The FusionAuth Swift SDK for iOS Beta streamlines mobile development by offering equally powerful backend capabilities and seamless integration with preferred frameworks. The SDK eliminates boilerplate code, leading to cleaner and more efficient applications. It provides a simple and trustworthy interface to authenticate mobile users with FusionAuth, allowing developers to use OAuth 2.0 and OpenID Connect functionality in their iOS apps. The SDK is written in Swift and compatible with Object-C, and it uses AppAuth-iOS for the OAuth 2.0 Authorization Code Grant flow and OpenID Connect functionality. It simplifies authentication flows, introduces standardized usage, handles best practice defaults, saves time, maintains flexibility, and provides a secure way to authenticate users. The SDK is designed to be easy to use, with a single import and simple configuration that handles all dependencies and best practice defaults. Developers can use the SDK to retrieve user info, call APIs with access tokens, and sign out users, while FusionAuth takes care of security features such as account locking, password rules, webhook notifications, and more. The SDK also allows for customization of the look and feel of hosted login pages, including themes and Tailwind CSS examples.
