Mute All Participants - iOS

If you are the host or moderator of a video conference, you may want to mute all the participants at once. This can be useful in various scenarios, such as when you want to deliver a presentation or when there is background noise that is causing distractions.

• To achieve this, you have to iterate over the list of participants from the Room class and call disableMic method from Participant class.
• room.participants holds the remote participants. disableMic() is async throws, so call it with try await inside a Task. Catch the error for each participant, so that one failure does not stop the rest.

Swift

extension RoomViewController {
    //Button when tapped will turn off mic of all participants
    @IBAction func muteAllButtonTapped(_ sender: Any) {
        guard let participants = room?.participants.values else { return }
        Task {
            for participant in participants {
                do {
                    try await participant.disableMic()
                } catch {
                    print("Could not mute \(participant.displayName): \(error)")
                }
            }
        }
    }
}

note

The participant who mutes other participants needs the allow_mod permission in their token. To know more about permissions visit here.
