Add badge when push received in Swift

I have iOS app written in Swift. I use Parse SDK for push notifications. I want to add badge to app icon when push is received. There is problem - I can't add badge from push directly because there are a lot of users that use previous version of my app. And if I add badge from push - this badge will not disappear because previous app versions don't hide badge after it opened. So badge will be always on icon.

So what I want is to handle push by my app. No matter is it running or not. If push arrives - my app adds badge. So I can I handle push by my app if it is not running?

I know how to add badge with Swift

application.applicationIconBadgeNumber = 5

But how can i do it without opening the app - just when push is received?

since Parse SDK keeps it's own badge count separate from iOS app badge count, you need to follow it like this to rest the badge count to zero.

- (void)applicationDidBecomeActive:(UIApplication *)application {
  PFInstallation *currentInstallation = [PFInstallation currentInstallation];
  if (currentInstallation.badge != 0) {
    currentInstallation.badge = 0;
    [currentInstallation saveEventually];
  }
  // ...
}

In Swift 2.0,

let parseinst: PFInstallation = PFInstallation.currentInstallation();

if (parseinst.badge != 0)
{
     parseinst.badge = 0;
     parseinst.saveEventually()
}

To send push notifications with Parse just use the following code, making sure you change the channel to the correct one:

 let push = PFPush()
 push.setChannel("MyChannel")
 push.sendPushInBackground()

Then to hide the badges once the user opens the app back up, add the following function to your AppDelegate.swift:

 func applicationDidBecomeActive(application: UIApplication) {

    //Reset badge counter to zero
    var currentInstallation = PFInstallation.currentInstallation()
    if(currentInstallation.badge != 0){
        currentInstallation.badge = 0
    }
 }

When you push the app, you need to send the badge count with it:

{
    "aps": {
        "alert": "message goes here",
        "sound": "sound.aiff",
        "badge": 5 
    }
}

This will change the badge number on the app before it has been opened.

Please note that you cannot change the badge number of an app when it is closed without using notifications to do so.

Like said in the Parse docs, you can set badge number setting the badge field in the payload with an integer ex:

"data": {
          "alert": "The Mets scored! The game is now tied 1-1.",
          "badge": 5,
          "sound": "default",
          "title": "Mets Score!"
        }

or with Increment to automatically increment current value in badge count ex:

"data": {
          "alert": "The Mets scored! The game is now tied 1-1.",
          "badge": "Increment",
          "sound": "default",
          "title": "Mets Score!"
        }
