Overview
To begin with iOS, it is essential to understand an important concept. To establish trust between your app and your website, you need to configure an Apple-App-Site-Association (AASA) file. This file is crucial for enabling passkeys for your Flutter app and the configured RPID. The following chart explains the concept in detail
iOS: Configure project.AASA file caching and the ?mode=developer parameter
When a user installs or updates your app, iOS retrieves the AASA file from your website. To optimize performance and reduce server load, Apple caches this file using a Content Delivery Network (CDN). However, this caching mechanism can introduce delays when updating the AASA file, as changes might take up to 48 hours to propagate.
During development, waiting for cache updates is impractical. To address this, iOS provides a ?mode=developer parameter that allows your app to fetch the latest AASA file directly from your server, bypassing the CDN cache.
Do not use the ?mode=developer parameter in your production release. This parameter is intended for development purposes only. Using it in production will prevent iOS from properly detecting your AASA file, which will break passkey functionality in your released app.
