When working with an Objective-C project in Xcode 26.5, I'm unable to establish outlet and action connections by dragging between XIB files and the corresponding .h header files. This drag-and-drop connection works perfectly after switching to Xcode 26.3.0. In addition, under Xcode 26.5, drag-and-drop linking works normally for projects using Swift files together with XIB files. The issue only occurs with Objective-C .h files and XIB files.

I've never had anything but trouble with xcappdata, but I got what I wanted working in the previous xcode version, I could specify the xcappdata in my testplan and it would work on the simulators. Now, on XCode 27, the xcappdata doesn't load. I look in the xcode 27 release notes and see there is indeed an issue with xcappdata, and a workaround. Workaround: To make a .xcappdata bundle for use in Xcode’s Run scheme action do the following. Add .xcappdata to the folder created by Device Hub when downloading app data containers. Inside that folder make a new folder named AppData. Move the other content in that folder into AppData. For example, com.example.MyApp/{Documents,Library,tmp} becomes: com.example.MyApp.xcappdata/AppData/{Documents,Library,tmp} This is completely unhelpful. When am I downloading app data containers? What folder is created by Device Hub? Where is it? How does this apply to my testplan? What if I have multiple xcappdata bundles for different test plans? It looks to me like this workaround would be part of a script where at some magic moment I inject my app data into a simulator. Which might not be too bad So if I wanted to build this script it I imagine it looks like create a simulator install the app on the simulator find the folder related to the simulator copy in my xcappdata? Then I can run my tests?

Hello. I have just updated to Xcode 27 to support this version, however... my app is a navigation app with CarPlay support... The I/O > External Displays option through the Simulator helps a lot when testing it, but I’ve noticed it is now gone Why? Who thought this was a good idea? Some of us support apps that are beyond a simple ToDo app So now I have to go back to the previous version of Xcode, or what?

How do we get distribution available on Apple HomeView is this iPhone or iPad in Supported Destinations? Thank you.

I’m sharing my experience with an Apple Watch Ultra 2 and Xcode 27.0 in case it helps someone troubleshooting a similar problem. Developer Mode would switch on, restart the Watch, and ask me to confirm “Turn On.” Even after that confirmation, it would revert to off. Xcode detected my iPhone but not the actual Watch, and pairing remained at “Waiting to pair.” The changes that stood out in my case were removing a corporate management/configuration profile that required a complex passcode, changing the Watch to a simple passcode, and putting my Mac, iPhone, and Watch on the same private Wi-Fi network. I also temporarily disabled VPN, restarted both the iPhone and Watch, and enabled Developer Mode again. After these changes, the connection succeeded. I changed several things together, so I can’t identify which change was responsible or claim this is a universal fix. This confirms the connection in my case; installing and running an app on the Watch is still being verified. If your device is managed, consult your organization’s IT team before changing profiles or security settings. This is a report of what happened on my setup, not a recommendation to weaken passcodes or bypass organizational policy.

Heya! I'm preparing my apps for the iPhone Duo, but having a hard time with the Simulator for it. Basically it's very very slow, crashes often (not speaking about my app but the device hub tool freezes or crashes). Restarting it often helps to kinda "cleanup" when it starts feeling like deep mud when using it, but it would not make it smooth just less deep mud feeling. I am running it on an M1, so that would probably be a good reason for it going this slow. However, any tips to make it run better? Things, settings I can toggle on and off?

For simctl shipped with Xcode 27.0 build 27A266a, is there a supported way to deliver launch stdout/stderr directly to an in-memory consumer without first writing raw output to a regular file, then stop the collector within a bounded time without forwarding a signal to, blocking, terminating, restarting, or changing signal policy in the launched application? Please identify the documented interface and supported OS/runtime scope, or explicitly state that this combination is unsupported. Do stdout/stderr path options officially accept a FIFO or other nonpersistent sink, and where is that sink resolved? What open/create/truncate/blocking behavior and reader-before-writer order are guaranteed? Which process owns the output writer after launch returns? Does simctl exit or collector detach close, transfer, or leave that writer alive? At consumer byte/time limit, EOF, reader closure, collector failure, or backpressure, what happens to App writes and signals, including SIGPIPE/EPIPE? Is there a supported independent detach/drain mechanism that avoids App effects and indefinite background collection? Can the supported interface guarantee no raw-output file or replay spool before the consumer, and which documented limits can the consumer enforce without affecting App lifecycle? Please identify the supported interface, applicable tool/runtime versions, and documented lifecycle guarantees, or clarify which requirements are unsupported. This request is limited to the public tool interface contract and contains no application logs, source code, device identifiers, customer data, or diagnostic attachments.

xcstringstool compile (and by extension CompileXCStrings in Xcode/Bazel builds) hangs indefinitely on .xcstrings files where one or more keys have a localizations entry count that is a significant outlier relative to the rest of the file's keys — even when total file size and total entry count are unremarkable. The tool produces no error, warning, exception, or log output; it simply spins at high CPU with flat memory until killed.

I am working on adding an iOS app to my existing MacOS app. However Transporter shows them both identically. They have the same icon and the same major version number. Please add some clue as to the OS type of each delivered submission so I can tell them apart.

The iOS 17 simulator does not respond at all when I try to interact with it. The simulator is not frozen as I can still control appearance and launch apps via the right sidebar. Things like the home button and clicking on the screen simply don’t work. I am using Xcode 27 beta 6. Feedback ID: FB24674634

Hey all, the codex sign in isn't working for me in Agents. I am using the 26.5 release candidate version. It always says "Not Signed In". I have completed the Sign In process multiple times. Anyone else seeing this? I have filed Feedback FB22732574

In an app using SwiftUI's NavigationSplitView with UIKit view controllers hosted via UIViewControllerRepresentable in the detail pane, a UIBarButtonItem (system .search) in the hosted view controller's navigationItem disappears visually when the iPhone Duo simulator view is dragged to the right side while the Duo is open, while its tap target remains active in the same location, however when tapped, nothing happens. Dragging back to the center restores the icon. The same button, and the same NavigationSplitView layout, is completely stable under equivalent live window-resizing on Mac Catalyst -- resizing the Catalyst window never reproduces the issue. This seemingly points to the Duo simulator's window/hit-test recomposition during the fold transition rather than an app-level bug. See screenshots. I

if i try to take a screen shot of the iPhone duo simulator with the screen shot button at the bottom of the device hub, it turns out all black. This only happens in the folded state.

Installed from the Mac App Store Signed in with my Apple ID in Xcode Apple Intelligence is enabled Chat providers work normally (ChatGPT, Claude, Google) What I expected According to Apple's documentation, the Intelligence settings should display built-in Agents such as: Claude Agent Codex with a Get button to install them. Reference: https://developer.apple.com/documentation/xcode/setting-up-coding-intelligence What actually happens After upgrading to Xcode 26.6, the Agents section only contains: Allow external agents to use Xcode tools Add an Agent... The built-in Agents (Claude Agent and Codex) are completely missing.

Hi everyone, I’m currently running macOS 27.0 beta (26A5388g) on my Mac, along with the latest Xcode 27 beta, and I’ve recently started experiencing a serious issue where multiple macOS system services are repeatedly crashing. Initially, I started getting repeated “intelligencetasksd quit unexpectedly” notifications. At first it happened occasionally, but it has now become extremely frequent. After dismissing one crash notification, another system service often crashes shortly afterward. I’ve also seen services related to Intelligence / intents crashing. The notifications keep appearing one after another to the point where I’m barely able to use the Mac normally — including difficulty typing and interacting with applications. The issue is not limited to Xcode. It appears to affect macOS system services themselves. System information Mac: Mac15,2 (Apple silicon) macOS: macOS 27.0 beta, build 26A5388g Xcode: Xcode 27 beta Issue started: After running the macOS beta for some time; it has progressively become more frequent Main process initially crashing: intelligencetasksd Path shown in crash report: IntelligenceTasksEngine.framework/Support/intelligencetasksd Exception: EXC_BREAKPOINT (SIGTRAP) I have attached a screenshot of the crash report showing the intelligencetasksd crash. Has anyone else experienced this on macOS 27 beta? Is there a known issue with the new Intelligence/Intents services, or is there a recommended way to reset/rebuild the relevant system components? At this point the repeated crashes are making the Mac extremely difficult to use, so I’d really appreciate any troubleshooting steps or information about whether this is a known beta issue. Thanks!

When I try to download the metal toolchain 26.6 (17F109) in Xcode it just stays on preparing to download. Does anyone have an idea on how to fix this? I'm on macOS 26.6.1 (25G76)

I have a problem downloading Xcode components like Metal Toolchain or Developer Documentation. The action stuck with the status "Preparing to download". The symptoms started several weeks ago. I noticed this when my copy of Xcode 27 beta stopped showing the developer documentation. Strangely, when I re-launched Xcode it insists to download the Developer Documentation and keep showing "Preparing to download" while other components like Metal Toolchain, when I quit Xcode, it cancels the component download and that component status reverts to "Get". The symptoms continue thru the released version of Xcode27. Does anyone know the cure?

When I archive and distribute any iOS app from Xcode 27.0 RC on macOS 27.0 Golden Gate, the upload stalls indefinitely at “Preparing to upload [App].ipa”. The archive, signing, provisioning, IPA packaging, and App Store Connect authentication all complete successfully. This is reproducible with multiple unrelated iOS projects on the same machine, so it does not appear to be caused by a specific app, signing configuration, asset, or bundle identifier. Cancelling the upload is the only way to exit the stalled state. I also checked with ChatGPT Codex if it can narrow down the issue. It states: "The failure occurs when Xcode launches the swinfo utility from the ContentDelivery framework to generate the asset description.swinfo crashes with SIGSEGV / exit code 139. The crash report reports:Thread stack size exceeded due to excessive recursion". But I actually never got an error message during the upload itself, it just hangs indefinitely at "preparing to upload..." (Tried it several times up to 36h). This issue is new since I updated to macOS Golden Gate and xCode 27 RC. Xcode Cloud is the only working option right now to upload a Build to App Store Connect. Anyone experiencing the same issue and found a solution? What I already tried: Revoke and renewed my Apple Distribution certificate. Delete xCode, Installed it again (I also installed xCode 27.2 Beta which I knew would not work to upload an app to App Store Connect from a Beta version). Created a brand new project and tried to upload this. Also hang at "preparing to upload..."

Neither in Xcode 27 beta 1 or 2 we have been able to use simulators for the intel x86 architecture. Is there any way to get them?

This is a repost of https://discussions.apple.com/thread/253025487 Hi, How do you pipe selected text in Apple Xcode out to an external program, replacing it with the output from that program? For example, in MacVim, you can type !}command to pipe the rest of the current paragraph to command, replacing the original text with the output of that command, which is hella useful if you’ve written a lot of filters for tasks like automatic text reflowing or automatic source code reformatting. How do you do this in Apple Xcode? I am running Apple Xcode Version 10.1 (10B61) [the highest-numbered, most-recent version of Xcode compatible with Apple macOS Version 10.13.6 “High Sierra”]. ’preciate it, Austin
