Unable to import Apple.Core into Unity due to the lack of VisionOS build support

Problem statement:
Hi, we encountered a blocker issue when we tried to install the Apple.Core package into our Unity project.
The error message says: Platform name 'VisionOS' not supported.

Details:
We carefully followed the steps described in the repo's quick start guide and created the .tgz files for the Apple.Core and Apple.GameKit plugins. Then we tried to import the Apple.Core and encountered the error mentioned above.
After some research we figured out that the problem was that VisionOS was not a supported build platform in our currently used Unity version (2021.3.45f2). Upgrading Unity to 2022.3 or latter is not an option for us due to known issues and time constraints. So we decided to try to exclude the VisionOS platform requirement from the Apple.Core build by using various options when generating the .tgz files as our project had nothing to do with VisionOS. Unfortunately we could not get rid of this issue.

Could you please provide us with a recommended python build statement or a helping advice on how to import Apple.Core into Unity if the Unity version does not support the VisionOS build platform?

We would greatly appreciate your help! Thanks in advance!

I too am having this issue same exact issue. We are using 2021.3.45f2 but after compiling and attempting to incorporate the plugin I receive the "VisionOS not supported" error within Unity.

The documentation is unclear as to which Unity version is required as it is not mentioned in the readme. The only place I see a version mentioned is in BuildScript documentation which mentions "2020.3.33f1". When building the plugin it does output "Project version: 2022.3.62f2" so Its that supposed to be the minimum version?

Thanks for any assistance!

From my understanding Unity support for PolySpatial requires version 2022.3 for support. I think visionOS support wasn't even talked about til WWDC 2023. If you need to support visionOS your best bet is to upgrade to 2022.3 LTS.

Hi,

Let me add some clarification:

The target build platform is iOS in our project. We don't intend to build to VisionOS at all.
However, when we try to import the Apple.Core plugin into our 2021.3.45f2 project Unity drops the following error:
"Platform name 'VisionOS' not supported."
This is true, this version does not even have VisionOS in the build platform list, but that should not block us from moving forward with iOS development.

In brief, this means that anybody who wants to import Apple.Core into his or her Unity project they just can't do that unless they have a Unity version of 2022.3 or newer regardless of their actual target platform.

I hope this helps.
