I have designed a new icon for my app/Tahoe in Icon Composer (launched from within Xcode)but I simply cannot get it to show up. The documentation for Icon Composer spends a lot of time describing how to design the icons but goes distressingly vague/silent on how one might use it. It suggests that I should drag the file to Xcode and it will guide me as to where to put it.
The app continues to use the old (pre-Tahoe) icon.
I don't get any change of behaviour and I don't know what to name the file. I assume that there are no other settings that I have to change. I can't find anything on the web or in Apple's documentation: maybe I'm missing something obvious!
My app is a working NSDocument-based Cocoa project.
Any suggestions please.

Hi!
In neither Xcode 16.2 beta 3 nor Xcode 16.2 I am able to get App Shortcuts Preview to recognise my Shortcuts. In either supported language I always get "No Matching Intent" as the result.
Flexible matching is enabled, minimum deployment target is iOS 18. The Shortcut phrases do work in the simulator and on device.
Is this a known issue or am I missing something?
At the Platform State of the Union, Apple demoed clicking a ✨ button in the Xcode toolbar to use Apple Intelligence in Xcode.
I don't see that button in Xcode Version 26.0 beta (17A5241e). Am I missing it? It's supposed to be in the upper-left corner, right?
Do I need to turn it on or something? I'm on macOS 15.5 Sequoia, on a 16-inch, 2021 MacBook Pro
Hiya folks! I'm David and I work on rust-analyzer, which is a language server for Rust similar to sourcekit-lsp. I'm using the new Instruments profiling tooling functionality in Xcode 16.3 and Xcode 26 (Processor Trace and CPU Counters) to profile our trait solver/type checker. While I've been able to use the new CPU Counters instrument successfully (the CPU Bottleneck feature is incredible! Props to the team!), I've been unable to make use of the Processor Trace instrument.
Instruments gives me the error message "Processor Trace cannot profile this process without proper permissions". The diagnostic suggests adding the com.apple.security-get-task-allow entitlement to the code I'm trying to profile, or ensure that the build setting CODE_SIGN_INJECT_BASE_ENTITLEMENTS = YES is enabled in Xcode.
Unfortunately, I don't know how I can add that entitlement to a self-signed binary produced by Cargo and I'm not using Xcode for somewhat obvious reasons.
Here's some information about my setup:
Instruments Version 26.0 (17A5241e)
I'm on an 14" MacBook Pro with M4 Pro. It's running macOS Version 26.0 Beta (25A5295e).
I've enabled the "Processor Trace" feature in "Developer Tools" and even added the Instruments application to "Developer Tools".
As a last-ditch effort before posting this, I disabled SIP on my Mac. Didn't help.
To reproduce my issue:
Get Rust via https://rustup.rs/.
Clone rust-analyzer: git clone https://github.com/rust-lang/rust-analyzer.git.
cd rust-analyzer
Run cargo test --package hir-ty --lib --profile=dev-rel -- tests::incremental::add_struct_invalidates_trait_solve --exact --show-output. By default, this command will output a bunch of build progress with the output containing something like Running unittests src/lib.rs (target/dev-rel/deps/hir_ty-f1dbf1b1d36575fe).
I take the absolute path of that hir_ty-$SOME-HASH string (in my case, it looks like /Users/dbarsky/Developer/rust-analyzer/target/dev-rel/deps/hir_ty-f1dbf1b1d36575fe) and add it to the "Launch" profile. To the arguments section, I add --exact tests::incremental::add_struct_invalidates_trait_solve.
I then try to record/profile via Instruments, but then I get the error message I shared above.
Below is output of codesign -dvvv:

Any tips would be welcome! Additionally—and perhaps somewhat naively—I think I'd expect the Processor Trace instrument to just work with an adhoc-signed binary, as lldb and friends largely do—I'm not sure that such a high barrier for CPU perf counters is warranted, especially on an adhoc-signed binary.
I'm getting EXC_BAD_ACCESS (code=2, address=0x7ff8a6e2fcce) when launching my app on the simulator with Address or Thread Sanitizer enabled. I'm running Xcode 16.3 (16E140) on macOS Sequoia 15.4.1 (24E263). The call stack looks like the following.
On the device, there is no crash, but this message is printed to the console:
malloc: nano zone abandoned due to inability to reserve vm space.
(Not sure if it's related.)
Does anybody know what is causing the crash?

Hi all,
I’m an Admin user in an Apple Developer Program (Organization) team, but I’m unable to access Certificates, Identifiers & Profiles (CIP) on developer.apple.com. I’d like to understand what permission is missing and where it should be enabled.
Context
Program type: Apple Developer Program (Organization)
My role in App Store Connect: Admin
I can access App Store Connect normally, but CIP resources on developer.apple.com are blocked.
The Account Holder can access CIP normally.
What I see (Problem)
In the Apple Developer portal → Certificates, Identifiers & Profiles, I get:
“Access Unavailable — You currently don't have access to this membership resource. Contact your team's Account Holder or an Admin.”
In Xcode → Settings → Accounts → Team, the “Certificates, Identifiers, & Profiles” section shows a red error indicator and doesn’t load.
Only my account is affected; the Account Holder is not.
What we’ve tried / confirmed
Membership is active (renewal date is valid)
Signed out/in of Xcode and re-added my Apple ID
Confirmed selecting the correct Organization team in Xcode / Developer portal
Account Holder confirmed they can access CIP
Questions
For an Organization team, what exact permission(s) are required for a member to access Certificates, Identifiers & Profiles?
Where is this access controlled — App Store Connect → Users and Access vs developer.apple.com → People?
If Admin in App Store Connect is not sufficient, what additional role/setting is needed to grant CIP access?
I have an AppleTV app which I released in 2016. I've updated it and released a new version every year without much hassle.
This year, with tvOS 17.2, the layered app icon isn't working right. This is a two-layer image made with PNGs.
When it's selected, it looks right and the layers move correctly:
But when it's not selected, the background layer disappears:
Screenshots are from the simulator but it also happens on the device. It's inconsistent; sometimes it's the front layer that disappears. Occasionally both layers work, but I can't tell why.
I've spent a day trying everything. Very frustrated.
The icon previews correctly in Xcode and in Parallax Viewer.
The image sizes are correct: 400 x 240 for Small, 800 x 480 for Small@2x, 1280 x 768 for Large.
The back layer is a non-transparent PNG.
I tried adding a Large@2x set. Didn't help.
Originally I had a three-layer image with no middle layer PNG. I deleted the empty middle layer, but that didn't help.
All the PNG files are from GnuIMP. Same color space, even.
I was using the filenames tvicon-back-s.png and tvicon-back-s@2x.png. I tried taking out the @ sign in case that was confusing Xcode. (It never has before, but I am flailing here.)
Anybody have any clues? If it's an Apple bug and there's nothing I can do, I'm going to just push the release button and hope it fixes itself someday.
I applied for the Apple Developer Program on Jan 29th, but my enrollment is still pending with no updates. This delay is really affecting my project timeline since I need to start my app soon, and I can’t move forward without my account being approved.
I’ve already reached out to Apple Developer Support, but I haven’t gotten any clear response on when it will be completed. tried even calling the support line but they couldn't help with developer accounts. Has anyone else experienced similar delays? If so, how long did it take for your account to get approved?
Would appreciate any advice or insights! Thanks in advance.

I'm currently exploring Instruments for profiling and tracing on macOS 15.6.1. I know there is the "network connections" instrument which records TCP/UDP information, however it seems to not include the "lo0" (loopback) interface.
Is there a way to configure it so that localhost traffic is included in the recording? as the application I'm tracing uses that and I want that information to be included in traces.
The documentation for network-interface-detection schema makes no mention of how it detects interfaces.
Thanks in advance.
When I try to get a new API Key I get the following error.
"API Keys cannot be created due to an invalid Program License Agreement. Please update this agreement and try your request again."
I have been to the agreement section, and it says:
"Issued October 8, 2025. Accepted November 19, 2025."
Any idea why I still get this error??
Not sure if that makes a difference. I had a paid account, but I didn't renew it because I don't need it anymore, and I was told that I can still use this account for free for app testing.
I downloaded the latest version of Xcode 26 (beta). I'm running Max OS 15.5. How can I use Claude 4 Opus? I can't wait to try this out. Thanks in advance!

My project build failed in Xcode Cloud(works well in my local Mac), and the error shows: Preparing build for App Store Connect failed
The error message is not clear enough to help us find the solution to fix it. Can anyone help with it?
ITMS-90078: Missing potentially required entitlement - Your app, or a library that’s included in your app, uses Apple Push Notification service (APNs) registration APIs, but the APS Environment Entitlement isn’t included in the app signature’s entitlements. If your app uses APNs, make sure the App ID is enabled for push notifications in Certificates, Identifiers & Profiles, sign the app with a distribution provisioning profile that includes the APS Environment Entitlement, and upload a new build to ensure that push notifications function as intended. For details, visit: https://developer.apple.com/documentation/usernotifications/registering-your-app-with-apns.
Hello!
When launching/debugging on my iPad and iPhone I keep getting the following error:
“Previous preparation error: Failed to find a DDI … Run ‘devicectl list preferredDDI’ …”
I believe this was caused by a previously interrupted Xcode update around June due to low disk space, which may have left DeviceSupport/DDI/CoreDevice files incomplete. Even after finishing the update later, the error persists. I now use a new Mac with 4 TB of storage, but the issue still occurs.
Since then I have unfortunately been blocked from testing or presenting my app on devices. It seems that only a new, fully completed Xcode update might resolve the problem.
Tried so far:
– Cleared caches (CoreDevice/Devices)
– Reset trust on device and re-paired
– Checked devicectl list preferredDDI
I would really appreciate guidance, as at the moment I cannot present my app due to this blocking issue.
Thank you very much for your support!

Hi everyone, (you can answer in french)
I’m french-rookie in xcode, and I have a problem:
I’m trying to choice my custom font to add it in my Main.storyboard button, but it not works.
I have my « Font provided by application » line in my Info.plist, with the name of my font in [0]
(See images below)
When I’m on storyboard button, I chose « custom » in font selector, then display font list but my custom font doesn’t appear.
I already tried to install the font in my mac, but still stucked, nothing change 😭
Could you help me please?
Thanks a lot
(I specify that I scrupulously followed the way of doing explained on the Apple official page:
Adding a Custom Font to Your App )
Hi there,
We’re encountering this error in all of our builds when using the latest Xcode and macOS:
The Metal Toolchain was not installed and could not compile the Metal source files. Download the Metal Toolchain from Xcode > Settings > Components and try again.
In short, all builds are failing. I’ve tried fixing this by installing Metal and applying other solutions, but none of them worked reliably.
Is there a way to ensure that the Metal Toolchain is installed on the CI machine?

ProductName: macOS
ProductVersion: 26.0.1

I am using SwiftData for my model. Until Xcode 15 beta 4 I did not have issues. Since beta 5 I am receiving the following red warning multiple times:
'NSKeyedUnarchiveFromData' should not be used to for un-archiving and will be removed in a future release
This seems to be a CoreData warning. However, I am not using CoreData directly. I have no way to change the config of CoreData as used by SwiftData.
My model just uses UUID, Int, String, Double, some of them as optionals or Arrays. I only use one attribute (.unique).
I tried to post a reply to a thread. It seems to be posted, but does not appear in the thread once sent…
why xcode has no option to fold all
