IB Designables: Failed to render and update auto layout status

Question

I have a custom view (xib) that has a UIButton inside of it, I made id IBDesignable doing the following:

UserView.swif

Answer 1

Unfortunately, you can't use IBOutlets within a IBDesignable. Better answer for you here:

Live Render IBOutlet Connected Subviews Via IBInspectable Properties

Perhaps you wanted to have your UserView extend UIButton, rather than UIView?
