Xcode Storyboard Shows Blue Frames Around UI Elements. How do I turn this off?

Question

I\'m honestly not sure what I did here. I\'ve never seen this before. Xcode is now showing blue frames around every UI Element in my Storyboard. This goes for ALL View Controlle

Answer 1

In Xcode 9, turn off Editor->Canvas->Show Bounds Rectangles. The rectangles still don't disappear. Turn it back on, and then turn it off again, and the problem should be resolved.
