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?

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.

Is simulator run time for Xcode 26 Beta 5 not given out yet?
However I am able to download simulators on Apple Silicon macs with same Universal installer.
Has anyone faced similar issue?
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.
I have a MacMini M2 machine running Sequoia 15.1 OS. On this machine, I am running a Virtual Machine, utilizing the Virtualization.Framework, with the same OS version, 15.1.
Logging into my account in the System Settings is successful. Next, I need to add my account in Xcode 16.1. While the initial login is successful, Xcode immediately displays the following error:
Decoding Error.
There was a failure decoding response: (HTTP 401, 60 bytes) The data couldn’t be read because it isn’t in the correct format.
As a result, I cannot see any account information, teams, etc.
A very similar bug has been reported at this issue - https://developer.apple.com/forums/thread/759877, but there has been no progress or updates there.
Is there any chance to fix this and get it working?
After updated to Tahoe 26.2 and Xcode 26.2 it seems to have forgotten the Model Provider I had configured. I create a new Model Provider and it works fine, until I exit Xcode. When I open Xcode again my Model Provider is gone.
It all worked fine before I did the updates of MacOS and Xcode.
Hello everyone! I found that the Xcode Cloud workflows under my project are completely stuck. The tasks that are already running cannot be completed. Newly started tasks remain in the queued state forever and cannot be canceled. They are consuming my usage quota 😢. Has anyone else encountered the same issue?
My company's app has a few widgets and a couple of them we do not want to show up on CarPlay due to safety concerns when iOS 26 releases. I understand Apple's recommended way to prevent users from using your widget in CarPlay is to use the .disfavoredLocations([.carPlay], for: [.systemSmall]), and this puts your widget in the 'Other' section of the widgets.
https://developer.apple.com/download/files/CarPlay-Developer-Guide.pdf
However, this .carPlay widget location is only available in Xcode 26, and our app cannot be built on Xcode 26 yet due to some build errors. We are able to fix those build errors in a separate branch, but we won't be doing our official release builds on Xcode 26 until it is out of beta, which is usually right before iOS 26 officially releases to general audiences. We release our app versions on a monthly cadence, so the version that will be out when iOS 26 comes out is already in testing.
Is there any existing way we can disable this widget on CarPlay so it does not appear to work when tapped? Currently, it opens our CarPlay app, but the CarPlay app does nothing with it. On the iPhone, when you tap the widget it opens our app and performs a function.
We don't wan't to disable it on the iPhone, just when it's on CarPlay. We don't have time before the app release to implement the same functionality on our CarPlay app. I haven't found any reliable way to detect if the widget is running in the CarPlay location versus the iPhone home screen.
Thanks in advance for any assistance.
We are getting unreliable results on XCode Cloud tests. I'm not sure if it's related to the current service outage.
I'm running a very simple XCTest UI suite, on some devices it succeds and it others it fails to start. I'm not getting a userful error message.
MyApp-Runner encountered an error (Failed to prepare device 'iPhone 16 Pro Max' for impending launch. (Underlying Error: Unable to boot the Simulator. launchd failed to respond. (Underlying Error: Failed to start launchd_sim: could not bind to session, launchd_sim may have crashed or quit responding)))
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

Hello,
I am writing this post because the Apple Developer Program enrollment process is clearly malfunctioning, and I have reached a point where this situation is unacceptable.
First payment
I initially purchased the Apple Developer Program on December 3rd, 2025 at 16:03 (Turkey time).
The payment was fully completed, confirmed by my bank, and I received the official Apple Store receipt.
• Order ID: W1557478965
• Amount: 1029 TRY
• Status: Completed / Posted
Despite this, my account continued to show:
• “Purchase your membership”
• Enrollment status: Pending
• No access to App Store Connect
After several days with no response from Apple Support and no activation, I assumed something had gone wrong on Apple’s side.
Second payment
Because I was completely blocked and received no reply from support or the forums, I made a second payment to rule out any payment failure.
• Order ID: W1694587309
• Amount: 1029 TRY
• Status: Completed / Posted
Current situation
At this point:
• Two separate payments
• Two unique Apple Store order IDs
• Zero activation
• Zero response from Apple Support
• Enrollment still Pending
• App Store Connect still inaccessible
Support case details:
• Apple Support Case ID: 102769533427
• Multiple follow-ups sent
• No reply
• No action taken
This is no longer a delay — this is a system-level failure.
I have paid twice for a single Developer Program membership and received nothing in return: no activation, no explanation, and no support.
I am formally requesting manual intervention by Apple staff to:
1. Immediately activate my Apple Developer Program membership
2. Investigate and resolve the duplicate payment (refund or clarification)
3. Explain why a paid enrollment can remain blocked with no support response
If this forum is monitored by Apple employees, this issue requires urgent escalation.
This situation should not happen in a paid developer program.
Thank you.

ChatGPT in Xcode 26.1 is super slow for me. What used to complete in a batter f seconds is now taking tens of minutes.
Context: M2 Pro MBP, Xcode 26.1, macOS 26.1. CPU stays under 50% while ChatGPT returns. Using the minimal setting. Tried restarting, have verified I have nothing running Electron, no other apps are running.
ChatGPT returns fast for the displayed content but the preview window where it renders code per line takes a few seconds per line.
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.

In previous versions of the simulator, it was possible to import files into the Files app by dragging them from the Finder into the Simulator. It appears that in the iOS 26 Simulator, this opens the file in Safari.
I've only tried it with .json files so far.
The documentation at https://developer.apple.com/documentation/xcode/sharing-data-with-simulator says that the original behaviour should happen:
To add files to Simulator, select one or more files in Finder on your Mac, then click the Share button. Select Simulator from the share destination list. Choose the simulated device from the drop-down list. Simulator opens the Files app, and lets you select where to save the files.
I'd love to learn if this is intentional behaviour, and if so, what workarounds there might be. I use this pattern quite a lot, as I have a HealthKit app, and I've built a system that allows me to export workouts as JSON files from a real device, that I can then import into a simulator for testing.
Edit: I found a workaround. Make a folder in Files.app, then search for it within ~/Library/Developer/CoreSimulator/Devices. Open the folder in Finder, then add any files you want to be available in the Simulator.
Hi everyone!
Writing this from my personal Developer Account but this is related to my other account, enrolled under my startup organization account.
Sunday morning I've started finalizing a feature on my startup that I've worked on with my colleagues for over a year already. I've pushed the code as usual, wanted to do a internal TestFlight build and I was apparently logged out on Xcode from my account. Thought it's no big deal - went to log in in Xcode Settings -> Account but my attempt was unsuccessful - I was presented a message stating "Unknown error occurred".
Weird, but then I tried to use the browser to login into App Store Connect using the following account - I was met with the same message. Alright, I thought I might need to reset my password - clicked on Forgot Password and started the reset password flow.
To my surprise, I am presented a new message, stating - Your account has been locked and I need to verify my phone number to request access to this account. I proceed, enter my phone number associated with the account and click continue.
I am the presented with the message that my Account Access is Requested and I need to wait up to a day.
I then also decided to check Keychain and well, surprise surprise - all my certificates have also been revoked from keychain, both development and distribution.
Well, I wake up this morning to the following email:
And attempting to login/reset password now presents a message stating that my account is now LOCKED:
I've been an Apple Developer for more than 7 years. I've had multiple Developer accounts. This is the first time I'm seeing such things. Please, someone explain what is going on and how can I verify my identity with apple to access my account?
I cannot release a new version of our startup's app. We are suffering business losses due to failing to meet a deadline with a potential client. I cannot believe such things are happening.

Hi folks,
I've been having this issue for the last few months, where Xcode Cloud fails to resolve Swift package dependencies while compiling my builds, seemingly at random.
Some of my Xcode Cloud builds will fail after several minutes, with an error log looking like that :
xcodebuild: error: Could not resolve package dependencies: failed downloading 'https://dl.google.com/firebase/ios/bin/grpc/1.62.2/rc0/grpcpp.zip' which is required by binary target 'grpcpp': downloadError("The request timed out.")
Whenever this happens, I have to manually restart an Xcode Cloud build process (or several builds, since the error can happen multiple times in a row), to the point it's becoming increasingly painful to rely on Xcode Cloud for my workflow.
The failing packages are mostly random (meaning, it's not always the same one that Xcode fails to resolve), but they are always publicly accessible, even though I have an environment variable set in my Xcode workflows to retrieve a single Github private dependency (maybe this has some kind of importance).
Could anyone tell me if this is an isolated issue, or if I could do anything on my end to resolve this ?
Thank you !

Hi,
I just migrated from Xcode 15 to Xcode 16.3 RC. When I run my app on any simulator, iOS 17 or iOS 18, I seeing strange behavior the second time I launch the app. The app uses a few frameworks, such as Firebase Crashlytics, and the network calls all work fine on the initial launch. however, subsequent launches consistently get the following error:
Task <17ACD3D4-FB31-4091-A797-D573F31909C2>.<2> finished with error [-1001] Error Domain=NSURLErrorDomain Code=-1001 "The request timed out." UserInfo={_kCFStreamErrorCodeKey=-2102, NSUnderlyingError=0x600000c46910 {Error Domain=kCFErrorDomainCFNetwork Code=-1001 "(null)" UserInfo={_kCFStreamErrorCodeKey=-2102, _kCFStreamErrorDomainKey=4}}, _NSURLErrorFailingURLSessionTaskErrorKey=LocalDataTask <17ACD3D4-FB31-4091-A797-D573F31909C2>.<2>, _NSURLErrorRelatedURLSessionTaskErrorKey=(
"LocalDataTask <17ACD3D4-FB31-4091-A797-D573F31909C2>.<2>"
), NSLocalizedDescription=The request timed out.,
The only way to run again on that simulator is to Erase All Content and Settings. I did not see this issue in Xcode 16, and my app has been in production for over a year without networking issues.
Pushing to my phone works fine.

Any help would be greatly appreciated!
Thanks,

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.
