【问题描述】：

我有这段代码在 xcode6 上运行良好，升级到 xcode7 后出现以下错误

var levels:[(
                level: Int,
                activeButtons: [UIButton],
                numberOfButtons: Int,
                timer: [Int],
                blinks: [Int],
                score: [Int],
                subIndex: Int,
                image: String,
                bunce : Int,
                speed: Double

    )] = []
levels.append(level:1, activeButtons:[], numberOfButtons:2, timer:[0,10,8,5],blinks:[0,2,3,4], score:[0,100,150,200], subIndex: 0, image: "blue", bunce: 150, speed:0.6)

我得到的错误是

不能使用类型为 '(level: Int, activeButtons: [UIButton], numberOfButtons: Int, timer: [Int], blinks: [Int], score: [Int], subIndex: Int, image: String, bnce: Int, speed: Double)' 1. 需要一个“（元素）”类型的参数列表

【问题讨论】：

制作一个结构体。请...

【参考方案1】：

您要添加的元素周围需要另一个大括号...

    var levels:[(
    level: Int,
    activeButtons: [UIButton],
    numberOfButtons: Int,
    timer: [Int],
    blinks: [Int],
    score: [Int],
    subIndex: Int,
    image: String,
    bunce : Int,
    speed: Double


    )] = []


    levels.append((level:1, activeButtons:[], numberOfButtons:2, timer:[0,10,8,5],blinks:[0,2,3,4], score:[0,100,150,200], subIndex: 0, image: "blue", bunce: 150, speed:0.6))

谢谢，解决了这个问题。为什么升级到 xcode 7 后我需要额外的大括号？
