On Demand Resources does not show an error
I am integrating On Demand Resources into my Unity game. The resources install without any problems if the internet connection is stable: all resources are installed. While testing various scenarios without an internet connection, I encountered the following problem: if I turn off the internet during installation, I don't get any error messages, but if I turn the internet back on, the download no longer continues (and I still don't get an error). If I reopen the application with a stable internet connection, the download will always be at 0%. Please tell me what I am doing wrong. #import "Foundation/Foundation.h" #if ENABLE_IOS_ON_DEMAND_RESOURCES #import "Foundation/NSBundle.h" #endif #include <string.h> struct CustomOnDemandResourcesRequestData; typedef void (*CustomOnDemandResourcesRequestCompleteHandler)(struct CustomOnDemandResourcesRequestData* handler, const char* error); #if ENABLE_IOS_ON_DEMAND_RESOURCES struct CustomOnDemandResourcesRequestData { NSBundleResourceRequest* request; }; extern "C" CustomOnDemandResourcesRequestData* CustomOnDemandResourcesCreateRequest(const char* const* tags, int tagCount, CustomOnDemandResourcesRequestCompleteHandler handler) { NSMutableArray* tagArray = [NSMutableArray array]; for (int i = 0; i < tagCount; i++) { const char* tag = tags[i]; if (tag != NULL) { [tagArray addObject:[NSString stringWithUTF8String:tag]]; } } NSSet* tagSet = [NSSet setWithArray:tagArray]; CustomOnDemandResourcesRequestData* data = new CustomOnDemandResourcesRequestData(); data->request = [[NSBundleResourceRequest alloc] initWithTags:tagSet]; [data->request beginAccessingResourcesWithCompletionHandler:^(NSError* error) { dispatch_async(dispatch_get_main_queue(), ^{ const char* errorMessage = error ?

Attach a debugger to app launched via `devicectrl`
With the latest (26) version of Apple's developer tools, is there a way to manually attach a debugger (other than lldb) to an iOS app launched with "devicectl device process launch --start-stopped"? In the past, this was possible via the ios-deploy third-party tool (now defunct), which provided a debugserver port. This information is notably missing when using devicectrl – although the process ID of the launch process is provided, and the tool is clearly aimed at letting you launch and attach to processes from the command line. lldb can, of course, attach via its built-in support for this using the device set of commands. But I'm explicitly looking for a way to attach my own debugger via the GDB-compatible debug proxy.

On demand module download
I am working on an iOS app and I want to achieve on demand module download inside the app when the user clicks on the module icon which he wants to use. The idea is that we have a super app consisting of multiple modules say four independent apps/features and I want to separate each one so that when the user selects a specific app/feature, it’s downloaded on demand and then opened directly within the same super app resulting in a lower app size initially I want to upload all the code of all modules to app store connect but when the user downloads the app, then only one module's code should be available to the user, the rest of the module's code should be downloaded when the user wants to use that module. I know apple restricts downloading new code but in my case I want to upload all the code to app store for review but just give option to the user to get rest of the code when needed. Any guidance, architectural advice, or example implementations would be highly appreciated.

How are Assets removed?
Hello, I'm trying to figure out the behavior of AssetPackManager.shared.remove(assetPackWithID: ). I'm working with MapKit tiles and currently working on trying projecting them correctly which involves serving the AssetPack locally, downloading, checking alignment, and then deleting and changing. My question is that remove(assetPackWithID: ) completes successfully and the asset pack is removed. This is confirmed by trying to remove the AssetPack again which throws an error. However, the asset is still appearing on MapKit after the removal. This is a bit odd as this persists not only with force killing, but also restarting the device. Please advise on how to properly remove an AssetPack. Thank you iPhone 15 Pro Max (iOS 26.0.1) iPhone 17 Pro Max (iOS 26.0.1)

Fake JournalingSuggestions for testing?
I want to test different types of journaling suggestions, like for example photo/video containing ones but as a developer I have no control over what's shown in the Journaling Suggestions sheet. And this makes it really difficult to develop or test any suggestion type other than "reflection". Please let us have a fake suggestions sheet that includes all kinds of suggestion types so we can test. We could toggle it under Developer settings I think.

Background Assets Directory Collision
Hello, I'm trying to use multiple Background Assets Packs to host map tiles. This is problematic for a few reasons. MKTileOverlay requires a method that returns a URL. AssetPackManager.shared.url() throws, but it's unrelated to the url. It will return a URL even if it points to nothing. There's no name-spacing. Everything appears to be flattened. (See Error below) Simultaneously, this also is not the case as the documentation states: if there’s a path collision across multiple asset packs, then it’s undefined from which asset pack an individual file will be resolved. AssetPackManager.shared.url() doesn't have an optional parameter to explicitly declare the asset pack you want to access, like AssetPackManager.shared.contents(at: FilePath) does For example, I have multiple different tiles I'm trying to overlay for z: 10, x: 239, and y: 414. Foo/10/239/414.png Bar/10/239/414.png And even when explicitly stating the fold directory, it appears that the assets are flattened down. As I'm receiving this error. The URL for “Foo/10/239/414.png” couldn’t be retrieved: “414.png” couldn’t be copied to “239” because an item with the same name already exists.

Inconsistent results involving code signatures and bundles
I admit I am doing something unusual, and I would not be surprised if it didn't work. I am surprised, however, because after performing the equivalent operations on four bundles, all of the bundles work fine on macOS 15.6.1, but only two of them work on macOS 26.1 (beta 2). I don't know what causes the different outcomes. What I am trying to do is get Java to pass the macOS 26 AppKit UI SDK linkage checking without having to rebuild the JDK using Xcode 26. Rebuilding works for the latest SDK, but it is very inconvenient and may not work for older JDKs. It usually takes a while before the JDK build team successfully transitions to a new Xcode release. My approach is to use vtool to update the sdk version in the LC_BUILD_VERSION load command of $JAVA_HOME/bin/java, which is the launching executable for the JDK. I performed this operation on four JDKs: 25, 21, 17, and 11. (I ran vtool on macOS 15.) It was completely successful on JDK 25 and 21. The JDK launches correctly on macOS 15 and macOS 26. On macOS 26, AppKit uses the new UI, which is the desired outcome. The JDK runs despite that fact that I signed the modified $JAVA_HOME/bin/java with my developer ID, which is inconsistent with the JDK bundle signature. (Redoing the bundle signing is part of the JDK build process; if that were necessary, I would stick with rebuilding the JDK.) The operation was not successful on JDK 17 and 11. I noticed two problems, which are not obviously related. When vtool created the new version of the java program, it lost the tool definition. $ vtool -show-build-version java java: Load command 10 cmd LC_BUILD_VERSION cmdsize 32 platform MACOS minos 11.0 sdk 11.1 ntools 1 tool LD version 609.8 $ vtool -set-build-version 1 10.0 26.0 -output a.out java /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/vtool warning: code signature will be invalid for a.out $ vtool -show-build-version a.out a.out: Load command 22 cmd LC_BUILD_VERSION cmdsize 24 platform MACOS minos 10.0 sdk 26.0 ntools 0 Adding back the tool definition didn't seem to matter. When I try to run the revised executable (in the context of the JDK bundle), it works on macOS 15, but on macOS 26, it is rejected as damaged. If I run the revised executable outside the JDK bundle, it runs (but fails because it can't find the rest of the JDK, which is expected). In all cases, GateKeeper rejects the revised executable because it has not been notarized, but that doesn't seem to stop the program from executing.

Testing Family Controls & Multicast Networking APIs - Educational Use Without Paid Developer Account?
Hi Apple Engineers and fellow developers, I'm a student developer working on an educational focus management app that helps users hide distracting apps during study sessions. The app consists of: macOS app: Simple "Hide apps" button that triggers app hidding sessions iOS app: Uses Screen Time API to temporarily hide selected apps from home screen Communication: Bonjour networking between Mac and iPhone for session coordination The Challenge My app requires two entitlements that aren't available with Personal Developer Teams: com.apple.developer.family-controls (for Screen Time API) com.apple.developer.networking.multicast (for Bonjour device discovery) Current Error Messages text Cannot create a iOS App Development provisioning profile for "focuser.focuser-app". Personal development teams, including "My Name", do not support the Family Controls (Development) capability. Provisioning profile doesn't include the com.apple.developer.family-controls and com.apple.developer.networking.multicast entitlements. My Question for Apple Engineers Is there any legitimate way to test these privacy-sensitive APIs on my own devices for educational/learning purposes without purchasing the $99/year Apple Developer Program membership? I understand the security reasons behind these restrictions, but as a student just learning iOS development, it creates a significant barrier to experimenting with these technologies.

Xcode Code coverage shows zero; even after 245 successful tests
I have a project inside the project structure. I have around 300 unit tests in the project. I see that for some of the subprojects, the coverage numbers show up correctly, but for other subprojects and the main project, the coverage number shows zero, even though the tests are running successfully. The log I get is: Aggregation tool emitted warnings: warning: /Users/ABC/Library/Developer/Xcode/DerivedData/projectABC-hfzmkbdgpiswoxfvvnvhrafaiqyb/Build/ProfileData/A8EEC1FB-1699-4C29-A88C-D3DDA226DBC0/0A416494-A393-4319-AA47-502D72084C9C-43351.profraw: raw profile version mismatch: Profile uses raw profile format version = 8; expected version = 10 PLEASE update this tool to the version in the raw profile, or regenerate the raw profile with the expected version. I only have one Xcode (26.0.1) on my machine. I tried cleaning the derived data, the cleaning project, and rerunning the tests, but it hasn't helped. Please help me get the coverage number back. Thank you.

Embed/Do Not Embed & Mach-O type
My Xcode project has the following configuration: 1 iOS app target 1 Xcode framework target (mach-o-type "Dynamic Library") 5 static libraries Dependencies: All the static libraries are target dependencies of the framework. The framework is the only target dependency of the iOS app. For the iOS app target, within the General tab > Frameworks, Libraries & Embedded content, I've set the framework as "Do not embed" So now I have a dynamic framework which won't be copied to the .app bundle in the build output. As per my understanding, this should result in a runtime error, dyld should not be able to find the framework files as they were not embedded in the final .app bundle. But regardless, my app runs without any errors, using all the methods exposed by the framework. What is the correct understanding here? What exactly does Embed/Do not embed mean (apart from excluding the files from .app bundle) When both settings are specified, is there any priority or precedence of one setting over the other?

What is the unit used for the availableKilobytes property of the target object?
In the online documentation for InstallerJS, it is stated that the unit for the availableKilobytes property of the target field is kilobytes. Isn't it actually bytes because of a bug in the very first release of macOS that supported InstallerJS? [Q] Has there been a fix in the recent years regarding this property that would explain why the documentation says it's kilobytes? Even though at the time of this writing, the unit is still bytes when you call my.target.availableKilobytes I'm using this call to dump the value of this property in install.log: system.log(my.target.availableKilobytes + ''); Ref. https://developer.apple.com/documentation/installer_js/target/1811975-availablekilobytes (FB20448952)

LibGDX/MobiVM App refuses to launch on iOS 26.0.1
Hello, currently I am having trouble releasing an app because it crashes/does not launch on iOS 26.0.1. We have uploaded apps in the past so I tried building one of them with our current toolchain. I use Xcode 16.4, Kotlin version 2.0.0, LibGDX 1.13.1 and robovm/MobiVM 2.3.23. I uploaded the build to TestFlight and tested with physical devices running iOS 18.5 and 26.0.1. It runs fine on 18.5 but refuses to launch on the 26.0.1 device. I cannot retrieve a crash log or .ips file because none is written. When I write a Console log while the app crashes/does not launch I get no hints as to why it does so. Do you maybe have additional ideas as to why it keeps not launching on iOS 26.0.1?

How to implement background notifications with action buttons (Accept/Decline) in iOS Flutter app?
I am developing a Flutter app for food delivery (a multivendor e-commerce restaurant app). In the vendor app (Android), I successfully implemented a background notification that stays active until the vendor responds with either Accept or Decline. This works fine on Android, but I cannot get the same functionality working on iOS. My requirements: Vendor should receive a background notification. The notification should include action buttons (Accept / Decline). It should remain active until the vendor takes action. My questions: Is this possible to implement in iOS with Flutter? If yes, what is the recommended way (e.g., firebase_messaging, flutter_local_notifications, flutter_foreground_task, or native iOS integration)? Are there any iOS restrictions I should consider compared to Android background services? I built this for Android using firebase_messaging + flutter_foreground_task + flutter_local_notifications. On iOS, I tried setting up firebase_messaging and flutter_local_notifications, but I’m unable to keep the notification persistent with Accept/Decline action buttons. I expected similar behavior to Android, but it seems iOS has more restrictions around background services and notification handling. Dependencies I am using (relevant ones): firebase_core: ^3.8.0 firebase_messaging: ^15.1.5 flutter_local_notifications: ^17.2.2 flutter_foreground_task: ^8.17.0 get: ^4.7.2 shared_preferences: ^2.3.2

Automatic Provisioning fails in VisualStudio 2022
Hi there, I am trying to create my first iOS app using Visual Studio (Win 11) and .NET MAUI. I created a developer account and if I want to start the debugger with my local device, VS forces me to Configure Automatic Provisioning. I can select my configured account but the operation fails (see screenshot). I have no idea what is going wrong and I cannot find any setting in the developer account to fix this problem. Can anyone help me out, what is wrong and how to fix, thx!
