I have an existing iOS app with MapKit. It always shows the current user location with UserAnnotation. But the same isn't true for macOS. I have this sample macOS application in SwiftUI. In the following, the current user location with a large blue dot appears only occasionally. It won't, 19 of 20 times. Why is that? I do have a location privacy key in Info.plist. And the Location checkbox is on under Signing & Capabilities. import SwiftUI import MapKit struct ContentView: View { @State private var markerItems: [MarkerItem] = [ MarkerItem(name: "Farmers Market 1", lat: 35.681, lon: 139.691), MarkerItem(name: "Farmers Market 2", lat: 35.685, lon: 139.695), MarkerItem(name: "Farmers Market 3", lat: 35.689, lon: 139.699) ] @State private var position: MapCameraPosition = .automatic var body: some View { Map(position: $position) { UserAnnotation() ForEach(markerItems, id: \.self) { item in Marker(item.name, coordinate: CLLocationCoordinate2D(latitude: item.lat, longitude: item.lon)) } } .mapControlVisibility(.hidden) .mapStyle(.standard(elevation: .realistic)) .ignoresSafeArea() } } #Preview { ContentView() } struct MarkerItem: Hashable { let name: String let lat: Double let lon: Double }

I have a desktop application that shows some real estate properties chosen by the user. The application shows those GPP locations on the map. The SwiftUI code is something like the following. import SwiftUI import MapKit struct ContentView: View { var body: some View ZStack { mapView } } private var mapView: some View { Map(position: $propertyViewModel.mapPosition) { ForEach(propertyViewModel.properties) { property in Annotation("", coordinate: CLLocationCoordinate2D(latitude: property.lat, longitude: property.lon)) { Button { } label: { VStack { Image(systemName: "house.circle.fill") .resizable() .scaledToFit() .frame(width: 48) .foregroundStyle(colorScheme == .light ? .white : .black) ... } } .buttonStyle(.borderless) } } UserAnnotation() } .mapControls { MapUserLocationButton() } .mapControlVisibility(.visible) .onAppear { CLLocationManager().requestWhenInUseAuthorization() } } } The application only wants to use the CLLocationManager class so that it can show those locations on the map relative to your current GPS position. And I'm hit with two review rejections. Guideline 5.1.1 - Legal - Privacy - Data Collection and Storage Issue Description One or more purpose strings in the app do not sufficiently explain the use of protected resources. Purpose strings must clearly and completely describe the app's use of data and, in most cases, provide an example of how the data will be used. Guideline 5.1.5 - Legal - Privacy - Location Services The app uses location data for features that are not relevant to a user's location. Specifically, the app is not functional when Location Services are disabled. So I wonder if the application is even required to have 'NSLocationWhenInUseUsageDescription' and/or 'NSLocationUsageDescription'? just in order to show user's current location so that they can see property locations relative to it? The exact location privacy statement is the following. The application needs your permission in accessing your current location so that it will appear on the map

I have a desktop application developed in SwiftUI that shows property locations on the map. That's NOT the main feature. IF you give the application permission to access your location, the blue dot will appear on the map. If you don't, the blue user dot won't appear. That's the only difference with location services. In other words, the application has no use of user's current position beyond showing it on the map. Since it's just the matter of showing or not showing the blue dot on the map, the application doesn't really need to use the location service. Anyway, the reviewer is talking about something else by rejecting the application in two aspects. Guideline 5.1.1 - Legal - Privacy - Data Collection and Storage Guideline 5.1.5 - Legal - Privacy - Location Services As I said earlier, the application only wants to show the blue dot on the map so that you can see your property locations relative to your current location. In code, it's something like the following. Map(position: $propertyViewModel.mapPosition) { ForEach(propertyViewModel.properties) { property in Annotation("", coordinate: CLLocationCoordinate2D(latitude: property.lat, longitude: property.lon)) { ... } } UserAnnotation() } So I'm hit with two rejection reasons with this one line. UserAnnotation() And the reviewer is talking about something like the app is not functional when Location Services are disabled. To resolve this issue, please revise the app so that the app is fully functional without requiring the user to enable Location Services. Well, I can remove the UserAnnotation() line if I want to put this application through the review process. Nothing will become dysfunctional, though, if you decide to reject permission request. So would you remove it or would you play along with this reviewer if you were me? It's been three or four days since rejection. As you can imagine, the reviewer doesn't bother to answer as to What are the exact coordinates that the application has allegedly collected What won't work as a result of location permission request refusal. This isn't the first time I get my app rejected. I've probably had 150 to 200 of them rejected in the past 15 years. And just because a reviewer rejects your app for a bizarre reason, would you give in? Remove this feature and that feature because the reviewer is incompetent such that he or she makes his or her decision based on imagination? What do you think?

I have several macOS applications that use CloudKit. I need to test and finds out what happens when the user signs out of their iCloud account. That's because the application may lose data after signing out and then signing in again. Every time I do that, it'll take 15, 20 minutes... I don't time it, but it takes quite a gigantic time to sign out as the spinner keeps rolling. Why does it take so long to just sign out? This sign out effect is untestable because it takes a long time to sign out of an iCloud account and then make changes to the code and then test again. In case you need to know, my system version is Sequoia 15.7.

Am I the only one wasting my time having preview videos processed? I've been waiting for hours. I wasted an hour just trying to sign out of an iCloud account yesterday. Now this process is taking a big chunk of my valuable time. Pardon me for saying it, Apple, Inc. But this is stupid and so unproductive.

I submitted a software update for one iOS app several days ago. It was approved two days ago. I received a message about distribution that said The status of your app has changed to Ready for Distribution I happened at the iTunes Connect website at that very moment in order to submit a totally new iOS app to the App Store. Its status said 'Removed from App Store.' I thought it was a rare mistake. Unfortunately, it's not. The one that I was submitting was approved some 15 minutes ago. I received the 'Ready for Distribution' message by email. Yet, it's been removed from the store as you see in the screenshot below. As you see in the 2nd screenshot below, it says that it's Ready for Distribution. But it's not? So is this a new norm? And we have to go back the iTunes Connect website to change the app status every time we submit a software title and then get it approved?

Hello. I'm a little bit confused about how TestFlight works. If I have an iOS app under development that has not been in the store and that has not been submitted for a review yet, can I use TestFlight to have it tested by my development team? I know that there are two types of tests, internal tests and external tests. It seems that you can use TestFlight for internal tests even if the app has not been submitted for a review. Thanks.

I have the following lines of code in practicing Combine. import UIKit import Combine class ViewController: UIViewController { // MARK: - Variables var cancellable: AnyCancellable? @Published var segmentNumber: Int = 0 // MARK: - IBOutlet @IBOutlet weak var actionButton: UIButton! // MARK: - IBAction @IBAction func segmentChanged(_ sender: UISegmentedControl) { segmentNumber = sender.selectedSegmentIndex } // MARK: - Life cycle override func viewDidLoad() { super.viewDidLoad() cancellable = $segmentNumber.receive(on: DispatchQueue.main) .assign(to: \.isEnabled, on: actionButton) } } I get an error at .assign that says Value of type 'UIView?' has no member 'isEnabled' What am I doing wrong? Thank you.

I'm trying to understand how Combine works. The following is my sample code. import UIKit import Combine class ViewController: UIViewController { // MARK: - Variables var cancellable: AnyCancellable? // MARK: - IBAction @IBAction func buttonTapped(_ sender: UIButton) { currentValueSubject.send(20) } // MARK: - Life cycle var currentValueSubject = CurrentValueSubject<Int, Never>(1) override func viewDidLoad() { super.viewDidLoad() let cancellable = currentValueSubject .sink { value in print("New value: \(value)") } currentValueSubject.send(5) currentValueSubject.send(10) //currentValueSubject.send(completion: .finished) currentValueSubject.send(15) //cancellable.cancel() } } If I run it with the iPhone simulator, I get New value: 1 New value: 5 New value: 10 New value: 15 If I tap the button, the app won't get a new value. I suppose that's because the subscription is cancelled at the end of viewDidLoad? If so, why does it get cancelled? I don't quite see a practical side of Combine's Subject. When is it useful? Thanks.

I just want to show a simple navigation title like the following. import SwiftUI struct ContentView: View { var body: some View { NavigationView { ZStack { Color.red.edgesIgnoringSafeArea(.all) Text("Hello") } .navigationTitle("GGG") .navigationBarTitleDisplayMode(.inline) .navigationBarHidden(false) } } } And I get a bunch of mumbo jumbo auto-layout warnings (Unable to simultaneously satisfy constraints...) in Console. If I comment out the navigationTitle line, I won't get them. I have never seen those messages in showing a navigation title when writing code with UIKit. What am I doing wrong? Muchos thankos

I have the following lines of code to work with a list of strings. import SwiftUI struct ContentView: View { @State private var users = ["George", "Kenny", "Susan", "Natalie"] var body: some View { NavigationView { List { ForEach(users, id: \.self) { user in Text(user) } .onDelete(perform: delete) } .navigationBarTitle("My family") .toolbar { EditButton() } } } func delete(at offsets: IndexSet) { users.remove(atOffsets: offsets) } } Now, I'm doing the following out of curiosity. Now, I have a button in naviationBarItems. And I wonder if I can turn on and off the edit feature of the list with the button? struct ContentView: View { @State private var users = ["George", "Kenny", "Susan", "Natalie"] var body: some View { NavigationView { List { ForEach(users, id: \.self) { user in Text(user) } } .navigationBarTitle("My family") .navigationBarItems(trailing: Button(action: { print("Edit button pressed...") }) { Text("Edit") } ) } } } Muchos thankos.

I have the following lines of code for showing a list of friends. import SwiftUI struct ContentView: View { @State var users = ["Susan", "Kate", "Natalie", "Kimberly", "Taylor", "Sarah", "Nancy", "Katherine", "Nicole", "Linda", "Jane", "Mary", "Olivia", "Barbara"] @State var editMode = EditMode.inactive var body: some View { NavigationView { List { ForEach(users, id: \.self) { user in Text(user) } } .navigationBarTitle("Friends") .environment(\.editMode, $editMode) .navigationBarItems(leading: Button("Edit", action: { if self.editMode == .active { self.editMode = .inactive } else { self.editMode = .active } })) } } } If you see the code at the bottom, I have four lines just in order to change the value of editMode. Does SwiftUI have something like showDetails.toggle() where showDetails is a Boolean variable? Muchos thankos.

I have the following simple lines of code. import SwiftUI struct ContentView: View { var users = ["Susan", "Kate", "Natalie", "Kimberly", "Taylor", "Sarah", "Nancy", "Katherine", "Nicole", "Linda", "Jane", "Mary", "Olivia", "Barbara"] var body: some View { List { ForEach(users, id: \.self) { user in Text(user) } } } } So I'm just listing names. What I want to ask is what is id and what .self means. If I look up the doc under ForEach, it says the following. Either the collection’s elements must conform to Identifiable or you need to provide an id parameter to the ForEachinitializer. Does the compiler automatically generate a unique string like UUID for each element in the array or something? Can I somehow print the raw value of each id? Muchos thankos.

Hola, I have the following simple lines of code. import UIKit import Combine class ViewController: UIViewController { // MARK: - Variables var cancellable: AnyCancellable? @Published var labelValue: String? // MARK: - IBOutlet @IBOutlet weak var textLabel: UILabel! // MARK: - IBAction @IBAction func actionTapped(_ sender: UIButton) { labelValue = "Jim is missing" } // MARK: - Life cycle override func viewDidLoad() { super.viewDidLoad() cancellable = $labelValue .receive(on: DispatchQueue.main) .assign(to: \.text, on: textLabel) } } I just wonder what is the point of specifying the main thread with .receive? If I comment out the receive line, the app will still run without a problem. Muchos thankos

Let me say that I have an IBOutlet object like @IBOutlet weak var deleteButton: UIButton! RxCocoa can make this button tap observable like deleteButton.rx.tap It doesn't look like Combine lets us observe a button tap. Am I right? I find one approach found at the following URL. https://www.avanderlee.com/swift/custom-combine-publisher/ And Combine has no native approach? And you still have to use the IBAction?
