We're back in February with Krzysztof Zablocki ( (@merowing_ (, who will be presenting Objective-C Playgrounds ( while he's in town visiting from Warsaw.

Playgrounds are one of the niftiest features of Swift. They allow you to quickly test out bits of code and see results in real time, without going through the traditional edit-compile-run-debug cycle.

Krzysztof will present his KZPlayground ( project, which makes playgrounds possible in Objective-C, where they can in fact be even better than their counterpart in Swift. Krzysztof will also present how you can use runtime/code injection to get most out of your time.

Ariel Michaeli ( (@arielmichaeli ( of appFigures ( will also kick things off with a by-the-numbers presentation on how the App Store grew and changed in 2014, and what we can expect in 2015.

We're glad to be back this month at the beautiful XO Group ( offices. Pizza, beer, soda, and wine will be served. Thanks to Bec, Matt, and the rest of the team for hosting!
