[FR]: Making ListenerRegistration Model Objects Sendable

Description

Now as we convert our project to Swift Concurrency and Swift 6 we came across the warning Capture of 'listener' with non-sendable type 'any ListenerRegistration' in a '@sendable' closure:

import FirebaseDatabase

func coolStream() -> AsyncStream<[Stuff]>{
        return AsyncStream { continuation in
            let collection: String = "cool"
            let db = Firestore.firestore()
            let listener = db.collection(collection)
                .addSnapshotListener(
                    listener: { snapshot, error in
                        guard let snapshot else {
                            return
                        }
                        let results: [Stuff] = snapshot.documents
                            .map({ try? $0.data(as: Stuff.self) })
                            .compactMap({ $0 })
                        continuation.yield(results)
                })
            
            continuation.onTermination = { _ in
                listener.remove() // <<<-- ERROR/WARNING Capture of 'listener' with non-sendable type 'any ListenerRegistration' in a '@Sendable' closure
            }
        }
    }

To silence this we could add @preconcurrency but we also loose sight of these warnings then.

Therefore my question: Is there a specific timeline for when this model object will become Sendable?

I tested with version 11.7.0 today and still get this.

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

We are continuously working on addressing Swift 6 warnings and errors across all of the SDKs. I'll take a look at addressing this particular warning.
