Modifying state during view update

[ianthetechie]

There appears to be an issue with modifying state during view update in one code path. The issue is that parent.camera is a @Binding, so we're mutating state up the chain.

In years past, I would have just reached for dispatch_async, even though it feels a bit dirty. This guy who claims to work at Apple also seems to agree that it's an acceptable solution as of 2021, but Swift 6 is still trying to figure out a new concurrency story which may complicate things. Does anyone have a better idea?

Looking at MapKit. Pretty much every type is wrapped in @MainActor @preconcurrency, including their Map view, annotations, etc. Given this library is also just UI, a solution like that seems to make sense here as well. Anything you can think of that needs to be allowed to run on another thread?
