title: How do I interrogate the current app's URL scheme programmatically?
body: <p>My iOS app has 50+ targets, each with their own custom URL scheme.  I need to detect if a request from a webview matches the scheme of the currently running app.  In order to do this, I need to be able to interrogate the current app's URL scheme(s) from code.  </p>
  
  <p>Similar questions deal with attempting to interrogate other apps to discover their URL schemes, which seems like it is not possible.  I need to find the scheme out for my own app, from within my app.</p>
  
  <p>I would like to avoid having to set another plist value to the URL scheme and including that with the target.</p>
  
  <p>Is there any way to get the URL scheme of the current app?</p>
