  • VoIP apps have a specific background mode. You can't run a general task, like an MQTT service, in the background. iOS devices are not general purpose computers; they are mobile devices. If you want to receive messages then it would be better to have a server somewhere that subscribes to the required topic and sends a push notification to the iOS device. – Paulw11 Mar 30 '17 at 08:50

  • @ReevanshiGarg, when there are messages pending in the MQTT channel, post a silent push notification (APNS) to the device upon which you can initiate a background task for a limited time to pull the required data. – Preson Mar 30 '17 at 14:46
