DTiPhoneSimulatorErrorDomain Code 2

I have something like this drawing in an MTKView (see at bottom). I am finding it difficult to figure out when can the Swift-land resources used in making the MTLBuffer(s) be released? Below, for example, is it ok if args goes out of scope (or is otherwise deallocated) at point 1, 2, or 3? Or perhaps even earlier, as soon as argsBuffer has been created? I have been reading through various articles such as Setting resource storage modes Choosing a resource storage mode for Apple GPUs Copying data to a private resource but it's a lot to absorb and I haven't been really able to find an authoritative description of the required lifetime of the resources in CPU land. I should mention that this is Metal 4 code. In previous versions of Metal, the MTLCommandBuffer had the ability to add a completion handler to be called by the GPU after it has finished running the commands in the buffer but in Metal 4 there is no such thing (it it were even needed for the purpose I am interested in). Any advice and/

Hello, I’m reaching out after several days of investigation, as I’ve exhausted all standard troubleshooting steps and would truly appreciate guidance from Apple engineers or experienced developers. I am experiencing a persistent issue where StoreKit does not return any subscription products on any device, despite all subscriptions being fully approved and correctly configured in App Store Connect. What is happening • Auto-renewable subscriptions exist and are approved in App Store Connect • The app is installed from the production App Store (not TestFlight, not sandbox) • initConnection / StoreKit initialization succeeds • Requests for products/subscriptions return an empty result (no errors, no IDs) • In the UI, prices are shown as “Unavailable” • This behavior is 100% reproducible on every device, every Apple ID, every network Important detail This issue is not device-specific, account-specific, or environment-specific: • Tested on multiple iPhones • Tested with different Apple IDs • Tested on different net

Hello, we are using DeviceCheck – App Attest in a production iOS app. The integration has been live for some time and works correctly for most users, but a small subset of users encounter non-deterministic failures that we are unable to reproduce internally. Environment iOS 14+ Real devices only (no simulator) App Attest capability enabled Correct App ID, Team ID and App Attest entitlement Production environment Relevant code let service = DCAppAttestService.shared service.generateKey { keyId, error in // key generation } service.attestKey(keyId, clientDataHash: hash) { attestation, error in // ERROR: com.apple.devicecheck.error 3 / 4 } service.generateAssertion(keyId, clientDataHash: clientDataHash) { assertion, error in // ERROR: com.apple.devicecheck.error 3 / 4 } For some users we intermittently receive: com.apple.devicecheck.error error 3 com.apple.devicecheck.error error 4 Characteristics: appears random affects only some users/devices sometimes resolves after time or reinstall not reproducible

Since updating to tvoS 26.1/2 YouTube audio breaks when playing videos at anything other than 1x speed. At 1.25x or higher, the audio is static-y and distorted almost immediately. Strangely, AirPods work fine, it only happens with other audio outputs. Anyone else experiencing this, or have a fix? tvOS: 26.2 (23J582) YouTube app: 4.51.08 Speed Output Static 1x TV speakers No 1x HomePods No 1x AirPods Pro 3 No 1.25x TV speakers Yes 1.25x HomePods Yes 1.25x HomePods Mini Yes 1.25x Sonos One Yes 1.25x AirPods Pro 3 No

I've spent a few months writing an app that uses SwiftData with inheritance. Everything worked well until I tried adding CloudKit support. To do so, I had to make all relationships optional, which exposed what appears to be a bug. Note that this isn't a CloudKit issue -- it happens even when CloudKit is disabled -- but it's due to the requirement for optional relationships. In the code below, I get the following error on the second call to modelContext.save() when the button is clicked: Could not cast value of type 'SwiftData.PersistentIdentifier' (0x1ef510b68) to 'SimplePersistenceIdentifierTest.Computer' (0x1025884e0). I was surprised to find zero hit when Googling Could not cast value of type 'SwiftData.PersistentIdentifier'. Some things to note: Calling teacher.computers?.append(computer) instead of computer.teacher = teacher results in the same error. It only happens when Teacher inherits Person. It only happens if modelContext.save() is called both times. It works if the first modelContext.save

Hi, Its been well over 2 weeks I applied for the small business program ( Apple takes 15% instead of 30% when < $1M in sales ) and I still did not receive any response. Is it normal or should I contact them ? Thanks

I am using the xcrun notarytool submit --apple-id xxxxx@gmail.com --password xxxxx--team-id xxxxxx --output-format json --wait --no-progress /my/dmg/file to notarize my DMG file. But it always gives me back the error, Error: HTTP status code: 403. A required agreement is missing or has expired. This request requires an in-effect agreement that has not been signed or has expired. Ensure your team has signed the necessary legal agreements and that they are not expired. I did log in my developer account and found no place to sign any agreement. Actually in the morning when I logged in the developer account, it indeed pop up the agreement for me to sign and I did sign it. But now it seems I don't have any more agreements to sign. So, any ideas about what I should do?

I am trying to use the UIButtonConfiguration to set the UI state for the button.isEnabled status. I do see the ConfigurationUpdateHandler code below being executed but when the button.isEnabled is set to false, the UI does not reflect the updated backgroundColor. Instead it is a very light gray but the foregroundColor/text is being updated. It seems that the default disabled button treatment is being used despite being set to a different color. Is there a better way to suppress the default UIButton disabled state so I can customize? [newButton setConfigurationUpdateHandler:^(__kindof UIButton * _Nonnull button) { UIButtonConfiguration *updatedConfiguration; if (newButton.configuration != nil) { updatedConfiguration = newButton.configuration; if (button.isEnabled) { updatedConfiguration.baseBackgroundColor = [UIColor darkGrayColor]; updatedConfiguration.baseForegroundColor = [UIColor whiteColor]; } else { updatedConfiguration.baseBackgroundColor = [UIColor greenColor]; updatedConfiguration.baseForegro

Hi, we were recently approved for the com.apple.developer.web-browser.public-key-credential entitlement and have added it to our app. It initially worked as expected for a couple of days, but then it stopped working. We're now seeing the same error as before adding the entitlement: Told not to present authorization sheet: Error Domain=com.apple.AuthenticationServicesCore.AuthorizationError Code=1 (null) ASAuthorizationController credential request failed with error: Error Domain=com.apple.AuthenticationServices.AuthorizationError Code=1004 (null) Do you have any insights into what might be causing this issue? Thank you!

My app lets you create images with Image Playground. When the user approves an image I move it to the documents dir from the temp storage. With over a year of usage I’ve created a lot of images over time. Out of nowhere the app stopped loading my custom creations from Image Playground saying it couldn’t find the files. It still had my VoiceOver strings I had added for each image and still had the custom categories I assigned them. Debug code to look in the docs dir doesn’t find them. I downloaded the app’s container and only see the images I created as a test after the problem started. But my ~70MB app is still taking up 300MB on my iPhone so it feels like they’re there but not accessible. Is there anything else I can try?
