For backwards gives an error in Swift 3. How do I fix it?

  • 772

I updated the xCode and I am full of warning, almost all of them have been solved, but this one is missing

for var i:Int = row-1; i >= 0; i -= 1

It throws me the following warning:

C-style for statement is deprecated and will be removed in a future version of Swift

    That kind of forwill be deprecated in Swift 3.0. The equivalent function would be the following:

    for i in (0...row - 1).reverse() {

}

    or failing that and probably more correct:

    for i in (0..<row).reverse() {

}
