Launching an iOS app on Vision Pro Simulator Error: Simulator device returned an error for the requested operation

Question

I have a iOS app which I'm trying to test on a Apple Vision Pro Simulator from XCode 15 Beta 2.

The app builds successfully, but I'm getting the following error when the app should launch on the simulator:

Simulator device returned an error for the requested operation.

System Information

macOS Version 13.4 (Build 22F66)
Xcode 15.0 (22181.22) (Build 15A5161b)
Timestamp: 2023-06-25T15:10:54+03:00

Cleaning the build folder and restarting XCode & the simulator does not seem to help.

Any suggestions on what else I could try are appreciated.

Answer 1

The reason I was getting this error was because of an Environment Variable.

I had to select my scheme, and select Edit Scheme. I have selected the Arguments tab, and under Environment Variables I had an empty variable:

As soon as I have unchecked the checkbox next to it, the problem has gone away.
