code:

detailviewcontroller :

you should use uilocalnotification. use date , time create nsdate object , setup notification this:

let notification = uilocalnotification() notification.firedate = ... // add date here notification.alertbody = "alert alert alert!!!" uiapplication.sharedapplication().schedulelocalnotification(notification) 

handle notification in appdelegate overriding didreceivelocalnotification method:

func application(application: uiapplication, didreceivelocalnotification notification: uilocalnotification) {     println(notification.alertbody);  // "alert alert alert!!!" }
