Swift 3.0 error with C-style for loop

Question

I converted my project to Swift 3.0 and I get this error at the

for

line. Please see the error image below. After I converted it gave me a C-style error.

func removeButton(_ aButton: UIButton) {

    var iteration = 0

    var iteratingButton: UIButton? = nil

    for( ; iteration<buttonsArray.count; iteration += 1) {

        iteratingButton = buttonsArray[iteration]

        if(iteratingButton == aButton) {

            break

        } else {

            iteratingButton = nil

        }

    }

    if(iteratingButton != nil) {

        buttonsArray.remove(at: iteration)

        iteratingButton!.removeTarget(self, action: #selector(SSRadioButtonsController.pressed(_:)), for: UIControlEvents.touchUpInside)

        if currentSelectedButton == iteratingButton {

            currentSelectedButton = nil

        }

    }

}

It's a clear error, Swift 3 does NOT support the c-style for loop.

Instead, you should:

    for iteration in 0 ..< buttonsArray.count {
        iteratingButton = buttonsArray[iteration]
        if(iteratingButton == aButton) {
            break
        } else {
            iteratingButton = nil
        }
    }

You should check Apple's Documentation.
