Use BitArray in ObservationState

[tkunst891]

I have a feature which uses a BitArray (from Swift Collections) as a property in its State. How could I extend BitArray to make the individual bits observable? Currently change of any bit is updating all views which observe this property, even if the views access only one bit.

Hi @tkunst891, it most likely is a matter of implementing an overload of _$isIdentityEqual that is tuned specifically for bit arrays. We can see all the overloads we have here.

If that doesn't help then perhaps you can provide us with a simple project that reproduces the problem you are seeing. I'm not super familiar with bit arrays, and so would need a project to play around with to see what is going on.
