macOS Program crashes before IB file is one loading

[ryanknu]

I don't even know where to begin with this one, the program built and ran before, then I changed a method in a class and now the program can't get past loading the interface before crashing. Here's a crash log. I honestly have no idea how this could have happened.

I made an error, it seems that IB does load but somewhere along the line my code messes something up.
