Swift 3 Local notifications not firing - ios

Question

I have the following setup and no notification are firing at all.
Based on other similar questions on the stack, I've put in a unique identifier for each request and I've also added the body to the content.
I've got this function which requests permission from user.
func sendIntNotifications()
{
//1. Request permission from the user
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound], completionHandler:
{
(granted, error) in
if granted
{
print ("Notification access granted")
}
else
{
print(error?.localizedDescription)
}
UNUserNotificationCenter.current().delegate = self
})
// This function has a lot of other code that then calls this function to set multiple notifications :
for daysInt in outputWeekdays
{
scheduleActualNotification(hourInt: hourInt, minuteInt: minuteInt, dayInt: daysInt)
}
}
And these are the main function :
func scheduleActualNotification(hourInt hour: Int, minuteInt minute: Int, dayInt day: Int)
{
// 3.1 create date components for each day
var dateComponents = DateComponents()
dateComponents.hour = hour
dateComponents.minute = minute
dateComponents.day = day
//3.2 Create a calendar trigger for that day at that time
let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents,
repeats: true)
//3.3 Message content
let content = UNMutableNotificationContent()
content.title = "Test Title"
content.body = "Test body"
content.badge = 1
// 3.4 Create the actual notification
let request = UNNotificationRequest(identifier: "bob \(i+1)",
content: content,
trigger: trigger)
// 3.5 Add our notification to the notification center
UNUserNotificationCenter.current().add(request)
{
(error) in
if let error = error
{
print("Uh oh! We had an error: \(error)")
}
}
}
This function is to receive the notification when this app is open
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: #escaping (UNNotificationPresentationOptions) -> Void)
{
completionHandler([.alert, .sound]) //calls the completionHandler indicating that both the alert and the sound is to be presented to the user
}
There are no errors either lol!
Edit :
So from the user interface, I selected 2350 and Saturday and Sunday. I expect the notification to be sent at 2350 on both Saturday and Sunday.
I did print(daysInt). The first value of it is 1 and the second value of it is 7 which is just as expected. Secondly, I went into the function scheduleActualNotification and the values of hour was 23 and minute was 50, just as expected.
Thank you!

Answer 1

So after weeks of frustration, this is the solution :
Replace dateComponents.day = day with dateComponents.weekday = day. .day is for day of the month whereas .weekday is day of the week!
Also do not use dateComponents.year = 2017 as that caused the notifications not to fire.
The notifications work perfectly fine now!!

Calendar Unit Flags can help you :
var notificationTriggerCalendar : UNCalendarNotificationTrigger? = nil
if let fireDate = trigger.remindAt {
let unitFlags = Set<Calendar.Component>([.hour, .year, .minute, .day, .month, .second])
var calendar = Calendar.current
calendar.timeZone = .current
let components = calendar.dateComponents(unitFlags, from: fireDate)
let newDate = Calendar.current.date(from: components)
notificationTriggerCalendar = UNCalendarNotificationTrigger.init(dateMatching: components, repeats: true)
}
