@IBInspectable with enum?

Question

I\'d like to create @IBInspectable element as you see at the picture below :

Answer 1

That's not possible (for now). You can only use those types that you see in User Defined Runtime Attributes section.

From Apple's doc:

You can attach the IBInspectable attribute to any property in a class declaration, class extension, or category for any type that’s supported by the Interface Builder defined runtime attributes: boolean, integer or floating point number, string, localized string, rectangle, point, size, color, range, and nil.
