[TWTRAPIClient alloc] initWithUserID:userID];
  
  [client loadUserWithID:kTwitterUser completion:^ (TWTRUser *user, NSError *error) {
       if (error) {
          NSLog(@"ERROR CARL %@", error);
       } else {
          NSLog(@"User %@", user);
       }
  }];
  </code></pre>
