Answer 1

You need to upload apple-app-site-association file to the root directory of the server(from where you need to redirect to your installed app).

e.g- Suppose you have to redirect from www.abc.com/getapp then you need to upload the apple-app-site-association file to the root directory where the www.abc.com is get hosted.

Steps to support universal links-

1. Create your apple-app-site-association file(Suppose your universal link is www.abc.com/getapp and you want to redirect in your app from here).

   {
    "applinks": {
       "apps": [],
       "details": [
           {
               "appID": "9JA89QQLNQ.com.apple.wwdc", //9JA89QQLNQ is your team ID & com.apple.wwdc is your bundle id
               "paths": [ "/getapp"]
           }
       ]
     }
   }
   

2. Upload this file to the root directory where www.abc.com is hosted.

3. Validate at http://branch.io/resources/aasa-validator/. If the file is valid then all checks would be green.

4. Now prepare your app to support universal links-

   a. Go to developer.apple.com and enable Associated Domains to your app ID.

   b. Select your target and turn on Associated Domains switch.

   c. Add applinks:abc.com.

   d. Add application:continueUserActivity:restorationHandler: app delegate method so that your app can receive a link and handle it appropriately.

Not getting callback to the app-

1.When a user is browsing your website in Safari and they tap a universal link to a URL in the same domain as the current webpage, iOS respects the user’s most likely intent and opens the link in Safari.

2.Copy and paste your universal link(http(s)://www.abc.com/getapp) to notes and tap on it. It your app can handle this link you will get the option Open in "AppName".
