How to cast arc4random() to Int in SWIFT

+1 vote

How to convert arc4random() to Int , i tried as below but it throws error

 var items = Color[]()
 var i = Int(arc4random()) % items.count

and the colour is enum type

enum Color: Int {
    case Red, Green, Blue

The error is EXC_BAD_INSTRUCTION. Checking the debugger shows items is size=1 and [0] = (AppName.Color) (0x10).
