Problem with gesture

I tried this code ......

self.swipeRecognizer = [UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFrom:);
swipeRecognizer.direction = UISwipeGestureRecognizerDirectionLeft;
self.view addGestureRecognizer:swipeRecognizer;

It works fine in the simulator, but while working with the device I get the following error:

Where am I going wrong?

On which device are you trying to run this project as UIGestureRecognizer is available from iOS 3.2 and above.
