For loop Swift中的For循环

突然，我在苹果的文档中了解到的for循环结构停止工作，它显示了一个错误：预期声明。谁能告诉我新的语法是什么

let CirclePoints = 84

var circlePoint = 0

for circlePoint in 0..<CirclePoints {

}

let CirclePoints=84
var circlePoint=0
对于0..中的circlePoint，正如其他人所说，您的代码本身运行良好。如果您得到了错误预期声明，您可能在类主体中编写了如下代码：

class myClass{
let CirclePoints = 84

var circlePoint = 0

for circlePoint in 0..<CirclePoints {

}

}

class-myClass{
设CirclePoints=84
var circlePoint=0
对于0中的circlePoint..请定义“未工作”。给出一个错误：Expected declarationthis对我有效，就像@NoahWitherspoon说的，你需要说出“未工作”的意思。我刚才说。它给出一个错误：Expected declarationthis code在游乐场吗？你的文件中还有什么其他代码？
class myClass{
let CirclePoints = 84

var circlePoint = 0

for circlePoint in 0..<CirclePoints {

}

}

class myClass{
    let CirclePoints = 84
    var circlePoint = 0

    init(){
        for circlePoint in 0..<CirclePoints {

        }
    }
}
