title: Send Local Notifications while App is running in the background Swift 2.0
body: <p>I am trying to send the user a 'Push Notification style' Alert when the user minimizes the app (by clicking on the iPhone's Home Button or by locking the phone as well). </p>
  
  <p>My app continuously parses an XML file (every 10 seconds) and I want the app to continue running so that it sends the user a Local Notification once some condition has been met in my program, even after the user has minimized the app or locked their phone.</p>
  
  <p>I've bounced around from tutorials and everyone seems to 'schedule' a Notification, but this isn't going to work for me because my Notification isn't time-based, rather it's based off conditions being met.</p>
  
  <p>What I've done so far:</p>
  
  <p><strong>AppDelegate.swift</strong></p>
  
  <pre><code>func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -&gt; Bool {
      // Override point for customization after application launch.
      application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil))
      return true
  }
  </code></pre>
  
  <p><strong>MapViewController.swift</strong></p>
  
  <pre><code>// Some function
  func someFunction(delta: Int) {
      if delta &lt; 100 {
          // Send alert to user if app is open
          let alertView = UIAlertController(title: "This is an Alert!", message: "", preferredStyle: UIAlertControllerStyle.Alert)
          alertView.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: nil))
          self.presentViewController(alertView, animated: true, completion: nil)
  
          // Send user a local notification if they have the app running in the bg
          pushTimer = NSTimer.scheduledTimerWithTimeInterval(0.5, target: self, selector: Selector("pushNotification"), userInfo: nil, repeats: false)
      }
  }
  
  // Send user a local notification if they have the app running in the bg
  func pushNotification() {
      let notification = UILocalNotification()
      notification.alertAction = "Go back to App"
      notification.alertBody = "This is a Notification!"
      notification.fireDate = NSDate(timeIntervalSinceNow: 1)
      UIApplication.sharedApplication().scheduleLocalNotification(notification)
  }
  </code></pre>
  
  <p>The Alert works great while the app is open, but the notification never shows up when I minimize the app on my phone. I assume the app isn't running while it's in the background or I don't understand this concept that well. Any help is greatly appreciated.</p>
