I am unable to use my iPhone 17 Pro as a run destination in Xcode. The device appears at a low level, but CoreDevice / devicectl keeps reporting it as unavailable. Environment • Mac mini (Apple Silicon) • macOS 26.3 (Build 25D125) • iPhone 17 Pro • iOS 26.3 • Xcode 26.3 (Build 17C529) • Xcode 26.4 beta 2 (Build 17E5170d) Symptoms • The iPhone appears in Finder • On the iPhone, I tapped “Trust This Computer” • Developer Mode is enabled • Apple ID is added in Xcode Accounts • Team is configured in Signing & Capabilities • iOS Platform Support is installed • The device still does not become available as a run destination • Devices and Simulators does not show it in a usable state • xcrun devicectl list devices still shows unavailable Output of xcrun devicectl list devices Failed to load provisioning paramter list due to error: Error Domain=com.apple.dt.CoreDeviceError Code=1002 "No provider was found."

However, at the CoreDevice / devicectl layer the device remains unavailable, and Xcode cannot use it for on-device build/run. Is this a known issue with macOS 26.3 / iOS 26.3 / Xcode 26.4 beta 2? Any workaround or additional debugging steps would be appreciated.

Claude Agent OAuth token silently expires and fails to refresh in Xcode 26.4 — requires manual re-auth every 12-24 hours. this was not happening in 26.3, its a regression in 26.4 Details and sysdiagnose submitted: FB22421882

Mac Pro 2019, Tahoe 26.3, Xcode 26.2 Mac Mini 2023 M2, Tahoe 26.3, Xcode 26.2 On Mac Pro 2019 the app is only Intel while on Mac Mini 2023 M2 it is ARM64 only. Both have Standard Architectures (Apple Silicon, Intel). Both have Build Active Architecture Only is set to No (Debug + Release). Happen for default new projet macOS -> App and Obj-C, Xib. No change to defaults setting except uncheck "Automaticaly manage signing" and "Signing Certificate" set to "Sign to Run Locally" HOWEVER On Mac Pro 2019, BigSur 11.7.10, Xcode 14.10 the application is build Universal ! Why cannot build universal with Tahoe 26.3, Xcode 26.2 ? Can I submit a Mac applcation to App Store Connect with BigSur 11.7.10, Xcode 14.10 ? What are the minimal version of Mac Os and Xcode to submit a Mac applcation to App Store Connect ?

Good morning, I assume that coredata model changes are automatically created on the development cloudkit (CD_*) as that has been the behaviour in the past and than you deploy the schema changes to prod. I have a case were a new field in a existing table is not appearing in the dev cloudkit table is there a way to "force" it to show up? thanks in advance

Hello! I'm new to xcode and am developing an iOS app. I hit the following error when build my app: MY_SHA no identity found Command CodeSign failed with a nonzero exit code I have generated my certificate through xcode. I can see the Certificate and the private key in Keychain -> login. But it's not that private key is under the Certificate. They are listed in parallel. The certificate appears in Certificate tab but not in My Certificate Tab. Would that matter? security find-certificate -a -Z | grep -A1 "Apple Development" Gives me the certificate. But security find-identity -v -p codesigning give 0 valid identity found. Could you help me figure out what could be the reason for this? I've been stuck for several days now. Thank you so much!

Since 26.4 beta 3 I've been having errors after a few hours of using Claude Agent. I get an error stating that I am not authed. If I go into Xcode settings, it still shows I am signed into Claude Agent. I have click sign out and then go through the whole auth process again to start using the agent again. This is on two separate computers. Is there anything I can do to stop this behaviour and stay logged in for longer? It worked fine in 26.3.

Hi everyone, yesterday I updated my macOS and Xcode to the latest versions and today I have the strangest thing: Canvas is always crashing whenever I click it, in any and all my Projects. The full Simulator works just fine; only the Preview Canvas crashes. All the crash reports say it's because of AXRemoteElement-BackgroundFetch, and ChatGPT says it's not because of my code. These are very simple Projects, just for experimentation. Nothing complex, just native code while I follow examples in a SwiftUI book. Anyone else having this issue?

Since a combined upgrade to macOS 26.4 and Xcode 26.4 I am plagued by .DS_Store and UserInterfaceState files appearing in my repository list of uncommitted changes. This is preventing commits and merging etc. I have added the following list to both the .gitignore_global file via directly editing the file and also the Xcode>Settings>Git Settings>Ignore Files # Mac OS X .DS_Store # Xcode *.pbxuser *.mode1v3 *.mode2v3 *.perspectivev3 *.xcuserstate UserInterfaceState.xcuserstate project.xcworkspace/ xcuserdata/ # Generated files *.o *.pyc # Build directories DerivedData/ build/ # CocoaPods Pods/ # Carthage Carthage/ # Other *.swp *.lock This has been to no avail. I have raised Feedback FB22370688 for this issue. It has been marked as no similar reports which is odd because there are a lot of mentions of the .DS_Store files appearing in Git and also of problems with the ignore settings of Git. For a while, I successfully prevented the .DS_Store files from showing up as uncommitted changes but now they are back again. I did a git status on the project and got this output for a while Changes not staged for commit: (use "git add <file>..." to update what will be committed) (use "git restore <file>..." to discard changes in working directory) modified: Target Analysis.xcodeproj/project.xcworkspace/xcuserdata/myuserid.xcuserdatad/UserInterfaceState.xcuserstate Ignored files: (use "git add -f <file>..." to include in what will be committed) Target Analysis iOS/ Target Analysis macOS/ Views/Testing/.DS_Store Now, in Xcode it looks like this So the .DS_Store files are no longer being ignored. I have raised an Apple Developer Tech Support (DTS) Question as I have exhausted every avenue that I could find. DTS said to just remove the file(s) in Git. Neither this nor the .gitignore_global file are fixing the problem. This all just seems to be so unnecessarily difficult especially as many others have faced the same problem.

I just submitted a feedback for this (FB9662125) but in the spirit of “share and enjoy”… The cool new Generate Info.plist File feature in Xcode 13 crashes if you try to put an NSLocationTemporaryUsageDescriptionDictionary in your Info.plist file. Here’s a simple repro scenario: Create a minimal iOS app (no Core Data, no tests) Go to target settings → Info tab → Custom iOS Target Properties Click the (+) button on any row to begin inserting a new row Select Privacy - Location Temporary Usage Description Dictionary Click somewhere else or press Return to commit the selection Xcode crashes immediately More generally, it seems that Xcode crashes any time it tries to regenerate your Info.plist file if it contains an NSLocationTemporaryUsageDescriptionDictionary, even if (for example) you manually pasted that dictionary into the file earlier. In that case, merely tapping the (+) button in step 3 above is enough to crash it.

In Interface Builder there use to be a segmented control to switch Inspectors. It's been this way forever. I could switch from: File Inspector Attributes Inspector Size Inspector Etc... Now in Xcode 26.4, it is this clunky pop up button? What? I thought Apple didn't like Interface Builder anymore so I'm surprised they are even touching it. This part of a SwiftUI rewrite or just bad vibes?

After updating to Xcode 26.4 (public release), I’m no longer able to paste from the Mac clipboard into the Simulator. Automatically Sync Pasteboard is on, and I have content on the clipboard, but paste doesn’t work—Cmd+V does nothing, and there’s no Paste option in the context menu. Is anyone else seeing this?

My development work is paused as Xcode is now non-functional on my Macs. Loading any project into Xcode soon leads to a hang and Force Quit. The SDKs are listed as "status unavailable". No Simulators are available. I've tried previous versions of Xcode; removing everything and re-installing; installation from the Store and direct from the Apple Developer site. I've created a Feedback issue. This happens on both of my Mac minis. I'm running Tahoe 26.4 (25E246) on both.

After updating to Xcode 26.4 the pasteboard sharing feature in the simulators doesn't work.

Compile with xcode26 due to the need to maintain compatibility with older third-party libraries and other linker flags -ObjC -ld_classic -Wl,-U,ld64_classic_ordinal_for_proxy -Wl,-no_fixup_chains Will using these settings have any impact

I'm running a macOS 15.2 guest on a macOS 15.1.1 host with UTM. I'm trying to install Xcode from within the App Store but cannot login to the App Store. When I enter credentials and click 'Sign In' I get the Error 'An unknown error occurred'.

Objective C projects, if that matters, but several useful editing features were removed, but the biggest issues relate to Storyboards. Action buttons were moved all around. Not sure why it was changed, as the new layout is not intuitive at all. Loading of storyboards is amazingly slow. It's been getting worse for several revisions, but it is really bad now. Connecting from the storyboard to code is non functional with this revision. Connections have to be done from the code to the storyboard only, which means all the code has to be done before storyboard changes. This is much less efficient for coding. Really dislike 26.4 editing changes. You are making our jobs harder, not easier.

‌Using Xcode 26, the built package encounters device compatibility issues — while it installs successfully on supported iPhone devices, but it crashes immediately upon launch and cannot run normally.‌‌In previous versions of Xcode, the same "minimum deployment" setting in the project did not cause such compatibility issues.‌ The app built with Xcode 26 shows the following behavior when installed and tested on various devices:‌ iPhone6p iOS12.5.8 fails to run 2.iPhone6 iOS11 fails to run 3.Iphone6 iOS12.5.7 fails to run 4.iPhone7 iOS12.1.3 ok 5.iPhoneX iOS 12.2 ok 6.iphone6s plus iOS10.3.1 ok 7.iphoneXS. iOS 12.1.4 ok 8.iPhone11 iOS 13.6.1 ok 9.iPhone7. iOS 13.7 ok We have tested and found that an iPhone 6s Plus running iOS 10.3.1 can normally run the app. We would like to know whether apps built with Xcode 26 are inherently incompatible with iPhone 6 and older devices. Has Xcode 26’s underlying build environment removed full support for the A8 chip, resulting in binary files containing instructions or memory models that older devices cannot parse? ‌Looking forward to your reply‌.

For me it looks like Xcode 26 has problems reading SPM packages from a locally hosted BitBucket git solution. While Xcode 16 work perfectly fine, Xcode 26 fails to load and gives "Server SSH Fingerprint Failed to Verify" as error description. Cleaning build data and DerivedData sometimes makes loading work. Any change in Package dependencies will break it again. Anyone having same problems? How do you handle it?

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,

I just installed Xcode 26.4 RC (17E192) yesterday and found that the documentation window now omits Foundation for me. Searching for "Date" finds the date property from GameKit, Core Data, ... but no Date type. I was previously using 26.4 beta and this was not the case. Is anyone else seeing the same thing?
