[FR]: Making Model Objects `Sendable`

[Blackjacx]

Description

Now as we convert our project to Swift Concurrency and Swift 6 we came across the warning Stored property 'snapshot' of 'Sendable'-conforming struct 'FirebaseUpdate' has non-sendable type 'DataSnapshot'; this is an error in the Swift 6 language mode in this object:

import FirebaseDatabase

struct FirebaseUpdate: Sendable {
    var snapshot: DataSnapshot
}

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

Therefore my question: Is ther 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.

Thanks, @Blackjacx, we are actively working on improving Swift 6 support across Firebase. Some of the changes can be done incrementally and some of the changes require a breaking change. I have not audited FirebaseDatabase yet, but will take a closer look.

@ncooke3, would it be possible to ensure ListenerRegistration also conforms to Sendable in this work?
