适用于iOS v的BlackBerry Dynamics SDK。8.1.0.37和Firebase analytics使iOS 14上的应用程序崩溃

我们已经将BlackBerry Dynamics SDK集成到我们的iOS应用程序中，该应用程序也使用Firebase analytics。在运行iOS 12/13的设备上一切正常，但在运行iOS 14的设备上，初始化Firebase时应用程序崩溃

黑莓授权进行顺利，一旦用户获得授权，则会执行初始化Firebase的代码，并发生崩溃

BlackBerry Dynamics SDK版本为8.1.0.37，我们使用的是动态库而不是静态库

BlackBerry Dynamics文档说：

需要SDK版本8.1才能支持iOS上的FirebaseCore应用程序 14FirebaseCore与iOS 14上的SDK版本8.0或更低版本不兼容。如果未使用FirebaseCore吊舱，则应将其拆除 通过应用程序

以下是调用堆栈：

有人知道有没有办法解决这个问题吗？

在这种情况下，动态库和静态库应该是相同的。建议联系BlackBerry支持团队，调查问题是否仍然存在。

我们发现，只有当MobileIron的AppConnect SDK也链接到应用程序时，才会发生崩溃

因此，我们能够通过从应用程序的BlackBerry Dynamics版本中删除AppConnect SDK来解决这个问题
