Do you have a question? If so, you will have to say what it is, and supply more information about your app, so that people can help you.

That (kinda) Worked! I think it did work, but you now move on to different questions! Also, why can't I just put objectWillChange.send() in the Data class? That will send objectWillChange for the data object, not for the NFCReader object (which is what ContentView is observing).

As a test, in NFCReader, after addItem(), try forcing the update by adding: objectWillChange.send()

You are using an Extension to add functionality to an existing class (UIViewController) that you don't "own". This is exactly what Extension is for. A fuller explanation: https://www.hackingwithswift.com/quick-start/understanding-swift/when-should-you-use-extensions-in-swift

The function cannot return the value retrieved by your dataTask, as the function returns before the dataTask finishes. The dataTask completion should set some value in the wider environment, or itself call a passed-in completion closure.

I tried that and it still does not seem to work Can you show your code?

In NFCReader, the "data" that you are adding the new item to is not the same as the "data" in your ContentView. They are two separate objects. So the addition will never show up in your UI. You need to use a single "data", and pass it to wherever it is needed. For example... In ContentView, you could remove data, make NFCReader the StateObject, publish NFCReader's data, and refer to that data in your View.

The sequence is: Ready for Review You submit it for Review Waiting for Review ...In Review... etc.

On iOS, it isn't the app that triggers the location update, it's the system. The update is then passed on to any app that is listening for that update. So in that sense, yes, if Google Maps receives a location update, your app can also receive it.

Consider this: struct PickColorView: View { @State private var number1: Int = 4 @State private var number2: Int = 0 let range: ClosedRange<Int> = 0...20 let array: Array<Int> = [14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60] var body: some View { NavigationView { Form { Picker(selection: $number1, label: Text("Number1")) { ForEach(range, id: \.self) { number in Text("\(number)") } } .onChange(of: number1) { newNumber1 in print("newNumber1: \(newNumber1)") } Picker(selection: $number2, label: Text("Number2")) { ForEach(array, id: \.self) { number in Text("\(number)") } } .onChange(of: number2) { newNumber2 in print("newNumber2: \(newNumber2)") } } .navigationBarTitle("Settings") .navigationBarHidden(false) } .navigationViewStyle(StackNavigationViewStyle()) } }

In Xcode, go to Target > Info Under Custom iOS Target Properties, add a new row, then: Type UIFileSharingEnabled, and press Return... ...it changes to "Application supports iTunes file sharing" Enter the value "YES"

I agree.

Is there a question here... embedded in this mass of text?

Yep. See Target > Info

It looks like it is not possible. But there is a possible workaround here: https://www.webdigi.co.uk/blog/2016/how-to-transfer-your-app-to-an-ios-simulator-on-another-machine-using-app-file-and-xcrun/ Is that any help?
