What do you mean by deep linking in iOS?
Deep links are links that send users directly to an app directly instead of a website or store using URI (Uniform resource locator) or universal links. The URL scheme is a well-known method of having deep links, but Universal Links are Apple's new approach to connecting your web page and your app under the same link. Deep linking involves not only creating a clickable link that opens up your app, but also a smart one that navigates to the resource you desire. Users are directed straight to in-app locations using these links, which saves them the time and effort of finding those pages themselves thus improving their user experience tremendously.
