Local Notifications The big problem with APNS is that it requires you to run a server somewhere that interacts with APNS to push a notification to a device. For applications that already have a client-server architecture such as an IM client this is no big deal. There are also a number of third parties who can provide a cost efficient service for small scale users who do not want the trouble of running their own server. However for many applications this is still way too complicated. This blog helps us in triggering the notification at specific time which is being selected by user in date picker. For that you have to take textField and two buttons. And don,t forget to edit AppDelegate method. import  UserNotifications   func  application( _  application:  UIApplication , didFinishLaunchingWithOptions launchOptions: [ UIApplicationLaunchOptionsKey :  Any ]?) ->  Bool  {          le...

The Apple Push Notification Service (APNS) was released way back in iOS 3.0. That was only just over a year ago but given the pace of development in the mobile OS market that now seems like ancient history. APNS was a first tentative attempt by Apple to address the demand for background processes. It allows client applications to receive updates from a server without having to be running. Apple takes care of pushing the notification to the device and the user can then decide whether to launch the application or not.
