Interface Builder Views not showing up

Question

All of my view controllers suddenly had this bug. Nothing shows up in interface builder, but it works fine when I run it. This makes it so I can't edit my views in interface builder. Whats going on here? Xcode 6.1 GM ios 8.1 B1. Swift.

Answer 1

I assume you made your design in a size class other than wAny / hAny. Switch back to the size class you used for design and your controls will reappear.

Answer 2

This happens when you press Command+Delete, meant for removing objects from only certain size classes. If you just did it, you can undo it, but otherwise I looked around and I can't find a way to turn them back on. The only menu references to it are after you press Command+Delete to "Undo Turn Off", so it may be a bug right now unless theres an alternative way to turn the layers back on.
