Some Macs recently received a macOS system update which disabled the simulator runtimes used by Xcode 15, including the simulators for iOS, tvOS, watchOS, and visionOS. If your Mac received this update, you will receive the following error message and will be unable to use the simulator: The com.apple.CoreSimulator.SimRuntime.iOS-17-2 simulator runtime is not available. Domain: com.apple.CoreSimulator.SimError Code: 401 Failure Reason: runtime profile not found using "System" match policy Recovery Suggestion: Download the com.apple.CoreSimulator.SimRuntime.iOS-17-2 simulator runtime from the Xcode To resume using the simulator, please reboot your Mac. After rebooting, check Xcode Preferences → Platforms to ensure that the simulator runtime you would like to use is still installed. If it is missing, use the Get button to download it again. The Xcode 15.3 Release Notes are also updated with this information.

When attempting to build an Apple Vision Pro application written in Swift in Xcode, we get the following status errors: "Provisioning profile [Profile Name] doesn't include the Main Camera Access capability.” and "Provisioning profile [Profile Name] doesn't include the com.apple.developer.arkit.main-camera-access.allow entitlement.” The provisioning profile we are attempting to use DOES have the Main Camera Access capability enabled through the Apple Developer portal. We have tried deleting and remaking the profile multiple times, as well as creating new profiles with the same settings, but completely different names and bundle identifiers, but keep getting the same errors. We DO have the "com.apple.developer.arkit.main-camera-access.allow” added to the entitlements file of the Xcode project, and we DO have the “NSMainCameraUsageDescription” key added to the info.plist file, along with the needed string describing the camera usage. Our organization has a valid and active Enterprise account, through which we have requested and been granted access to the “Main Camera Access” capability. We have built this applications multiple times before in the past year with no issues, these errors began after one of our provisioning profiles expired and we re-made it. We have tried clearing the Provisioning Profile Cache on our machine, clearing the Derived Data in the Xcode settings, and clearing the Xcode build cache. We are experiencing these errors on multiple machines, with different versions of our app, and with completely different apps that use the Main Camera Access entitlement. We experience these errors when the profile is downloaded directly in Xcode, and when it is downloaded from a browser and imported into Xcode. When we use “Automatically manage signing” our app properly builds and deploys to the Vision Pro, but when we use the app and attempt to access the main camera, the app crashes with the exception: "Exception: This app failed to request an authorization.” We have searched online forums and found several instances of others that have experienced this problem, but have not found a solution that works. Software Versions: Xcode Version: 26.6 macOS Version: Tahoe 26.5.1 VisionOS Version: 26.5

For the life of me, I cannot find how to bring up the Siri Remote in the Apple TV Simulator in Xcode 27 Device Hub (Beta). Is it no longer available? I have always seem to have had issues using the computer's keyboard for navigating my tvOS apps. Maybe it's me, but the Siri Remote always worked perfectly fine. I hope the remote will make a reappearance in the next beta... ?

Xcode 27.0: Apple TV Simulators fail to navigate to some buttons in a UIViewController via keyboard arrows. Works fine with Xcode 26 (Siri Remote) simulator and also works as expected on an actual Siri Remote for Apple TV device running tvOS 27 Beta. Anyone else experience issues with navigating their app's UI using the Mac keyboard in Device Hub? Any tips for tracking this down?

Free Personal Team, hitting "Your development team has reached the maximum number of registered iPhone devices." I need a local build on a physical device for a demo, so I'm looking for the fastest supported path rather than a fix for the underlying behavior. Context: I hadn't used this Apple ID for development in about two years, so the usual "wait a week for registrations to expire" advice doesn't seem to apply here. The registrations appear to have persisted well past that window. Already tried: removing and re-adding the account in Xcode, clearing ~/Library/Developer/Xcode/UserData/Provisioning Profiles, deleting the developer profile from the device, and confirming this isn't the separate offloaded-apps issue that causes the "maximum number of apps for free development profiles" error. Free accounts have no Devices page, so there's nothing to clear manually. I'm aware of two options: enroll in the Developer Program, or create a new Apple ID and use it as a fresh Personal Team. I've also seen reports of people calling Apple Support and having devices dropped manually, with mixed results. Is the phone call route still viable for someone on a free account, or has that closed? And is there anything else I'm missing before I go the new-Apple-ID route?

Hi everyone, We're running Xcode/Swift CI builds inside macOS VMs (Tart / Apple Virtualization Framework) on a 32-core Apple Silicon host. While investigating VM build performance, we noticed a consistent pattern: assigning 24 vCPUs to the VM produces faster overall build times than assigning 26-30 vCPUs, despite the host still showing idle CPU capacity. With higher vCPU allocations, the build starts by utilizing the CPUs well, but later stages show a noticeable drop in CPU utilization and overall build throughput. In contrast, the 24-vCPU configuration maintains more stable CPU usage and completes the workload faster. This was observed repeatedly with the same Xcode/Swift workload. The result seems counterintuitive because the VM is not exhausting the available host CPU resources. Our testing identified 24 vCPUs as the current sweet spot, even though the host provides 32 physical cores. Has anyone observed similar behavior? Some questions I have: Do Xcode builds stop scaling efficiently beyond a certain vCPU count? Are there known scheduler or virtualization effects when assigning nearly all host cores to a macOS VM? Is there a commonly recommended practice to leave a number of host cores unassigned, even when the host appears mostly idle?

In Xcode 27 Beta 4 (27A5228h), building a project that has a SwiftPM binary target (xcframework) linked directly from both an app target AND a framework target that is embedded in that app fails with "Multiple commands produce" errors. The same project and pbxproj builds successfully in Xcode 27 Beta 3 (27A5218g), so this is a regression introduced in Beta 4. Steps to Reproduce Create a new iOS App project. Add a Framework target (e.g. "SampleCommon") and embed it into the app. Add a SwiftPM dependency for a package that vends a binary xcframework product. Confirmed with airbnb/lottie-spm 4.6.1 (https://github.com/airbnb/lottie-spm). In "Frameworks, Libraries, and Embedded Content" of the app target, add the SwiftPM product (Lottie) with "Embed & Sign". In "Frameworks and Libraries" of the framework target, add the same SwiftPM product (Lottie). Build the app scheme for iOS Simulator. Expected result Build succeeds. The xcframework is embedded exactly once into the .app bundle. This is the behavior in Xcode 27 Beta 3 and Xcode 26. Actual result Build fails with: error: Unexpected duplicate tasks error: Multiple commands produce '.../<App>.app/Frameworks/Lottie.framework/Lottie' error: Multiple commands produce '.../<App>.app/Frameworks/Lottie.framework' Two Copy tasks are emitted for the same output path in the app target: Copy from Build/Products/Debug-iphonesimulator/PackageFrameworks/Lottie.framework Copy from SourcePackages/artifacts/lottie-spm/Lottie/Lottie.xcframework/ios-arm64_x86_64-simulator/Lottie.framework Additionally, an auto-generated target named "Lottiedynamic-product" emits duplicate MkDir / ProcessInfoPlistFile tasks for PackageFrameworks/Lottie.framework, which suggests the packaging path for binary xcframework products has been duplicated in Beta 4. Regression Xcode 27 Beta 3 (27A5218g): builds successfully Xcode 27 Beta 4 (27A5228h): fails with the above errors Xcode 26.x: builds successfully Minimal reproduction The issue reproduces on a 2-target Xcode project (app + framework) with airbnb/lottie-spm added and linked from both targetstory captures the smallest triggering diff: pattern1: app links Lottie only -> BUILD SUCCEEDED pattern2: framework links Lottie only -> BUILD SUCCEEDED pattern3: both app and framework link Lottie -> BUILD FAILED (only on Beta 4) Only the framework target's packageProductDependencies and Frameworks build phase entries differ between the succeeding and failing states. Workaround Link the SwiftPM binary product from only one target (either the app or the framework, not both). If only the framework tarl gets the framework transitively at runtime. Impact Any project that uses a SwiftPM binary xcframework and organizes code across multiple linked targets (a very common pattern for larger apps) is blocked from adopting Xcode 27 Beta 4. Environment Xcode 27.0 Beta 4 (27A5228h) macOS 26.5.2 Package: airbnb/lottie-spm 4.6.1 Destination: iOS Simulator (iPhone 17, latest)

Hello, I am trying to use XCode to generate a 'embedded.provisionprofile' file. My Xcode macos project keeps giving me an error saying: Provisioning profile "BRandNewMebedded" doesn't include signing certificate "Apple Distribution: Martin Barker (LV6WXG529F)". When I download the Provisioning Profile file "BRandNewMebedded" from online, I make sure it has "Mac App Distribution" checked, but even if i edit it to use the first option "Distribution" and re-download it, my XCode keeps saying the same error in red.

We need guidance regarding the Python runtime bundled with Apple Command Line Tools. Environment: macOS Tahoe 26.5.2 (25F84) Xcode 26.6 (17F113) Device type: Mac Command Line Tools Python path: /Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.9/ Version confirmed locally with: /Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.9/bin/python3 --version Output: Python 3.9.6 Our vulnerability-management platform, Qualys, reports this Apple Command Line Tools Python runtime as vulnerable under QID 387170, referencing CVE-2022-4303 and CVE-2023-0286. The detection points to: /Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.9/Resources/Python.app My understanding is that this runtime is bundled and managed by Apple as part of Command Line Tools, and that manually replacing or modifying this framework is not a supported remediation path. Installing a separate standalone Python version also does not remediate the finding at this Apple-managed path. Could Apple or the community confirm the supported approach for this scenario? Specifically: Is Python 3.9.6 intentionally bundled with the current Command Line Tools release for this macOS/Xcode version? Has Apple applied security fixes or backports to this bundled Python runtime that are not reflected in the upstream Python version number? Is updating Command Line Tools/Xcode the only supported remediation method for this component? Is manually replacing or modifying the bundled Python framework unsupported? Is there any known mitigation or official guidance for vulnerability-management exceptions while waiting for an Apple-provided update? I have also filed this through Feedback Assistant: FB23893693. Any official Apple guidance or reference to existing documentation would be very helpful, as we need to provide an auditable response to our internal security and audit teams.

I’m seeing a regression in Xcode 26.4 where Interface Builder will not allow connecting IBOutlets or IBActions. Symptoms: The usual gutter circle/dot does not appear next to IBOutlet / IBAction in the code editor Because of this, I cannot: drag from storyboard → code drag from code → storyboard The class is valid and already connected to the storyboard (existing outlets work) Assistant Editor opens the correct view controller file Important: The exact same project, unchanged, works perfectly in Xcode 26.3. I can create and connect outlets/actions normally there. ⸻ Environment Xcode: 26.4 macOS: 26.4 Mac Mini M4 Pro 64G Ram Project: Objective-C UIKit app using Storyboards This is a long-running, ObjC, project (not newly created) ⸻ What I’ve already tried To rule out the usual suspects: Verified View Controller Custom Class is correctly set in Identity Inspector Verified files are in the correct Target Membership Verified outlets are declared correctly in the .h file: @property (weak, nonatomic) IBOutlet UILabel *exampleLabel; Opened correct file manually (not relying on Automatic Assistant) Tried both: storyboard → code drag code → storyboard drag Tried using Connections Inspector Clean Build Folder Deleted entire DerivedData Restarted Xcode Updated macOS to 26.4 Ran: sudo xcodebuild -runFirstLaunch Confirmed required platform components installed Reopened project fresh ⸻ Observations In Xcode 26.4 the outlet “connection circles” are completely missing In Xcode 26.3 they appear immediately for the same code Existing connections still function at runtime — this is purely an Interface Builder issue ⸻ Question The gutter circles appearance has always been flaky in Xcode over the 13+ years I've been using it but now with 26.4 they have completely disappeared. Has anyone else seen this in Xcode 26.4, or found a workaround? At this point it looks like a regression in Interface Builder, but I haven’t found any mention of it yet.

For the last 2 months I have been submitting the first iOS builds of my app “Zema Kirar”. However Appstore connect wrongly rejects it claiming it was built bu a BETA version of xcode and / or MacOS. My Dev Environment I am Running macOS Tahoe 26.6.2, and Xcode 26.6 (Build 17F113). Both are the ”current” latest public (GM) versions required by apple. Steps to reproduce: Xcode cloud build/ and transporter upload completes > I select the build > click save > click on Submit. Appstore connect shows error: Unable to add for Review. The items below are required to start the review process: New apps and app updates must be built with the latest public (GM) versions of Xcode, and the iOS, macOS, watchOS, and tvOS SDK. Apps built with the beta versions aren’t allowed.

Xcode 26.5 stucks on Localization Generating Comments: Running on macOS Tahoe 26.5 When this happens, Xcode does not add new keys, although enabled: The only (known) workaround is to restart Xcode. Same happened with Xcode 26.4, 26.4.1 on macOS 26.4.1.

Is anyone else using one of the "Dark" editor themes (such as "Default (Dark)" or "Classic (Dark)" in Xcode? And is anyone doing this with Xcode 26 on macOS 26? Here's the result while using the "Default (Dark)" theme while my Mac is in "light" mode: Note that the black background of the editor goes all the way to the far left edge of the Xcode window. The large gray area in the project tree is the black background bleeding through the sidebar. This is really distracting. Is there a way to fix this (besides not using a dark theme - I've been using dark themes for over 30 years)? This appears to be a poor design decision in macOS 26 to have split views show the background of the secondary column behind the primary column. iPadOS 26 has the same issue (see https://developer.apple.com/forums/thread/800073).

I’m blocked debugging a watchOS app on a physical Apple Watch. The iPhone connects to Xcode normally (wired), but the Watch either fails to connect with a tunnel timeout or disappears entirely from Xcode after I unpaired it inside Devices & Simulators. Environment Mac: macOS 26.x (Apple Silicon Mac) Xcode: 26.2 iPhone: iOS 26.1 Apple Watch Ultra: watchOS 26.2 (build 23S303) Connection: iPhone connected to Mac via USB (trusted). Watch paired to iPhone and working normally in the Watch app. Issue A (when Watch is visible in Xcode) In Xcode → Window → Devices and Simulators, the Watch shows up but is not usable and fails to connect. Error: “Previous preparation error: A connection to this device could not be established.” “Timed out while attempting to establish tunnel using negotiated network parameters.” In some attempts the Watch shows “Capacity: Unknown” / limited details, and then fails during preparation. Issue B (after unpairing Watch in Xcode only) I unpaired/removed the Watch in Xcode (Devices & Simulators). I did not unpair the Watch from the iPhone. Now: iPhone appears in Xcode and works normally for builds. Watch is still paired to the iPhone and works normally. Watch no longer appears anywhere in Xcode Devices & Simulators (no paired watch section, no watch run destination). What I’ve tried Reboots of Mac, iPhone, Watch (multiple times) Watch unlocked, awake; iPhone unlocked and close to Watch Verified Watch is paired and connected in iPhone Watch app Developer Mode enabled on iPhone and Watch Wi-Fi and Bluetooth ON (Mac/iPhone/Watch), tried toggling both Tried on home Wi-Fi and also with iPhone hotspot (same result) Resetting trust prompts / reconnecting iPhone via USB, re-trusting Mac Apple Watch: “Clear Trusted Computers” Xcode: removing/re-adding devices; clearing derived data; restarting Xcode Watch Developer networking test: Responsiveness = Medium (430 RPM) Questions 1. Is this a known issue/regression with Xcode 26.2 + watchOS 26.2 tunneling (CoreDevice / devicectl)? 2. Is there an Apple-supported way to force Xcode to re-discover a paired Watch after it was removed from Xcode Devices & Simulators (without unpairing the Watch from the iPhone)? 3. Any recommended logs or diagnostic steps I should collect (Console logs, sysdiagnose, specific Xcode/CoreDevice logs) to include in a Feedback report? If helpful, I can provide the full error text from Xcode’s Devices window and any logs you recommend. Thank you in advance,

Installing a development build on a physical iPhone fails with: 0xE8008018 - The identity used to sign the executable is no longer valid. On the same Mac, same iPhone, same codebase and same Xcode, switching to a free personal Apple ID team installs and runs with no error. Only builds signed with our paid organisation team fail. Nothing else changes between the two runs. We have already regenerated certificates and provisioning profiles, deleted the profiles folder, cleared DerivedData, removed old identities from the keychain, trusted the profile on device, and tried both automatic and manual signing. None of it changes the result. We have also gone through the existing threads on this error and none of the suggested fixes apply. The build validates locally but the device rejects the identity. Since the signing team is the only variable between success and failure, what should we be looking at? A support case is open with Developer Support but we have not had a technical response yet.

If you're on an Intel Mac, here's the reason and the fix. Cost me an evening, and I found nothing online except closed bug reports with the same symptom. The problem: The browser flow works fine. You authorize, the page confirms, Xcode acts like nothing happened, no error anywhere. Xcode only downloads the Apple Silicon (arm64) build of its agent binaries. On Intel they can't run at all. The process meant to receive your login dies instantly with "bad CPU type in executable" and Xcode never surfaces it. Check if this is you: file ~/Library/Developer/Xcode/CodingAssistant/Agents/claude/*/claude If it says arm64 and your Mac is Intel, that's the problem. The fix: Open the Info.plist next to the binary. It has the exact download URL. Download the x64 build of the same version. → Claude: change darwin-arm64 to darwin-x64 in that URL. → Codex: grab codex-x86_64-apple-darwin.tar.gz from the matching rust-v release on GitHub. Replace the binary and make it executable: chmod 755 Update the checksum in Info.plist. It's a plain SHA-512: shasum -a 512 Restart Xcode and sign in again. Bonus (Claude Pro / Max) Run claude setup-token in Terminal, then add the token to: ~/Library/Developer/Xcode/CodingAssistant/ClaudeAgentConfig/settings.json {"env": {"CLAUDE_CODE_OAUTH_TOKEN": "your-token"}} Pick "Authenticate with Configuration File" in the agent menu. Runs on your subscription no API key. Heads up: an Xcode update can re-download the wrong binary, so you may have to repeat this until Apple fixes the architecture detection.

I'm unable to use the Claude Agent in Xcode 26 (stable release) running on macOS 27 beta 5. Steps to reproduce: Open Xcode 26 Settings > Intelligence Select Claude Agent Expected: The Account section loads and allows me to sign in / manage my Claude account. Actual: The Account row shows a loading spinner indefinitely and never resolves, so I can't sign in or use the Claude Agent at all. Environment: Xcode 26 (stable), macOS 27 beta 5. Is this a known incompatibility with macOS 27 beta 5? Is there a workaround (e.g. clearing a cache or re-adding the account) to get the Claude Agent account section to load?

I use a free Apple Personal Team with Xcode for on-device testing. My Apple Development certificate created on 15 August 2026 shows “Missing Private Key”, and Xcode is not allowing me to create a fresh replacement certificate. I have already contacted Apple Developer Program Support, and they directed me to the Apple Developer Forums for technical assistance. How can I revoke/reset the unusable certificate or clear the certificate state for my Personal Team so that Xcode can create a new Apple Development certificate?

Hi Apple Developer Community, I’m experiencing a significant delay with my first app submission and wanted to check if anyone else is facing the same issue. I submitted my app Vetline (iOS 1.0) for App Review on August 10, 2026 at 6:55 PM. As of today, August 20, the status is still: Waiting for Review I have not received any communication from App Review or any request for additional information in the Resolution Center. I also contacted Apple Developer Support regarding the delay, but so far I have only received an acknowledgment that my query was received and no further update. Has anyone submitted an app around August 8–12 and experienced a similar delay? If so, how long did it take before your app moved from Waiting for Review to In Review? I’d really appreciate hearing from other developers who are currently experiencing this. Thanks!
