iOS Drag & Drop Homescreen experience

I would like to create an app that could have its own inbuilt "widgets" system which are essentially SwiftUI structs with a size reference, then I would like to be able to add/remove these on its own inbuilt screen within the app itself that replicates the iOS home screen, so being able to drag and drop and reorder the widgets on the view similar to how it's done on the real iOS home screen

I hope this makes sense
