chore: cleanup ios examples

This PR: - Removes developer comments + Todos - Changes the samples to use @StateObject for the RiveViewModel instances. This is the SwiftUI way to instantiate an ObservableObject. This also ensures the Rive data is only loaded when the view is displayed and not when the app is started. The `view` method may also be called multiple times for various reasons, so moving this logic to be in the view state is more efficient. @mjtalbot I think you made comments about this in the past. By doing the above it also fixes the samples in `SwiftWidgets` that was giving issues - For example, the sliders didn't work. It does now. - The toggle `RSwitch` still does not work, as it's an Animation and not a StateMachine (I believe there is now logic that disables touch events if there are no active listeners, or it only does touch processing when it's a state machine). - We should remove this file entirely or just keep the sliders. This seems to have been made before state machines were a thing, and implementing buttons etc. should rather be done through listeners and events. ### TODO - Some samples still create the RiveViewModel in the view but rely on other state data. Need to check to see what is the correct way to lazily create those. Diffs= fbb092d8c chore: cleanup ios examples (#6351) Co-authored-by: Gordon <pggordonhayes@gmail.com>
