Switch over multiple variables

SwitchTuple.swift

import Foundation

enum FooEnum {
    case foo1
    case foo2
    case foo3
}

enum BarEnum {
    case bar1
    case bar2
    case bar3
}

struct BazStruct {
    let enum1: FooEnum
    let enum2: BarEnum
}

let baz = BazStruct(enum1: .foo1, enum2: .bar3)

switch (baz.enum1, baz.enum2) {
case (.foo1, .bar3):
    print("foo1 and bar3 case")
case (.foo2, .bar3):
    print("foo2 and bar3 case")
case (.foo3, .bar1):
    print("foo3 and bar1")
default:
    print("all other cases")
}

// prints:
// foo1 and bar3 case
