Today I got news from Apple that every app should be optimise before 1 Feb. Please could you tell me what is this. I am using mac 10.9 and xcode 5. I am testing app on IOS7 iphone 4. May i need to do something extra to optimise app for ios 7. 
so no worries.
Small print: " iOS Human Interface Guidelines." ← those don’t mean sh!t with Unity games.
Thanks
