Turnkey AASA Hosting

The service generates an AASA JSON response for a configured domain and app profile. Your app still needs the Associated Domains entitlement.

Automatic AASA JSON

iOS Ecosystem Parity

Universal Link handoff depends on Apple’s domain verification, app configuration, and the context in which a link is opened.

Swift SDK: iOS 13+

Domain Configuration

Review the Team ID, bundle ID, associated paths, and hosted AASA response before device testing.

Frequently Asked Questions

Everything you need to know about iOS Universal Links.

What is an AASA file?

An Apple App Site Association (AASA) JSON file resides at /.well-known/apple-app-site-association on your web server to prove domain ownership to iOS.

How does WilderLinks host AASA files automatically?

The service builds and serves JSON from the domain’s configured iOS app IDs and paths at /.well-known/apple-app-site-association. AASA itself is not HMAC-signed.

Can I use my own custom domain for Universal Links?

You can add and verify a custom domain, then attach an iOS app profile and configure its Associated Domains entitlement.

What happens if Apple changes its AASA JSON schema in new iOS versions?

Keep the app profile, entitlement, and association response aligned with Apple’s current requirements; automatic standards monitoring is not verified here.

Do Universal Links show a browser prompt dialog to the user?

A verified Universal Link can open the installed app directly. Handoff still depends on OS verification and how the link is opened.
