Look a little bit in Everything You Wanted to Know About How SWF get into an IPA for iOS
when Adobe/Harman generate an app for iOS, from SWF, assets, etc.
it is their responsibilities to compile those things, that is “supporting air captive runtime for iOS”
but in the case of “external” assets like
Assets.car, icons, launch screen storyboard etc.
(they are external to the project but at the same time they are embedded in the final app)
those are things imposed by the platform, in this case iOS
it’s not really that Harman supports it or not, in short they support anything that can be embedded into the final app, but then for “special file and formats” you might need to generate them yourself or use a 3rd party app or process to generate those
but if you look at it, it’s like having an app icon of 1024 x 1024 and use a graphic converter to generate another icon of 512 x 512 etc.
if ADT can supports it, even better, but in the case it is something new/recent imposed in the platform, then you will have to jump through a bit more loops to generate those
