Loading Entities from a file

Question

I created a .reality file which i exported from Reality Composer and added to the project.

The code:

class ViewController: UIViewController {

@IBOutlet var arView: ARView!

    override func viewDidLoad() {
        super.viewDidLoad()
    
        if let anchor = try? Entity.loadAnchor(named: "ARAnchorTestFile") {
             arView.scene.addAnchor(anchor)
        }
    }
}

On devices with iOS version 13.5 or higher the app crash when the anchoring is triggered and the 3D model should be displayed.

The error:

Thread 1: EXC_BAD_ACCESS (code=1, address=0x40)

The entire project has been uploaded to this repo: https://github.com/evjand/ARAnchorTest

UPDATE: After filing a bug repport to Apple it seems like they have fixed it in the iOS 14 beta.

Answer 1

Seems there's a bug when reading .reality file. Use .rcproject format instead. It works.

if let anchor = try? Entity.loadAnchor(named: "AR") {            
    arView.scene.addAnchor(anchor)
    print(anchor)
}
