我亲眼目睹了用户 iPad 的崩溃，奇怪的是，在崩溃之后，即使单击主页按钮，应用程序仍然锁定在应用程序的初始屏幕上。
如果我尝试符号化我自己项目中的任何条目，我会得到：
atos cannot load symbols for the file 3rdparty for architecture arm64.
我的应用程序或用户设备是否有问题我可以帮助他修复？
谢谢
这是我最好的猜测。来自 Apple 文档：
Trace Trap [EXC_BREAKPOINT // SIGTRAP]
Similar to an Abnormal Exit, this exception is intended to give an
attached debugger the chance to interrupt the process at a specific
point in its execution. You can trigger this exception from your own
code using the __builtin_trap() function. If no debugger is attached,
the process is terminated and a crash report is generated.
Swift code will terminate the program with this exception type if it
detects an unexpected condition at runtime such as:
- a non-optional type with a nil value
- a failed forced type conversion
Look at the Backtrace of the crashed thread to determine where the
unexpected condition was encountered. Additional information may have
also been logged to the device's console.
根据我的经验，我发现以上内容是正确的。当我对可选选项草率时（例如，使用 as! 强制转换或没有正确使用可选绑定），我经常遇到异步（网络 - 在我的例子中）操作的问题。
此外，为了符号化，您应该使用 AppStore 构建和 .dSYM 文件（iTunes Connect 提交的存档）。

问题是由于显示的 tableCell 内部崩溃所致。发生这种情况时，调试器通常非常讨厌。无论如何，我在 Xcode 中发现了一个我不知道的选项，用于查看来自其他设备的崩溃位置的中间代码符号。我发现它引用了我的 类 之一中显示的单元格，因此将我指向该错误。
