+::: note
+On iOS 17.4+ and macOS 14.4+ it is possible to use Universal Links as callback and logout URLs. When enabled, Auth0.swift will fall back to using a custom URL scheme on older iOS / macOS versions.

+This step requires a paid Apple Developer account. It is needed to use Universal Links as callback and logout URLs. Skip this step to use a custom URL scheme instead.

-### Configure a Custom URL Scheme
+#### Configure the Team ID and bundle identifier
+
+Scroll to the end of the settings page of your Auth0 application and open **Advanced Settings > Device Settings**. In the **iOS** section, set **Team ID** to your [Apple Team ID](https://developer.apple.com/help/account/manage-your-team/locate-your-team-id/), and **App ID** to your app's bundle identifier.
 
-Back in Xcode, go to the **Info** tab of your application target settings. In the **URL Types** section, click the **＋** button to add a new entry. There, enter `auth0` into the **Identifier** field and `$(PRODUCT_BUNDLE_IDENTIFIER)` into the **URL Schemes** field.

-<p><img src="/media/articles/native-platforms/ios-swift/url-scheme.png" alt="Custom URL Scheme"></p>
+This will add your app to your Auth0 tenant's `apple-app-site-association` file.
 
-This registers your bundle identifer as a custom URL scheme, so the callback and logout URLs can reach your application.
+#### Add the associated domain capability
+
+In Xcode, go to the **Signing and Capabilities** [tab](https://developer.apple.com/documentation/xcode/adding-capabilities-to-your-app#Add-a-capability) of your app's target settings, and press the **+ Capability** button. Then select **Associated Domains**.
+
+<p><img src="/media/articles/native-platforms/ios-swift/ios-xcode-capabilities.png" alt="Screenshot of the capabilities library inside Xcode"></p>
+
+Next, add the following [entry](https://developer.apple.com/documentation/xcode/configuring-an-associated-domain#Define-a-service-and-its-associated-domain) under **Associated Domains**:
+
+```text
+webcredentials:${account.namespace}
+```
+
+If you have a [custom domain](/customize/custom-domains), use this instead of the Auth0 domain from the settings page.
+
+::: note
+For the associated domain to work, your app must be signed with your team certificate **even when building for the iOS simulator**. Make sure you are using the Apple Team whose Team ID is configured in the settings page of your Auth0 application.
