PFiddlesoft has updated its PFAssistive Framework to version 3.5.0. The PFiddlesoft Frameworks are two frameworks that help developers write assistive Macintosh applications for persons with disabilities using Apple's Accessibility and Quartz Event Taps APIs (application programming interfaces) on OS X.

The PFAssistive Framework has been updated to add support for client applications that are written using the new Swift programming language. It also adds support for new accessibility features introduced by Apple late last month in OS X El Capitan, improved power, speed and efficiency, and a few minor bug fixes.

The frameworks are written using Objective-C. They support the Intel 64-bit architecture using reference counted memory management or ARC, and they support client applications written in Objective-C or Swift. Developers can now license the PFiddlesoft Frameworks for distribution or for use with their own products that use Apple's Accessibility and Quartz Event Taps technologies.

The frameworks may be licensed free of charge for personal use or for distribution or use with a free software product. A license fee is required to distribute or use the frameworks with a product for which payment is requested or required. Source code is available for a separate fee. Different terms apply to large or established commercial software developers. For more information, go to pfiddlesoft.com/frameworks/.
