# messages(of:) Returns the asynchronous sequence of messages that contain a generic data object. ``` final func messages(of type: Data.Type) -> GroupSessionMessenger.Messages ``` ## Parameters `type` The type of the class. Specify `Data.self`. ## Discussion Call this method to receive the messages that other participants send to the group. This method returns a [`GroupSessionMessenger.Messages`](/documentation/GroupActivities/GroupSessionMessenger/Messages) structure, which conforms to the `AsyncSequence` protocol. This sequence contains all, some, or none of the messages sent over time. You retrieve messages by iterating over them using an asynchronous `for`-`in` loop, as shown in the following example: ``` let sessionMessenger = GroupSessionMessenger(session: groupSession) async { for await dataMessage in sessionMessenger.messages(of: Data.self) { self.processDataMessage(dataMessage) } } ``` --- Copyright © 2026 Apple Inc.
