Detecting if the app launched from Handoffs or Universal Links

Is there a reliable/correct way to determine in the

application:continueUserActivity:restorationHandler:

method if the app was opened as a in my app but I need to be able to distinguish the source without having to add anything to the URL.

I've looked through the properties of

NSUserActivity

but nothing there seems to help, since

activityType

returns

NSUserActivityTypeBrowsingWeb

for both Handoffs and Universal Links.

So, is there a correct way to do this or am I supposed to handle both in the same way without knowing the source?

This is essentially what I'm hoping is possible to accomplish...

func application(application: UIApplication, continueUserActivity userActivity: NSUserActivity, restorationHandler: ([AnyObject]?) -> Void) -> Bool {
if handoff {
     ...
     return true
} else if universalLink { 
     ... 
     return true 
} 
return false
}
