possible false positive with for_where (SwiftLint 0.17.0)

I got this code to find the previous item of an item which satisfies a condition:

func keyInputLeftArrow(_ keyInput: UIKeyInput) {
    var previousItem: CodeSelectTextField? = nil
    for item in codeInput.subviews as! [CodeSelectTextField] {
        if item.isFirstResponder {
            previousItem?.becomeFirstResponder()
            return
        }
        previousItem = item
    }
}

I'm not sure it can be rewritten using where. Maybe the SwiftLint warning shouldn't trigger when there are statements after the if (like previousItem = item in my example).
