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

You can build a struct that conforms to the RawOptionSet protocol, and you'll be able to use it like the built-in enum type but with bitmask functionality as well. The answer here shows how: Swift NS_OPTIONS-style bitmask enumerations.
