Swift: Set of Strings and Integers

Strings + Integers

This demo shows one way of implementing a mix of types in a Set.

Code Sample

enum StringOrInt: Hashable, CustomStringConvertible {
    case string(String)
    case int(Int)
    var description: String {
        switch self {
        case .int(let int):
            return String(int)
        case .string(let string):
            return string
        }
    }
}

var mixedSet: Set<StringOrInt> = Set([.string("@lintuxt"), .int(0), .string("@lintuxt"), .int(1)])

print(mixedSet)

/*
    Output: [0, 1, @lintuxt]
*/
