Remarks
Application developers can use this method to activate Handoff on a connected device or computer. The type is the activity identifier and must have a corresponding entry in the handling app's info.plist file as part of the NSUserActivityTypes array. By convention, the type starts with a domain-reversed string indicating the originating company, for example, com.xamarin.SomeApp.SomeVerb.
Either the userInfo or the webpageURL must be non-null. The webpageURL is intended for situations where a browser-based continuation of the activity is appropriate. The userInfo is used for device-based continuations. The userInfo can contain arbitrary key-value data to provide context to the handling application.
