Apple Technologies?

"Submit any app you have worked on that demonstrates creative use of Apple technologies and runs on an Apple platform."

Apart from the given examples, which are fairly new additions to the platforms, are frameworks such as UIKit, Passkit, etc., considered technologies? Would, for example, talking about custom built UI controls be appropriate?

Also, is it allowed to provide links to screenshots/videos of the AppStore app in the essay, to prove certain features?

Thanks,

Sebastian
