I’ve enabled Xcode ‘strict concurrency checking’ and am now getting errors on the sample data model of a Post.

struct Post: Identifiable, Codable {
    @DocumentID var id: String?
    var title: String
    var content: String
    var timestamp: Date
}

func firebaseQuery(queries: [String], queryField: String) async throws -> [Post] {
        
   var results = [Post]()
        
   try await withThrowingTaskGroup(of: [Post].self) { group in
       for query in queries {
           group.addTask { [self] in
               return try await getPostsFromFirebase(query: query, queryField: queryField)
           }
        }
            
        for try await result in group {
           results.append(contentsOf: result)
        }
   }
        
   return results
}

Error "Type 'Post' does not conform to the 'Sendable' protocol"

Adding Sendable compliance to Post gives this error:

Stored property '_id' of 'Sendable'-conforming struct 'PostSendable' has non-sendable type 'DocumentID<String>'

How do I make Post comply to Sendable, or work with it not being Sendable?

Thanks
