Building for iOS and Air SDK 15.0

Hello,

After being forced by apple to update to Air SDK 15.0 beta to continue to deliver updates for my app, I can no longer build my application (although I can still build for my Android version of the game).

Here's the "error" that breaks the build. Even though it says its just a warning that its going to use the default implementation like it should do, there is no way to build around it. Any ideas?
