swift – How can I ship an iOS native push to a selected date and schedule it weekday for a selected time?

I wish to add and ship an iOS native push notification to a selected date and wish to schedule it by weekday for a selected time (hour, minute). I needed to ship this reminder weekday-wise however wish to take away at present’s if use already took/achieved his at present’s objective. I’ve tried with the code under however didn’t ship it, please verify the code under.

import UIKit
import UserNotifications

public extension Date {
    func midday(utilizing calendar: Calendar = .present) -> Date {
        calendar.date(bySettingHour: 12, minute: 0, second: 0, of: self)!
    }
    func day(utilizing calendar: Calendar = .present) -> Int {
        calendar.element(.day, from: self)
    }
    func weekday(utilizing calendar: Calendar = .present) -> Int {
        calendar.element(.weekday, from: self)
    }
    func hour(utilizing calendar: Calendar = .present) -> Int {
        calendar.element(.hour, from: self)
    }
    func minute(utilizing calendar: Calendar = .present) -> Int {
        calendar.element(.minute, from: self)
    }
    func second(utilizing calendar: Calendar = .present) -> Int {
        calendar.element(.second, from: self)
    }
    func including(_ element: Calendar.Element, worth: Int, utilizing calendar: Calendar = .present) -> Date {
        calendar.date(byAdding: element, worth: worth, to: self)!
    }
    func monthSymbol(utilizing calendar: Calendar = .present) -> String {
        calendar.monthSymbols[calendar.component(.month, from: self)-1]
    }
    func addDay(n: Int) -> Date {
        let calendar = Calendar.present
        return calendar.date(byAdding: .day, worth: n, to: self)!
    }
