How-To

Hosting Checklist

  1. 1

    Name it exactly right

    The file is apple-app-site-association — no .json extension.

  2. 2

    Place it at the well-known path

    https://yourdomain.com/.well-known/apple-app-site-association, reachable without redirects.

  3. 3

    Serve the right header

    Content-Type: application/json over valid HTTPS.

  4. 4

    Add Associated Domains in Xcode

    Signing & Capabilities → + Capability → Associated Domains → applinks:yourdomain.com.

  5. 5

    Validate it

    Run the AASA Validator against your domain — it checks DNS, HTTPS, headers, JSON, and your app ID.
