Replace c style for-loop in Swift 2.2.1

Question

This is the loop in my app:

for var i = column - 1; i >= 0 && burgers[i, row]?.burgerType == burgerType;
        i -= 1, horzLength += 1 {

}

What would be the best way to implement this loop in Swift 2.2.1?

Do you mutate `i` or `horzLength` inside the loop body? – Qbyte May 03 '16 at 19:42 — Qbyte, May 03 '16 at 19:42

Try this:

var i = column - 1
while i >= 0 && burgers[i, row]?.burgerType == burgerType {
    i -= 1
    horzLength += 1
}

This sort of abuse of the for loop syntax was the exact reason it was deprecated in Swift 2.2. Even if a for syntax was available, this would still be more clear than that abomination
