I'm toying around with SpriteKit and using SKS files to construct scenes. I've started with the stock Game project and added one extra SKS file and a class to go along with it. My class will attempt to load the SKS file to build its scene just like the stock files do. However, when I go to the GameViewController and actually try to use my class, I get a runtime error that my SKS file can't be found. I've verified that the SKS file is in the project, is part of the bundle, is visible at runtime from within the bundle, but my class that uses the SKScene initializer to load the file can't see it and I'm not sure why.
