+
+    1. Go to your [auth settings](https://supabase.com/dashboard/project/_/auth/url-configuration) page.
+    2. Enter your app redirect URL in the `Additional Redirect URLs` field. This is the URL that the user gets redirected to after clicking a magic link.
+
+    The redirect callback url should have the format `[YOUR_SCHEME]://[YOUR_HOSTNAME]`. Here, `io.supabase.user-management://login-callback` is just an example. You can choose whatever you would like for `YOUR_SCHEME` and `YOUR_HOSTNAME` as long as the scheme is unique across the user's device. For this reason, typically a reverse domain of your website is used.

+
+    Now add a cutom URL to your application, so the OS knows how to redirect back your application once the user clicks the magic link.
+
+    You have the option to use Xcode's Target Info Editor following [official Apple documentation](https://developer.apple.com/documentation/xcode/defining-a-custom-url-scheme-for-your-app#Register-your-URL-scheme).
+
+    Or, declare the URL scheme manually in your `Info.plist` file.
+
+    ```xml Info.plist
+      <?xml version="1.0" encoding="UTF-8"?>
+      <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
