Trouble loading a reference object from Asset Catalog

Hi,

I'm trying to test object recognition using ARKit. I scanned a couple of objects using the Apple demo app, copied the .arobject files to my laptop.

I added them to my new project in Assets like shown in the image.

However, as I follow the tutorial to load these objects to use as reference objects, I run into an error.

        let configuration = ARWorldTrackingConfiguration()
        guard let referenceObjects = ARReferenceObject.referenceObjects(inGroupNamed: "Test", bundle: Bundle.main) else {
            
            let ro = ARReferenceObject.referenceObjects(inGroupNamed: "Test", bundle: nil);
            let ro1 = ARReferenceObject.referenceObjects(inGroupNamed: "Gallery", bundle: .main);
            fatalError("Resource not found")
        }

Here, we fail the guard statement and the ro and ro1 both are set to nil.

I created a new project with just this one statement and that fails too.

I'm using SwiftUI instead of UIKit if that makes a difference and am calling this in the makeUIView() function .

Any pointers to what I might be doing wrong here are appreciated.
