Hello, been beating my head against the wall for a few days with this. Originally got the error in Xcode 16, through the course of troubleshooting uninstalled and reinstalled Xcode multiple times, upgraded Xcode to 23 - same result. Create a different user on my computer and try, same result. Xcode > Settings > Components show both iOS 26.0 and iOS18.6 simulator, however no simulators show in Xcode, and Xcode hangs when you try to create one. 'xcrun simctl list runtimes' shows this: iOS 18.6 (18.6 - 22G86) - com.apple.CoreSimulator.SimRuntime.iOS-18-6 (unavailable, liblaunch_sim.dylib could not be opened) iOS 26.0 (26.0 - 23A343) - com.apple.CoreSimulator.SimRuntime.iOS-26-0 (unavailable, liblaunch_sim.dylib could not be opened). Does anyone have any ideas on what the issue could be?

After upgrading to macOS 26.0 Tahoe and Xcode 26.0.1, I’ve noticed an issue with audio playback whenever the iOS Simulator is running. Device: MacBook Pro 13" (2020, Intel, 16GB RAM, 500GB SSD) Issue: Any sound played on the Mac (system sounds, music, videos) begins to break/distort once the Simulator is active. App Sounds: If the app running inside the Simulator plays audio, that audio also breaks/distorts. Previous Version: This issue did not occur on macOS Sequoia 15 or with Xcode 16. Everything was working fine before the upgrade.

I was wondering wether you have to create your full app as an Xcode app and then translate it into playgrounds? Because some of the submissions I have seen on YouTube are running on Xcode iPad emulators.

When showing or hiding the Code Review window in Xcode 26.0.1, a loading screen appears and Xcode freezes. The loading screen appears for about 30 seconds, then disappears and the Code Review window appears. During this time, Xcode also freezes and cannot function. It doesn't seem to be an error or bug, but people who frequently switch between Code Review windows find the long loading time inconvenient. Is there any way to improve this? (MacBook Pro 16, M2 Max, 64GB memory, macOS 26.0 (25A354))

I recently installed Xcode 26.0.1. (MacBook Pro 16, M2 Max, 64GB memory, macOS 26.0 (25A354)) Normally, when debugging, a red error appears in the left-hand Issues navigation, and you can click on it to access the location of the error. However, currently, when debugging, the red error does not appear in the "Issue Navigation" on the left-hand side of the Xcode screen. There is an error, but it isn't displayed. It does appear, but disappears after 1 second. (It disappears before I can click on it.) The error doesn't appear or disappears after 1 second, so I can't pinpoint the exact location. Please help me resolve this issue. Additionally, I deleted all Xcode development-related files inside my Mac and restarted my MacBook, but the symptom still persists.

Hi, yesterday when I was trying to release the TestFlight build of my app the xcode said that it could not authenticate my apple ID. I then came to know that it actually wanted me to complete and aggrement which was "Paid Apps Agreement". This agreeemnet is to be made if one has to sell their app on AppStore or make in-app-purchases. I want to ask if it was mandatory for me to sign that agreement? As the solution which I could come across suggested that xcode blocks the distribution if there is a pending agreement.

Environment: • macOS 26.0 (25A354) • Xcode 26.0.1 (17A400) Issue: Applying .tint(...) to a macOS Liquid Glass style Toggle does not change the background color when the toggle is in the on state. Expected behavior: The .tint(...) modifier should apply the chosen color. Actual behavior: The toggle remains system blue (accent color), regardless of the tint specified Notes: I’m hearing that .tint() behaves normally on iOS, so this may be macOS-specific.

macos 26, xcode 26, ios 26. Everytime when you add new line at some point (like after 10-20 lines) the TextField will ignore the lineLimit and start changing the height. The problem related to Form but not Scroll. Maybe it can be reproduced in other scroll-based views. Bug report opened. Any siggestions? struct Test: View { @State var text = "" var body: some View { Form { Section { TextField("", text: $text, axis: .vertical) .lineLimit(3) .background(Color.green) } } } } @main struct TestApp: App { var body: some Scene { WindowGroup { Test() } } }

Lookin for J - is this a safe place for discussing full apps ive built but not submitted or shared , I have maybe over 100 but had been unaware any assistance was provided.. is there a formal process to take to submit an app fro review to improve OS, other than during App Store review.

I have two apps in which I have fixed warnings on Sendable, however there's one app where I did not and it looks like the rent's come due with Xcode 26.0, as I am getting over 100 warnings about Sendable. On a lark, I let the AI work on the warnings. There were so many that I ran out of free ChatGPT time and had to wait 24 hours. But today I cleared every remaining warning, but did the app still work? I figured I'd have to trash this code and do it by hand. But to my surprise, the app is working properly so far. More testing needs to be done and I need to dig into the code to make sure it's right, but so far, so good.

I'm experiencing a persistent iOS Simulator app installation failure when running automated tests using Appium/XCUITest. The error occurs consistently across different simulator configurations and appears to be related to metadata handling during app installation.

I tried to apply a promotional offer to a subscribed user. When I tested it in the Sandbox environment, it did not show the promotional payment popup but returned a “restored” status. However, when I tested it in the Xcode environment, it correctly displayed the payment popup, but after I tapped the Subscribe button, it showed an “Unable to Purchase” popup like this: And in the console I could see this error: Received error that does not have a corresponding StoreKit Error: Error Domain=AMSErrorDomain Code=305 "Server Error The server encountered an error" UserInfo={AMSURL=http://localhost:56862/WebObjects/MZBuy.woa/wa/inAppBuy, AMSDescription=Server Error, NSDebugDescription=Server Error The server encountered an error, AMSServerErrorCode=3903, AMSStatusCode=200, AMSServerPayload={ "cancel-purchase-batch" = 1; dialog = { defaultButton = ok; explanation = "Contact the developer for more information.\n\n[Environment: Xcode]"; initialCheckboxValue = 1; "m-allowed" = 0; message = "Unable to Purchase"; okButtonString = OK; }; dsid = 17322632127; failureType = 3903; jingleAction = inAppBuy; jingleDocType = inAppSuccess; pings = ( ); }, AMSFailureReason=The server encountered an error} Could someone help me resolve this issue?

Hello everyone, I'm encountering a frustrating issue with Xcode 26 and the iOS Simulator selection, and I'd appreciate any insight from the community. Problem Overview I have updated my Xcode to version 26.0. I have successfully installed the iOS 26 SDK and the iOS 26 Simulator runtime via Xcode's component settings. However, when I open an older, existing project, the device selection dropdown menu does not list the iOS 26 simulator. I can only select older versions, such as my locally installed iOS 18.6 simulator. Key Finding (Diagnosis) New Project Test: When I create a brand new Xcode project, the iOS 26 simulator is correctly available and runs as expected. Conclusion: This strongly suggests the issue lies with a specific configuration setting in the existing (old) project, rather than the Xcode installation itself. Troubleshooting Steps Taken I suspect a project-level configuration is somehow blocking the display of the new simulator. I've already checked: General -> Deployment Target: This is set to an older version, but theoretically shouldn't hide the simulator list. Build Settings -> Base SDK: This is set to the latest iOS SDK. Has anyone else experienced this behavior when upgrading projects to support iOS 26? What specific configuration files (e.g., .xcodeproj settings, Podfile configurations, or specific Build Settings) should I check to ensure my old project properly recognizes and displays the newly installed iOS 26 simulator? Any pointers or solutions would be greatly appreciated! Thank you.

Hi everyone, have any of you tried running an app from Xcode 16.x (during development, running on device) on one of the iPhone 17 models? I'd like to know whether it still works or if someone would need to update to Xcode 26 for that to work.

Does Xcode 26 still support creating pull requests and/or viewing comments from GitHub pull requests associated with the current branch? This used to be possible, but I cannot get it to work with the current version of Xcode (26.0.1). The "Create Pull Request" menu item takes me to github.com directly, instead of presenting a nice UI menu; hence I'm wondering.

Hi, as described by the subject, I'm trying to find a way to remove the preinstalled iOS support via command line tool. I need to do that because I need to use the universal architectureVariant in order to build on old Intel-based iOS Simulators, but on iOS 26. As described in this page, I can use this command to download the architecture I need xcodebuild -downloadPlatform iOS -architectureVariant universal however, launching this command I receive this error iOS is already downloaded as arm64Only. To replace with universal, first delete the existing one. Is there any way to remove the current installed iOS platform via command line? In particular I'm serching for a way to do what the button "Delete" in the attached screen does. Thank you

Hello everyone and thank you for you're time! I got an issue with uploading several icons to testflight. I'm using Game Maker Studio as my engine for the game. This is the error that I'm getting, even when I try to use the old icons for the game, that worked in the past. I tried to transform the icons, using this site "https://makeappicon.com/", but I still got the same validation error. Can you help me fixing the issue - thank you so much!

In iOS 26 When we download any DRM content first time it is downloading again when we edit audios and Video Quality and start downloading it is freezing complete app. Neither it is crashing not giving any error.

When I try to build my project with Xcode 26.1 beta (17B5025f) it freezes a lot. The steps are as follows: Open my project with the aforementioned Xcode Start a build of one of my schemes Open a browser or any other app above the Xcode window Try to present the Xcode window on the foreground Result: Xcode freezes I cleared the Derived Data and it still happens

When adapting to iOS 26, do not use Liquid Glass by adding an option to the Info.Plist file: UIDesignRequires Compatibility with a value of YES. But there is a question: 'Note that this option will be removed in Xcode 27, so it can only be delayed for a maximum of one year.' May I ask if this question is true
