iOS应用在发行中崩溃，但在开发中没有崩溃，并且Swift符号未解决 [英] iOS app crashing in release but not in development and Swift symbols are not resolved

问题描述

我的应用程序在开发中运行良好，但是切换到生产/AdHoc版本时，它在过渡到我的应用程序流的第三个UIViewController时崩溃.

My app is working perfectly fine in development but switching to production / AdHoc release it crashes on the transition to the third UIViewController of my application flow.

在版本之间应该没有任何区别.我已经从设备"窗口中检索了日志:

Between the build there shouldn't be any difference. I have retrieved the log from the Devices window:

困扰我的是什么

1. 我正在工作的环境之间显然存在矛盾.
2. MYAPP的调用似乎未链接到任何组件/方法调用.我正在使用Swift，也许确实会导致解析符号的问题.这可能是有道理的，因为PromiseKit调用也未解决.
3. 我不知道如何调试它，甚至也不知道如何将日志放到任何地方(因为我不知道如何获取它们).

欢迎任何帮助！

推荐答案

在 Build settings 中，尝试更改 Swift编译器-> 优化级别-> 释放至 None .仍然存在一个错误，即当启用优化时，有时编译器会弄乱闭包.也许这就是你正在发生的事情.

In Build settings, try changing Swift compiler -> Optimization Level -> Release to None. There's still a bug where sometimes the compiler messes up closures when optimizations are on. Maybe that's what's happening to you.
