Xcode 16 | xcodebuild fails when providing -destination 'platform=iOS Simulator,name=iPhone 16,arch=x86_64'
Hello. In the Xcode 15 we were using this command in the terminal to run our tests on the Rosetta Simulator: xcodebuild -workspace CoreLibraries.xcworkspace -scheme CoreLibraries -destination 'platform=iOS Simulator,name=iPhone 15,arch=x86_64' test` In the Xcode 16 the same command doesn't work anymore. It produces the error: xcodebuild: error: Unable to find a device matching the provided destination specifier: { platform:iOS Simulator, arch:x86_64, OS:latest, name:iPhone 16 } Unsupported device specifier option. The device “iPhone 16” does not support the following options: arch Please supply only supported device specifier options. Running test directly from the Xcode UI using iPhone 16 (Rosetta) still works fine. Does anyone know how to modify the xcodebuild command to make it work again?

Icon Composer: Any way to add icons to the app bundle for older macOS versions?
Several app developers are struggling with the inability to provide a separate app icons that looks nice on older macOS versions while at the same time provide Icon Composer icons that look great on macOS Tahoe 26. An ability to provide separate icons is super important to those who have app icons that follow the curvature of the default icon borders (as the corner rounding radius is different for Sequia and Tahoe). Take a look at this for example: https://github.com/ghostty-org/ghostty/issues/7564#issuecomment-3042061547 Question: Is there a definitive/recommended way to address this issue? How can a developer add a glass icon variant that looks good on Tahoe and provide a bitmap icon for older macOS versions? Some background info: Prior to Xcode 26 beta 4, one could add an App Icon to Assets to be used as app icon for legacy macOS versions (Sequia and older) and use a new Icon Composer icon (placed in the project root) for macOS Tahoe 26. Enabling "Include all app icon assets" under target settings ensured that older macOS versions would use the old app icons while Tahoe the new Icon Composer glass one. Since Xcode beta 4 this technique no longer works. Xcode instead insists on populating Assets.car with Icon Composer generated variants, disregarding the App Icon provided in Assets. Although the App Icon in Assets makes its way to a .incs file in the app bundle's Contents/Resources folder, but that is not used by macOS anymore and is there for some compatibility purposes. The Assets.car file (which matters) only contains the variants generated by Icon Composer and does not contain the png icons provided in the Assets.

Xcode debugger doesn't pause on breakpoints (simulator SDK < iOS 17)
Hello. I'm seeing an inconsistent behavior where breakpoints I set in my (Swift) iOS app behave normally when I'm debugging on a device or on a simulator running iOS 17.x, but when I try using simulators of iOS 16 or 15 the breakpoints get ignored completely. I also observe that the breakpoints remain solid blue and do NOT adopt the dotted blue outline, as experienced by other users. I've seen a few posts on here and on SO about the general issue of ignored breakpoints (with no conclusive answer AFAIK), but I haven't seen any where the behavior varies with the SDK being used. The behavior is repeatable and predictable (within the same app at least). I am not adding the breakpoints after building/running, and I'm sure the logic reaches the lines with the breakpoints (and again, whenever I switch to an iOS 17 simulator, execution does pause as expected with the exact same breakpoints). Things I've tried and looked into: Clean up project build folder Delete and re-install simulators (iOS 16.4 and 15.5) Deleted the entire derived data directory, as well as the CoreSimulator one. Confirm the build configuration is Debug, and the "Debug executable" option is checked. inspect various build flags mentioned in other posts: {Swift compiler - Code generation - Optimization level - Debug: -0none; Debug information format: DWARF (I also tried DWARF with dSYM with no impact)}. Most of my settings are on the plain vanilla/out of the box side, with only a couple of SPM dependencies, and I've been maintaining the same app for about 5 years and don't think I've come across this behavior before. Currently using Xcode 15.1. Deployment target is 14.0. Thank you.

Xcode Cloud: The page you’re looking for can’t be found.
We started seeing an access issue today when attempting to go to the Xcode Cloud tab in App Store Connect. When you navigate to https://appstoreconnect.apple.com/teams/:teamId/apps/:appId/ci we're seeing the following message: The page you’re looking for can’t be found. The page you’re looking for does not exist, or you do not have permission to view it. I am the account holder so it shouldn't be a permissions issue. Is there an ongoing outage or problem in Xcode Cloud? And, if so, where can I monitor this accurately?

Need to know how to stop indentation
Xcode 16 unindents lines if I choose a code-completion and I cannot find a way to stop this - does anybody know how to stop it? Here's a link to a gif demonstrating this problem - it's incredibly frustrating. https://i.imgur.com/jaDpzpb.gif Thanks in advance

Is a spam an appreciated participation in the forums ?
There are at the moment a lot of spams for a bank phone number. https://developer.apple.com/forums/thread/769506 What is really surprising is to read App Store Connect Engineer answer, each time the same: We appreciate your interest in participating in the forums! These forums are for questions about developing software and accessories for Apple platforms. Your question seems related to a consumer feature and is better suited for the Apple Support Communities Is it an automatic answer (I cannot believe anyone who read the post did not notice it was a spam) ? If so, couldn't it simply detect it is a spam (Apple Intelligence could come to help) and delete the message (or the account) ? PS: it would also be a spam in Apple Support Communities PS2: I note the message has been deleted very rapidly.

Xcode 26 Beta 4 Build Failures
We are trying to track down some build failures that started happening only in our Jenkins CI environment. error: Failed to decode version info for '/Applications/Xcode.app/Contents/Developer/usr/bin/actool': The data couldn’t be read because it is missing.

Unable to Verify Code Signature with Error 0xe8008018 Despite Troubleshooting Attempts
Hello everyone, I am encountering a persistent issue with Xcode where I’m unable to install my app on a testing device due to the following error message: Failed to verify code signature of /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.SznYNY/extracted/iForC.app : 0xe8008018 (The identity used to sign the executable is no longer valid.) Here’s what I have tried so far to resolve this issue: 1. Ensured that all my certificates and provisioning profiles are current and valid. 2. Removed all related certificates from my Keychain and reinstalled new ones. 3. Cleaned and rebuilt the project multiple times. 4. Unpaired the device and paired it again. 5. Reinstalled the latest version of Xcode. 6. Performed a complete restore of my Mac. Despite these troubleshooting steps, I am still facing the same issue. I would greatly appreciate any insights or experiences related to this error from anyone who has overcome similar challenges. Thank you in advance for your help!

Xcode 26 Beta 5 XIB Compiler outputs NIBs with dependency on class that isn't available pre-macOS 26
When Xcode 26 Beta 5 compiles my XIBs into NIBs, it spits out a dependency on a class that isn't available pre-macOS 26, named _TtCC6AppKit14NSScrollPocketP33_EC3F85FAB7755D56E669206D2B17725B12BackdropView. All XIBs have a deployment target of macOS 12, so in theory this should be avoided. Even if this is a new (internal) class to macOS 26, the dependency is a problem when the developer is asking to deploy to prior versions. Has anyone else run into this regression? What could possibly be causing the XIB compiler to inject this dependency? The resulting NIBs don't load on anything prior to macOS 26.

Xcode Cloud won't load from Xcode or App Store Connect
I am setting up a new app and am having problems with Xcode Cloud. From Xcode if I click on the "Cloud" button under the Report Navigator I get a spinner for a long time then get the message "Could not load Xcode Cloud data". I also visited the "Xcode Cloud" tab under my app in App Store Connect and I get a spinner and nothing loads. This is a recent account and I'm setting up Xcode Cloud for the first time. Below is what I've tried and I'm out of ideas on how to get this working. In Xcode, I signed out and back in as the Account Holder Closed Xcode and reopened This occurred yesterday and today and have not seen a problem under the Apple System Status page On the latest Xcode 16.2 Checked the Signing & Capabilities tab in Xcode and my team a bundle Id is correct and it's happy with signing. At this time on my machine I am using the distribution profile.

Xcode seems not compatible with the ssh key RSA-SHA2 while trying to git clone from Azure
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?

App record creation error at validation
Hi, I developed an app and trying to publish but at the validation state i'm getting two errors. The errors as follows: (1) App record creation failed due to an invalid input. Request failed with the error code "STATE_ERROR.APP_CREATE.PLATFORM_NOT_ALLOWED_DUE_TO_CONTRACT_STATE", and reason "One or more platforms cannot be created for this app due to your provider's contract state. Creation of apps for the platform(s) iOS is not available due to your provider's contract state." (2) App record creation failed due to an invalid attribute. Request failed with error code "ENTITY_ERROR.ATTRIBUTE.REQUIRED", and reason "The provided entity is missing a required attribute You must provide a value for the attribute 'companyName' with this request" Which inputs and attributes are causing these errors? Thanks in advance.

Xcode 16 no longer sets ENABLE_PREVIEWS=YES for preview builds
Up until now, it was possible to check in build scripts via the ENABLE_PREVIEWS environment variable whether a build for a SwiftUI preview is being executed. In addition, it was also possible to conditionally compile code for SwiftUI or exclude it from compilation using this variable. This no longer works with Xcode 16 and the new SwiftUI Preview compilation! There is still the option to switch to the old system with the "Use Legacy Previews Execution" setting, but as stated in the release notes, this option will be removed at some point. Which brings us back to the old problem of not being able to exclude build scripts from preview builds and not being able to prevent certain code from being compiled / add special code for SwiftUI previews. This is a terrible situation, especially for more complex projects in which precisely the points mentioned are important for the build process. I seriously hope Apple provides us with another environment variable for SwiftUI preview builds that we can use.

Matter Media Playback Cluster
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
