@Injected Properties Used in Sendable Situations Throw Concurrency Errors in Swift 6.3 (Xcode 26.4)

[Christopher-A]

Given this example, with StateMachine being Sendable,

@Injected(\.applicationStateMachine) var stateMachine

Task {
    await stateMachine.processEvent(event)
}

We get compiler errors (oddly only when building for device).
Task-isolated '_stateMachine' is captured by a nonisolated closure. nonisolated uses in closure may race against later nonisolated uses

However, we have found the following does not produce the error:

let stateMachine = Container.shared.applicationStateMachine.resolve()

There are known bugs, unfortunately, when using property wrappers with nonisolated types.

Note in Factory 3.0 (in develop), one can also do the following...

let stateMachine = dependency(\.applicationStateMachine)
