I need your help for a project. I have 3 variables, one for the day , another for the month and last for the year. Like that :

var year = 2017 var month = 06 var day = 19

I want to send a notification even if the app is close when we are at the date of these variable, but i'm not really good with Calendar and Date. I just made this app for the moment.

let myNotification = Notification.Name(rawValue:"MyNotification")

override func viewDidLoad() {

    let nc = NotificationCenter.default
    nc.addObserver(forName:myNotification, object:nil, queue:nil, using:catchNotification)

override func viewDidAppear(_ animated: Bool) {
    let nc = NotificationCenter.default
            object: nil,
            userInfo:["message":"Hello there!", "date":Date()])

func catchNotification(notification:Notification) -> Void {
    print("Catch notification")

    guard let userInfo = notification.userInfo,
        let message  = userInfo["message"] as? String,
        let date     = userInfo["date"]    as? Date else {
            print("No userInfo found in notification")

    let alert = UIAlertController(title: "Notification!",
                                  message:"\(message) received at \(date)",
        preferredStyle: UIAlertControllerStyle.alert)
    alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.default, handler: nil))
    self.present(alert, animated: true, completion: nil)

Thank you in advance

You need to set up a local notification and use a UNCalendarNotificationTrigger to fire it at a specific date.

let dateComponents = DateComponents(year: year, month: month, day: day)
let yourFireDate = Calendar.current.date(from: dateComponents)
let content = UNMutableNotificationContent()
content.title = NSString.localizedUserNotificationString(forKey:
            "Your notification title", arguments: nil)
content.body = NSString.localizedUserNotificationString(forKey: "Your notification body", arguments: nil)
content.categoryIdentifier = "Your notification category"
content.sound = UNNotificationSound.default()
content.badge = 1

let dateComponents = Calendar.current.dateComponents(Set(arrayLiteral: Calendar.Component.year, Calendar.Component.month, Calendar.Component.day), from: yourFireDate)
let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: false)
let request = UNNotificationRequest(identifier: "Your notification identifier", content: content, trigger: trigger)
UNUserNotificationCenter.current().add(request, withCompletionHandler: { error in
        if let error = error {
            //handle error
        } else {
            //notification set up successfully

Launch a local notification at a specific time in iOS, Make the request early in your App life cycle such as in application:didFinishLaunchingWithOptions:. The first time your App requests authorization the system shows the user an alert, after that they can manage the permissions from settings: // Swift let options: UNAuthorizationOptions = [. alert, . The process for creating a local notification using Swift 3 for iOS 10, feels a lot simpler than previous versions. In this simple example, I barely touch on the capabilities of the new rich notifications you can create. I have created a GitHub repository with example code here.

In swift 3 - 4 use this.

  func scheduleLocal() {

        let dateComponents = DateComponents(year: 2019, month: 1, day: 17, hour: 10, minute: 20)
        let yourFireDate = Calendar.current.date(from: dateComponents)

        let notification = UILocalNotification()
        notification.fireDate = yourFireDate
        notification.alertBody = "Hey you! Yeah you! Swipe to unlock!"
        notification.alertAction = "be awesome!"
        notification.soundName = UILocalNotificationDefaultSoundName
        notification.userInfo = ["CustomField1": "w00t"]


Scheduling a Notification Locally from Your App, Create and schedule notifications from your app when you want to get the user's app could ask the system to display an alert when a particular task is finished.

Here is a way to add your Custom events to Calender.

let store = EKEventStore()
store.requestAccessToEntityType(.Event) {(granted, error) in
    if !granted { return }
    var event = EKEvent(eventStore: store)
    event.title = "Event"
    event.startDate = NSDate() //Event date
    event.endDate =    event.startDate.dateByAddingTimeInterval(60*60) //even duration ex.1hr
    event.calendar =     store.defaultCalendarForNewEvents
    do {
        try store.saveEvent(event, span: .ThisEvent, commit: true)
        self.savedEventId = event.eventIdentifier //save this id for future reference 
}     catch {
    // Display error
