UIKit UISwipeGestureRecognizer in Xcode crashes app during nib loading?

Question

I've added a UISwipeGestureRecognizer to my Xcode nib and having it there makes my app crash with:

..exception 'NSInvalidArgumentException', reason: '-[UISwipeGestureRecognizer initWithCoder:]: unrecognized selector sent to instance 0x5c2ab30'.

Why?

Are you running it on the wrong version of iOS? – Expansion

@jtbandes: ugh yes. I'm using 5.0 sdk and was using 4.3.x simulator. That's unfortunate.. why would this issue exist? How should I address it? – Destruction

Answer 1

This is happening because you're running the app on the wrong version of iOS. You can't put gesture recognizers in a xib file on iOS <5, so you'll have to create them in code if you want to support older versions of iOS.
