The ** values ** array is just a placeholder for now, it can be empty or have N elements, I just want to assign 0 to values[i] when it doesn't exists, but when I try it it crashes anyway

The problem is not the onTapGesture (the onTapGesture is also a placeholder), the problem is that valori has fewer elements than valoriAsseX, I want that if valori[I] doesn't exist it becomes 0. Don't look at the onTapGesture, it's not a problem

I don't think it's working. It still syncs the data across devices just if I close and reopen the app. I had also tried using a timer, to call the readData function every second, but it creates several bugs in the app.

Your code makes CloudKit work but stops the widget extension from connecting to the CoreData Database. Thank you for your time.

extension Date: RawRepresentable { public var rawValue: String { self.timeIntervalSinceReferenceDate.description } public init?(rawValue: String) { self = Date(timeIntervalSinceReferenceDate: Double(rawValue) ?? 0.0) } } This one works Thank you!

You should probably have to recreate the database completely, just keeping existing records. If you can explain better your solution it would be better for me In any case, does this cause you problem or is this for understanding ? It does not create me a direct problem, however I want to find a solution, because if you think about it, if you add and delete data every day for 100 days, even if there is no data (in the app) there will be a lot of MB occupied by the app in the iPhone Storage. Thank You!

And what if I wanted to write if Date() > Date() + 86400 for example, is it formatted?

let date = Calendar.current.dateComponents(in: .current, from: Date()).date! print(date)  Even if I do this it gives me the wrong date Why?

It works, Thank You OOPer!

Is there another way? Because this .onRecevie(books.publisher) repeats too many times, I want it to execute one time?

???

Does your actual code show the collapse button ? Yes Here is a very similar code struct ContentView: View { var body: some View { NavigationView{ List{ NavigationLink { Text("Hello") } label: { Text("Hello") } NavigationLink { Text("World") } label: { Text("World") } } .navigationTitle("Test") } } } What I want to really achieve is the sidebar that is used in the iPad Settings app, if you know how to do that, it would be perfect. Thank You very much

Why do you absolutely want to use predicate ? Because I Want to use it in @FetchRequest

Ok Thank You

I just solved it, I forgot to add App Groups, however the app isn't refreshing, to see the new data I have to close it and reopen it, any clue on how to fix this issue, I will post my CoreData Stack
