After updating from Xcode 16 to the new Xcode 26 beta 3, running my iOS app becomes slow to the point of unusable. It builds and installs fine, but when running with the console, it lags about 20-50x compared to building and running with Xcode 16. I wanted to try our Xcode 26 to preview my new app icon made in icon composer but now I don't think it's worth the hassle.
When running via simulator, the same performance issues. Anybody also struggling with slow on-device testing speed? I am on Sequoia 15.5.

Hi there,
I recently updated to the latest version of macOS Tahoe 26.3.
Since then, Xcode is not able to resolve my Swift Package dependencies anymore. We use SSH for all our Github hosted packages. When package resolution is running, we randomly have Failed to verify SSH fingerprint on some remote package.
Nothing has changed and it worked perfectly with Tahoe 26.2. The SSH have been reconfigured and known hosts have been verified.
Is something changed between those 2 versions or is it a bug ?
Hi everyone,
I’m unable to enable Xcode Cloud for any app on my account.
At the final step of the Xcode workflow setup (“Confirm App on App Store Connect”), pressing Complete always returns:
“ could not be added to Xcode Cloud. Authentication credentials are invalid.”
This affects both existing apps and completely new test apps with fresh bundle IDs.
What I’ve verified
• I am Account Holder and Admin.
• All agreements are accepted.
• App creation, bundle ID registration, and certificate management work normally.
• I’ve removed/re-added my Apple ID in Xcode and cleared all Xcode-* tokens from Keychain.
• Test apps in clean Git repos reproduce the same error.
Support
I have already opened Case ID 102769512657 with Apple Developer Support, but I’m posting here in case others have seen this issue or know of additional steps to confirm the provisioning state.

Hello Team
I tried to enroll using the Apple Developer app on both my Mac and my iPhone and I keep getting the "Unknown error" please try again popup.
I'm on the latest macOS and iOS version, have everything in line to the requirements, but nothing seems to be working.
Can someone guide me if there's something I've not done right?

Hi,

Environment:
Swift Playgrounds (macOS)
SwiftUI App Preview
macOS version: 26.2 (25C56)
Issue:
In Swift Playgrounds on macOS, the app repeatedly shows the system permission dialog:
“My App would like to access data from other apps.
Keeping app data separate makes it easier to manage your privacy and security.”
Steps to Reproduce:
Create a new SwiftUI app in Swift Playgrounds.
Run the SwiftUI App Preview.
When the permission dialog appears, click “Allow”.
Expected Result:
The permission should be granted once and persist, allowing the preview to continue normally.
Actual Result:
After clicking “Allow”, the SwiftUI App Preview crashes and restarts.
When the preview restarts, the same permission dialog appears again.
This repeats indefinitely, creating a loop.
Notes:
This occurs even when no explicit file system or inter-app data access code is written.
The permission choice does not appear to persist between preview restarts.
Question:
Is this a known limitation of Swift Playgrounds sandboxing or SwiftUI App Preview?
Is there an official workaround or recommended approach to avoid this behavior while using Swift Playgrounds?

Hi There,
I´m From Spain with an LLC Company in the USA.
Is a Disregarded company, the problem is that when I try to set up the paid apps agreement, Apple display the form W-9 instead of Form W8-BEN (that is for non-us resident)
My question is... is this right?
Under the name of my company, appear an option that ask me ...
"Who is the Beneficial Owner? "
You can choose between : Individual, Limited Liability - Disregarded Entity, Limited Liability - Partnership, Other...
I choose Limited Liability - Disregarded Entity
I m not sure if the form W-9 is the right for me because my other online business is about selling books on amazon and there the form that I m using is W8-BEN
Hi.
I'm currently working on Xcode CI build uploading ipa to TestFlight.
Building archive is successful but exportArchive is failed with error "exportArchive Failed to Use Accounts".
How can I fix this error?
On devices and simulators with iOS 26.1, the animation does not work correctly (the initial and final screens are distorted). I use open class func transition(with view: UIView, duration: TimeInterval, options: UIView.AnimationOptions = [], animations: (() -> Void)?, completion: ((Bool) -> Void)? = nil)
with options: .transitionFlipFromRight
Hello,
I'm checking to see if anyone else is experiencing an issue downloading the latest beta simulator.
When I try to download the iOS 26 beta 5 simulator in Xcode, the download fails instantly. There is no progress, just an immediate error with no message other than the code itself: DVTDownloadableErrorDomain Code: 41.
I've already restarted both Xcode and the Mac multiple times. I have also tried downloading on different networks to rule out a firewall issue.
I Keep getting this error if I try to enroll in the developer program, why is this? Please tell me how to fix this of why this is happening!
Hi
I've downloaded the latest version of Xcode 14.2 but when I run the app in Simulator I can only test it on iOS16.2 Is there a way to run it in 16.3?
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
I'm not able to download my Private key since Yesterday and I get the following error message when I click on "Download"
Auth Key can only be downloaded once. This auth key has already been downloaded.
I revoked all my existing keys and created new ones and I get the same error message. I tried all the mentioned solutions on this forum and StackOverflow like using Safari,turning off VPNs,removing spaces from Key name, using my iPhone, using a Mac, incognito/private mode on Windows Microsoft Edge, clicking done then pressing download after, right clicking on download Linked File as...nothing seems to work
I enrolled in the Apple Developer Program on February 3, 2026. The payment was completed successfully at the time of enrollment, but my membership status has remained “Pending” since then.
So far:
No request for additional documents or identity verification
No phone call from Apple
No follow-up email other than the payment confirmation
Apple Developer Support has been contacted, but no response yet
I understand that verification can take some time, but the complete lack of communication is concerning, especially since this is blocking active development and release planning.
If this is a known backlog or system-wide delay, some transparency from Apple would help. I’d also appreciate hearing whether others who enrolled in early February are seeing the same prolonged “Pending” state.
Thanks in advance to anyone who can share recent experiences or escalation paths.
I am preparing for Swift Student Challenge, but it seems like the iPad Playground app still not support the latest SDK.
I can't use frameworks like FoundationModel, etc., directly in playground app
My playground for this year would require iPad environment since it uses PencilKit, ARKit, etc., and I also want to use the latest tech + the liquid glass UI
Right now, I develop the project as a normal Xcode project, and I am wondering how do I post it?
As Xcode playground, it must run on macOS
As Swift Playground project, the iPad version of Playground does not support latest APIs and it can't compile

I'm getting following message when launching #Playgrounds canvas with Xcode 26 beta 4.
Here are things I've tried:
Reinstall Xcode
Reinstall components
Removed derived data
Run Disk Utility to fix permissions
Tried to change Default Actor Isolation, Approachable Concurrency
Changed around settings on Schemes: Run: Options and Diagnostics
Created brand new project with default settings.
Filed FB19003005 in Feedback Assistant.
I'm surprised to see that I didn't see any posts on this during my search. So this could be isolated matter just to me.
Hello Team,
I try to delete photo from Photos for that i used this method,
[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
[PHAssetChangeRequest deleteAssets:@[assetToDelete]];
completionHandler:^(BOOL success, NSError *error) {
}];
This method pops up a dialog with Don't Allow or Delete. But some time in some iPhones not respond PHAssetChangeRequest deleteAssets method that's why that completionHandler not called because of that i can't perform any operation of PHPhotoLibrary then after.
If I restart my iPhone then it works. Many users of my app complained about this issue. I have an iPhone 11 with iOS 15.3. But some iOS 12,14,16 users also face the same issue.
So what exact issue is there? Is it related to iOS or a method?
Thanks,
Ankur
