我们遇到了几起涉及MapKit的奇怪崩溃，特别是mapView.setRegion(_ region:, animated:)，保存的崩溃日志很奇怪，而且毫无帮助。它们似乎引用了内存位置，而不是代码行(异常回溯行4、5和线程0行7、13、14(。值得注意的是，从.xccrashpoint文件中删除了DSYM，即使调试信息与DSYM一起设置为DWARF。.xccrashpoint文件未在xCode中打开。请注意，崩溃日志来自iPhone X设备，因为特定的测试人员正在经历崩溃，我无法复制它。有人能帮我理解这些崩溃日志吗，或者给我一个最新的方法来理解它们吗？

谢谢！
我在.xcrashpoint包中找错了文件夹。有一个标记为"本地符号化"的子文件夹，其中有一个符号化的崩溃文件。带有符号化错误日志的子文件夹在此突出显示
