我发生了崩溃EXC_BREAKPOINT 0x000000010097e11c
我的领导一直说这是一个参考周期。我不确定参考周期如何导致崩溃，因为它只会导致内存泄漏。
我认为它是一个僵尸对象，是一个对象不存在的内存泄漏。 （https://stackoverflow.com/a/50514660/1898829）
它在这样的行上崩溃
if model.object.array.isEmpty, let polyline = model.object.polyline {
模型不能为空
对象被声明为隐式展开的可选
数组不能为零
折线是带有问号（？）的可选声明
我无法重现崩溃，即使打开了僵尸对象，我也无法重现任何东西
这是崩溃日志

根据此https://stackoverflow.com/a/42823867/1898829 差额是由
引起的EXC_BREAKPOINT总是通过执行某种陷阱指令（*）来触发的，并且异常直接传递给执行陷阱指令的线程。因此，如果您看到崩溃报告说该堆栈中的该线程获得了EXC_BREAKPOINT，则意味着该线程确实对执行陷阱指令的操作有用。
并且进行谷歌搜索确实会保留周期，导致崩溃迅速不会产生任何好的来源。
我的问题是保留周期会导致崩溃吗，并且会导致EXC_BREAKPOINT崩溃
如果您能告诉我如何解决崩溃问题，奖励积分
