Hi,
Apple has notified with below statement, so wanted to make sure it doesn't mean to restrict AIR for developing iOS apps
(https://developer.apple.com/news/index.php?id=12172013a#top)
Make Your Apps Work Seamlessly with iOS 7
December 17, 2013
Starting February 1, new apps and app updates submitted to the App Store must be built with the latest version of Xcode 5 and must be optimized for iOS 7. Learn more about preparing your apps by reviewing the iOS Human Interface Guidelines.
Thanks,
Sanniv.
