swift - 编译发布时出现奇怪的错误？

Question

我的代码中的这一行是我的应用程序仅在发布构建时才不断崩溃的地方。

self.setup.monthByInt = [1:"一月", 2:"二月", 3:"三月", 4:"四月", 5:"五月", 6:"六月", 7 :"July", 8:"August", 9:"September", 10:"October", 11:"November", 12:"December"]

func updateMonthArrayForCircle(){
    self.setup.monthByYear = ["January":0, "February":0, "March":0, "April":0, "May":0, "June":0, "July":0, "August":0, "September":0, "October":0, "November":0, "December":0]
    self.setup.monthByInt = [1:"January", 2:"February", 3:"March", 4:"April", 5:"May", 6:"June", 7:"July", 8:"August", 9:"September", 10:"October", 11:"November", 12:"December"]
}

self.setup 引用一个结构，我在其中将具有相同值的原始数组存储在 [Int:String] 初始化对象中。

struct initialize {
    let largeFrame: CGRect = CGRect(x: 0, y: 0, width: 130, height: 130)
    let smallFrame: CGRect = CGRect(x: 15, y: 25, width: 100, height: 100)
    let screenSize: CGRect = UIScreen.main.bounds

    var month: [String] = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]
    var monthByYear: [String:Int] = ["January":0, "February":0, "March":0, "April":0, "May":0, "June":0, "July":0, "August":0, "September":0, "October":0, "November":0, "December":0]
    var monthPure: [String] = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]

    var monthByInt: [Int:String] = [1:"January", 2:"February", 3:"March", 4:"April", 5:"May", 6:"June", 7:"July", 8:"August", 9:"September", 10:"October", 11:"November", 12:"December"]
    var intByMonth: [String:Int] = ["January":1, "February":2, "March":3, "April":4, "May":5, "June":6, "July":7, "August":8, "September":9, "October":10, "November":11, "December":12]
    var monthIndex: Int = 7
}

代码在 Debug模式下运行良好。

好的，所以你的问题的原因是因为你正在使用转义闭包。该函数在调用完成处理程序之前返回。

解决方法如下:

sync(completionHandler: { [weak self] (success) -> Void in
    if success {
        self?.delegate?.amareUserDone()
    }
})
