我不时在应用程序启动时遇到崩溃，这并没有出现在 Crashlytics 中，但我设法获得了一份 .crash 报告并针对 .dsym 进行了符号化。这就是我得到的：

所以它似乎在调用时崩溃了CLSBetaController showBetaAlertForUpdate，我不知道它是什么，但经过一点浏览后，它似乎来自 Crashlytics 或 Twitter。
我确实有这些依赖项：
pod 'Fabric', '~> 1.10.2'
pod 'Crashlytics', '~> 3.14.0'
pod 'TwitterKit', '<3.3.0'
pod 'TwitterCore', '<3.1.0'
我不完全确定这是否是由这些引起的，我想知道是否应该有同样的问题:)
