title: How to open any URL clicked within my iOS app in the in-app browser?
body: <p>How can I set a rule such that when my user clicks any web link within my app, it opens in the in-app browser instead of Safari? </p>
  
  <p><strong><em>Context</strong>: I'm building an app that has several places where links are either embedded by me or are loaded through various user interactions, e.g. a link leading to a page that houses another link. I want to ensure that the user seldom leaves my app and hence want to open all external web links in an in-app browser that has already been developed</em></p>
  
  <p>Target Build: iOS 11.
  Environment/ Language: Swift 4</p>
