Sth about WWDC
I remembered there's a message that says that you cannot modify this video or whatever at the end of every session. So, if I trim the video and send it to my friend, is it allowed? Bonus: where can I find the background music for every daily debrief video (if I can)?

SwiftUI Refreshing Mechanism
SwiftUI's Refreshing mechanism is driving me crazy. Say that I have this view: NavigationView { List($datasource) { $item in NavigationLink { SubView(item: $item) } label: { Text(item.someAttribute) } } } SubView: TextField("Placeholder", text: $item.someAttribute) And each time I edit the value in the SubView, the SwiftUI's navigation controller retreats the view to the home page(the initial view). Why?
