4. Registering Custom URL Schemes
   In your plist
   If more than one third-party app registers to handle the same URL scheme ¯\_(ツ)_/¯

8. Some extra stuff
   ● Visit http://handleopenurl.com/ to get a list of schemes
   ● Use custom URL schemes to have a Today Extension
   communicate with your app

9. Using Universal Links (from the docs)
   ● Unique. Unlike custom URL schemes, universal links can’t be claimed by
   other apps, because they use standard HTTP or HTTPS links to your website.
   ● Secure. When users install your app, iOS checks a file that you’ve uploaded
   to your web server to make sure that your website allows your app to open
   URLs on its behalf. Only you can create and upload this file, so the
   association of your website with your app is secure.
   ● Flexible. Universal links work even when your app is not installed. When your
   app isn’t installed, tapping a link to your website opens the content in Safari,
   as users expect.
   ● Simple. One URL works for both your website and your app.
   ● Private. Other apps can communicate with your app without needing to know
   whether your app is installed.

10. Adding support for Universal links
    ● Create an apple-app-site-association file that contains JSON data about
    the URLs that your app can handle.
    ● Upload the apple-app-site-association file to your HTTPS web server.
    ● Prepare your app to handle universal links.

11. Server side
    Add a apple-app-site-association to the root of your server (prefix can be found in
    provisioning portal.)

12. Client Side

13. Client side
    ● Update your app delegate to respond appropriately when it receives the
    NSUserActivity object.

14. Some extra stuff
    ● Work in SFSafariViewController, don’t work in UIWebView
    ● Debugging the apple-app-site-association is hard
    ● Some popular app don’t support them, e.g. gmail
    ● Actions are remembered
