直到我在手机上安装 iOS 12 测试版捕获深度数据之前工作正常，但现在我收到一个错误：
Error Domain=AVFoundationErrorDomain Code=-11800“操作无法完成” UserInfo={NSLocalizedFailureReason=发生未知错误（-16800），NSLocalizedDescription=操作无法完成，NSUnderlyingError=0x283094510 {Error Domain=NSOSStatusErrorDomain Code=- 16800 “（空）”}}
我不明白这个错误来自哪里。错误打印在if error照片输出部分。
