"wait_fences: failed to receive reply: 10004003"?

I get this cryptic error the first time (and only the first time) my view is loaded due to the following line of code:

- (void)viewWillAppear:(BOOL)animated
[textField becomeFirstResponder];

There is a noticeable (~3 – 4 second, even on the simulator) delay due to this that makes my app feel unresponsive. Does anyone know how to fix this? I can't find any documentation on it on Apple's site, or any solutions here or on Google.

Strangely, the opposite situation happens if I put the line in
instead of
; that is, instead of printing the error only the first time the keyboard is shown and never again, the error is not printed the first time but every time after. This is causing a major headache for me.

Override -viewDidAppear:, not -viewWillAppear, and make sure to call [super viewDidAppear:]. You should not perform animations when you are not on screen ("will appear"). And the -viewDidAppear: docs explain that you must call super because they have their own things to do.
