Overview

Our app exports a number of file types in info.plist. For each of these file types, we export various possible file name extensions. For example, for one of our file types, we specify the possible extensions ".data", ".fitdat", and ".profitdata". In the settings of our app, we allow the user to select their preferred extension to be used, i.e. the extension to be used when, e.g., saving a document with "Save As..." panel without explicitly specifying the extension. For this, we override NSDocument's fileNameExtensionForType:saveOperation to return the presently preferred extension. This has stopped working, probably starting from macOS 14. If the user does not specify the extension in the NSSavePanel, it's always the first extension (".data") that gets added to the file name. I guess it's a consequence of the introduction of UTType, which has its own preferredFilenameExtension, which in turn probably just grabs the first extension we specify in our info.plist Any advice how to resolve this? Is there any way to override NSSavePanel's selection of extension if the user does not specify one? Thanks for any advice in advance Kurt

Hi, I developped an app which is an alcohol level calculator (cf image for few screens). I did lots of modification to the app is accepted, but none works. I also asked to the verification team, but they can't help me more. However similar app already exists like https://apps.apple.com/fr/app/alcootel-by-maaf/id6444157056 or https://apps.apple.com/fr/app/%C3%A9thylom%C3%A8tre/id688242393. I even copy the description of the first app. So, could you help me about what I can change in order to the app is validated, or do the new rules make my app "out of the Apple laws". Thank you

Hi Team, If we release our app for Phase release after 2 days we have paused the app. What will happen if we not resume the app for more than 30 days?

I have tried to insert 1L key-values into the user defaults. It is working fine until 50k key-values. After some time, am getting Not updating lastKnownShmemState in CFPrefsPlistSource<0x2825b0c60> (Domain: peformance_validator, User: kCFPreferencesCurrentUser, ByHost: No, Container: (null), Contents Need Refresh: No) also, key-values are not updating in the plist as well. peformance_validator is my user defaults group name. How can I solve this ?

Hi Team, If we release our app for Phase release after 2 days we have pause the app. What will happen if we not resume the app for more than 30 days?

So, a bit of a complex situation. My device is an iPhone 15 Pro. Basically, this person is a contact on my phone, and she has blocked my phone number. However, my Apple ID email is not blocked. When I text this number on my iPad from the Apple ID, the message delivers and is Read. All normal so far. My question here is: On my iPhone 15, when I select "START NEW CONVERSATION FROM" and enable my Apple ID .. Will iMessage merge the prior text conversation initiated using my phone number (which is now blocked), or how will it handle these 2 threads (one from my phone number, the other the Apple ID)? She won't unblock, but she responds to my Apple ID email on iMessages. My goal here is to be able to receive and respond using my Apple ID on my phone, but I have a prior text conversation with this Contact on my Phone. Thanks!

NSString *jsonString = @"{\"key1\":\"value1\",\"key2\":\"value2\",\"key3\":\"value3\",\"key4\":\"value4\"}"; NSString *jsonString2 = @"{\"key2\":\"value2\",\"key1\":\"value1\",\"key4\":\"value4\",\"key3\":\"value3\"}"; NSData *jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding]; NSData *jsonData2 = [jsonString2 dataUsingEncoding:NSUTF8StringEncoding]; NSDictionary *dict1 = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers error:nil]; NSDictionary *dict2 = [NSJSONSerialization JSONObjectWithData:jsonData2 options:NSJSONReadingMutableContainers error:nil]; The expected results are： dict1:key1,key2,key3,key4 dict2:key2,key1,key4,key3 Is there any way to make that happen?

Hi All, I have a strange issue. I am using enableBackgroundDelivery for updating user step count in background mode using health kit. It works fine when I execute the app by pressing 'Run' in xcode. But the code is not triggering when I am directly launching it on my device. I have tried many different things but cannot figure out the issue from 2 days 😭. I would really appreciate any suggestions. Thanks

I have old ScreenCaptureKit sample downloaded on Oct 2022. That sample worked on Oct 2022. But it does not work on Apr 2024 on Sonoma 14.4.1 M1 MacBook. It only shows black screen. I also download updated ScreenCaptureKit sample and test it. It works on Sonoma 14.4.1 M1 MacBook. I noticed latest sample have SCContentSharingPicker and other changes. I have my screen capture application based on old ScreenCaptureKit sample. My app only shows black screen. Do I have to add SCContentSharingPicker and SCContentSharingPickerObserver on my application for capturing screen on Sonoma? Old way of screen capture without SCContentSharingPicker is not supported anymore on Sonoma?

I'm using CoreData+CloudKit. It works fine in development, so I deployed to production. But I cannot see the data in CloudKit DataBase in a testflight version. I don't know where I missed. Can I just run in Release mode to check it works?

I am currently writing an app that is about writing stories. As of now, it is fairly simple: ContentView is your "Collection" of stories. PopupView is when you click on a button in ContentView. In popup view you enter the story title. Once you do that, you are brought to a blank page which is StoryView, where the NavigationTitle is what your story title is. Once I finish the story and leave the page / StoryView, it is still there, but once I close the app on my phone and reopen it, the story is gone and is not saved. I am a relatively new developer, so ive been relying on ChatGPT and Google Gemini for the saving parts of this, but it rarely works, and the furthest ive gotten with it is that it saves the story title but doesn't save the content of the story. I have a feeling that the AI is overdoing it as well. If anyone could help, please do so. Ive been trying to fix this for days. If you need me to provide any code, I am happy to do so.

hi, in the settings in the application settings, how do I put a button there to allow the use of the camera?

In this code, I aim to enable users to select an image from their phone gallery and display it with less opacity on top of the z-index. The selected image should appear on top of the user's phone camera feed, allowing them to see the canvas on which they are drawing as well as the low-opacity image. The app's purpose is to enable users to trace an image on the canvas while simultaneously seeing the camera feed. CameraView.swift import SwiftUI import AVFoundation struct CameraView: View { let selectedImage: UIImage var body: some View { ZStack { CameraPreview() Image(uiImage: selectedImage) .resizable() .aspectRatio(contentMode: .fill) .opacity(0.5) // Adjust the opacity as needed .edgesIgnoringSafeArea(.all) } } } struct CameraPreview: UIViewRepresentable { func makeUIView(context: Context) -> UIView { let cameraPreview = CameraPreviewView() return cameraPreview } func updateUIView(_ uiView: UIView, context: Context) {} } class CameraPreviewView: UIView { private let captureSession = AVCaptureSession() override init(frame: CGRect) { super.init(frame: frame) setupCamera() } required init?(coder: NSCoder) { fatalError("init(coder:) has not been implemented") } private func setupCamera() { guard let backCamera = AVCaptureDevice.default(for: .video) else { print("Unable to access camera") return } do { let input = try AVCaptureDeviceInput(device: backCamera) if captureSession.canAddInput(input) { captureSession.addInput(input) let previewLayer = AVCaptureVideoPreviewLayer(session: captureSession) previewLayer.videoGravity = .resizeAspectFill previewLayer.frame = bounds layer.addSublayer(previewLayer) captureSession.startRunning() } } catch { print("Error setting up camera input:", error.localizedDescription) } } } Thanks for helping and your time.

I have an iPhone app that was created in Xcode that downloads some data from Google Firebase (Firestore). Today I got a scary email from Google Firebase (as seen on the screenshot below). I'm not an expert on Google Firebase and honestly don't understand what this means. Two questions: Does this mean our database is publicly available on the surface web (so for example search engines can crawl/index it)? What do I do about this? Extremely thankful for any help!

Please run the following UIKit app. It uses a collection view with compositional layout (list layout) and a diffable data source. It has one section with one row. The cell has an image view as a leading accessory. Unfortunately, as soon as I set an image for the image view, the accessory is no longer centered: import UIKit class ViewController: UIViewController { var collectionView: UICollectionView! var dataSource: UICollectionViewDiffableDataSource<String, String>! override func viewDidLoad() { super.viewDidLoad() configureHierarchy() configureDataSource() } func configureHierarchy() { collectionView = .init(frame: .zero, collectionViewLayout: createLayout()) view.addSubview(collectionView) collectionView.frame = view.bounds } func createLayout() -> UICollectionViewLayout { UICollectionViewCompositionalLayout { section, layoutEnvironment in let config = UICollectionLayoutListConfiguration(appearance: .insetGrouped) return NSCollectionLayoutSection.list(using: config, layoutEnvironment: layoutEnvironment) } } func configureDataSource() { let cellRegistration = UICollectionView.CellRegistration<UICollectionViewListCell, String> { cell, indexPath, itemIdentifier in let iv = UIImageView() iv.backgroundColor = .systemRed // iv.image = .init(systemName: "camera") iv.contentMode = .scaleAspectFit iv.frame.size = .init( width: 40, height: 40 ) cell.accessories = [.customView(configuration: .init( customView: iv, placement: .leading(), reservedLayoutWidth: .actual, maintainsFixedSize: true ))] } dataSource = .init(collectionView: collectionView) { collectionView, indexPath, itemIdentifier in collectionView.dequeueConfiguredReusableCell(using: cellRegistration, for: indexPath, item: itemIdentifier) } var snapshot = NSDiffableDataSourceSnapshot<String, String>() snapshot.appendSections(["main"]) snapshot.appendItems(["demo"]) dataSource.apply(snapshot, animatingDifferences: false) } } This seems like a bug but then if I set the image view's size to 100x100, even without giving it an image, the cell doesn't resize, which makes me think I'm making a mistake.
