I have an android app and i want to make a iPhone version of it. it uses:

RevenueCat
Firebase
in App subs

the result functionally  should be the same to the android app and UI should be better and the app should be uploaded to the app store and must gets accepted.

I want to have this app accepted in the appstore  (must).
I want the app to be the like the android app
I want the app to use RevenueCat & Firebase & in app subs
