Hi Travis,

Open up your simulator select iOS simulator menu and reset content and settings. Also check your storyboard file for orphan referencing outlets.

This should fix your problem.

tried reseting content and settings, also checked the storyboard file for orphan referencing outlets. no success =(

I tried resetting and beginning the project from scratch, but came into the same problem into the 3rd video =/

the error code appears in an early line of the AppDelegate.swift file

I file I have not edited =/

*** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<UIViewController 0x7f84a0f1f8a0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key aButton.'

Ok Travis,

Here is what I did to fix the program.

  1. Open the storyboard file. Delete ALL referencing outlets for both the image and the button.

reconnect the IBOutlets @IBOutlet weak var aButton: UIButton! (drag this to the button) @IBOutlet weak var playlistImageView0: (drag this to the image)

  1. Remove the push segue and add another one. Don't forget to set the identifier to showPlaylistDetail

I had an orphaned outlet on the image which I deleted manually by removing the variable from the PlaylistMasterViewController instead of going to the connections inspector and removing it from there. Confusing -- hope this helps someone else.
