Steps to reproduce:

1. Unzip and open attached project.

2. Use Unity 2022.3.52f1 or 6000.0.25f1 to open the ARDemoScene scene.

3. In Build Settings, add current scene and switch platform to iOS. 

4. Build and Run. 

5. Do whatever you normally do in Xcode to deploy to your iOS device.

6. Scan your real world environment until you find a plane. 

7. Tap the plane several times to spawn a few objects. 

8. Tap an object to select it. 

9. Tap the trash can icon to delete the selected object. 

10. Tap another object to select it. 

Actual results: 

Your tap event does not select the object.  Instead, it might fall through to the plane and spawn another object. 

If you tap the object again then it will be selected.  But if you delete this object, then then next selection tap will be ignored... 

Expected results: 

Your tap should select the tapped object, making it highlight. 

Reproducible with versions: 

Unity 2022.3.52f1 and 6000.0.25f1. 

Not reproducible with versions: 

Unity 2021.3.45f1. 

Can’t test with versions: 

Tested on (OS): 

MacBook Pro - M1 Pro; MacOS 14.6.1

iPhone 13; iOS 17.3.1

Notes:

• This is a regression because it did not repro in 2021.3.  During earlier testing it might have been masked by other selection bugs.
• There is a separate tap bug on Android: XRIT-208.
