Summary:
It's well known that IBInspectable only supports the following types:
Int
CGFloat
Double
String
Bool
CGPoint
CGSize
CGRect
UIColor
UIImage

It would be awesome if we can have support for enum as well :/ 
This is important as the only possible workarounds are messy and bad, really bad. (Ex: using NSInteger or NSString)

Steps to Reproduce:
1- Create a class called "CustomLabel"

2- Create an enum called "DateFormat" and set three options (Short, Medium, Full)
enum DateFormat: Int {
 case Short // 05/27/2017
 case Medium // May 27,2017
 case Full // May 27, 2017 9:10 AM
}

3- Create a var called format, a DateFromat enum with IBInspectable capability
 class CustomLabel: UILabel {
   @IBInspectable
   var format: DateFormat = .Short {
     didSet {
       // update label
     }
   }
}

4- Go to your storyboard
5- Drag a UILabel to your view controller
6- Set its class to CustomLabel from the attribute inspector
7- Look for the new attribute "format" in the label's attribute inspector

Expected Results:
See an attribute called "format" that is an enum with three options (Short, Medium, Full)

Observed Results:
No new attributes for CustomLabel were added. Enums are not yet supported as IBInspectable
