Swift 정리 : 함수로부터 여러개의 결과 반환하기

func converter(length: Float) -> (yards: Float, centimeters: Float, meters: Float) {

let yards = length * 0.0277778

let centimeters = length * 2.54

let meters = length * 0.0254

return (yards, centimeters, meters)

}

var lengthTuple = converter(length:100)

print(lengthTuple) //(yards: 2.77778, centimeters: 254.0, meters: 2.54)

print(lengthTuple.yards) //2.77778

print(lengthTuple.centimeters) //254.0

print(lengthTuple.meters) //2.54
