In Xcode's Settings → Intelligence section, there's no built-in AI agent/model available, only chat bots. I'm not able to download a model through the Components section as well, but no models are offered or downloadable there either. Environment: Xcode 26.6 and Xcode 27 beta 6 macOS 26.6.2 MacBook Pro (Apple M4 Pro)

After building our app with Xcode 27.0 (27A266a), we observed that it crashes immediately at launch on devices running iOS versions below 17. Devices running iOS 17 or later appear unaffected by this issue. The previous release, built with Xcode 26, worked on older iOS devices. Deleting and reinstalling the affected app does not resolve the crash. Build settings: Minimum deployment target: iOS 15.0 Swift language mode: Swift 5 Configuration: Release Two crash reports from iOS 16.3.1, covering separate app builds produced with Xcode 27, show the same error: Exception Type: EXC_CRASH (SIGABRT) Termination Reason: Namespace DYLD, Code 4, Symbol missing Symbol not found: _$ss12_ArrayBufferV19_getElementSlowPathyyXlSiFyXl_Ts5 Referenced from: Topi.app/Topi Expected in: /usr/lib/swift/libswiftCore.dylib (terminated at launch; ignore backtrace) The symbol demangles to: generic pre-specialization <Swift.AnyObject> of Swift._ArrayBuffer._getElementSlowPath(Swift.Int) -> Swift.AnyObject The system launch screen appears, then dyld terminates the process before application startup code executes. We have not yet isolated whether the reference comes from compiler-generated application code or a linked dependency, nor completed a same-source comparison between Xcode 26 and 27. Is this a known Swift runtime compatibility issue with Xcode 27 when targeting iOS below 17? Is there a supported fix or workaround that preserves iOS 15 and 16 support?

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

The new changes to Xcode for adding a project are ridiculously frustrating. I know exactly what directory I want to put my project in, and exactly what kind of project I need. Why in the world is the new user interface so primitive and incapable of allowing experienced developers to add a new project?

In process of creating an iOS app and installed Xcode 27, now when I add a simulator in the Device Hub the iOS version needs to be 27 or I get an incompatible version error. Also when I select the top app icon the tabs such as the build settings is not showing, only the non-modifiable text file. I'm sure the fix for both is simple but I need pointed in the right direction.

Where's the whole I/O menu? I need the External Display simulator to test my app, and for my surprise, Device Hub lack this whole menubar!

Hello everyone, I am experiencing a severe, workflow-breaking issue with the new Device Hub implementation in the latest stable release of Xcode 27 running on macOS 27. My development machine is an M1 MacBook Pro with 8GB RAM and a 512GB SSD.The simulator has become completely unusable, forcing a massive degradation in my development workflow. The Problem:100% CPU Consumption: When launching a simulator (iOS 27.0), the system instantly spikes to maximum processor usage. While DeviceHub.app spawns the window, the background processes diskimagesiod and CoreDeviceService relentlessly consume between 50% to 95% CPU each, even when the simulator is completely idle.Total Input Lockout / Broken Shortcuts: Absolutely no keyboard shortcuts pass through to the simulator window (e.g., standard development hooks or navigation). The simulator completely stops responding to touch inputs or hardware button clicks, getting stuck in a rigid runtime loop.Immediate Relief Upon Killing Process: The moment I manually force-terminate devicehub via Activity Monitor or Terminal, my overall system load instantly drops back down to a peaceful 2.48% CPU with ~94% idle.Underlying Error Logs:When launching the binary directly from the terminal via /Applications/Xcode.app/Contents/Applications/DeviceHub.app/Contents/MacOS/DeviceHub --booted, the console outputs a massive stream of critical class duplication conflicts between the native OS and private developer frameworks objc[4489]: Class ..._TTC12UniversalHID26TouchSensitiveButtonFilter is implemented in both /System/Library/PrivateFrameworks/UniversalHID.framework/Versions/A/UniversalHID (0x2ec5a4c8d) and /Library/Developer/PrivateFrameworks/CoreDevice.framework/Versions/A/Frameworks/UniversalHID.framework/Versions/A/UniversalHID (0x105025580). One of the duplicates must be removed or renamed. objc[4489]: Class ..._TTC12UniversalHID15DigitizerFilter is implemented in both /System/Library/PrivateFrameworks/UniversalHID.framework/Versions/A/UniversalHID and /Library/Developer/PrivateFrameworks/CoreDevice.framework/... One of the duplicates must be removed or renamed. Impact:Because these private frameworks are deadlocking over registering duplicate input pointers for touch coordinates, scrolling handlers, and button filters, the core virtualization engine hangs.Wiping DerivedData, clearing out iOS DeviceSupport caches, and running xcrun simctl erase all do not resolve the issue. Because the standalone legacy Simulator.app has been entirely removed from /Contents/Developer/Applications/, there is currently no way to bypass this bugged DeviceHub implementation natively.On an 8GB M1 machine, this bug completely thermal-throttles the hardware and paralyzes the local testing pipeline. Is anyone else hitting this linkage deadlock on version 27, or is there a known hidden defaults write flag to decouple input filtering from the CoreDevice workspace loop? Any assistance or temporary patches from the engineering team would be highly appreciated.

I recently upgraded my OS and when opening XCode I cannot find the Object Palette. Has it been removed or is there a shortcut to show it? I have looked on YouTube for a tutorial but cannot find this in relation to this. Thanks in advance.

Environment: Xcode 27.0 (27A266a), Mac App Store macOS 27.2 beta 1 (26B5086k) MacBook Pro M3 Max, 48 GB (Mac15,9) Xcode crashes 100% of the time the moment I start typing a new variable inside a struct in the source editor. Building, running and debugging all work fine — the crash only happens on keystroke in the editor. Crash log points to CoreML predictive code completion: EXC_BAD_ACCESS (SIGBUS) on thread MLSymbolPopularity.workQueue -> Espresso::inner_product_kernel_cpu::get_biases() -> CodeCompletionModel.init -> MLSymbolPopularity.loadModelIfNeeded So the Espresso/CoreML runtime in macOS 27.2 beta 1 crashes while loading the predictive-completion model. Tried, none fixed it: "Display code predictions" -> Never "Display code completions while typing" -> Manually defaults write com.apple.dt.Xcode IDEPredictiveCodeCompletionEnabled -bool NO Cleared DerivedData / Xcode caches Installed the full 2.25 GB model via Settings > Components (still crashes) Not in the beta 1 "Known Issues". Filed: FB24823899 (Core ML, with two .ips crash logs + repro steps). Anyone else seeing MLSymbolPopularity here?

Why doesn't iPhone 13 Pro Max and Watch Series 11 not connect to Xcode 27.0? Something is wrong and I cannot vet the application before submitting for App Store.

With the limitations on not being to install larger hard drives on all Macs these days, the built-in drives tend to fill up very quickly. One of the fastest ways my drive space disappears is the installed platforms in Xcode. Every month or two I have to go in and free up 80GB by removing all the old versions of installed platforms. I would REALLY love a first-party supported way to a) store these installed platforms on an external drive (I could not get a symlink to work properly), or b) a setting to automatically remove older platforms in the same major revision when a newer one is installed. Both my Mac mini and MacBook Pro would love this, especially in the days of SSD scarcity that we are in now.

I can't get simulator to show up in XCODE. I have installed and reinstalled countless times but Simulator is nowhere to be found.

Hi guys In Xcode 27, we have to create the Assets Catalog file ourselves. This file is empty. The icon now is generated by Icon Composer, but how do you specify the accent color? I tried creating a Color set with the name AccentColor but didn't work. And look for options in the project settings but couldn't find any.

Hello. Is there a possibility to disable saving password to account functionality in iOS Simulator ? (It breaks an automation tests) Thanks

Just download 27.1 and Device Hub 27.1 and unable to locate the iPhone Duo simulator. Please help what are the steps to get this? I have both Xcode 27 and Xcode 27.1 installed. 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.

Not able to copy anything from device hub

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

Everything has been updated. Countless reboots and reinstalls. Yet Xcode still won't open. Keep getting "Xcode quit unexpectedly dialog" with buttons to Reopen, Ignore, Report. Any suggestions on what lingering file is killing Xcode on open? Thanks!

We are planning to upgrade our CI setup to run on Xcode 27, but we want to run tests on several older iOS simulator runtimes: 26, 18, 17… With Xcode 26.6, we had no trouble installing the needed runtimes by running: $ xcodebuild -downloadPlatform iOS -buildVersion 18.6 $ xcodebuild -downloadPlatform iOS -buildVersion 17.5 $ xcodebuild -downloadPlatform iOS -buildVersion 16.4 When using Xcode 27.0 (27A266a), however, the command fails to work for any runtime older than iOS 26.0: $ xcodebuild -downloadPlatform iOS -buildVersion 18.6 Finding content... iOS 18.6 is not available for download. At the same time, the runtimes can be installed just fine by using the "Add Platforms…" dialog from the Components pane in Xcode settings. Unfortunately, that's not an option in a headless CI machine. The same issue also reproduces in the beta versions 27.1 (27A9269) and 27.2 (27B5019j), and regardless of macOS version (26.7 or 27.0). Any idea how to work around the issue? I wonder if's a broken backend configuration or a regression in Xcode 27? Posted as FB24836279.
