How to make a native chat app in Swift?

How can I Initiating a chat between two non Facebook friends via a FB app?

• I'm working on a FB app that does introductions, and I'm looking for a way to make the app to introduce and initiate a chat between two Facebook users who are not direct friends. Since messages from non-friends aren't alerted/notified in the menu upper bar, I was wondering if there's another way to use the API to initiate a chat that the users will actually see (I have both users FB credentials). I thought about using the request API but the redirect URL must be owned by the app so I cannot redirect to the FB messages.

  Hey If You Find A Loop Between Them Say One Or More Mutual Friend(s) The Message Will Go Straight Into Inbox..! I Hope This Works Out ..! Else You Can Consider Notifying Both Of Them Through Your App..!
