Overview

Microsoft did a very good job with UWP, when you build app for Windows Phone, those app automatically scales to big screen (horizontal oriented devices) Tablet, PC, Xbox. Kind of similar to website that have responsive UI. Eitherway, Apple needs to do something similar... there is no reason why phone apps are so small on my iMac. Even if it is already supported, Apple needs to encourage developers to implement it.

Hey, i just created and trained an MLImageClassifier via the MLImageclassifier.train() method (https://developer.apple.com/documentation/createml/mlimageclassifier/train(trainingdata:parameters:sessionparameters:)) For my Trainingdata (MLImageclassifier.DataSource) i am using my directoy structure, so i got an images folder with subfolders of person1, person2, person3 etc. which contain images of the labeled persons (https://developer.apple.com/documentation/createml/mlimageclassifier/datasource/labeleddirectories(at:)) I am saving the checkpoints and sessions in my appdirectory, so i can create an MLIMageClassifier from an exisiting MLSession and/or MLCheckpoint. My question is: is there any way to add new labels, optimally from my directoy strucutre, to an MLImageClassifier which i create from an existing MLCheckpoint/MLSession? So like adding a person4 and training my pretrained Classifier with only that person4. Or is it simply not possible and i have to train from the beginning everytime i want to add a new label? Unfortunately i cannot find anything in the API. Thanks!

I am woking on a project for a client and they have an individual apple developer account. They added me to their team as an admin sometime back but the team is still not showing up in Xcode. Only my personal team is visible. Is this because it's an Individual account? Any way to fix this? Appreciate your help.

can anyone tell me if this means that someone has been accessing my device through home kit. I've been going through my analytics data and I've been seeing a bunch of stuff that looks sketch or making me think someones been accessing my phone through over devices {"Count":3,"dataSyncState":"HMHomeManagerDataSyncStateGood","timeSinceLaunchToDataSyncStateGood":null,"timeSincePreviousProcessLaunch":null},"name":"HomeKitProcessLaunchInfo_GMEnabledView","sampling":100,"uuid":"8370926b-a296-4663-b3e1-7cce1e783fd7_2"}

Though I cannot find any documentation, it seems that UIPasteboard cannot be used from a Quick Look Preview app extension. I have such an extension, which contains a view that supports copying text as follows: - (IBAction)copy:(nullable id)sender { UIPasteboard * pboard = UIPasteboard.generalPasteboard; pboard.string = _rep.text; } This is invoked from a context menu (edit menu) item. This works fine In the simulator, but on device the pasteboard remains empty and errors like the following are emitted: -[PBServerConnection pasteboardWithName:createIfNeeded:authenticationBlock:dataOwnerBlock:error:] failed with error: Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service named com.apple.pasteboard.pasted was invalidated: failed at lookup with error 159 - Sandbox restriction." UserInfo={NSDebugDescription=The connection to service named com.apple.pasteboard.pasted was invalidated: failed at lookup with error 159 - Sandbox restriction.} It's unclear to me why such functionality would be problematic and necessary to block. It would be nice if this were documented clearly, as I wasted a lot of time trying to figure out why this was not working. (And no, I have not filed a feedback report or TSI yet, as I'm presently very short on time, and I don't have a sample project prepared to demonstrate the issue.)

Hi all, I ran into an XCUITest issue where my tests fail randomly with the message that my app "has not loaded accessibility" I run the tests in my scheme in random order and with every run, some other random test fails and a test that previously failed would later pass. So I know it's not my test as-such that is causing the problem. There seems to be a 60s wait for accessibility to load, and I have not found any information how I could extend the timeout or convince accessibility to load faster. I found some older posts, but no real solution was found there either. This completely blocks my test execution since I cannot get a single run in where the tests all pass (and I only have 10 tests in that scheme). I ran the scheme against an iOs sim and against a real iOS device and I get the same random accessibility errors on either execution platform. I've tried iOS17.2 & 17.4 and get the same behavior. Strange enough, the test actually keeps running (and technically passes all the checks and asserts in the actual test) after the accessibility error, but then XCTest marks it as failed because of the early accessibility error. Any ideas what I could try or what the reason could be? Thanks! -- I'm using XCode Version 15.3 (15E204a) and test iOS17.2 and iOS17.4 Test Case '-[MyScheme.MyTestClass testMyFunction]' started. t = 0.00s Start Test at 2024-04-19 01:32:09.225 t = 0.02s Set Up t = 0.02s Open com.myCompany.myApp t = 0.03s Launch com.myCompany.myApp t = 0.25s Wait for accessibility to load t = 60.30s Capturing diagnostic spindump /Users/some/path/goes/here/MyTestCase.swift:120: error: -[MyScheme.MyTestClass testMyFunction] : Application 'com.myCompany.myApp' has not loaded accessibility t = 60.34s Waiting 60.0s for "test" Button to exist t = 61.38s Checking `Expect predicate `exists == 1` for object "test" Button` t = 61.39s Checking existence of `"test" Button` ... more stuff happening in the test here ...

When using an ASWebAuthenticationSession to log in, with prefersEphemeralSession = false to enable SSO, the system presents an alert asking if the user wants to allow "SomeApp" to Sign In with "someauthprovider.xyz". The system presents exactly the same alert when you want to log out, and it is confusing for users. It's my understanding that the system does this because the alert really means "would you like to allow this app to let some page access Safari's shared cookie vault?" in lay terms, and is not distinguishing between create, read, update, or delete. It would be splendid if Apple changes this dialog depending on the operation. I would also like to know if there is any other way to fix this.

Hello, I'm working on developing an app for a client, whose core functionality includes the ability to share images. One of the specific features required is for users to be able to select a contact within our app and send an image directly to that contact's chat on WhatsApp, without going through the standard iOS Share Sheet. As far as I understand, iOS offers a great integration for sharing content through activity view. However, due to specific project requirements, we are exploring the possibility of sending images directly to a third party app (in this case, WhatsApp) without using activity view, initiating the attempt to share programmatically. Is it technically possible to implement this functionality under current iOS development guidelines? If possible, could you please guide me on which APIs or methods would be suitable to perform this action directly? Are there any special considerations or permissions we should take into account to implement this functionality without violating App Store regulations or third party terms of service such as WhatsApp?

Hi, I have a watchOS app that records audio for an extended period of time and because the mic is active, continues to record in background mode when the watch face is off. However, when a call comes in or Siri is activated, recording stops because of an audio interruption. Here is my code for setting up the session: private func setupAudioSession() { let audioSession = AVAudioSession.sharedInstance() do { try audioSession.setCategory(.playAndRecord, mode: .default, options: [.overrideMutedMicrophoneInterruption]) try audioSession.setActive(true, options: .notifyOthersOnDeactivation) } catch { print("Audio Session error: \(error)") } } Before this I register an interruption handler that holds a reference to my AudioEngine (which I start and stop each time recording is activated by the user): _audioInterruptionHandler = AudioInterruptionHandler(audioEngine: _audioEngine) And here is how this class implements recovery: fileprivate class AudioInterruptionHandler { private let _audioEngine: AVAudioEngine public init(audioEngine: AVAudioEngine) { _audioEngine = audioEngine // Listen to interrupt notifications NotificationCenter.default.addObserver(self, selector: #selector(handleAudioInterruption(notification:)), name: AVAudioSession.interruptionNotification, object: nil) } @objc private func handleAudioInterruption(notification: Notification) { guard let userInfo = notification.userInfo, let interruptionTypeRawValue = userInfo[AVAudioSessionInterruptionTypeKey] as? UInt, let interruptionType = AVAudioSession.InterruptionType(rawValue: interruptionTypeRawValue) else { return } switch interruptionType { case .began: print("[AudioInterruptionHandler] Interruption began") case .ended: print("[AudioInterruptionHandler] Interruption ended") print("Interruption ended") do { try AVAudioSession.sharedInstance().setActive(true) } catch { print("[AudioInterruptionHandler] Error resuming audio session: \(error.localizedDescription)") } default: print("[AudioInterruptionHandler] Unknown interruption: \(interruptionType.rawValue)") } } } Unfortunately, it fails with: Error resuming audio session: Session activation failed Is this even possible to do on watchOS? This code worked for me on iOS. Thank you, -- B.

I updated to 14.5 Beta today and the mouse no longer makes click sounds (yes I have double-checked the configs). Known issue maybe?

Hello, I have some networking code that checks whether a proxy is configured via: `CFStringRef host = (CFStringRef)CFDictionaryGetValue(globalSettings, kCFNetworkProxiesHTTPProxy);` `CFNumberRef port = (CFNumberRef)CFDictionaryGetValue(globalSettings, kCFNetworkProxiesHTTPPort);` I need to do this fairly frequently, so I am wondering if there is an announcer I can subscribe to instead?

I would like to be able to save files to the app's main document's directory from within a share sheet. Is this possible? Thanks, Rob

If put a List in ScrollVIew, List won't appear: import SwiftUI struct BugView: View { let numbers: [Int] = [0, 1, 2] var body: some View { ScrollView { List(numbers, id: \.self) { number in Text(number.description) } } } } #Preview { BugView() }

(Copied from https://github.com/google/jax/issues/20835) I am attempting to use JAX on Metal (on a M1 Pro chip) to model discrete (count) data. I've installed the latest version jax-metal 0.0.6 using pip. The installation seems to have worked overall as I can perform basic Jax array operations on GPU. However, when I try to compute the (log-)PMFs/PDFs of random variables which are defined in terms of the (log-)Gamma function I get errors like the one below which seems to indicate that the lax.lgamma function is not supported under the hood on M1 metal. This is essential functionality for a wide class of probabilistic machine learning models.

Summary: Need help with Certificates, Identifiers and Profiles settings to allow two apps to use Sign in with Apple. Background: We have a web application (React, static JavaScript) that allows users to sign in with Apple, Google or Microsoft via OAuth/OIDC. We are developing a mobile application using React Native and Expo. Both the web application and the mobile application use the same backend (Django). For the mobile application, we added Google and Microsoft sign in via the same web-based OAuth/OIDC flow. For Sign in with Apple, we are using the expo-apple-authentication package to get the required native sign in experience. We have two active app identifiers: org.terraso.terraso; web app; primary Apple ID org.terraso.test.Terraso-LandPKS; mobile apple; Group with an existing primary App ID (selected (1), the web app) We have one services identifier: org.terraso.app; primary ID is web app (app identifier 1) above; URLs have been configured We have one app group: group.org.terraso (seems unused) On our backend app, we have code: https://github.com/techmatters/terraso-backend/blob/abc655e83eaca849e2bc24389946cc4f0bcd9d48/terraso_backend/apps/auth/providers.py#L84 and APPLE_CLIENT_ID is set to org.terraso.app (which matches the services identifier above In my local development environment, I have tried a few different combinations of IDs attempting to get this to work using the iOS simulator: (i) backend client id: org.terraso.app mobile app bundle Id: org.terraso.test.Terraso-LandPKS result: error: jwt.exceptions.InvalidAudienceError: Audience doesn't match (ii) backend: org.terraso.app mobile app: org.terraso.app result: clicking "Sign In" in Apple ID dialog is a no-op (no errors from client or server) (iii) backend: org.terraso.test.Terraso-LandPKS mobile app: org.terraso.test.Terraso-LandPKS result: works (but I can't use that in production, because the client ID is wrong) How can I configure Sign in with Apple to allow both the web app, the mobile app (and possible additional mobile apps) to work with the same backend? Do I need to us app groups? When do you use app groups vs "group with an existing primary apple id"?

We develop an iOS SDK that allows developers to add VoIP capability to their iOS applications. For post-call quality analysis and debugging purposes we do collect SDK API usage and call quality data and send them back through internal HTTP API endpoint, therefore we need to disclose the domain in the privacy manifest. However we do not collect any Personally Identifiable Information and definitely have no intent to use these data for tracking the users like the examples described in https://developer.apple.com/app-store/user-privacy-and-data-use/. Our question is, do we need to set the “NSPrivacyTracking” key to “true” in the privacy, or our SDK actually is not tracking from the Privacy Manifest’s perspective and simply disclosing the data collection type/purpose as well as the domain is sufficient?

I have a simple example to demonstrate... struct MyView: View { var body: some View { Text("WOW") } } struct MyOtherView: View { var body: some View { NavigationStack { Text("WOW") } } } On VisionOS, MyOtherView has a glass background effect that cannot be disabled. glassBackgroundEffect(displayMode: .never) .background(.clear), .foregroundColor(.clear), none of them work. I then resorted to the SwiftUIIntrospect package to try set .clear on various child objects of the NavigationStack but nothing is working. I am in control of my own glass containers. I have a couple with space between them, but with the NavigationStack it sets a background behind both of them ruining the effect. This is what MyOtherView renders as: I'm looking for it to be completely transparent except the text. Like the below layout. For now I will have to roll my own navigation.

In my SwiftUI view, I try to load the image from data. var body: some View { Group{ if let data = model.detailImageData, let uiimage = UIImage(data: data) {// no memory issue Image(uiImage: uiimage) .resizable() .scaledToFit() } } } But I want to get the HDR style of my image, so I use if let data = model.detailImageData, let uiimage = UIImageReader.default.image(data:data){ //memory leaks!!! When I change the data, the memory of the previous image is never freeed. finally caused my app to crash. You can see it from the Instrument screenshot.
