Question

应用程序运行一段时间后，我收到一个SIGBART信号。我怀疑它与在后台运行的计时器有关。

这是我用来调用循环计时器的代码：

 Timer.scheduledTimer(timeInterval: 20 , target: self, selector: #selector(self.scheduledEventHandler), userInfo: nil, repeats: true)

这是处理程序：

@objc func scheduledEventHandler()
{
     print("got event")
}

最后，这是堆栈跟踪：

    thread #1, queue = 'com.apple.main-thread', stop reason = signal SIGABRT

    frame #19: 0x00007fff516dd145 libdyld.dylib`start + 1

*请注意，此任务在大多数情况下运行良好（很少崩溃）。

我会感谢任何建议，以便更好地了解此类崩溃的原因。
