As I\'m reading, iOS 9 introduced Universal Links. In the \"Support Universal Links\" section in Apple\'s App Search Programming Guide, it says that this is not exactly like
This is a sample Universal Link: “http://sample-universal-link.demoapp.com”
It is unique, and on being tapped it will either open the App without going through Safari(if the App is installed) or will open the website on Safari( if the App is not installed)
This is a sample URL Scheme: “demoapp” (demoapp://params)
This may not be unique, and on being tapped it will open the App if it is installed. If the App is not installed, it will do nothing. One or more App may have same URL Scheme.
Implementation (requirements) for Universal Link & URL Scheme are quite different, so I highly doubt that Universal links replaces URL Scheme.
Universal Link is one of the way to implement deep linking.
