This package demonstrates some challenges in accessing MainActor bound properties. For example purposes, I'm using UIUserInterfaceIdiom, but it be any property that is @MainActor bound.
-
Example01 - shows how the naive approach forces
@MainActoronto all intializers, which is not something we always want or can do. -
Example02 - simply demonstrates that MainActor isolation is a compile time failure when struct concurrency checking is enabled
-
Example03 - demonstrates a one approach in not requiring
@MainActorfor the initializer. It has the unfortunate side-effect of requiring not being on the main thread. -
MainActorWoesTests - demonstrates how these examples might look at the call-site and in unit tests.
