曾经尝试从Apple的App Review Department破译这些（已经符号化的）崩溃日志。他们声称我们的应用程序在12.1 iOS iPad设备上崩溃，但是我们已经在iPhone 5、6、7和8以及12.9英寸iPad（所有都运行iOS 12.1）上进行了测试，所有。
在查看这些日志时，我只能说也许是异常与我们使用AirPlay的应用程序有关，但我不确定。此外，失败的线程（线程25）还在该主题的其他讨论中引用了该流服务，其中一些在StackOverflow上找到。任何人都可以阐明这里可能发生的情况吗？
一些一般事实：
我们的应用程序是AR应用程序
在Unity 2018.2.14f1中创建
运行Vuforia 7.5.26
利用按需资源来处理一些应用程序大小问题
