A Mac reboot fixed it for a few images, but then it went black again.

Instead of centering the content within the available cell space, the content is to the left of center in an iPhone Duo simulation. The content is fine in an iPhone Pro simulation.

Hello, I am playing around with MailKit in Xcode... just created a new App with MailExtension target. When I run it, it's asking if I want to test it with Mail, however, I cannot see the extension in the Mail Settings for enabling it... I a totally newbie here.... what am I missing?

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.

Hello, I’m looking for clarification and guidance regarding a recent App Store Connect upload validation change that is preventing us from delivering an important bug-fix update to existing users on legacy iOS versions. Our production iOS app has historically supported iOS 11 and later. On August 28, 2026, we successfully uploaded a build with: MinimumOSVersion = 11.0 The upload completed successfully, with warnings only. One of the warnings stated: “MinimumOSVersion too low. This app has a MinimumOSVersion of 11.0. Starting later this year, all iOS apps must have a MinimumOSVersion of 13.0 or later in order to be uploaded to App Store Connect or submitted for distribution.” No specific enforcement date was provided. The same upload also displayed another warning stating: “Starting in Spring 2027, all iOS apps must have a MinimumOSVersion of 15.0 or later…” We subsequently uploaded another build targeting iOS 11 around September 8, and that version was successfully released on the App Store on September 10, 2026. I no longer have a screenshot of the warning from that particular upload, but the build itself was accepted and the corresponding version was released successfully. However, on September 17, 2026, when attempting to upload our next bug-fix build with the same MinimumOSVersion of 11.0, Apple’s server-side validation rejected the build with: Error 90068 “This bundle is invalid. The value provided for the key MinimumOSVersion '11.0' is not acceptable.” This means that the server-side enforcement appears to have changed sometime after our successful upload around September 8 and before September 17. What is especially confusing is that: the previous warning only said that iOS 13 would become mandatory “later this year”, without providing a specific enforcement date; iOS 11 builds were still being accepted in early September, including the build that was released on September 10; the same validation dialog stated that iOS 15 would become mandatory only in Spring 2027; the upload now fails completely before the build reaches App Store Connect or TestFlight. Because validation fails during upload, we cannot submit this build to App Review or request an expedited review. We have already completed a final bug-fix release for our existing legacy iOS users. Our intention is not to continue supporting iOS 11 indefinitely. We plan to increase the minimum supported iOS version after this release. We are only trying to deliver one final bug-fix update to users who already have the application installed on legacy iOS versions. The fix is ready, but affected production users currently have no way to receive it. I opened Apple Developer Support Case ID 102966589079 on September 17, 2026 and sent a follow-up on September 21. So far I have only received automated acknowledgements. The Developer Support case history also shows: “Email with Apple Developer Support — September 19, 2026” but I did not receive any email from Apple on that date. I checked Inbox, Spam/Junk, and Trash. Phone support for this case currently shows: “Phone support is currently unavailable due to high call volumes.” I have attached screenshots showing: the successful August 28 upload with the iOS 13 / iOS 15 warnings; the current Error 90068 rejection; the support case history. Could Apple please clarify: On what exact date did the MinimumOSVersion 13 requirement begin being enforced? Was this enforcement date announced anywhere before it became a hard upload requirement? Is there any supported way to upload one final bug-fix build for existing legacy iOS users? Could Case ID 102966589079 please be routed to the appropriate App Store Connect / Distribution team? Thank you.

Each time I launch a Debug version of the app on iOS Simulator, I see the Launch Screen presented and then about a 30-second delay before the app is responsive and debug output appears in the console panel. Filed FB22345091

Hi Team, My Mac has already been upgraded to macOS 27 and currently has Xcode 27 installed. However, I have a development requirement to use Xcode 26.5 as well. Is there any supported way or workaround to install and run Xcode 26.5 on macOS 27? If it is not supported directly, what would be the recommended approach to use Xcode 26.5? Thanks, Reshma

I have been developing an iOS app I have been wanting to release. In the past, I have been able to use my apple account to put things to various testing builds. I did not realize my account had expired earlier this year and I had a build I wanted to work. When I renewed my account, it said it would take a week to activate. It is now over that week period and I cannot use my developer account properly still. Xcode says I do not have a valid method to upload my new build and all my old builds for some reason cannot be used. My account has a red 'x' next to it when I try to manage it on my macbook. Does anyone have any advice on how to help as I have 2 have emails to apple support over the past week that have just been ignored.

It looks like the other thread got locked. I would still like to be able to uncheck the box for "Connect via network" so I can develop with my iOS 17+ devices normally with Xcode 15. Or a method to use Xcode 14 with iOS 17+ without CoreDevice or whatever the problematic API is.

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... ?

Hello, I’m trying to pair an Apple Watch Ultra 4 running watchOS 27 with Xcode 27, but the watch does not appear in Device Hub or under “Pair Nearby Device”. The iPhone paired with the watch is detected correctly by Xcode. Developer Mode is enabled on both devices, and the Mac, iPhone, and Apple Watch are on the same Wi-Fi network. I have already tried restarting all devices, connecting the iPhone by USB, disabling and re-enabling Bluetooth and Wi-Fi, disabling VPN/firewall software, and checking that the watchOS Developer Disk Image is installed and usable. The watch still does not appear as a physical device. Only Apple Watch simulators are listed. Has anyone experienced this issue or found a workaround? Thank you.

Hi everyone, I downloaded Xcode 27.0 today because I need the Metal Toolchain for Unreal Engine 5.6 on my Mac. Xcode itself is installed and working, but Unreal is having issues because the Metal Toolchain doesn't seem to be installed. When I run: xcrun metal --version I get: error: error: cannot execute tool 'metal' due to missing Metal Toolchain; use: xcodebuild -downloadComponent MetalToolchain I tried: sudo xcodebuild -downloadComponent MetalToolchain but it just stays on: Beginning asset download... If I cancel it, I get: xcodebuild: error: Download was cancelled. (Asset download for com.apple.MobileAsset.MetalToolchain ...) I've also run: xcodebuild -runFirstLaunch and installed the latest Command Line Tools for Xcode 27.0 through Software Update. xcrun --find metal does find the executable, but the actual Metal Toolchain appears to be missing. I'm mainly trying to get this working so I can use Unreal Engine 5.6. Has anyone had this issue with Xcode 27, or know the correct way to install the Metal Toolchain when xcodebuild -downloadComponent gets stuck at "Beginning asset download"? Thanks!

If .topBarPinnedTrailing is used for the placement of a ToolbarItem, if this item is the only one in the toolbar then it is not displayed. This .topBarPinnedTrailing appeared in iOS 27.0 to allow a button to be always visible in the toolbar if when there are overflows with many buttons in the toolbar. A toolbar button should always be visible, this behaviour is a bug. It is a great issue on iPhone Duo which has less space for buttons in the toolbars, this attribute was designed to be sure the button using this attribute would always be visible. Bug is also there on Mac Catalyst and visionOS. A feedback was created FB24882292 /// Shows a View with a toolbar with a .topBarPinnedTrailing button. /// If the tool is the only one, it is not displayed. It is designed to be always visible, but it can be missing on the screen. /// If there are one or more additional buttons, then the .topBarPinnedTrailing is well displayed. /// /// Bug reproduced on iPhone 18 Pro Max simulator 27.0, iPhone Duo simulator iOS 27.1, /// Mac Catalyst 27.0, Vision Pro simulator visionOS 27.0 /// > Warning : to test this ContentView, embed it in a NavigationStack. struct ContentView: View { @State private var twoButtons = false var body: some View { VStack { Text("A toolbar should be always visible") .padding() Button { twoButtons.toggle() } label: { Text(twoButtons ?

Xcode 16 and 26 changes in painful way how the Tab key works during autocomplete. Previously, pressing Tab would extend the typed text up to the word match. For example, we have two classes: NSViewController and NSViewCoordinator BEFORE, typing: "NSV" + Tab used to complete to NSViewCo Now, in Xcode 26, pressing Tab just use the first suggestion. Stupidly. Especially when you want DispatchQueue and it gaves you DispatchSemaphore… That is very inconvenient because very often I want just see all possible cases with some prefix...without need of typing all prefix manually. How to restore the previous behavior? How to do autocomplete word-by-word?

Hi All, We build a new feature according to the Apple docs: In iOS 17 and later, App Clips can use the Wallet capability. For more information on functionality that’s available to App Clips, see Choosing the right functionality for your App Clip. and based on that we proceeded with our development, our but in our appclip we are not able to see the wallet capability in the developer portal but for our main application the wallet is there and we enabled it and therefore the com.apple.developer.pass-type-identifiers entitlement has been added to our main app and the appclip, the signing for the main app is working fine, but for the appclip we are getting this issue: Entitlement com.apple.developer.pass-type-identifiers not found and could not be included in profile. This likely is not a valid entitlement and should be removed from your entitlements file.

Hi, I have two points regarding the search function. In other applications I use, it’s possible to highlight a word and then press CMD-F to have that word automatically populated into the search field. This doesn't work in Xcode, and it’s really annoying. Secondly, it bothers me that the two search fields—the one in the sidebar and the one above the editor window—are linked; specifically, when I clear one, the other disappears as well. They serve two different purposes and should remain separate. Christian

Every time I edit anything in the editor Xcode crashes. I did some research and found that if I disable code completion I dont get this issue but code completion is a huge time saver so I dont want to lose that. I have tried clearing my build folder, deleting derived data switching from Xcode 27.2 to 27 and 27.1 but I keep getting the same issue. This is a known issue in 27.2 (186939138) but it isn't listed anywhere else, am I the only person getting this bug? Anything else I should try? This just started happening today, my Mac updated to 27.2 last night. Mac OS 27.2, M4 Pro

Launched 27.1 does not have Duo sim and all test devices in providing incompatible... What are the exact steps for testing an existing app with compatibility with 27.1 iPhone Duo? Thank you.

Hello, Does anybody know how long Xcode takes preparing before starting downloading? Is one hour enough?
