Passing Variables into other Variables and across files with SwiftUI - ipados

Question

I want this file(file2) to revvieve edge input results of file1, modify them as desired then send them along to file 3 (charts) for realtime feedback. how do I pass variables into other variables as well across files while keeping the information live and modifiable?

DART Edge Live Data Passing and Editing Interface
I have tried other methods to pass data that cater to specific scenarios such as pdf rendering or grabbing image of the day, etc but I need something specific to math and science where variables can be manipulated live while updating other variables. I’m looking for the most optimal method to pass and manipulate data so I can pass the whole math lab via a scenario down the road such as cloud scaling. If it is specific to math or science I don’t quite have SwiftUI down with things like: State, Static, ObservableObject, Object, Published, etc.
I am developing solely on iPad Pro 6th gen Swift Playgrounds.
