It's all about iOS 7

It is all about iOS 7. SO here is a list of resources you will surely enjoy:

• Apple Design Goes Flat with iOS 7 - the title of the blog post is a little misleading as the author gives an overview on the deference, clarity, and depth themes of iOS 7. 
• iOS 7 by Tutorials - book with a lot of tutorials on iOS 7 APIs (UIKit Dynamics, Motion Effects, Text Kit, Unite testing / CI in Xcode 5, and many more). The list of authors is impressive as well (Ray Wenderlich, Jeremy Olson, and many more). Haven't yet ordered the book, but it is on the top of my list.  
• The Essential iOS 7 Developer's Guide - similar to the above resource, it provides 11 guides to iOS 7. Each tutorial is small and to the point, easy to read and go through, while also providing a little bit of code as well.
• iOS 7 review - great, comprehensive, and more importantly a balanced review of iOS 7 written by Rene Ritchie of iMore. 

Short list of iOS 7 resources I've found useful

Few iOS 7 resources I've stumbled upon, mostly through Twitter. I will not include the obvious Apple ones, as you should have already read all of them by now, twice!

• ios7.io - A selection of iOS7 specific links covering icons, designs, apps, and much more. 
• iMore.com - A collections of iOS 7 news from no other than Rene Ritchie. 
• iOS 7 Apps Redesign - Various redesign of apps to match iOS 7 guidelines, with a screenshot of a before and after.
