swift - How to do if pattern matching with multiple cases?

Question

I'm searching for the syntax to do pattern matching with multiple cases in an if case statement. The example would be this:

enum Gender {
    case Male, Female, Transgender
}

let a = Gender.Male

Now I want to check, if a is .Male OR .Female. But I would like to avoid using switch for this. However the switch statement would be like this:

switch a {
case .Male, .Female:
    // do something
}

Is it possible to write this with if case? I would expect this, but it didn't work :(

if case .Male, .Female = a {

}

Answer 1

A simple array does the trick:

if [.Male, .Female].contains(a) {
    print("Male or female")
} else {
    print("Transgender")
}

I'm simply amazed at Swift's ability to infer type. Here, it gets that .Male and .Female are of type gender from a.
