Unity Engine

Greetings,

We are able to build our game to the visionOS simulator, however when building to device, the app crashes immediately with the following error Symbol not found: _ar_device_anchor_create which is referenced in ARKit.

Any help pointing us in the right direction would be wonderful.

Thanks!

Hi there! Which version of com.unity.xr.visionos are you using?

It looks like 0.3.1 currently. With 2022.3.9f1 and XCode 15 beta 8

OK thanks. I’m going to see if I can replicate the issue with that version. That API should exist on visionOS beta 3, which is included in Xcode 15b8. I don’t think this would cause issues at build time, but is your device updated to visionOS beta 3?

Okay, we’re going to upgrade the visionOS kit to the beta 3 and try again. Thanks for the information. We’ll report back here if successful.

Hey, FYI I re-read your original message, and I originally missed the “app crashes” detail. If the app builds, and then crashes I’m pretty sure this would be fixed by updating the OS. My local test seems to be working.

Confirming we can run the app on device now. Thank you again for the quick response.

No problem! Glad you were able to work it out.
