在 ARView 中放置对象时，ARKit RealityKit 会在运行时发出警告

如何解决在 ARView 中放置对象时，ARKit RealityKit 会在运行时发出警告

我在运行时在 ARView 中点击加载模型时收到以下警告：警告（辅助线程）：在 sdf/path.cpp 的第 859 行的 AppendProperty -- 只能附加一个属性 'preliminary:anchoring:type ' 到主要路径 (/) 警告（辅助线程）：在 sdf/path.cpp 的第 859 行的 AppendProperty 中 -- 只能将属性“触发器”附加到主路径 (/)

有人知道为什么我会收到此警告吗？所有逻辑都在我的 ViewController 中：
