Declaring and using a bit field enum in Swift

Question

How should bit fields be declared and used in Swift?

Declaring an enum like this does work, but trying to OR 2 values together fails to compile:

enum         


        

Answer 1

Do bitwise operation using raw value then create a new enum object using the result.

let mask = UIViewAutoresizing(rawValue: UIViewAutoresizing.FlexibleWidth.rawValue|UIViewAutoresizing.FlexibleHeight.rawValue) self.view.autoresizingMask = mask
