Storyboard uiviewcontroller, 'custom class' not showing in drop down

Question

I have a UIViewController I created in my apps storyboard, as well as a custom UIViewController subclass which I added to the project (and is correctly in the compile phase

Answer 1

In Xcode 8, a few of my classes had the wrong path (case sensitive) specified for their file locations.

MyProject/mysubdirectory/MyViewController.xib (.m, .h)

vs:

MyProject/MySubdirectory/MyViewController.xib (.m, .h)

Really not sure how it ended up in that state, but my project exhibited the exact same behavior as above (no outlets/actions displaying in IB), and fixing that path fixed the problem.

I fixed this two different ways. One way was by I opened the .pbxproj file and fixing the case sensitive issue manually. The other way that worked was by tapping the folder icon under the Identity and Type section of the File Inspector tab of the file, and re-selecting the file there.
