Swiftで新しい演算子を定義する

More than 5 years have passed since last update.
Swift


class MyNumber {
    var value = 0
    init(value: Int) {
        self.value = value
    }
}

let a = MyNumber(value:3)
let b = MyNumber(value:5)

infix operator ^-^ { }

func ^-^(lhs: MyNumber, rhs: MyNumber) -> MyNumber{
    return MyNumber(value: lhs.value + rhs.value)
}

// 結果は8
let c = a ^-^ b

infix operator ** { }

func **(lhs: Double, rhs: Double) -> Double {
    return pow(lhs, rhs)
}

// 結果は25
let d = 5.0 ** 2.0


使えるのは以下のものだけのようですね
/ = - + * % < > ! & | ^ . ~
