在Swift 2.2.1中替换C样式的for循环 [英] Replace c style for-loop in Swift 2.2.1

问题描述

这是我的应用程序中的循环:

This is the loop in my app:

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

}

在Swift 2.2.1中实现此循环的最佳方法是什么?

推荐答案

尝试一下:

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

这种滥用for循环语法的确切原因是它在Swift 2.2中被弃用.即使for语法可用，这仍然比可憎的语法更清楚

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
