Currying in Swift

Currying.playground

func twoWords(a: String) (b: String) -> String {
  return "\(a) \(b)"
}

twoWords("Hello")(b: "Ayaka") // Note that you need to explicitly name your second parameter

// Now for currying...
let greet = twoWords("Hello")

greet(b: "Ayaka")
greet(b: "World")

func threeWords(a: String) (b: String) (c: String) -> String {
  return "\(a) \(b) \(c)"
}

threeWords("Hello")(b:"World")(c:"!")

let helloWorld = threeWords("Hello")(b: "World")
helloWorld(c: "!")
