问题描述
我正在尝试调试我的应用程序的界面，并在启动时立即崩溃：
I'm trying to debug my app's interface and immediately as it launches it crashes with:
libc++abi.dylib: terminating with uncaught exception of type NSException
当我输入 bt 在调试窗格中

有没有一种方法，我可以得到比这更有用的信息来解决我的问题。我已经尝试了页面上的所有内容。
Is there a way I can get more useful information than this to solve my issue. I have already tried everything on this page.
有关如何调试Interface Builder文档的任何提示？
Any tips on how to debug Interface Builder documents?
推荐答案
事实证明，我有一个无法识别的选择器被发送到实例0xABC123 异常被抛出。我只是发现了这个，因为我使用了内联闭包：
It turns out that I had an unrecognized selector sent to instance 0xABC123 exception being thrown. I only discovered this because I used the inline closure:
NSSetUncaughtExceptionHandler { exception in
print(exception)
print(exception.callStackSymbols)
}
在我的申请结束时（_：我的AppDelegate中的didFinishLaunchingWithOptions :)方法。由于某种原因，符号任何异常断点都没有为我提供相同数量的细节。
at the end of my application(_:didFinishLaunchingWithOptions:) method in my AppDelegate. For some reason the symbolic any exception breakpoint wasn't providing me with the same amount of detail.
