Schedule Local Notifications at Specific times in the day

Question

I want to setup a daily notification system for my app. It should notify the user twice a day, once at 8:00 AM (Hey there, your set of morning doses is ready. Wanna check it out?) and once at 7:00 PM (Ssup! Your evening Dose is waiting inside). I know that by doing this i'll run out of notifications in a month since there's a 64 notifications cap (for local notifications) but by then, the app will be live and i'll be done setting up remote notifications update.

I've looked at this question: How to schedule a same local notification in swift and the .Day is all good. I just need to know how to do it twice a day at those specified times;. Thanks in advance!

EDIT: how to set the specific time on the notification is part of the problem. The NSDate API is giving me funny time intervals (sinceNow/Since1973). I just want to set it to fire at 7 PM. :-/ Can't quite seem to do it with these NSDate apis unless I'm missing something.

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // Override point for customization after application launch.
    let settings = UIUserNotificationSettings(forTypes: .Badge, categories: nil)
    UIApplication.sharedApplication().registerUserNotificationSettings(settings)

    let localNotification1 = UILocalNotification()
    localNotification1.alertBody = "Your alert message 111"
    localNotification1.timeZone = NSTimeZone.defaultTimeZone()
    localNotification1.fireDate = self.getEightAMDate()
    UIApplication.sharedApplication().scheduleLocalNotification(localNotification1)

    let localNotification2 = UILocalNotification()
    localNotification2.alertBody = "Your alert message22"
    localNotification2.timeZone = NSTimeZone.defaultTimeZone()
    localNotification2.fireDate = self.getSevenPMDate()
    UIApplication.sharedApplication().scheduleLocalNotification(localNotification2)
    return true
}

func getEightAMDate() -> NSDate? {
    let calendar: NSCalendar! = NSCalendar(calendarIdentifier: NSCalendarIdentifierGregorian)
    let now: NSDate! = NSDate()

    let date10h = calendar.dateBySettingHour(8, minute: 0, second: 0, ofDate: now, options: NSCalendarOptions.MatchFirst)!
    return date10h
}

func getSevenPMDate() -> NSDate? {
    let calendar: NSCalendar! = NSCalendar(calendarIdentifier: NSCalendarIdentifierGregorian)
    let now: NSDate! = NSDate()

    let date19h = calendar.dateBySettingHour(19, minute: 0, second: 0, ofDate: now, options: NSCalendarOptions.MatchFirst)!
    return date19h
}
