Brand new project from Francis Chong for parsing HTML documents with a chainable syntax for quickly finding and modifying an HTML (or XML) document. I haven't had a chance to test this out yet but it's a problem I have struggled to solve before so I thought it might be worth a look.
If you have ever tried to customise the visuals of a UIPopoverController then you will appreciate this replacement from Nicolas Cheng. This is a reimplementation of a popover controller rather than a simplification of the existing customisability but the upside is that it supports the iPhone as well as the iPad.
I really like the expansion to the "swipe to delete" gesture that Apple is using in iOS 7 and the platform has been needing a more consistent way to expose functionality like this across apps. This post sees Ash Furrow implement a "swipe to delete, and more..." control with a nice step by step walkthrough of the code needed.
ReactiveCocoa got a 2.0 release this week, the (huge) list of changes here gives a great sense of what has changed. The 2.0 API is incompatible with 1.x releases so approach upgrades with a little caution but if you haven't had a chance to check RAC out yet then this may be a good point to take a look.
