I’m at the Silicon Valley iPhone Developer’s meetup tonight and it’s packed, much more than usual. Presenters are providing overviews of new developer tools for app developers.

ARKit is an open source toolkit for developing augmented reality apps that while early in ongoing development shows some great signs of lowering the barriers for AR app development.

Briefs is a highly polished rapid prototyping tool with a hysterical icon (which I’ll post when I’m at my laptop), that has sophisticated process flows and collaboration features. Seems like an invaluable tool for any designer and developer team. Website is giveabrief.com.
