Has anyone else created a macOS SwiftUI app that uses a Table with a largish (~1000) number of entries? My app works OK at about 100 entries, but slows down as the number of entries increase. How slow? An instrumented test with 1219 entries shows a Hang of over 13 seconds from simply clicking/selecting an item in the table.
Instruments says the time is mostly spent in _CFRUNLOOP_IS_CALLING_OUT_TO_AN_OBSERVER_CALLBACK_FUNCTION. Digging deeper I see AG::Subgraph::update(unsigned int) and descendants account for about half of the hang time.
My app is using @Observable on macOS 14 and is being tested on an M2 Max Studio.
There are other reported hangs. All seem to be in Swift/SwiftUI code.
