How to create an IBInspectable of type enum

Question

enum is not an Interface Builder defined runtime attribute. The following does not show in Interface Builder\'s Attributes Inspector:

For 2020 - @SwiftArchitect answer updated for today:

Here's a typical full example with all of today's syntax

import UIKit

@IBDesignable class ClipLabels: UILabel {
    
    enum Side: Int { case left, right }
    
    var side: Side = .left {
        didSet {
            common()
        }
    }
    
    @available(*, unavailable, message: "IB only")
    @IBInspectable var leftRight01: Int {
        get {
            return self.side.rawValue
        }
        set(index) {
            self.side = Side(rawValue: index) ?? .left
        }
    }
    

and just an example of use ...

switch side {
    case .left:
        textColor = .red
    case .right:
        textColor = .green
    }

For this critical Swift/iOS QA,

• the very old answer of @SwiftArchitect is perfectly correct but

• I've just updated it and added the critical "unavailable" thing, which is now possible in Swift.
