The issue reproducible with empty project. When you run it and tap "Open immersive space" it takes a couple of minutes to respond. The issue only reproducible on real device with debugger attached. Reproducible other developers too (not specific to my environment). Issue doesn't exists in Xcode 16.
Afer initial long delay subsequent opens works fine.

This bundle is invalid. The IPA format requires a top-level directory named Payload, containing only a .app bundle and optional plugins in a Plugins directory. (ID: df59dbe4-17e5-4bc6-9c69-8645672320(4))
when launch my app from the Xcode 26 beta on iOS 16 I get this crash:

Hi everyone,
I’m currently unable to view crash logs in Xcode Organizer for any of the apps in my account. When I try to access crash reports, I receive the following error:
"An error occurred preventing Xcode from downloading version information from App Store Connect. An unexpected error occurred: [<__NSDictionaryM> valueForUndefinedKey:]: this class is not key value coding-compliant for the key [App Name] [Version] (iOS App)."
The error message references an app name and version that were previously used. Notably, the original app name included an @ symbol (e.g., @ExampleApp). We suspected this might be contributing to the issue, so we updated the app name to remove the symbol. However, the error persists and still references the old name.
Has anyone experienced something similar or found a workaround? Any guidance would be greatly appreciated!
Thanks in advance.
During regular use, RealityKit generates an excessive amount of internal logging that is not actionable by third party developers. When developing an iOS RealityKit/ARKit app, this makes the Xcode console challenging to use for regular work.
(FB19173812)
See screenshots below.
Xcode does have an option for filtering out logging from specific SDKs, but enabling this feature to suppress the logging of RealityKit and related SDKs like PHASE is something developers have to do dozens of times each day. After a year of developing a RealityKit app, this process becomes frustrating.
If SDKs like Foundation, UIKit, and SwiftUI generated as much logging as RealityKit and related SDKs, Xcode's console would be unusable.
Is there any way to disable the logging of RealityKit and PHASE permanently?
Thank you for any help you provide.
Hello,
I have recently been using the new Power Profiler tool introduced in Xcode 26 to analyze the power consumption of my app. My app primarily operates in the background. During a profiling session of 5 hours and 30 minutes, I observed that the app was active in the background for 2 hours and 30 minutes, while it remained in a suspended state for the remaining 3 hours.
While the Power Profiler allows me to identify spikes in CPU, networking, and other resource usage at specific points, it is difficult to determine whether these values are objectively considered high.
For example, in my case, the total QoS Execution Time of CPU Impact recorded during the 5 hours and 30 minutes was 12.18 seconds. I am wondering whether this is considered a good metric.
Could you please advise on the following points?
1. Is there a commonly accepted or recommended ratio between app active time and CPU time that developers should aim for?
2. Are there any guidelines or reference materials on how to interpret CPU usage and other resource metrics for apps that primarily run in the background?
Any insights or advice would be greatly appreciated.
Thank you.
Hello guys, I’ve been recently trying to learn how to implement in app purchases and in every tutorial they create store kit configuration file but in my Xcode there is no such option - I even uninstalled my Xcode and installed 16.4 release version - still missing
And when I try to create this file manually, naming it something.storekit I get “The operation couldn’t be completed. (IDEStoreKitEditor.IDEStoreKitEditorConfigurationError error 0)” but such error isn’t documented anywhere :(
Few people mentioned that restarting Xcode fixes the problem for them, but that is not the case for me, I'm having this problem on both Xcode 16.3 and 16.4 and nothing seems to fix it - it's really frustrating
Any help is greatly appreciated
I'm not seeing the Accessibility or Attributes Inspectors in Xcode 26. Were these features removed?

Xcode 26
Has anyone else discovered that Xcode 26 will not open any files that aren’t code? None of my project’s Storyboard, Launch Screen, Assets, built targets, Info plist will open when I click them in the Project Navigator… I just get a blank white screen in the main pane. They still exist, however: I can build my project just fine, using the pre-existing configurations and Storyboard.
I’ve discovered a workaround, such as it is: I can open my project back in Xcode 16 to edit my Storyboard, and then open it once again in Xcode 26 to build the project. This works, but as you can imagine, it’s a PITA. I’m also not able to access any Xcode 26 improvements to the Interface Builder, if there are any.
Has anyone else experienced this? Or even fixed it? I can report it as a bug but I'm surprised that I haven't even found anyone else encountering this yet.
Hey everyone,
Just wanted to share a critical issue we’ve encountered while testing our app on iOS 18 simulators and devices using Xcode 26 Beta 3:
Crash Details
We're seeing the following fatal exception during launch:
NSInvalidUnarchiveOperationException
Could not instantiate class named _TtGC5UIKit17UICoreHostingViewVCS_21ToolbarVisualProvider8RootView_ because no class named _TtGC5UIKit17UICoreHostingViewVCS_21ToolbarVisualProvider8RootView_ was found...
The crash originates from Storyboards/XIBs that include a UIToolbar. It appears UIKit is referencing an internal SwiftUI-related class (UICoreHostingView), which isn't present at runtime — leading to immediate crashes.
Affected:
Apps using UIToolbar in Storyboards or XIBs
Running on iOS 18 (Simulators or Devices) and below
Built using Xcode 26 Beta 3

Thanks!
When I build the app, a block symbol appears on the app icon in the Debug Area at the bottom. What is the reason for this?
Does anyone have this issue of Xcode 26 Beta 4 crashing on closing of their project?
Currently running on macOS 26 Beta 4 on a MacBook Air M2 with 16GB of ram.
Each time i close a project, Xcode 26 Beta 4 will crash. The window pops up to send a report. Opening Xcode 26 Beta 4 will reopen the previous project. If you have multiple projects opened, all these projects will always reopen.
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.
After updating to Xcode 26 Beta 4, I can no longer upload my app to App Store Connect due to a WatchKit icon validation error.
The error states:
Invalid Icon. The watch application 'YourApp.app/Watch/YourWatchApp.app' contains an icon file 'Icon Image-AppIcon-watch-1024x1024 @1x.png' with an alpha channel. Icons should not have an alpha channel.
• This file name doesn’t exist in the asset catalog or project source.
• All icon assets used in the Watch App’s AppIcon set, including the required 1024x1024 icon, were checked with sips -g hasAlpha and confirmed to not contain an alpha channel.
• Project was cleaned, derived data cleared, and archive recreated multiple times.
• This issue only began after updating to Xcode 26 Beta 4. In the previous versions, everything was ok.
Is anyone else experiencing this after upgrading Xcode to Beta 4? Any idea/workaround on how to solve this would be appreciated.
Hi everyone,
I’m testing our SwiftUI app on both Xcode simulator and a real iPhone. On the simulator, everything looks clean and aligned. But when I run it on an actual iPhone (same build, iOS 18), the layout looks broken—fonts overlap, spacing is off, and elements are misaligned.
Both screenshots are from the exact same screen and time. First is simulator, second is iPhone.
Any idea why this difference happens? Is there something I should check in terms of rendering or layout settings?
Thanks in advance!
Hi,
In Xcode 16.4, the atomic_flag() method can be used, but in Xcode 26.0, it is not available. An error message saying Cannot find 'atomic_flag' in scope is displayed. This can be reproduced simply by trying to use atomic_flag() in a newly created empty project.
Thank you.
Xcode: Version 26.0 beta 4 (17A5285i), macOS: 15.5(24F74)
import SwiftUI
struct ContentView: View {
var body: some View {
VStack {
Image(systemName: "globe")
.imageScale(.large)
.foregroundStyle(.tint)
Text("Hello, world!")
}
.padding()
.task {
_ = atomic_flag()
}
}
}
Xcode 26 beta 4 and iOS 26 beta 4 unable to build: facing issues in sideloading using Xcode
Unable to find a DDI that can be used to enable DDI services on the device
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

Trying to publish my .NET MAUI app via the transporter after migrating it from Xamarin (using the App Store Connect feature directly within visual studio 2022 has never worked for me) and getting this error.
Validation failed (409)
Missing required icon file. The bundle does not contain an app icon for iPhone / iPod Touch of exactly '120x120' pixels, in .png format for iOS versions >= 10.0. To support older versions of iOS, the icon may be required in the bundle outside of an asset catalog. Make sure the Info.plist file includes appropriate entries referencing the file.
I have setup my maui app to use the asset catalog with the .pngs setup as bundled resources and I have also tried using the .svg method, both resulting in this error.
When I zip and unzip my .ipa file I can see the asset catalog as part of the payload (C:\Archives\AIM_MAUI\Payload\AIM_MAUI.app\AppIcon.appiconset)

I have tried manually using the actool tool from Xcode 16.4 to create the Assets.car file that is seeming to be missing and leading to this issue but even that can't compile the icons (or even a simple sample appicon.appiconset from Xcode with a singular .png added) and I am beginning to think there's an issue with the actool itself. I have tried reinstalling Xcode and every time the actool is just a partial download or a stub of the tool and not the real tool (actool size on my Mac is only 170kb and per my research it should be at least a couple mb)
Is there any workaround?
