Getting Name of ObjC Enum in Swift 3?

Question

If an ObjC function returns a status value with enum, is there way to get the string of the enum in Swift 3? If I do debugPrint(\"\\(status)\"), or print(

You can also add conformance of the Obj-C enum to CustomStringConvertible and translate values to strings that way. As long as you don't use default you will be warned if any of these values change in future versions.

For example:

extension NSLayoutAttribute : CustomStringConvertible {
    public var description: String {
        switch self {
        case .left : return "left"
        case .right : return "right"
        case .top : return "top"
        case .bottom : return "bottom"
        case .leading : return "leading"
        case .trailing : return "trailing"
        case .width : return "width"
        case .height : return "height"
        case .centerX : return "centerX"
        case .centerY : return "centerY"
        case .lastBaseline : return "lastBaseline"
        case .firstBaseline : return "firstBaseline"
        case .leftMargin : return "leftMargin"
        case .rightMargin : return "rightMargin"
        case .topMargin : return "topMargin"
        case .bottomMargin : return "bottomMargin"
        case .leadingMargin : return "leadingMargin"
        case .trailingMargin : return "trailingMargin"
        case .centerXWithinMargins : return "centerXWithinMargins"
        case .centerYWithinMargins : return "centerYWithinMargins"
        case .notAnAttribute : return "notAnAttribute"
        }
    }
}
