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

how express decrementing indexed loop in swift 3.0, syntax below not valid more?

for var index = 10 ; index > 0; index-=1{    print(index) }  // 10 9 8 7 6 5 4 3 2 1 

here easier (and more swifty) approach.

for in (0 ..< 5).reversed() {     print(i) // 4,3,2,1,0 }  let array = ["a", "b", "c", "d", "e"] element in array.reversed() {     print(element) // e,d,c,b,a }  array.reversed().foreach { print($0) } // e,d,c,b,a  print(array(array.reversed())) // e,d,c,b,a
