enum Example {
  case Foo(f: String, g: String)
  case Bar(b: Int, c: Int)
}

func printExample(_ example: Example) {
    switch example {
        case .Foo(let f, let g):
            print("Foo: \(f), \(g)")
        case .Bar(let b, let c):

    }
}

let fooExample = Example.Foo(f: "foo", g: "goo")
let barExample = Example.Bar(b: 2, c: 3)

printExample(fooExample) // Foo: foo, goo
printExample(barExample) // Bar: 2, 3
