How to assign firedate to datepicker

Question

I am trying to create an app. I need to send a notification daily at a time the user decides I have used a date picker for the user to decide when they get the notification. I am also found a way to get it repeat but now I am having trouble assigning the date picker to the fire date. Please answer in swift. code:

import UIKit

class TechByteSchedulingViewController: UIViewController {
   @IBOutlet weak var datePicker: UIDatePicker!

   @IBAction func SavePressed(sender: UIButton) {
       func sendNotification(sender: UIButton) {
           var localNotification = UILocalNotification()
           localNotification.fireDate = datePicker.date
           localNotification.repeatInterval = .CalendarUnitDay
           localNotification.alertBody = "check out your daily byte"
           localNotification.timeZone = NSTimeZone.defaultTimeZone()
           localNotification.applicationIconBadgeNumber = UIApplication.sharedApplication().applicationIconBadgeNumber + 1
           localNotification.soundName = UILocalNotificationDefaultSoundName

           UIApplication.sharedApplication().scheduleLocalNotification(localNotification)
    }

    func application(application: UIApplication, didReceiveLocalNotification notification: UILocalNotification) {
        application.applicationIconBadgeNumber = 0
    }

}

Here is the code from the app delegate class AppDelegate: UIResponder, UIApplicationDelegate is highlighted when I press done after setting the date picker

import UIKit

@UIApplicationMain class AppDelegate: UIResponder, UIApplicationDelegate {

var window: UIWindow?


func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    if(UIApplication.instancesRespondToSelector(Selector("registerUserNotificationSettings:"))) {

    application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: .Alert | .Badge | .Sound, categories: nil))
    var notification = UILocalNotification()
            // play default sound
    }

    // Override point for customization after application launch.

return true }

Can you give some information on what you're seeing that isn't working? Is it firing at the wrong time/not at all? — Braains, Jul 27 '15 at 19:18
When I hit the done button in my app it crashes and [class AppDelegate: UIResponder, UIApplicationDelegate] is highlighted — Soviet Union, Jul 27 '15 at 19:22
Can you provide the relevant lines from the console? The answer will be in there somewhere. — Braains, Jul 27 '15 at 19:23
@Braains Done the errors in the console are in my description — Soviet Union, Jul 27 '15 at 19:37
It looks to me like you have the "Done" button set in Interface Builder to trigger a selector called "DateChosen". If this is true then all you need to do is add that selector to your class. You can check this by going to your storyboard or nib file and selecting the done button and going to the outlets section of the inspector. — Braains, Jul 27 '15 at 20:57
