“show when run”

I am new in Xcode. When I try to practice Swift code to run the code . When I press run its show nothing. I search to solve it through YouTube. But I can't.

I'm on XCode 6.4 (6E35b)Two days ago XCode stopped showing errors in the editor. Everytime I do a build, it says 'build succeeded' but when I try to run the app or my unit tests then it says build failed but it doesn't show the red exclamation points in the editor and I have to go into the logs view and hunt through the logs to find the compile errors. I trashed my version of XCode and re-installed through the AppStore, same behavior. I do have XCode 7 downloaded but I haven't run it in weeks. I'm on Yosemite 10.10.1.Has anyone else seen this behavior before? Seems weird. I've tried toggling some of my preferences related to showing errors as well to no avail.

Seeing as contextMenu as been deprecated and they are Menus shown on a long press, how can that be achieved with SwiftUI? I haven't found a new initialiser for Menu yet to show on a long press or an isPresented argument.

I have a List in a NavigationStack and the list items have swipeActions struct ListItem: Identifiable { var id: String { return name } let name: String } struct ContentView: View { @Environment(.editMode) var editMode @State var listItems = [ ListItem(name: Cow), ListItem(name: Duck), ListItem(name: Chicken) ] var body: some View { NavigationStack { List(listItems) { listItem in NavigationLink { Text(listItem.name) } label: { Text(listItem.name) } .swipeActions(edge: .trailing) { Button(action: { }, label: { Text(Edit) }).tint(.blue) Button(role: .destructive, action: {}, label: { Text(Delete) }) } } .navigationTitle(Animals) .navigationBarItems(trailing: EditButton()) } } } For users who might have problems with the swipe gesture, I would like to have the Swipe Actions display when the list is in editMode. Is there a programmatic way to show the swipeActions? I have also tried using ForEach with an onDelete modifier. Then if you hit the edit button, it shows a circular button on the left fo
