Chris Scott (the creator of ColdSpring) has released a new IoC / MVC framework for Flex called Swiz. This is really going to shake up the Flex MVC space and hopefully make people realize that Cairngorm is not the best option out there. The moment I saw code generation tools springing up to help make life with Cairngorm easier it confirmed my belief (and those of my colleagues) that CG makes things more complicated than they need to be.
Chris and I have been talking about the design of Swiz for the past few months during its evolution. As time goes on I hope to contribute in as many ways possible, including docs, sample apps and hopefully some framework code too.
