When I "ctrl click and drag" in xcode interface builder, it says "File Owner" rather than my custom UIView

When I "ctrl click and drag" in xcode interface builder, it says "File
Owner" rather than my custom UIView

When I did it earlier with a UILable, the "referencingOutlet" was my
custom UIView (called LocDebugView).
When I do it now, either with the original UILabel or a new one, it says
"File's Owner".
When I try to run the code with "File's Owner", it crashes, saying "his
class is not key value coding-compliant for the key npcsView.'" or
whatever I try to name the new variable.
What happened? What changed? How can I fix it?
