Not able to setup Deep linking or Universal linking for ios app

Question

I am a newbie in ios development and working on Universal deep-linking. I have added apple-app-site-association file to my website. (I have validated the file) Client enabled Associated Domains feature for the app and added me as a team member. He has an individual account and sent me an invitation for the app.

I have a couple of questions:

• Do I need to enable signing with my account (created by invitation) for Universal deep linking to work in the development phase?
• If yes then Issue is that I am getting "Your development team, "Bhaskar Dabhi", does not support the Associated Domains capability." maybe because he couldn't enable access to certificates, identifiers and profiles. Does he need to enable "access to certificates, identifiers and profiles" for me to Universal deep linking to work?
• if No then Universal deep linking is not working. not sure why.

I went through a couple of tutorials but couldn't figure out if it's because of signing in.

Answer 1

Universal Links

Step 1: Register your app at developer.apple.com.

Step 2: Enable ‘Associated Domains’ on your app identifier.

Step 3: Enable ‘Associated Domain’ on in your Xcode project.

Step 4: Configure your website to host the ‘apple-app-site-association’ file

AASA (apple-app-site-association) File

{
  "applinks": {
    "apps": [],
    "details": [
      {
        "appID": “*****.com.*****.ios",
        "paths": [
          "*"
        ]
      }
    ]
  }
}

Step 5: Host your AASA file on your domain. After validating it using AASA validator.
