I can see that a MacOS VM guest running on top of an Apple Silicon MacOS host has GPU acceleration - indicating GPU sharing capabilities for the hardware. Is there also a way to have GPU acceleration in Linux guests (with Vulkan/Mesa drivers)?

Hello Everyone, (and I hope folks at Apple are listening) So around a year ago, I decided to take on the challenge of creating my own Iphone App from scratch. I am an engineer by trade, and thought it would be a fun interesting experience, and maybe make some money on the side. So I bought a macbook, and focused on learning Swift for the next few months. Lots of really great developer folks helped me along the way. And I could not have been successful without so much help. It is very much appreciated. So I finished the app, created my own company. And deployed it to the Istore. Unfortunately, just no interest, I think I sold like 4 copies. No problem, still got to learn a lot along the way. So when it came time to renew my developer licence, I let it expire. Just did not make any sense to drop another $100 into it, since only 4 copies had sold in a year. And then..... this happened!!!! I attempted to use the App that was installed on my own Iphone.... and got the message "My Apps Name" is no longer Available. and it stops... The code is on my phone. I am fully aware that I can no longer use xcode to put anything else on my iphone without a developer licence. But for Apple to reach into my own Iphone, and deny my access to something that I already created, (and in theory already paid for) is just infuriating!!! I checked, and even though it no longer exists in the IStore, purchased copies still seem to function. (one person that bought a copy was a friend of mine). So do I really need to drop another $100, puchase an actual copy of MY OWN APP from the app store, just to have it on my own phone again???!!! So much money and time went into this, that I am considering just smashing every apple product I own, and go with Android instead. I am a single person developer. Almost no one does this sort of thing anymore. Apple used to be the place where innovators could come to try to make something cool and fun to use. I guess not any more. Dan

Hi everyone, I'm developing a visionOS application using Unity with an enterprise developer account. I applied for the Main Camera Access entitlement, but at the time of submission, the email address associated with my Apple ID was deactivated, so I couldn’t receive any email communication from Apple. Later, I updated the email address for my Apple ID. Now, in the Apple Developer portal under Identifiers, I can see that my app has been granted Main Camera Access, and I can also add the corresponding capability in Xcode. However, according to Apple’s documentation(https://developer.apple.com/documentation/visionos/building-spatial-experiences-for-business-apps-with-enterprise-apis): “To use entitlements, you need to include both the entitlement file and a corresponding license file in your app. After Apple approves your app for one or more entitlements, you receive a license file, along with additional instructions.” I never received this license file, possibly due to the deactivated email. I don't know where to find it or how to retrieve it now. What exactly is this license file? If it was originally sent to an unreachable email, how can I request it again or get it resent? Where in the Apple Developer portal (or elsewhere) can I access or download this file? Any help or guidance would be greatly appreciated! Thanks in advance.

As of now, there is no Kernel Debug Kit (KDK) available for macOS 26.0 Developer Betas after the first build. Kernel Debug Kits are crucial for understanding panics and other bugs within custom Kernel Extensions. Without the KDK for the corresponding macOS version, tools like kmutil fail to recognize a KDK and certain functions are disabled. Additionally, as far as I am aware, a KDK for one build of macOS isn't able to be used on a differing build. Especially since this is a developer beta, where developers are updating their software to function with the latest versions of macOS, I'd expect a KDK to be available for more than one build.

Q. Is there a plan to finally document the PackageInfo file format used in .pkg flat package? The man page for pkgbuild is not really useful to understand the different options. It does not seem to make sense to have an official documentation for the Distribution Definition file but not for the PackageInfo file.

I get a crash in Apple Watch simulator (Series 9 45mm 18.0) as soon as the app launch if I type anything on external keyboard (just hitting command key for instance to capture a screenshot). Same crash on series 7 (45mm, OS 18.1) But app works normally when I use mouse to interact with the app on simulator. App does not crash on real device (Watch 4 OS 10.4.1). Nor does it crash on Series 6 simulator (44 mm OS 17.4). Here are the log I could collect (apparently, they contain sensitive language !!! so I attach as a file.: Attached logs

Hello, I'm doing an update to my app already IN the app store. The app is built using .Net Maui targeting iOS, Windows and Android. All works fine in debug and in release on Android and Windows. However, the app launches on my iOS devices and crashes immediately. I really have no idea what the crash report on the device is telling me. Attached is the .ips file if anyone can at least point me in the right direction... Thanks MyApp-2025-03-01-202630.ips

Hello, Good morning to you all. Please I need a guide on how to change my app icon on the developer account. Necessary steps would be appreciated Thanks for the anticipated assistance. Best Regards Biggie

Here's a simple C++ program that echoes its arguments... #include <stdio.h> int main(int argc, char* argv[]) { for (int i=0; i<argc; ++i) printf("%d %s\n", i, argv[i]); } This works as expected... > ./test arg1 #arg2 arg3 0 ./test 1 arg1 2 #arg2 3 arg3 Running under lldb gives this... > lldb ./test arg1 #arg2 arg3 (lldb) target create "./test" Current executable set to '/Users/richard/Work/test' (arm64). (lldb) settings set -- target.run-args "arg1" "#arg2" "arg3" (lldb) run Process 6138 launched: '/Users/richard/Work/test' (arm64) 0 /Users/richard/Work/test 1 arg1 Process 6138 exited with status = 0 (0x00000000) I get the same if I quote the arguments, or if I add them to the run line. Stepping into main() we see the argv and args values are as though we only had the first argument. If I quote the second argument and add an initial space " #arg1" then it works. I first saw this on an M1 running Sequoia 13.1. It am now on OS 13.3. lldb --version lldb-1600.0.39.109 Apple Swift version 6.0.3 (swiftlang-6.0.3.1.10 clang-1600.0.30.1)

Hello, Is there a way to retrieve the dark mode and the tinted app icons using personal iOS device, or alternatively through an available API? I wasn't able to find anything online or on the existing form posts. I tried using: xcrun devicectl device info appIcon But this command only returns a light mode icon for an app and I didn't see any options/flags for dark mode or tinted icons Software Version info: XCode - 16 MacOS 15.1 Beta (24B5070a) devicectl - 397.21 xcrun - version 70, platform version 15.0 Let me know if any other info would be helpful. Thanks!

Under macOS 26 and iPadOS, the Help menu in many cases has a menu item for "App Help". This item has the following icon: I need to use this in my own app. I am unable to find this icon in SF Symbols 7 beta. I've scanned all of the icons under "What's New". I've searched for "help", "light", and "bulb" and this icon does not appear. Does anyone know if it's even a new SF Symbol? Or does anyone know of a way to use this icon?

I was developing an app using a certain bundle ID, but then had to delete it (and I also removed the app ID Identifier) My question is, can I make a new app with the exact same bundle ID as I was using on the removed one? Since the old app never went into production I don't see why that would be a problem

I have added 2 command line tools in my swiftUI app for macOS, it was working fine locally, but it gives error when i try to make archive of it. I am not sure about the reason, but it was related to sandboxing the command line tools, after this i have tried multiple solutions but i am unable to resolve this issue, how should i handle the helper command line tools

I've got a bunch of AudioUnit projects approaching release, and am attempting to build an installer for them. All are based on the AudioUnit template in Xcode 14. What actually governs how the system detects an AudioUnit? The instructions I have seen say that the built .appex should be renamed to have the extension .component and installed into /Library/Audio/Plug-Ins/Components/ - great, I am able to build a signed installer that does that (i.e. strip out the built Application project that is part of the AudioUnit template but useless to, say, a Logic Pro user), include the .appex that declares the plugin and embeds a Framework that contains the actual code (so it can be loaded in-process). auval -l does not show it after running the installer, nor does Console show anything logged suggesting that it was found but malformed or something like that. Meanwhile, simply building the project causes auval -l to show an install of it in the build directory, and I have noticed that if I delete that, auval -l would still show the plugin installed, but now in the location I exported an archive of the project (!!). What black magic is this? However, deleting both the recent build and the archive, after running the installer, and there is no indication that AudioComponentRegistry even sees the copy of it in one of the two locations actually documented to be valid install locations for an AudioUnit. I have, however, installed one third-party free AUv3 which installed into /Library/Audio/Plug-Ins/Components/ Am I misunderstanding something about how this works? Is there some string other than AudioComponentRegistry I should filter on in Console that might provide a clue why my AudioUnit installed there is not picked up? Must I ship the semi-pointless Application that is part of the Xcode template project, and whatever magical mechanism detects it when I build will work its magic on end-users' machines? Or could the problem be that the Framework with the actual code under Contents/Frameworks inside the audio unit, rather than installed independently into /Library/Frameworks?

In the archived documentation for Distribution Definition files (https://developer.apple.com/library/archive/documentation/DeveloperTools/Reference/DistributionDefinitionRef/Chapters/Distribution_XML_Ref.html), the allowed-os-versions and os-version element are partially documented. I have a few questions about these elements: allowed-os-versions The documentation states: Availability: Available in OS X v10.6.6 and later. Has this element always worked correctly in the past? I'm asking because it does not seem to work correctly on OS X v10.14 for the min attribute of a sub os-version element. os-version The documentation states: This element is designed for you to use a specific OS version number for the min attribute, and a major OS version number for the before attribute. The expectation is that you will know an exact minimum version but not an exact major version. This keeps you from having to guess the last minor revision before the next major revision, as you would have to do if the before attribute were inclusive. This is quite confusing because the documentation never explicitly says what a specific or major OS version number is. Is specific major.minor.patch or major.minor? What is major? major or major.minor? As the documentation was created at a time where the OS version scheme was: 10.minor.patch (and minor was actually the major) and we are now in an era where the OS version is major.minor.path, this is even more confusing. I would also be curious to know what the major version is officially supposed to be for macOS Tahoe in this case. 16 or 26? Generally speaking, this documentation is missing examples for a lot of the elements. Also why is there a tag for InstallerJS and not one for Installation in the Developer Forums?

So, as we found out from WWDC, the migration to Apple Silicon is inevitable. Does anyone have a good recommendation for a replacement for Macintosh Common Lisp on Apple Silicon? I was using it back in the MPW days and struggling to keep the Lisp code working, but Apple Silicon has thrown a money wrench at it! Thanks in advance for any advice on any available Apple Silicon Lisp development tools!

My experience with Swift 6 strict concurrency so far doesn't match my understanding of implicit MainActor isolation semantics. This is a cross-post from StackOverflow. I will link answers between both forums. TL;DR Build succeeds when testing a struct declared in the test module, but fails when the struct is moved to the main module: Main actor-isolated property … cannot be accessed from outside the actor. Steps to reproduce Open up Xcode 26 beta 2 on macOS 26 (probably also ok on current stables). Create a new Swift app with Swift testing, no storage. Call it WhatTheSwift. Set the Swift Language Version on all three targets to Swift 6. Update the default test file to be this: import Testing @testable import WhatTheSwift struct WhatTheSwiftTests { @Test func example() async throws { let thing = Thing(foo: "bar") #expect(thing.foo == "bar") } } struct Thing { let foo: String } That should build fine, and the tests should pass. Now, move the Thing declaration into its own Thing.swift file in the WhatTheSwift module, and try running the test again. You should see this: Observations Marking the test @MainActor allows the test to pass, suggesting the compiler actually wants to isolate Thing.foo to the main actor. My question Why? And why only when Thing is in a different module?

I can see that iOS beta 2 was released yesterday. I'm not running the beta yet on my actual iPhone, but I wanted to see if an issue I reported in beta 1 was fixed. Is there a way to update my iOS 26 simulator for beta 2? Usually, there's a new Xcode download that includes the new simulator, but it looks like the most recent Xcode beta release was June 9.
