After updating my Xcode to the latest, I am unable to download an installed app container from the Xcode Devices screen. This currently works with older versions of Xcode with the same app on the same iPad. This worked with older versions of Xcode on the same MacBook as well (including the Xcode 26 beta before updating to the official release yesterday) The specified file could not be transferred.

For difficult reasons I won’t get into, I ended up manually downloading the latest iOS 26 simulator runtime. I now have a file named 78756498-8AB4-4E5A-986C-7AA435758657.aar copied to my Mac. How do I get this archive installed so Xcode 26 recognizes it as a proper simulator runtime component? All searching I‘ve done for manually installing simulators references dmg files and older versions of Xcode. There’s no mention of aar files. When I tried the command: sudo xcrun simctl runtime add ./78756498-8AB4-4E5A-986C-7AA435758657.aar I get the result: An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=22): Error while creating AEA backend Invalid argument I tried to use Archive Utility to open the file but that just says it is unable to expand the file. I even tried renaming the file with a dmg extension and then tried mounting the file and I get the same “AEA backend” error. My Mac doesn’t have sufficient Internet access to let me download and install this normally through Xcode. I need to find a way to get this file installed manually.

I’m building a document-based macOS app using SwiftUI with an AppKit NSDocument. By default, when the window has no toolbar, the document title and proxy icon (with the edited state dot and standard saving controls) appear nicely centered in the title bar. However, as soon as I attach a toolbar - even an empty one - the document proxy moves to the leading edge of the title bar. Is there a way to keep the document proxy/title centered in a document-based SwiftUI app while also using a toolbar? Or is the left-alignment now the only supported behavior when a toolbar is present? Thanks in advance for any guidance.

I have a strange problem. My code works perfectly on my iPhone, i.e. on a real iPhone, but when I upload the build version to TestFlight, it no longer works. I use React Native. The issue is as follows: I have created a code for Grid View that runs automatically when another person joins the stream. It works locally without any problems, but unfortunately the public version does not work. What could be the reason for this?

Upgrading from XCode 16 to 26, I redownloaded the simulators, and now I'm having a blank simulator choice that I cannot seem to do anything about. When pressing the + at the bottom, Xcode stops responding. Things I've tried; Reinstalling Xcode (after removing /devlopers) Changing minimum deployments (to any version) Changing iOS Deployment Target (to any iOS version) Any clues on what I'm missing here? It was working on XCode 16 yesterday. Images https://preview.redd.it/blank-simulators-xcode-26-v0-g7h0rkdt1npf1.png https://preview.redd.it/blank-simulators-xcode-26-v0-zze2zsuv1npf1.png

In a new document-based macOS app project created in Xcode, some of the default system-provided menu commands appear without their standard icons in the menu bar. Steps to Reproduce: 1. In Xcode, create a new macOS “Document App” project (using Swift/SwiftUI or AppKit template). 2. Build and run the project. 3. Open the app’s main menu bar and examine the default items such as New Document, Open…, Save, Duplicate, etc. Expected Results: System-provided menu items (e.g. Open…, Save, Duplicate) should display their standard SF Symbol–based icons automatically, as they do in TextEdit and other system apps. Actual Results: Some of these menu items display only text, with no icon namely: Services Open Recent Revert To Share This happens even though the items are the system-managed defaults generated by the document-based app template. Notes: • No code modifications were made — this occurs in a fresh, unedited template project. • Behavior seen on macOS 26.0 (25A354). • Xcode Version 26.0 (17A324) used.

The other day the XCode account had some error that I so that I decided to log out and in again. But when trying to log in to my apple account I get this "Bad URL" with the description "Try signing in again or contact Apple Developer Support to resolve account access". This only happens on the XCode on my work computer. I can log in to XCode on other computers with the same account. This happens only on this computer and with any account that I try to log in to. Obviously there is some cache file somewhere that I need to delete. But I am not finding it.

I recently updated to macOS sequoia 15.6 Afterward, I updated to Xcode 26 The project I've been running for the last couple years no longer compiles on existing simulators and doesn't build to a physical device. I'm getting an error I'm not familiar with and have no idea how to directly resolve it: The specific error is 'Command SwiftGeneratePch failed with a nonzero exit code' Looking up this issue via Google, there wasn't really a lot of information on this particular build failure. Most suggestions were to change the location of the Derived Data folder (Xcode -> File -> Project Settings -> update location of derived data from default to relative) This was one of the only actionable solutions I found online but this doesn't fully address the issue for me, it just creates a new issue: "Command PhaseScriptExecution failed with a nonzero exit code" I feel like with enough digging around I should be able to find a solution to the "PhaseScriptExecution" issue; there seems to be a decent amount of information online about that particular problem. I would prefer if I could solve the original 'SwiftGeneratePch" failure without needing to address other issues, though. Is this possible?

Hi everyone - I'm seeing an issue specifically on iOS26 where we instantiate a few storyboard items programmatically and pull their restoration identifier. On iOS26, these identifiers are null and cause a crash, but the assignments are on the storyboard and there has been no change to that logic. On iOS 18, for example, there is no crash and the identifiers are pulled properly. Anybody else seeing this?

Hello all, I saw the update of xcode26 on the App store, and from the compatibility information, I saw that xcode26 supports macos15.6 and higher. I'm not sure if xcode26 can be installed on macos 15. I can't install xcode26 on macOS 15.7.

Like I said, Xcode always selects the most recently used device for debugging, but when that device disconnects from the Mac, Xcode takes a long time to load and you can’t dismiss it. What a stupid feature! Has anyone encountered the same issue and found a way to resolve it? Thank you very much!

The iPad Pro on iPadOS 26 now operates on the same class of silicon as Apple’s entry-level Macs. It ships with M-series processors, 8GB of unified memory, support for multiple resizable windows, a menu bar, and proper external display connections. The device already has the foundation required for professional software development. The only gap is the absence of Xcode. Making the full version of Xcode available on iPad Pro would not take away from the Mac. Large and resource-intensive projects will still require the power of MacBook Pro and Mac Studio. What it would do is allow smaller and mid-sized projects to be developed directly on iPad Pro, which the hardware is fully capable of handling. That dynamic is complementary, not cannibalizing. Developers would continue to buy Macs but would also buy iPad Pros for portability and flexibility. The revenue upside is clear. Lowering the entry barrier means more developers enrolling in the Apple Developer Program at $99 per year, creating predictable recurring subscription income. A wider developer base leads to more apps reaching the App Store. Even if many are small, Apple benefits from every transaction through its revenue share. This strengthens the services business, which already delivers the company’s highest margins. There is also a direct hardware impact. Once Xcode is available, iPad Pro will be recognized as a legitimate professional development device. That drives more unit sales of a high-margin product line and increases attachment rates for accessories like the Magic Keyboard, Apple Pencil, and external monitors. Instead of eroding Mac sales, the effect is expansion. Developers will own both devices. The case is straightforward. The hardware is ready. The operating system is ready. Enabling full Xcode on iPad Pro would expand the developer funnel, grow recurring subscription revenue, increase App Store volume, and boost high-margin hardware and accessory sales. It is a decision that benefits developers, strengthens the ecosystem, and maximizes profit.

After updating to Xcode 26 RC on Tahoe 26 RC and iOS 26 RC (and now final version of both Tahoe and iOS). I'm still unable to debug on device. I've tried rebooting, resetting settings, cleaning trusted computers. I ran out of ideas, I was expecting that final versions would fix this but they didn't.

Hello, when building and signing my application in a Github actions workflow, I am facing an issue on the latest version of xCode (16.4). This issue is resolved by downgrading to 16.3. My CI/CD pipeline is running headless and installing provisioning profile to ~/Library/MobileDevice/Provisioning Profiles.

create a sample XCode project using Objective-C and stroybook (xib) using latest XCode beta open MainMenu.xib, and select Main Menu → File → Print... remove the image like below 4. build it 5. run it on macOS 26 beta 7 6. The menu item "print.." still have "Image" Is there any way to remove image for one menu item. I have also tried NSMenuItem.image = nil, but still not work. The issue I met on my own app is that I cannot remove icons for "Zoom In", "Zoom Out" and many other menu items, which makes the menu items not aligned properly.

While preparing automated screenshots with Xcode UI tests for the iOS 26 release, I noticed that this simple line of code app.buttons["myTabItem"].tap() doesn't always work, both on iPhone and iPad Simulator. In fact, it rarely works. Even when repeating the same test, mostly it fails on that line, but a few times it works and I can see the tab item change in the simulator. My main view looks like this: TabView { MyTab1() .tag(tag1) .tabItem { Label("label1", systemImage: "image1") } MyTab2() .tag(tag2) .tabItem { Label("label2", systemImage: "image2") .accessibilityIdentifier("myTabItem") } The error I get is Failed to tap "myTabItem" Button: No matches found for Elements matching predicate '"myTabItem" IN identifiers' from input In the given list of buttons, I see the tab items with their labels, but none of them seem to have an identifier, while other buttons have the correct identifier. I wonder how this can only sometimes work. I tried isolating the issue by iteratively commenting out parts of the SwiftUI code, but unfortunately the behaviour seems erratic. When a change results in the issue not happening anymore, undoing the last X changes often causes the issue to stay away, even with configurations that previously had the issue. I've already spent almost a whole day trying to find the root cause, but with such apparently random behaviour it has proven impossible. Of course, I cannot reproduce the issue with a fresh test project, so the only way to reproduce it with 95% probability is running my original project. Has anyone had the same issue, or does anyone know how I could debug this to find out what causes my UI test to not be able to tap another tab item?

Hi everyone, I’ve run into a strange localization issue with macOS document-based apps in SwiftUI/AppKit. I created a standard document-based macOS app in Xcode (SwiftUI template) and added a French localization to the project. All system-generated menu bar commands (File → New, Close, Print, etc.) are correctly translated into French… except for “Save”, which remains in English. To rule out problems in my own code, I created a fresh, unmodified document-based app project in Xcode, and immediately added French localization without touching any code. Same result: all commands are translated except “Save”. This suggests the issue isn’t specific to my app code, but either the project template, or possibly macOS itself. My environment • Xcode version: 16.4 • macOS version: 15.6.1 Sequoia] • Swift: Swift 6 Questions 1. Has anyone else seen this issue with the “Save” command not being localized? 2. Is this expected behavior (maybe “Save” is handled differently from other menu items)? 3. If it’s a bug in the template or OS, is there a known workaround? Thanks for any insights P.S. Please note that I'm a total beginner

Hi, I am experiencing an issue where Xcode displays a "Provisioning profile doesn't support the capability" error for the User Assigned Device Name capability, despite it being approved by Apple and visible in our provisioning profile on the Developer Portal. Background We have completed and submitted the required capability request form to Apple for the User Assigned Device Name capability and received approval. The capability appears correctly in our provisioning profile on the Apple Developer Portal and shows among the enabled capabilities alongside other standard capabilities like In-App Purchase and Push Notifications. Issue However, Xcode consistently displays the error message when trying to enable the User Assigned Device Name capability in our project settings, preventing successful builds with this functionality. Troubleshooting Steps Attempted We have tried multiple troubleshooting steps including: Regenerating provisioning profiles Performing clean builds Clearing DerivedData Manually installing profiles Adding the com.apple.developer.device-information.user-assigned-device-name entitlement manually to our entitlements file Toggling automatic signing on and off Environment Details Xcode Version: 16.4 (16F6) iOS Deployment Target: iOS 13 Profile Type: Distribution provisioning profile Capability: User Assigned Device Name Despite the capability being approved by Apple and visible in our provisioning profile, Xcode does not recognize it. This appears to be a synchronization issue between the Apple Developer Portal and Xcode's capability validation system. Has anyone encountered similar issues with recently approved capabilities, specifically the User Assigned Device Name capability? Could you please provide guidance on how to resolve this capability recognition issue? Any suggestions for resolving this discrepancy between the Developer Portal and Xcode would be greatly appreciated.
