We're trying to implement a backup/restore data feature in our business productivity iPad app using UIDocumentPickerViewController and AppleArchive, but discovered odd behavior of [UIDocumentPickerViewController initForOpeningContentTypes: asCopy:YES] when reading large archive files from a USB drive. We've duplicated this behavior with iPadOS 16.6.1 and 17.7 when building our app with Xcode 15.4 targeting minimum deployment of iPadOS 16. We haven't tested this with bleeding edge iPadOS 18. Here's our Objective-C code which presents the picker: NSArray* contentTypeArray = @[UTTypeAppleArchive]; UIDocumentPickerViewController* docPickerVC = [[UIDocumentPickerViewController alloc] initForOpeningContentTypes:contentTypeArray asCopy:YES]; docPickerVC.delegate = self; docPickerVC.allowsMultipleSelection = NO; docPickerVC.shouldShowFileExtensions = YES; docPickerVC.modalPresentationStyle = UIModalPresentationPopover; docPickerVC.popoverPresentationController.sourceView = self.view; [self presentViewControl

Testing Environment: iOS Version: 26.0 Beta 7 Xcode Version: 17.0 Beta 6 Device: iPhone 16 Pro Description: We are implementing the new BGContinuedProcessingTask API and are using the wildcard identifier notation as described in the official documentation. Our Info.plist is correctly configured with a permitted identifier pattern, such as com.our-bundle.export.*. We then register a single launch handler for this exact wildcard pattern. We are performing this registration within a UIViewController, which is a supported pattern as BGContinuedProcessingTask is explicitly exempt from the register before applicationDidFinishLaunching requirement, according to the BGTaskScheduler.h header file. The register method correctly returns true, indicating the registration was successful. However, when we then try to submit a task with a unique identifier that matches this pattern (e.g., com.our-bundle.export.UUID), the BGTaskScheduler.shared.submit() call throws an NSInternalInconsistencyException and terminates

I'm trying to implement Unwanted SMS and Calls reporting in an app I'm doing in my idle time. If I place a UITextField or UITextView inside a ILClassificationUIExtensionViewController, every time I select on such control the extension crashes without any logs. The closet idea I have on why it crashes it has something to do with iOS requesting the dictation feature. I'm using the latest (beta 8 at the time) iOS 16.0 beta on my iPhone 13 pro. Attaching my code here if you want to try for yourself: github

Hey, We're crunching to get our products ready for the announcements next week but are being slowed down by Xcode Cloud. Builds are failing and are extremely slow. We're using the latest Xcode beta and latest macOS release so we can upload our builds continuously to TestFlight. We're seeing builds taking up to almost an hour, even though takes around 10-15 minutes when it doesn't fail. The errors we're seeing seem to be timeout, for example: Showing All Errors Only The step invocation hit a user timeout. The xcodebuild build invocation timed out. No activity has been detected on stdout, stderr or the result bundle in 30 minutes. Here are links to some builds which have been restarted multiple times but keep failing for reasons out of our control. Please advice on how to get unblocked. https://appstoreconnect.apple.com/teams/69a6de80-3540-47e3-e053-5b8c7c11a4d1/apps/1102236212/ci/groups/8da12ae3-b454-4810-abe8-829f1af56a54 https://appstoreconnect.apple.com/teams/69a6de80-3540-47e3-e053-5b8c7c

Hello all! Trying to find list of all XCode project parameters or build settings within description. Is there any documentation? Need something that will help me to understand list of project properties when running command in project folder: $ xcodebuild -showBuildSettings Command line invocation: /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -showBuildSettings User defaults from command line: IDEPackageSupportUseBuiltinSCM = YES Build settings for action build and target test: ACTION = build AD_HOC_CODE_SIGNING_ALLOWED = NO AGGREGATE_TRACKED_DOMAINS = YES ALLOW_BUILD_REQUEST_OVERRIDES = NO ALLOW_TARGET_PLATFORM_SPECIALIZATION = NO ALTERNATE_GROUP = staff ALTERNATE_MODE = u+w,go-w,a+rX ALTERNATE_OWNER = alexandr ALTERNATIVE_DISTRIBUTION_WEB = NO ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES = NO ALWAYS_SEARCH_USER_PATHS = NO ALWAYS_USE_SEPARATE_HEADERMAPS = NO and may other parameters Need to know meaning of this kind of parameters.

According to the ARM documentation for the CPU models available in Apple Silicon, the CoreSight implementation includes an Embedded Trace Macrocell which can perform a complete Instruction Trace (https://developer.arm.com/documentation/102119/0200/What-is-trace-). Although other operating systems such as Linux make this easy, we have not been able to find any tools or even a system-level API for accessing this feature of the ETM. In the Instruments window of Xcode 16+, there is a Processor Trace instrument, but this performs sampling and is totally unrelated to the Instruction Trace we need for debugging and analysis purposes. Because it produces a complete, contiguous sequence of branch instructions, the Instruction Trace is essential for identifying precise execution behaviors that are otherwise invisible to the developer. On other platforms, an alternative is debugger scripting, but we have found far too many bugs and reliability issues with the macOS implementation of lldb. Any suggestions would

I've been playing with the new GameSave API and cannot get it to work. I followed the 3-step instructions from the Developer video. Step 2, Next, login to your Apple developer account and include this entitlement in the provisioning profile for your game. seems to be unnecessary, as Xcode set this for you when you do step 1 First add the iCloud entitlement to your game. Running the app on my device and tapping Load starts the sync, then fails with the error Couldn’t communicate with a helper application. I have no idea how to troubleshoot this. Every other time I've used CloudKit it has Just Worked™. Halp‽ Here is my example app: import Foundation import SwiftUI import GameSave @main struct GameSaveTestApp: App { var body: some Scene { WindowGroup { GameView() } } } struct GameView: View { @State private var loader = GameLoader() var body: some View { List { Button(Load) { loader.load() } Button(Finish sync) { Task { try? await loader.finish() } } } } } @Observable class GameLoader { var directory: G
