OK - we need something more. As explained here: Core Foundation Keys , the Plist key that AIR uses for icons, CFBundleIconFiles, is essentially deprecated, and the newer format, CFBundleIcons, has taken precedence over it since iOS 5.0. I guess this was never updated in AIR since it still continued to work. This newer dictionary contains a key, CFBundleIconName, which if it isn't present and pointing to a 1024x1024 appstore image, you won't be able to upload your app from XCode 9, even just for Testflight. Unfortunately our upcoming release contains iOS 11-specific features and cannot be built with an earlier version of XCode. Maybe there's a way to trick an earlier version of Xcode to upload it? In any case it's pretty clear this should be updated ASAP.
