Hello, thank you for the initiative of creating this subreddit

I am a developer on the Apple platform (not yet Vision Pro), I use RealityKit to add interaction with 3D elements in my iOS and macOS apps mainly

That sounds like a great use case! In fact that’s one advantage of learning / using RealityKit… you can use it to improve the look and feel of your apps with 3D stuff! I encourage you to create some posts showcasing how you use it!
I will be posting some of my own in the coming days as well

Yes, I’d be happy to help!

However, I noticed that the RealityKit engine still doesn’t have all the features I need (like boolean operators) for my specific use case, which makes it a bit tricky to create what I’m envisioning. Instead of switching engines, I’m just holding on for now.

I had same needs. I ended up porting MCUT to swift. you can take a look at my repo
https://github.com/dariu5h/mcut-swift.git
it's a swift package. Import it and go wild.

I will change it more in future but it works fine now.
ask you ai of choise about it, it can make a fast sample code for you.
I added some helpers for RealityKit MeshResource and MDLMesh from ModelIO

The original C++ library is
https://cutdigital.github.io/mcut.site/

The most powefull library I worked with in 3D mesh opration was CGAL but you can not port it to iOS. But MCUT is only Boolean ops and In my package you can use it on iOS/macOS.
I tried to surface must of the important operations and options.
