swift3 - How to cancel particular recurring local notification and reschedule it for next week in iOS 10(Swift) -

i have created different local notifications set weekdays , weekends repeat continuously

let trigger = uncalendarnotificationtrigger(datematching: triggerweekly, repeats: true) let content = unmutablenotificationcontent() content.body = "time_to_step_shapa".localized content.sound = unnotificationsound.default()  let request = unnotificationrequest(identifier: "\(notificationtype)-\(remindertype)-\(day)", content: content, trigger: trigger)  unusernotificationcenter.current().getnotificationsettings { (settings) in     if settings.authorizationstatus != .authorized {         print("local notifications not authorized user")     } } unusernotificationcenter.current().add(request) {(error) in     if error != nil {         print("error: \(error?.localizeddescription)")     } } 

and cancelling particular notification verifying notifications based on proper conditions , updating same notification next week.

if (type == notificationtype && notificationweekday == currentweekday) {     //cancelling local notification     app.cancellocalnotification(notif)      let firedate = self.getupdatednotification(currentdate: currentlocaldate!, firedate: notificationfiredate!)      hikecommonutils.setuplocalnotification(firedate, type: notificationtype, remindertype: remindertype) } 

and updating next fire date using

func getupdatednotification(currentdate: date, firedate : date) ->date {     let calendar = calendar.autoupdatingcurrent     let datecomponents = (calendar nscalendar).components(([.year, .month, .day]), from: currentdate)     let timecomponents = (calendar nscalendar).components(([.hour, .minute, .second]), from: firedate)     var datecomps = datecomponents()     datecomps.day = datecomponents.day! + 7     datecomps.month = datecomponents.month     datecomps.year = datecomponents.year     datecomps.hour = timecomponents.hour     datecomps.minute = timecomponents.minute     datecomps.second = timecomponents.second     let itemdate = calendar.date(from: datecomps)     return itemdate! } 

even after removing notification firing removed date because of repeat 'true'.

is there option adding start date in local notifications in ios 10?

thanks in advance!!

you can add logic nexttriggerdate()

func nexttriggerdate() 

the next date @ trigger conditions met.

use property find out when notification associated trigger next delivered.
