Fingerprint for iOS version 2.0 introduces significant enhancements aimed at improving device identification capabilities for mobile developers, addressing the need for precise visitor recognition on both web and mobile platforms. The latest version offers new features such as a request identifier for querying server API details, linked ID support for associating iOS identification events with internal identifiers, and a more comprehensive backend response that includes IP address, location, and detection confidence. Additionally, the SDK has been optimized for faster response times by eliminating dependencies on WKWebView and UI stack, and it now supports the async/await interface in Swift, enhancing the ease of implementation and interaction with fraud detection systems. These updates mark a substantial progression from version 1.0, making it easier for developers to integrate advanced device identification and security measures into their iOS applications.
