It won't let me use the simulator, it says Thread 1: signal SIGABRT.

It does this while highlighting: class AppDelegate: UIResponder, UIApplicationDelegate

Thanks

You may have deleted a line of code and forgot to disconnect it on the storyboard.

Check out this video

Also you may need to reset your content and settings in the simulator.

I was having the same issue. If click on the ViewController and go into Identity Inspector. While my Class was correct my Module box was empty. I selected Algorythm (the only option I had) and then everything ran just fine.

I had the same error. Nothing from the above worked. The solution was to delete the button, and then add it again, but exactly like in the treehouse video - with option Type: AnyObject and Arguments: None.
