Hello, I am currently working on personal project based on Matter. I need to create a Basic Video Player as specified in Matter's standard embedding the Media Playback Cluster. I went through the reading of how Apple now supports Matter as a standard : linkText My understanding of the following schematic, is alongside : HomeKit Accessory Protocol (HAP) Framework API Related HAP accessories underneath the homeKit framework. Developpers also find under the Homekit framework : CHIP (Connected Home IP) Framework API Related Matter accessories this time Both types of accessories/devices can be commissioned in the HomeKit ecosystem seemlessly. Each framework has it's documentation : HAP : https://developer.apple.com/documentation/homekit/hmhomemanager CHIP : https://developer.apple.com/documentation/matter I want through the process of installing XCode and the HomeKit Accessory Simulator. In the list of HomeKit Accessories I did not see any Media related devices : The list of currently supported devices is limited as I read here and will be enriched with time : https://support.apple.com/en-us/102135#:~:text=The%20Home%20app%20currently%20supports,%2C%20temperature%2C%20and%20humidity). In the meantime, as I read the matter documentation, I read several references made to the Media Playback : https://developer.apple.com/documentation/matter/mtrclustermediaplayback https://developer.apple.com/documentation/matter/mtrbaseclustermediaplayback https://developer.apple.com/documentation/matter/clusters#Interacting-with-the-Media-Playback-cluster My questions are : Are Matter Basic Video Players, (Media Playback) supported in HomeKit ? Why aren't they listed in HomeKit Accessory Simulator ? How can I add a Basic Video Player in HomeKit and display it's Media Playback controls once I have added the device to HomeKit ? Thank you for your Answer. Regards David

Since a few days, I'm trying to fetch our private SPM repo hosted on Azure via Xcode but without success. Actually they now accept only ssh key RSA-SHA2-256 or RSA-SHA2-512. So I created a new SSH key, but it seems the problem persists when I try to fetch spm repo or git clone via xcode: "You’re using ssh-rsa that is about to be deprecated and your request has been blocked intentionally. Any SSH session using SSH-RSA is subject to brown out (failure during random time periods). Please use rsa-sha2-256 or rsa-sha2-512 instead. For more details see aka.ms/ado-ssh-rsa-deprecation. remote: ERROR_SSH_UNSUPPORTED_CIPHER (7) (-20)" Even so I'm choosing the good new ssh key, it seems Xcode is sending wrong information about the new generated ssh key. Anyone is experiencing the same here?

Got emailed three .txt crash files. Cannot for the life of me figure out how to get Xcode to do something with them. Tried: renaming .txt to .crash Dropping onto "devices and simulators" window Dropping on to "devices and simulators > select device > View device logs" "Download debug symbols" for the archive in Xcode (says "dowloaded debug symbols" so did it) ... and many other things Xcode 13 simply refuses to respond to the drag-and-drop of the file no matter the file extension and no matter where in Xcode's various windows/tools I drop it. Has anyone done this with a crash .txt file from app review and Xcode 13?

I have a brand new iPhone 15 with iOS 17, paired with a watch on WatchOS10. In devices and simulators, the iPhone 15 and Watch 10 device show up as disconnected (with the globe icon I think is what it is?) and if I click on either of them, that icon changes to a spinner, and the main window says "Xcode will continue when the operation completes", but it NEVER completes. This makes the device not usable for development. In addition, I have updated my iPad to iOS17, and it doesn't even show up at all in the devices and simulator list, even though it is enabled for developer mode. I have toggled developer mode off and on (thus rebooting). I have quit and restarted Xcode. I have even rebooted the Mac. Nothing helps. This is incredibly frustrating.

I have a project that leverages XPC and has interoperability between Swift and Objective-C++. I am presently getting a compile-time error in one of our unit test targets, of "Argument passed to call that takes no arguments" on the following code: let interface = NSXPCInterface(with: XPCServiceDelegate.self) My XPCServiceDelegate protocol is defined as: @objc(XPCServiceDelegate) public protocol XPCServiceDelegate { //... } For the longest time, this code has compiled successfully, and it has not recently changed. There are two confusing things about this error. The first is that I have a different build scheme that will compile correctly other code with the same structure. The other is that I have team members that are able to compile my failing scheme successfully on the same XCode version, OSVersion, and branch of our repository. I've attempted numerous things to try to get this code to compile, but I've run out of ideas. Here's what I've tried: Clean build both on XCode 16.4 and XCode 26 Beta Delete DerivedData and rebuild on XCode 16.4 and XCode 26 Beta Delete and re-clone our git repository Uninstall and reinstall XCode Attempt to locate cached data for XCode and clear it out. (I'm not sure if I got everything that exists on the system for this.) Ensure all OS and XCode updates have been applied. The interface specification for NSXPCInterface clearly has an initializer with one arguement for the delegate protocol, so I don't know why the compiler would fail for this. Is there some kind of forward declaration or shadowing of NSXPCInterface? Do you have any ideas on what I could try next?

Hey all, I recently updated to Xcode 26.2 and I'm having the hardest time trying to download the corresponding iOS simulator. I installed Xcode from developer downloads and the app did not come loaded with an iOS simulator. When trying to download from Components in Settings, I only get the following message: Download failed due to a bad URL. (Catalog download for com.apple.MobileAsset.iOSSimulatorRuntime) Domain: com.apple.MobileAssetError.Download Code: 49 User Info: { checkConfiguration = 1; } I also tried downloading via Terminal but also get a download failed message. I am on the latest macOS and have over 600 GB of disk space available. In previous versions, I was able to download the iOS simulator directly from Developer Downloads, but anything after 26 is not there. Any suggestions?

Ever since Xcode 15 and iOS 17 came out development has quite often been a nightmare of waiting and waiting -Xcode displaying endless circles saying preparing the device, connecting to the device, installing the device. But recently to add to this, installation and launching is just taking really forever. I'm currently running Xcode 15.1 and various versions of iOS 17 (I have several phones) and installing the app from Xcode takes about 7 - 10 minutes (compared to the same app installing in seconds with Xcode 14 for example). Then once its finally installed, it then takes further minutes to launch, Xcode often actually displays a dialog saying its taking longer than expected to launch the app, adding the footnote "LLDB is likely reading from device memory to resolve symbols." What could be reasons, and solutions, for the excruciatingly slow installation time, and launch time? I really need to find a solution to this please - making a code change tweak, running, making another, running, making another, running, just isn't possible given the length of time it takes to install and launch each time. The iPhone is connected via physical cable to the Mac, and the Mac and iPhone are both on the same Wifi network. Xcode 15.1 M1 Macbook Pro Sonomo 14.0 iOS 17.2

Xcode 26.2 RC has been out for over 24 hours and it's still not possible to submit apps.

It was fantastic news to hear, last year, that Xcode was getting a Vim mode. Apple's implementation of it was a great first step, but it was missing a bunch of key features. Most importantly the dot command (and by, extension, macros) and creating marks in files, which are functions that I use/rely on on a daily basis. I thought I would finally be able to stop having to self-sign Xcode (which causes problems) in order to use XVim2 plugin, but no such luck. Will these features get added in for Xcode 14 (they don't seem to be in the beta) or are they far out on the roadmap?

I added a new liquid glass icon built with Icon Composer to my app. It works and looks great on iOS 26 but Xcode complains that required icon files for older versions are missing. I still have the old AppIcon in my Asset Catalog but it seems like it's not being used. How do I configure Xcode to use the old icons for iOS 18 and the new icon for iOS 26?

On iOS 18.0+ simulators, tap any share link button from any app, select "Save to Files", the "Save" button is disabled. In all previous simulator versions this works. This behavior even happens with default Apple apps like Photos. Simulator: Version 16.0 (1037) XCode: Version 16.1 beta (16B5001e) macOS: 14.6.1 (23G93)

When I try to build my iOS app using Xcode Cloud, it encounters an error when trying to resolve packages: an out-of-date resolved file was detected at [path to package.resolved], which is not allowed when automatic dependency resolution is disabled; please make sure to update the file to reflect the changes in dependencies Looking at my package.resolved file, it all seems to be in order. What can I do to fix it?

Hello, I'm unable to run any test cases in Xcode 16 with the iOS 18 simulator. Steps to Reproduce: Create a new iOS project in Xcode 16 using the default iOS app template with the testing option checked. Run any test or UI test case by clicking the "Play" icon in the Test navigator. Xcode gets stuck at the "Testing" state indefinitely. Environment: macOS 15 beta 8 Xcode 16 beta 6 iOS 18 beta 7 simulator

I'm trying to write performance tests with Xcode 15, but it's not working: even though setting a baseline seems to work (baseline data files are created), Xcode seems to ignore that baseline altogether whenever the test is run. As a result, performance tests never fail, no matter how bad performance gets. The source editor persistently displays a “No baseline average for Time” message. Has anyone else encountered this? Figured out how to sidestep the issue? Of note, the issue is easily reproduced: create a new (macOS in my case) app project with tests, add a dummy performance test; run the test once and save its baseline, and despite this subsequent tests will always succeed, even if you significantly slow the dummy test down. (I've filed this as FB13330139)

Hey, I've updated to both Xcode 26 Beta 4 and MacOS 26 Beta 4. Both run super stable so far. However, every time I use Xcode Previews for a few minutes, the entire system freezes for a few seconds and then crashes and reboots. I'm trying to generate a system diagnosis (which it offers me after the reboot), but it seems to be stuck generating. It's hard to say what exactly causes the crash, unfortunately. But it happened multiple times after starting to use Xcode Previews. Anyone else has that problem? I've also filed a feedback for this: FB19013059 Cheers Dennis

with iOS 18.4. I and my colleagues are unable to launch the app. and with the xcode error error.txt

after update to xocde14, build my old project , and get error build: Command SwiftCompile failed with a nonzero exit code.

‌Using Xcode 26, the built package encounters device compatibility issues — while it installs successfully on supported iPhone devices, but it crashes immediately upon launch and cannot run normally.‌‌In previous versions of Xcode, the same "minimum deployment" setting in the project did not cause such compatibility issues.‌ The app built with Xcode 26 shows the following behavior when installed and tested on various devices:‌ iPhone6p iOS12.5.8 fails to run 2.iPhone6 iOS11 fails to run 3.Iphone6 iOS12.5.7 fails to run 4.iPhone7 iOS12.1.3 ok 5.iPhoneX iOS 12.2 ok 6.iphone6s plus iOS10.3.1 ok 7.iphoneXS. iOS 12.1.4 ok 8.iPhone11 iOS 13.6.1 ok 9.iPhone7. iOS 13.7 ok We have tested and found that an iPhone 6s Plus running iOS 10.3.1 can normally run the app. We would like to know whether apps built with Xcode 26 are inherently incompatible with iPhone 6 and older devices. Has Xcode 26’s underlying build environment removed full support for the A8 chip, resulting in binary files containing instructions or memory models that older devices cannot parse? ‌Looking forward to your reply‌.

We've 10 CoreML models in our app, each encrypted with a separate key generated in XCode. After opening and closing the app 6-7 times, the app crashes at model initialization with error: 2021-04-21 13:52:47.711729+0300 MyApp[95443:7341643] Fatal error: 'try!' expression unexpectedly raised an error: Error Domain=com.apple.CoreML Code=9 "Failed to generate key request for 08494FB2-B070-440F-A8A5-CBD0823A258E with error: -42905" UserInfo={NSLocalizedDescription=Failed to generate key request for 08494FB2-B070-440F-A8A5-CBD0823A258E with error: -42905}: file MyApp/Model.swift, line 43 Looks like iPhone is blocking the app for suspicious behavior and the app fails to decrypt the model. We noticed that after ~10 hours the app is unlocked, it successfully decrypts and initializes the model. Opening and closing the app many times in a short period of time is indeed unnatural, but the most important question is how to avoid blocking? Would Apple block the app if a user opens and closes it 10 times during a day? How does the number of models in the app affect probability that the app will be blocked? Thanks!

Hi, we've getting error when we are building our app with Xcode 15 beta versions and Xcode 15.0 public release. ld: B/BL out of range 156662596 (max +/-128MB) to '' To fix this just add -ld64 to Other Linker Flags in Target.
