Extensions:

    import Foundation
    extension NSDate {
        func xDays(x:Int) -> NSDate {
            return NSCalendar.currentCalendar().dateByAddingUnit(.CalendarUnitDay, value: x, toDate: self, options: nil)!
        }
        var day:            Int { return NSCalendar.currentCalendar().components(NSCalendarUnit.CalendarUnitDay,           fromDate: self).day           }
        var month:          Int { return NSCalendar.currentCalendar().components(NSCalendarUnit.CalendarUnitMonth,         fromDate: self).month         }
        var year:           Int { return NSCalendar.currentCalendar().components(NSCalendarUnit.CalendarUnitYear,          fromDate: self).year          }

Run multiple notifications through a function in Swift in Xcode?

It's because the same identifier

 let request = UNNotificationRequest(identifier: "testIdentifier", content: content, trigger: trigger)

so change it for every scheduled notification

How to implement multiple local notifications on specific day of weeks at different times in swift

UILocalNotification is deprecated in iOS 10. Use UNNotificationRequest instead,

import UIKit
import UserNotifications

class ViewController: UIViewController, UNUserNotificationCenterDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()

        //requesting for authorization
        UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge], completionHandler: {didAllow, error in
                if error == nil {
                    self.addMultipleLocalNotification()
            }
        })
    }

    func addMultipleLocalNotification(){
        //creating the notification content
        let content = UNMutableNotificationContent()

        //adding title, subtitle, body and badge
        content.title = "Notification title "
        content.subtitle = "Notification sub-title "
        content.body = "We are learning about iOS Local Notification"
        content.badge = 1

        var sundayDate = DateComponents()
        sundayDate.weekday = 0 // which is Sunday
        sundayDate.hour = 10
        sundayDate.minute = 00

        var wedDate = DateComponents()
        wedDate.weekday = 3 // which is wednesday
        wedDate.hour = 18
        wedDate.minute = 00

        let trigger = UNCalendarNotificationTrigger(dateMatching: sundayDate, repeats: true)
         let trigger1 = UNCalendarNotificationTrigger(dateMatching: wedDate, repeats: true)
        let request = UNNotificationRequest(identifier: "notificationName", content: content, trigger: trigger)
        let request2 = UNNotificationRequest(identifier: "notificationName2", content: content, trigger: trigger1)

        UNUserNotificationCenter.current().delegate = self

        //adding the notification to notification center
        UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)
           UNUserNotificationCenter.current().add(request2, withCompletionHandler: nil)

        UNUserNotificationCenter.current().getPendingNotificationRequests(
        completionHandler: { (notficiations) in
            for localNotification in notficiations {
                print(localNotification)
            }
        })
    }

    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {

        //displaying the ios local notification when app is in foreground
        completionHandler([.alert, .badge, .sound])
    }
}

iOS local notification base on day, time frame and number of times?

If you want to schedule multiple notifications, you need to create multiple notification triggers and register them.

something like:

// Simple extension if you have to create multiple of the same object
extension DateComponents {
   static func triggerFor(hour: Int, minute: Int) -> DateComponents {
      var component = DateComponents()
      component.calendar = Calendar.current
      component.hour = hour
      component.minute = minute
      component.weekday = 1
      return component
   }
}

// Add each trigger into an array with the correct date component
let triggers = [
    UNCalendarNotificationTrigger(dateMatching: DateComponents.triggerFor(hour: 1, minute: 0), repeats: true),
    UNCalendarNotificationTrigger(dateMatching: DateComponents.triggerFor(hour: 2, minute: 0), repeats: true),
    UNCalendarNotificationTrigger(dateMatching: DateComponents.triggerFor(hour: 3, minute: 0), repeats: true),
    UNCalendarNotificationTrigger(dateMatching: DateComponents.triggerFor(hour: 4, minute: 0), repeats: true),
    UNCalendarNotificationTrigger(dateMatching: DateComponents.triggerFor(hour: 5, minute: 0), repeats: true)
]

// Iterate through the array and register the notification with the system
for trigger in triggers {
    // Create the content of the notification
    let content = UNMutableNotificationContent()
    content.title = "My Notification Title"
    content.body = "Body of Notification"

    // Create the request
    let uuidString = UUID().uuidString
    let request = UNNotificationRequest(identifier: uuidString, 
                content: content, trigger: trigger)

    // Schedule the request with the system.
    let notificationCenter = UNUserNotificationCenter.current()
    notificationCenter.add(request) { (error) in
       if error != nil {
          // Handle any errors.
       }
    }
}
