We are seeing some memory leaks when adding ModelEntities to an anchor, pausing the ARSession and starting it again and adding ModelEntities again....We see memory growing in the re::SyncObject section. Does anyone have experience troubleshooting memory leaks that have happened in a similar way?
I’d recommend this year’s WWDC Xcode session, What's new in Xcode, for what’s new in debugging. And there have been many other excellent sessions over the years on debugging.
That said if you believe it may be RealityKit or another system framework responsible for leaking the entities we’d ask you to file a Feedback Item on http://feedbackassistant.apple.com if you haven’t done so already.
