[英]Set a UIViewController inside a switch/case statement using Swift
[英]Using `case` with range in `switch` statement in Swift
我是 swift 的新手,並在 Swift Playgrounds 中進行了一些測試。 嘗試使用switch
,但它不起作用。 有人能幫我嗎?
func loveCal() {
let loveScore = Int.random(in: 0...100)
switch loveScore {
case 80...100:
print("You love eachother like Kanye loves Kanye")
case 40...80:
print("You go together like coke and mentos")
case 0...40:
print("You'll be forever alone")
}
}
loveCal()
您所缺少的只是default
情況:
// ...
case 0...40:
print("You'll be forever alone")
default:
print("This should never happen")
