The other significant problem with creating a new version instead of offering updates to the same app is that you lose your search ranking on the App Store when you create a new SKU. Allen Pike looks into the problem by investigating the search results for the term “Twitter” on the store and finds some pretty shocking results. Wallpapers HD, really?
I’m not entirely sure how I feel about this but I think I like it. It creates a new local scope for variables and is easier than the struct dance that we need to do to assign to things like frame and bounds properties. Interesting little technique.
It’s easy to forget about the open source Omni Frameworks but there are some really useful bits of code in there. In this post, Amy Worrall looks into implementing their document picker which mirrors the style of the Apple document pickers in iWork for iOS.

This isn’t directly related to iOS development but I couldn’t resist linking to it as it is a fantastic piece of work. Get structured data out of PSD files as well as being able to read and write them. It would be wonderful if this was ported to Objective-C.
I am sure we all know how important typography is to working with the iOS and OS X platforms. If you are not quite there yet with it then this well crafted online book written by Matthew Butterick might be a good place to start. There is a ton of great information in here but I particularly found the section on font alternatives to the most popular fonts useful.
Ben Thompson with a really insightful article on Facebook on mobile. I hadn’t even considered the “full screen” advertising aspect of the Facebook feed but it’s so obvious when it’s pointed out.
Nathan Vella takes an in depth look at the sales figures from Sword & Sworcery across multiple platforms, not just iOS. It’s amazing to see the iOS sales stack up so high even against things like multiple Humble Bundle deals, especially in terms of revenue.
