Found the problem - your MusicLibrary is incomplete. I've amended the code and uploaded to Github and sent a pull request. I've added:

"largeIcon": "ball_large.pdf",
"backgroundColor": ["red": 255, "green": 102, "blue": 153, "alpha": 1.0],
"artists": ["Shakira", "Santana", "Wyclef Jean", "Aloe Blacc", "Pitbull", "Enrique Iglesias", "Ricky Martin"]

to your Playlist.swift file. You were getting a nil as you unwrapped largeIcon because it isn't in your code. A quick check through the debugger showed that the issue was with largeIcon so I checked the basics first, like does it exist! It didn't - problem solved!

Log back into Github and merge the changes, then pull that down to your machine - should work fine.

Steve.
