Not sure if the decision was made due to iOS7, but mine (Paid version) doesn't run on iOS7.
IMHO, this is needed even more in iOS7. Some of the UI design choices on iOS7 are terrible like the removal of button backgrounds/borders. I upgraded an iOS6 app to iOS7 and gave it to a friend and he just stared at it because he didn't realize that there were buttons on the screen for him to click on.
Yeah, I've written some nasty bug reports to Apple about some of those horrible UI changes and have had many unproductive discussions on the developer forums (as that isn't the place anyway).
I hadn't tested Pixate under iOS yet. So, it does't work eh? What's happening?
The Simulator wont start but I didn't really look into it. Ever since the first β iOS that Apple developed, they usually do massive changes so I'll wait until β 6+ to re-test it out.
