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

I have an app for iOS already on the AppStore and I'm trying to add a macOS version of it. The AppID prefix for this app is different than my Team ID. This mismatch was always fine for submitting my iOS app. However for some reason, the macOS version gets rejected when I upload it. It tells me the AppID prefix must match my Team ID. I do not control my TeamID and I do not control my AppID prefix, they are both given to me by Apple. Yet the error message tells me they must match. How do I get past this? Here is the error message: Validation failed Invalid code signing entitlements. Your application bundle's signature contains code signing entitlements that aren't supported on macOS. Specifically, the APPID_PREFIX.MY_BUNDLE_ID value for the com.apple.application-identifier key in MY_PACKAGE isn't supported. This value should be a string that starts with your Team ID, followed by a dot ('), followed by the bundle ID. (ID: 930b77ae-099f-4798-a14a-2803f2a9be9e) Thanks in advance for any pointer.

Hello, I am currently implementing External Purchase Link and External Purchase Custom Link and am encountering an issue where both ExternalPurchaseLink.canOpen and ExternalPurchaseCustomLink.isEligible always return false under all test conditions. I would like to confirm whether my setup is missing any required steps or whether this behavior is expected. Below are the details of my current environment and configuration: 🔧 1. Development Environment Xcode: 16.3, 16.4, 26.0 beta 4 Devices: iPhone running iOS 26.2 beta iPhone running iOS 16.7.12 macOS 15.5 (real device testing) Simulator iOS 18.0 Build Type: Local development build using a Developer Provisioning Profile Sandbox account signed in during testing 🔑 2. Entitlements (Developer site & Xcode) In Certificates → Identifiers → App ID, both capabilities are enabled: StoreKit External Purchase StoreKit External Purchase Link The .entitlements file in Xcode includes: com.apple.developer.storekit.external-purchase = YES com.

On my iPhone 16 Pro and iPhone 16 Pro Max devices, running iOS 26.0, 26.0.1, and 26.1, Wi-Fi raw socket communication works flawlessly. Even after keeping the connection active for over 40 minutes, there are no disconnections during data transmission. However, on the iPhone 17 and iPhone 17 Pro, the raw socket connection drops within 20 seconds. Once it disconnects, the socket cannot reconnect unless the Wi-Fi module itself is reset. I believe this issue is caused by a bug in the iPhone 17 series’ communication module. I have looked into many cases, and it appears to be related to a bug in the N1 chipset. Are there any possible solutions or workarounds for this issue?

On XCode 26.x, calling XCFail with continueAfterFailure set to false causes xcodebuild command to hang indefinitely if the XCUIApplication object is stored outside the test method. Create a new template iOS App project with UI tests Add XCFail(...) to a UI test test-case Set the XCUIApplication in self.app (avoiding this fixes the hang) Run tests with xcodebuild test The terminal hangs forever Reproduction example import XCTest final class TestAppUITests: XCTestCase { var app: XCUIApplication? = nil override func setUpWithError() throws { continueAfterFailure = false } override func tearDownWithError() throws { app?.terminate() } @MainActor func testExample() throws { let app = XCUIApplication() self.app = app // <- HERE this causes the problem app.launch() XCTFail() } } Reproduction environment macOS Sequoia 15.7.3 Tested XCode 26.3 and XCode 26.2 have the hang Tested XCode 16.4 does work as expected XCode 16.4 The issue does not happen on XCode 16.4, and is likely introduced in XCode 26.

I am developing an iOS/iPadOS application and have encountered some behavior regarding Files App and security-scoped bookmarks that I would like to clarify. Additionally, I would like to report some behavior which might include a potential issue. Question1: Accessing deleted files via bookmark (Specification clarification) Our app saves file URLs as bookmarks, which file that user has selected on Files App or app-created so to open a file which user has modified previously in the next launch. When a user deletes a file in Files App (moves a file to Recently Deleted), the app can still resolve the bookmark and access the file for read/write operations. Is this behavior intended? In other words, is it correct that a bookmark can access a file that has been deleted in Files App but not permanently removed? Question2: Overwriting a file in Recently Deleted (Potential bug) We noticed that overwriting a file in Recently Deleted behaves differently depending on the method used. Current implementation 1.Crea

Hi everyone, Our team is encountering a reproducible crash when using VTLowLatencyFrameInterpolation on iOS 26.3 while processing a live LL-HLS input stream. 🤖 Environment Device: iPhone 16 OS: iOS 26.3 Xcode: Xcode 26.3 Framework: VideoToolbox 💥 Crash Details The application crashes with the following fatal error: Fatal error: Swift/ContiguousArrayBuffer.swift:184: Array index out of range The stack trace highlights the following: VTLowLatencyFrameInterpolationImplementation processWithParameters:frameOutputHandler: Called from VTFrameProcessor.process(parameters:) Here is the simplified implementation block where the crash occurs.

I opened a new project, iOS app, in XCode and then tabbed into the system_search snippet and built the project and got a build error. I can't imagine this was intended, at least not for new developers to the ecosystem like me. I solved it by tweaking a configuration I don't really understand advised here: https://github.com/apple/swift-openapi-generator/issues/796, hopefully that's a valid workaround

Hi One of the new Family Control API's requires the new Family Controls App & Website Usage capability but it appears to be missing in the latest Xcode beta (26.4 B2). MacOS and iOS all running 26.4 Beta 3. Does anyone know if we have to wait for Xcode 26.4 Beta 3 and it's associated SDK's for this one to become available?

I have Xcode 26.1.1 (installed on a Mac Mini with Sequoia 15.7.2), which was installed from the Universal .xip file available from the Apple Developer site. This file is 2.7Gb. When Xcode is run, there is a menu item at Settings -> Components, and the top section Platform Support includes an option to Get the iOS SDK, which is an additional 10.3Gb download.[1][2] I would like to either use command-line tools to obtain this iOS SDK component, or find where the downloaded package or its contents are installed on this Mac. This Apple Documentation some examples of using command-line tools to download components for Xcode. However, there is no specific documentation on how to separately download the iOS SDK. It seems that if possible, it could be done with xcodebuild -downloadComponent, however I have tried a number of likely component names (ios, ios_sdk, ios26.1, ios_sdk26.1, iphoneos, iphoneos_sdk, iphoneos_sdk26.1), and none are valid. Does anyone know either where the S

Hello App Review Team and iOS Developer Community, We submitted our iOS application on February 25, and within a few hours its status changed to “In Review.” Shortly after that, we received a call from the App Review team requesting some clarification. We provided the requested information during the call, and the same request was later posted in App Store Connect as an unresolved issue. We responded to the request within an hour, providing all the necessary details. However, since then we have not received any further updates regarding the review status. Because this application is related to upcoming sports events, the timing is quite critical. Our client, who owns the sports rights, had planned a launch event on March 6, but unfortunately it had to be postponed because the iOS app was not yet available on the App Store. The sports events are scheduled to begin next week, and our client is planning a marketing campaign ahead of the events, which depends on the app being available.
