我按照此处的说明使用 Reality Composer 应用程序记录 ARKit mov 会话，但是当我加载 Xcode 并使用 ARKit 应用程序运行时，该应用程序显示黑屏并显示错误：该应用程序在没有 .mov 文件的情况下运行良好

实际上，在 Xcode 12 中，当使用 Reality Composer 的会话元数据为记录的 HEVC 文件激活重放功能时，存在构建问题。现在，在 Xcode 13.2 中，所有问题都消失了——一切正常，没有黑屏。

然而，唯一的问题是从记录的 AR Session 中解密元数据的速度非常慢。将 40 秒视频的元数据（ARWorldMap、平面、锚点等）上传并应用到 Xcode 项目中花了将近 7 分钟。

附言

我在 iPhone X 上的 Reality Composer 1.5.2 中录制了 iOS 15.2 中的会话。
