如何解决未从Xcode启动时我的应用程序崩溃
在有无Xcode的情况下，直到今天运行良好。但是后来我将该设备升级到iOS 14.2 beta和Xcode 12.1，以测试一些功能。然后，我使用Xcode运行了该应用程序而没有问题，但是当我尝试在不附加Xcode的情况下运行该应用程序时，它便崩溃了。
我猜我的任何第三方库都可能与即将到来的iOS 14.2不兼容？但是那我怎么找到哪一个呢？
如果仅在应用程序未调试时发生该怎么办？
谢谢。
编辑：我能够使用Xcode检索此崩溃日志：

解决方法
错误消息告诉您，“进程启动看门狗越界：用尽20.00秒的实际（墙上时钟）时间余量”。您的应用启动时间过长。
从Xcode启动时不会发生这种情况的原因是在这种情况下看门狗被关闭了。但是，即使从Xcode启动，仍需要花费很长时间！
花费这么长时间的原因是您误解了如何发射。在启动期间（在主线程上）不要执行任务。在启动过程中，您要做的工作就是摆脱障碍，让设备启动该应用并使其运行。在启动过程中最好的事情就是什么都没有。退后一步。
如果您要执行耗时的任务，请稍后再在后台线程上执行。
