Question

How does iOS choose which app to launch when a generic URL Scheme is launched? What I know from older document is

Note: If more than one third-party app registers to handle the same URL scheme, there is currently no process for determining which app will be given that scheme.

OR Is there any latest document that states this?

Answer 1

As per Apple documentation: To ensure uniqueness, specify a reverse DNS string that incorporates your company's domain and app name. Although using a reverse DNS string is a best practice, it doesn't prevent other apps from registering the same scheme and handling the associated links. Use universal links instead of custom URL schemes to define links that are uniquely associated with your website.
