swift : Enum constant with type and value

Question

I know, enumeration constant should be like this in swift

enum CompassPoint {
    case North
    case South
    case East
    case West
}

But how can I assign value to first element, like Objective-C code as below

enum ShareButtonID : NSInteger
{
   ShareButtonIDFB = 100,
   ShareButtonIDTwitter,
   ShareButtonIDGoogleplus

}ShareButtonID;

Solution

You need to give the enum a type and then set values, in the example below North is set as 100, the rest will be 101, 102 etc, just like in C and Objective-C.

enum CompassPoint: Int {
    case North = 100, South, East, West
}

let rawNorth = CompassPoint.North.rawValue // => 100
let rawSouth = CompassPoint.South.rawValue // => 101
// etc.

Update: Replace toRaw() with rawValue.

toRaw() has been replaced with rawValue
