The expirationHandler on BGProcessingTask is a () -> Void closure. It provides no information about why it was called. In my testing, all of the following trigger the same handler: Time expiration Resource pressure (CPU, memory, battery) Not reporting progress User tapping Stop on the Live Activity There is no way for the app to tell these apart. Questions: Q1. Is there an official, complete list of all conditions that trigger expirationHandler? The documentation only mentions time expires. Q2. What is the specific time limit before timeout? If it varies by device state, what are the conditions? Q3. A way to distinguish the reason is needed. User stop and system expiration require completely different handling. Currently this is impossible. Environment: iOS 26, physical device

Device: iPhone 17 Pro Max iOS version: iOS 26.3 CarPlay type: Wired We are encountering two intermittent UI issues in CarPlay when running our music application. The problems occur occasionally and cannot be recovered without restarting the device. Issue 1: CPListImageRowItem image not displaying On the CarPlay home page, some images occasionally fail to appear. Implementation details: The list is updated using CPListTemplate.updateSections. Each item is a CPListImageRowItem. On iOS versions below 26, images are updated using updateImages. On iOS 26, images are provided through CPListImageRowItem.elements, where each element is a CPListImageRowItemRowElement. Observed behavior: Logs confirm that the data is correctly provided. However, in failing cases the CPListImageRowItemRowElement appears with both title and subtitle equal to nil. The image is not rendered in the UI even though the item exists. Issue 2: Now Playing bottom buttons occasionally missing On the Now Playing

Among Japanese end users, audio issues during screen recording—primarily in game applications—have become a topic of discussion. We have confirmed that the trigger for this issue is highly likely to be related to changes to IOBufferDuration. When using setPreferredIOBufferDuration and the IOBufferDuration is set to a value smaller than the default, audio problems occur in the recorded screen capture video. Audio playback is performed using AudioUnit (RemoteIO). https://developer.apple.com/documentation/avfaudio/avaudiosession/setpreferrediobufferduration(_:)?language=objc This issue was not observed on iOS 18, and it appears to have started occurring after upgrading to iOS 26. We provide an audio middleware solution, and we had incorporated changes to IOBufferDuration into our product to achieve low-latency audio playback. As a result, developers using our product as well as their end users are being affected by this issue. We kindly request that this issue be investigated and addressed in a

Given that we can't use isEligibleForAgeFeatures property on macOS, the documentation states that In macOS, isEligibleForAgeFeatures returns false because the system doesn’t require Age Assurance for the person or device. However, you can still call requestAgeRange in macOS to get the declared age range. But in unsuitable region the requestAgeRange request always returns DeclaredAgeRange.AgeRangeService.Error.notAvailable which is vague, as it might stand for API being unavailable just as well as You receive this error when the system prompts a person and they decide not to share their age range with your app. , as per documentation. Unfortunately, this error fires immediately instead of showing any kind of prompt for user, so the description is definitely wrong (or incomplete) in here. Possible solutions: expand Error cases to separate not available API and not available response expand isEligibleForAgeFeatures to properly support macOS Moreover, unlike iOS, there is still no usable tool or algorith

I'm implementing a PHBackgroundResourceUploadExtension to back up photos and videos from the user's library to our cloud storage service. Our existing upload infrastructure uses chunked uploads for large files (splitting videos into smaller byte ranges and uploading each chunk separately). This approach: Allows resumable uploads if interrupted Stays within server-side request size limits Provides granular progress tracking Looking at the PHAssetResourceUploadJobChangeRequest.createJob(destination:resource:) API, I don't see a way to specify byte ranges or create multiple jobs for chunks of the same resource. Questions: Does the system handle large files (1GB+) automatically under the hood, or is there a recommended maximum file size for a single upload job? Is there a supported pattern for chunked/resumable uploads, or should the destination URL endpoint handle the entire file in one request? If our server requires chunked uploads (e.g., BITS protocol with CreateSession → Fragment → CloseSession), is this ext

I am requesting a dedicated toggle in Settings > Display & Brightness (or Accessibility) to enable/disable the Liquid Glass UI effects so that I am able to get frosted glass thingy effect that was in iOS 18 back.

Hi, I submitted a Family Controls (Distribution) entitlement request on March 9, 2026 for my iOS app, but I still have not received any approval, rejection, or other status update. At this point, I’m mainly trying to understand: whether this waiting time is currently normal, whether there is any way to check if the request is actually under review, and whether Apple provides any follow-up if more information is needed. This is blocking my progress, because the app depends on the Screen Time / Family Controls APIs. Has anyone recently experienced similar delays, and is there any recommended next step besides waiting? Thanks. Imi
