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

Hi @jesus-mg-ios, thank you for raising this issue. Could you please provide more details on it?

[jesus-mg-ios]

Sure, imagine that you got a variable var serverTimestamp: ServerTimestamp<Date> to decode a response using Firestore, then ServerTimestamp is marked as Non Sendable ...

So it would be nice, that if Date, (that it is ) is sendable, then ServerTimestamp could be Sendable

Something like this extension ServerTimestamp: Sendable where T: Sendable {} Because in this case ServerTimestamp can be Sendable if T it is. @milaGGL

Hi @jesus-mg-ios, improving Sendable conformance in the SDK is certainly on our radar, but it is deprioritized for now. I've added your request to our backlog so we can consider it for future development. Googlers please see b/378477431.

Thank you again for bringing this to our attention. I'll close the issue for now and will update it if there are any changes.

Reopening since we are investigating better Swift Concurrency support across Firebase and we can consider this request in that effort.

@jesus-mg-ios, thanks again for the report! This will go out in the next release. I'll be continuing to improve the Swift 6 experience in future releases (e.g. #14163, etc.).
