Some folks have asked me to write about my impressions on iOS 7. Unfortunately, as an iOS developer I am bound by the NDA (non-disclosure agreement) regarding software and features that are not yet released. In essence, if Apple did not show the information at their WWDC Keynote, it can't be discussed with the general public. While Apple did show a lot of good stuff in the keynote, the things that I found most interesting were not shown/described in the keynote and therefore under NDA.
I currently have the iOS 7 beta installed on an old phone and I have been trying out its various features and getting a better idea of how its new design language works. Folks, rest assured that I will write about iOS 7 when it becomes publicly available sometime this autumn with the release of this year's new iPhone.
