The following are some new open source and documentation resources I have identified that greatly assist in the development of iOS applications:

• Google API Client Library for Objective-C–These libraries will assist in any communication using Google’s authentication, JSON, or data API’s.
• Best Resources in iOS Development–This is the September 2011 installment of the ManicDev web site list.
• SVGKit–Open source framework for rendering SVG on iPhone. This library does not support gradients, however, so this would need to be added.
• Google API’s Client Library for .NET–These libraries assist in the development of services using .NET and WCF that act as a “proxy” to iPhone applications.
• Useful iOS Client Libraries and Classes–A list of highly useful open source libraries and frameworks for iOS development.
• make-fmwk–Script to create a static library based framework that eases references to open source libraries in Xcode projects.

Colin Wheeler posted a most excellent article on proper memory management in Objective-C that is among the best I have ever seen that actually includes some practical best practices in sticky situations (like when to take momentary ownership of an object that may be accessed concurrently to ensure it lives during the context of an operation to be performed on it).
