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 have turned on code coverage (before running my unit tests), and clicked on Editor > Show Code Coverage, but the editor does not show the code coverage information along the right side of the editor window. It has appeared intermittantly, but then it will disappear for seemingly no reason. I am able to see code coverage information (the blue percentage bars for each class) in the Coverage tab of the reports navigator, but when I open any class in the editor, the coverage information does not appear along the right side of the window.Any ideas?Thank you!

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.

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

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.

Since installing iOS 14 on my iPhone, none of the AdMob ads in my apps are showing at all. I have watched, re-watched, and read all the documentation about AppTrackingTransparency and it is still not clear at all to me what to expect comes the launch of iOS 14. 1/ For ads to show in all my apps when iOS 14 launches to the public, do I have to update all of my apps for ads to keep showing? 2/ What happens if I do not update my apps before the iOS 14 public launch? Will ads be entirely prevented from showing at all? Or will the apps only show non-personalized ad? Thank you in advance.
