The most common reason for this error is naming the Xcode project something slightly different than the .momd file. For example, did you name your project “Hit List” instead of “HitList”? That would cause this problem.
Great tutorial. Am I missing the step where the tableview outlet gets connected on the main storyboard? I didn’t trust my eyes, so I searched for “tableview” and “outlet,” but came up blank. Anyway, it was an easy control-drag fix, but I was wondering if anyone else caught it and never mentioned it in the comments?
Again, it may be my eyes playing tricks on me … 
This tutorial should be updated to swift 3 and xcode 8.
Many errors are coming.
