while debugging this for some time already, i observed that the leaks happen during the init of the actor, and even without any actor at all, as soon as i try to create a separate modelContext! seems like SwiftData cannot deal with two separate modelContext without leaking memory.

@FiratSirin no, besides the fact that those leaks are just visible inside the Xcode instruments, my app works just fine. those leaks do not seem to cause any problems (yet) i talked to apple about this issue during a wwdc24 labs session, and apple told me to open a bug report for this.. It should be fixed with iOS18. So i created a bug report with ID: FB13844786 for that topic
