SwiftUI views have no viewDidLoad or viewWillAppear like UIKit. How does a view actually get created, appear, update, and disappear? Center your answer on how the lifetime of the view struct differs from the lifetime of its state (@State).
The view struct is rebuilt on every update, but as long as identity holds, state carries over. When the view joins the tree onAppear and task run, every state change re-evaluates body, and when it leaves the tree onDisappear runs and the task is canceled automatically.
