Fatal error: Unexpectedly found nil while unwrapping an Optional value

In my PlaylistMasterViewController.swift file, on the line of code:

playlistImageView0.image = playlist.icon

I have the error:

Thread 1: EXC_BAD_INSTRUCTION (code=EXC_1386_INVOP, subcode=0x0)

In my console output, I have the following lines:

Unknown class Playlist in Interface Builder file.

CUICatalog: Invalid asset name supplied:

Could not load the "" image referenced from a nib in the bundle with identifier "com.jdpruitt.Algo-Rhythm"

fatal error: unexpectedly found nil while unwrapping an Optional value (lldb)

Hiya,

What is in your JSON for the zero playlistImageView? It looks as though it has pulled back "" or the image isn't available. Your asset should have coffee.pdf in there for that icon.

Hi Steve,

Ah, thank you ... you helped me realize that I had a broken IBOutlet at:

@IBOutlet weak var playlistImageView0: UIImageView!

Deleted and re-connected it. (Hope I'm using the correct terminology!)

Thanks so much for your help!
