Swift Overloading on a Function's Return Type

Return Type Overloading.swift

// Note these divide functions both except identical inputs

func divide(a: Int, b: Int) -> Int {
    return a / b
}

func divide(a: Int, b: Int) -> Float {
    return Float(a) / Float(b)
}

// and Swift figures out which one to use magically!

let x: Int = divide(3, 2)
let y: Float = divide(3, 2)

println(x) // -> 1
println(y) // -> 1.5
