Run the unmodified iOS kernel image on the Khadas VIM3 (2)

I would like to know what is the use of running iOS kernel on any device? What is the objective behind it ?

AFAIK even if it runs, there wont be any support for the UI or any kind of app. Also once Apple see this then they will try to block the progress of such work.

Maybe I am not aware of the objective here. Please explain.

Thanks.
