Best Practices: Dependency management for local packages
I have a project which contains local packages. One of the packages has an explicit dependency on package A, but the main project also has the same dependency. Both of them are pinned to the exact version at all times. Should I manage "shared" dependencies at the project level for local packages? This seems counter intuitive at first, but this question is originating from me fighting with a "Build service could not create build operation: unable to load transferred PIF: The workspace contains multiple references with the same GUID" error in Xcode 16 (all versions). It happens when I switch branches. Closing and reopening Xcode does resolve the issue, but it's a real flow killer. The guide below doesn't mention dependency graph best practice. https://developer.apple.com/documentation/xcode/organizing-your-code-with-local-packages Thank in advance.

Xcode 26.2 / iOS 26.2 Simulator not downloading
Hey all, I recently updated to Xcode 26.2 and I'm having the hardest time trying to download the corresponding iOS simulator. I installed Xcode from developer downloads and the app did not come loaded with an iOS simulator. When trying to download from Components in Settings, I only get the following message: Download failed due to a bad URL. (Catalog download for com.apple.MobileAsset.iOSSimulatorRuntime) Domain: com.apple.MobileAssetError.Download Code: 49 User Info: { checkConfiguration = 1; } I also tried downloading via Terminal but also get a download failed message. I am on the latest macOS and have over 600 GB of disk space available. In previous versions, I was able to download the iOS simulator directly from Developer Downloads, but anything after 26 is not there. Any suggestions?

Metal is not installed on Xcode 26 on Xcode Cloud
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?

“Keep Going with Apps” Tutorial section will not complete.
Hello All, I am currently working through ”Keep going with Apps” in Swift Playground. The section in the tutorial “Add a DancingCreature view” will not complete. I have tried to type it is as written in the tutorial and even used the copy and paste button provided. I have restarted the app and my IPad with no success. I have attached a screen shot of the tutorial prompt. Here is the code block: import SwiftUI import Guide struct DancingCreatures: View { //#-learning-code-snippet(varDeclaration) @EnvironmentObject var data : CreatureZoo var body: some View { SPCAssessableGroup(view: self) { VStack { ZStack { /*#-code-walkthrough(dance.forEach)*/ ForEach(data.creatures) { creature in /*#-code-walkthrough(dance.forEach)*/ /*#-code-walkthrough(dance.textView)*/ Text(creature.emoji) .resizableFont() .offset(creature.offset) .rotationEffect(creature.rotation) /*#-code-walkthrough(dance.textView)*/ } } ZStack { /*#-code-walkthrough(dance.forEach)*/ ForEach(data.creatures) { creature in /*#-code-walkthrough(dance.forEach)*/ /*#-code-walkthrough(dance.textView)*/ Text(creature.emoji) .resizableFont() .offset(creature.offset) .rotationEffect(creature.rotation) /*#-code-walkthrough(dance.textView)*/ //#-learning-code-snippet(exp1) //#-learning-code-snippet(animationSolution) //#-learning-code-snippet(exp3) } } /*#-code-walkthrough(dance.onTap)*/ .onTapGesture { data.randomizeOffsets() } /*#-code-walkthrough(dance.onTap)*/ /*#-code-walkthrough(dance.onTap)*/ .onTapGesture { data.randomizeOffsets() } /*#-code-walkthrough(dance.onTap)*/ } } } } struct DancingCreatures_Previews: PreviewProvider { static var previews: some View { DancingCreatures().environmentObject(CreatureZoo()) } } Device information: IPad Pro (11 inch, 2nd gen) iPad OS Version: 26.0.1 Playground Version: 4.6.4 Anyone else come across this? Thank you in advance.

Simulator high CPU usage (CrashReport and MercuryPosterExtension)
Simply opening Simulator app (26.0) causes high CPU usage on macOS Tahoe (26.1). ReportCrash process usage is very high throughout and causes the system to heat up pretty soon. Looking into Console app for the logs found MercuryPosterExtension process is keep on crashing. (Check under Crash Reports) simctl Diagnose https://download.developer.apple.com/OS_X/OS_X_Logs/simctl_Diagnose_Logging_Instructions.pdf Share the Simulator Diagnose report while reporting, Thanks. I have raised a ticket/feedback with Apple. I request all of you to raise one too so this gets fixed soon. Apple Feedback Assistant - FB20985249

Unable to Download iOS Simulator Runtime 26.1 on Xcode — Bad URL Error (Code 49)
Hi everyone, I’m experiencing a persistent issue when trying to download the iOS Simulator Runtime 26.1 on Xcode (version 26.1). The download always fails with the following error Download failed due to a bad URL. (Catalog download for com.apple.MobileAsset.iOSSimulatorRuntime) Domain: com.apple.MobileAssetError.Download Code: 49 I’m located in Brazil, so I initially thought it might be region-related, but I’ve already tried several attempts to fix it, including: Using VPNs for the US and Europe Installing the Xcode 26.2 beta Downgrading Xcode to earlier versions Reinstalling the same version of Xcode Restarting Xcode and my Mac Switching networks Clearing simulator support/device files Unfortunately, nothing has resolved the issue. Is anyone else facing this problem? Does anyone know a workaround or a manual way to download/install the iOS 26.1 simulator runtime? Thanks in advance!

Xcode 16.3 Doesn't Remember Preview Pane Width
It seems like, by default, the preview pane tries to align to 50% of the editor pane's width. I prefer to shrink the preview pane to around ~30% of the screen so I have more space for code. This used to work fine—at least until I restarted Xcode. I never understood why the setting wouldn’t persist across sessions, but fine, that was a tradeoff I was willing to live with. However, with Xcode 16.3, it seems like Xcode forgets the manually adjusted preview pane width as soon as I switch to a different file. This has definitely impacted my productivity, as I now find myself readjusting the pane size dozens of times in a single session. Am I holding it wrong? Is anyone else experiencing this? And while we’re at it—why not make this a persistent setting so everyone can tweak the width to their liking?

Persistent 'Unknown Error' During Developer Program Enrollment from India - Support Unresponsive
Body: I am writing to report an ongoing issue with the Apple Developer Program enrollment process specifically affecting developers in India, along with significant concerns about Apple's support responsiveness in this region. Issue Summary: I have been attempting to enroll in the paid Apple Developer Program ($99/year) using the Apple Developer app on my iPhone for the past 4 days. Every enrollment attempt results in the following errors: "Unknown Error - Please try again" "Invalid Request - Service mapping to the requested URL is not available" My Setup (All Verified Correct): Apple ID Region: India Trusted Phone Number: +91 (India country code, matching my Apple ID region) Two-Factor Authentication: Enabled (genuine 2FA, not two-step verification) 2FA Devices: iPhone, MacBook Pro devices, and trusted phone number all verified Account Information: Legal name, address, date of birth, and email all updated and verified on account.apple.com Device: iPhone 17 Pro running latest iOS Troubleshooting Attempted: I have completed every troubleshooting step suggested by the community and by Apple Support myself: ✅ Verified genuine Two-Factor Authentication is enabled ✅ Confirmed Apple ID region matches trusted phone number region (+91) ✅ Updated all personal information (legal name, address, email) on account.apple.com ✅ Force restarted iPhone multiple times ✅ Uninstalled and reinstalled Apple Developer app ✅ Signed out and signed back in with correct Apple ID ✅ Tested on both WiFi and cellular data ✅ Waited 48+ hours between attempts None of these steps resolved the issue. Support Response Issues: This is where my frustration peaks. I have attempted to contact Apple Support multiple ways: Phone Support: Shows "Phone support is currently unavailable" (though it was available last week) Email Support: Submitted via developer.apple.com/support → No response for 4 days Previous Contact: Had contacted support last week, but the troubleshooting steps provided did not resolve the issue Current Status: No follow-up communication or resolution path from Apple Known Issue in India - Why This Matters: I have researched this extensively and found multiple threads in this forum (dating back months) with developers in India reporting identical errors during enrollment. To date, I have not found a single resolved thread with a working solution. This indicates: This is a documented, recurring issue affecting Indian developers specifically Apple appears to have backend infrastructure issues specific to India Support has not provided a resolution path despite multiple reports The Real Problem: Apple's Developer Program enrollment system appears to have specific bugs or limitations that prevent developers in India from successfully enrolling, yet: Support responsiveness is severely lacking There is no documented workaround or known resolution The support team seems unaware of or unprepared to handle this region-specific issue My Request: Acknowledgement from Apple that this is a known issue affecting India-based developers A concrete resolution path (whether manual backend enablement, account review, or system fix) Expected timeline for resolution: Improved support responsiveness - Developers deserve answers, not silence Additional Context: I am ready to provide screen recordings of the exact error I have all the necessary documentation (identity verification, address proof, etc.) I am willing to complete any additional verification steps I simply need clear communication and a path forward I have been developing for iOS and want to contribute to the Apple ecosystem. However, this enrollment barrier is preventing me from doing so. Apple's support infrastructure for India needs improvement, and this issue needs attention. If any Apple team member is monitoring this forum, please escalate this issue. Indian developers deserve better support and communication.

AppIntents don't show up in Shortcuts app when in SPM package
Hi there, I successfully created an AppIntent for our app, and when I had it in the same target as our main app it showed up fine in the shortcuts app. Then I realized that many of the new System Control widgets introduced in iOS 18 (e.g. lockscreen, control center) live in the widget extension target, but they also need to reference that same AppIntent. So to fix this, I thought I'd migrate out the code into it's own SPM package that both the WidgetExtension and the Main App processes can reference. However, after doing that and rebuilding, the intent no longer shows up in the Shortcuts app. Furthermore, my AppShortcutsProvider class now has this error when trying to define the list of appShortcuts: App Intent <name> should be in the same target as AppShortcutsProvider Is this intended, and if so, how do we reference the same AppIntent across multiple targets?

Xcode Devices "Download Container" no longer works on latest Xcode 26.0 (24228) (Build 17A324)
After updating my Xcode to the latest, I am unable to download an installed app container from the Xcode Devices screen.

Why are our macOS builds in Xcode Cloud hanging at the “Archive” stage?
Hello, We are experiencing a persistent issue where macOS builds in Xcode Cloud consistently hang at the Archive stage. The build itself completes successfully, but no artifacts appear, and it seems the build gets stuck during artifact upload. These builds remain in this state for several days (currently 3 days and counting) not failing, but never finishing. We opened a support ticket (102756662562), but we have not received any response yet. We rely on Xcode Cloud for our entire CI/CD pipeline, and at the moment our workflow is completely blocked because of this issue. Has anyone encountered something similar or found a workaround? Thank you.

Apple Watch can't always reconnect
Using Xcode to build and deploy the app to my watch, this is what I get: “Waiting to reconnect to Apple Watch. Previous preparation error: Transport error." And then “Connecting to Apple Watch. Xcode will continue when the operation completes.” And these messages continue to switch between each other. Sometimes the watch to connect and the application starts, but more often a scenario occurs with endless reconnection. I'm using: MacOS 14.4.1 (MacBook Pro 2019; 1.4 GHz Quad-Core Intel Core i5), Xcode 15.3, Watch OS 10.2 (Apple Watch SE 1), iOS 17.1.1 (iPhone 15 Pro). Methods I tried: Connecting Macbook, iPhone and Watch to the same WIfi network; Disabling Watch (and IPhone) from the "Devices and Simulators" menu and setting up Watch (and IPhone) from the beginning. Any help?

Apple Developer Program payment completed but membership not activated
Hello everyone, I’m looking for some guidance to see if anyone has experienced a similar issue with the Apple Developer Program membership. About one week ago, I completed the payment for the membership. I received an email with the subject: We’re processing your order Wxxxxxxxxxx That email included the order details and cost, and shortly after that, I also received the CFDI invoice for the payment, so the charge appears to have been completed successfully. However, up to now: I have not received any membership confirmation email The membership does not appear under Subscriptions in my Apple ID It is not active in the Apple Developer app On the Apple Developer website, I still see the usual message as if the membership was not purchased: “Purchase your membership to continue your enrollment. Buy today” I understand Apple mentions that the purchase may take up to 48 hours to process, but it has now been more than a week with no changes. Has anyone else encountered this situation? Is it normal to receive the invoice but not have the membership activated? Would you recommend contacting Apple Developer Support at this point? Thanks in advance for any help or shared experiences.

Extract Subview option missing in Xcode 26
Hi everyone, I recently updated to Xcode 26.0 and noticed that the “Extract Subview” refactoring option seems to be missing. Now, in Xcode 26, the only options I see under Editor -> Refactor -> are: Extract to Selection File Extract to Method Extract to Variable Extract All Occurrences But there’s no Extract Subview as there was before. Was Extract Subview intentionally removed in Xcode 26? Or is it hidden behind a new menu location or renamed?
