Decrement index in a loop after Swift C-style loops deprecated

Question

How would you express a decrementing indexed loop in Swift 3.0, where the syntax below is not valid any more?

for var index = 10 ; index > 0; index-=1{
           


        

Answer 1

If you still want to use this C-style loop, here is what you need:

let x = 10

infix operator ..> { associativity left }
func ..>(left: Int, right: Int) -> StrideTo {
    return stride(from: left, to: right, by: -1)
}

for i in x..>0 {
    print(i)
}
