# incomingServiceUpdatePush(channelManager:channelUUID:pushPayload:isHighPriority:remainingHighPriorityBudget:completion:) Extracts the service update data from the notification’s payload to perform the relevant task for that data. ``` optional func incomingServiceUpdatePush(channelManager: PTChannelManager, channelUUID: UUID, pushPayload: [String : Any], isHighPriority: Bool, remainingHighPriorityBudget: Int, completion: @escaping @Sendable () -> Void) ``` ``` optional func incomingServiceUpdatePush(channelManager: PTChannelManager, channelUUID: UUID, pushPayload: [String : Any], isHighPriority: Bool, remainingHighPriorityBudget: Int) async ``` ## Parameters `channelManager` The channel manager. `channelUUID` The channel identifier. `pushPayload` The push payload metadata. `isHighPriority` A flag indicating if this notification is a high priority. `remainingHighPriorityBudget` Monitors the number of remaining high-priority push notifications available to your app. Use low-priority push notifications (priority <= 5) whenever possible, as they aren’t subject to a budget limit. `completion` Execute to inform the Push to Talk framework you’ve finished your task. ## Discussion > Important: > You can call this method from synchronous code using a completion handler, as shown on this page, or you can call it as an asynchronous method that has the following declaration: > > ```swift > optional func incomingServiceUpdatePush(channelManager: PTChannelManager, channelUUID: UUID, pushPayload: [String : Any], isHighPriority: Bool, remainingHighPriorityBudget: Int) async > ``` > > For information about concurrency and asynchronous code in Swift, see . --- Copyright © 2026 Apple Inc.
