I have been struggling with this for a while and have gone through every solution I have found on the forums, so I am hoping someone at Apple or in the community can shed some light on the actual root cause. Setup Mac: macOS 26.7 (Build 25G229) Xcode: 26.2 (Build 17C52) — also tried 16.8 and 26.0, same result Device: iPhone SE (3rd generation), iPhone14,6 — iOS 26.7 (Build 23H24) Developer Mode: enabled on device Pairing state: paired, tunnel connected The error When I connect my iPhone via cable, Xcode initiates pairing and device preparation, then immediately fails with: The developer disk image could not be mounted on this device. Domain: com.apple.dt.CoreDeviceError Code: 12040 Failure Reason: Unable to find a valid DDI for the iOS platform. Run 'devicectl list preferredDDI' from the command line to get more details. User Info: { DVTErrorCreationDateKey = "2026-09-22 17:14:25 +0000"; DeviceIdentifier = "3B75FE83-5833-53B2-8ABE-9AA65A22A1C8"; "com.apple.dt.DVTCoreDevice.operationName" = enablePersonalizedDDI; } Underlying errors: Code 12001 — Unable to find a valid DDI for the iOS platform. Code 12007 — Unable to find a developer disk image to use for the iOS platform (variants: Internal, Public). Diagnosing: no DDIs found for any platform Running the suggested command: xcrun devicectl list preferredDDI Output: Failed to load provisioning parameter list due to error: Error Domain=com.apple.dt.CoreDeviceError Code=1002 "No provider was found." UserInfo={NSLocalizedDescription=No provider was found.} Host CoreDevice version: 518.27 WARNING: No DDI was found for the iOS platform. No DDI was found for the macOS platform. No DDI was found for the tvOS platform. No DDI was found for the watchOS platform. No DDI was found for the visionOS platform. The key signal here is Code=1002 "No provider was found." — this same error appears as a prefix in every devicectl command I run, regardless of the subcommand. I suspect this is the actual root cause, not a secondary issue. Additionally, /Library/Developer/DeveloperDiskImages does not exist on this machine. What I have already tried xcrun devicectl manage ddis update Updating host DDIs at /Library/Developer/DeveloperDiskImages The following directories provided candidate DDIs: /Library/Developer/CoreDevice/CandidateDDIs /Applications/Xcode-26.2.0.app/Contents/Resources/CoreDeviceDDIs After cleaning and updating the installed host DDIs in /Library/Developer/DeveloperDiskImages are equivalent to the original set. The command completes without error, but /Library/Developer/DeveloperDiskImages is still never created. Reinstalling Xcode system resources: sudo installer -target / -pkg $(xcode-select -p)/../Resources/Packages/XcodeSystemResources.pkg No change. Multiple Xcode versions — tested with 16.8 and 26.0 in addition to the current 26.2. Same failure across all. Multiple iOS versions on the device — the iPhone has been factory reset several times and tested on different iOS 26.x builds as Apple released them. Issue persists on all versions. Confirmed xcode-select -p points to the active Xcode installation and xcrun resolves tools correctly. Device info (for reference) xcrun devicectl list devices Name Identifier State Model iPhone de Carlos 3B75FE83-5833-53B2-8ABE-9AA65A22A1C8 connected (no DDI) iPhone SE (3rd generation) The device pairs and tunnels fine. The only blocker is DDI services (ddiServicesAvailable: false). Questions What does Code=1002 "No provider was found." actually mean in the context of devicectl? Is there a provisioning service or entitlement missing on the Mac side? Why does devicectl manage ddis update report success but never create /Library/Developer/DeveloperDiskImages? Is there a prerequisite directory or permission that needs to exist first? Is there a way to manually force-install the DDIs from the Xcode bundle, bypassing the update mechanism? Any guidance would be greatly appreciated. Happy to run additional diagnostics if needed.

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?

Hello, I submitted an Apple Developer Program enrollment as an organization on July 24, 2026. 39 days later, my account still shows "Your enrollment is being processed. Your enrollment ID is M4FJHZY948." Since submitting, I have received no document requests, no verification call, and no emails from Apple beyond the initial confirmation. I have checked spam and junk folders throughout. This is blocking App Store Connect setup for a release we have ready to submit. Could an Apple team member please review this enrollment and let me know whether anything is needed from my side? I can provide documentation or take a verification call at any time. Thank you.

Hello, I am reaching out here because I am experiencing a critical issue with unpaid earnings and cannot get a response through the standard App Store Connect support channels. I recently realized that my account currency was set incorrectly. Because of this issue, several payments were never delivered to my bank: A few hundred dollars from 2024. Over $1,000 from about two months ago. I have repeatedly tried to contact support to get this resolved, even reaching out to other departments out of desperation, but no one has answered me through any medium. To make matters worse, whenever I submit a case to the Finance department, it completely disappears from my "Recent Issues" dashboard. The only cases that remain visible are my App Review threads all of my financial disputes simply vanish after I submit them. Fortunately, I have kept a manual record of the case numbers for every ticket I have opened. Having these funds in limbo with absolutely no communication is incredibly frustrating and unprofessional. Has anyone else experienced finance tickets disappearing from their dashboard? How can I escalate this so an actual representative can look up my case numbers and help release my missing funds? Any guidance would be greatly appreciated.

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)

I enrolled in the Apple Developer Program on September 17, 2026 and received the Order Acknowledgement for the US$99 payment. Apple’s email said the order would be processed within 2 business days, but my enrollment is still showing as pending. I’ve already contacted Apple Developer Support, but I’m curious if anyone else has experienced this recently. How long did your enrollment take to activate? Did it activate automatically, or did Apple Support need to manually review it? Was there any issue with payment, billing information, or identity verification? I’m enrolling as an individual developer from Saudi Arabia. Would appreciate hearing from anyone who has gone through the same situation recently.

Hi, I am trying to sign up for an individual account. As soon as I click enroll now i get error saying contact us. I cannot get in touch with them and when i do get response states 2FA and number should match region. I have completed all of those but still nothing and I have tried with multiple accounts. Please if anyone knows how to help I would really appreciate it.

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?

Dear Apple Developer Support Team, I am writing to urgently escalate my Apple Developer Program enrollment issue regarding Case Number 20000132030420. I have been trying to enroll in the Apple Developer Program for almost two months, but my enrollment is still pending. I have contacted Apple Support multiple times and followed the instructions provided, but unfortunately, I have not received any meaningful update or resolution. More than a month ago, I was asked to submit my government-issued ID for verification, which I submitted as requested. Since then, I have received no update regarding the status of my enrollment. I have also attempted to contact support regarding this case, but my messages have not received a response. This prolonged delay is extremely frustrating and is preventing me from moving forward with my development work and publishing plans. I have been patient and have followed every step requested by Apple, but after nearly two months without a resolution, I am requesting that this case be urgently escalated to the appropriate team and that my enrollment status be reviewed. Please provide me with: An update on the current status of my enrollment. Confirmation that my submitted government ID has been received and reviewed. The reason for the continued delay, if applicable. A clear timeline for when my Apple Developer Program enrollment will be completed. I sincerely hope @Apple @Support can look into this matter and resolve it as soon as possible. This is now my last option to reach out again for support, as I have already spent considerable time trying to resolve this through the existing support channels. I would greatly appreciate a prompt response and resolution to Case #20000132030420. Kind regards,

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.

Enrollment ID: 68PU8B9629 My organization enrollment has been stuck on "Your enrollment is being processed" since 11 August 2026. Apple requested verification documents on the day I submitted; I uploaded them on 13 August and received confirmation of receipt the same day. There has been no decision since - 39 days. I opened support case 102952910936 on 3 September. On 11 September an advisor called me and committed to a reply within 2-3 business days. Nothing arrived. I followed up in writing on 18 September asking for escalation, and there has still been no reply. One detail that may matter: an email dated 10 September appears in my case history that never arrived at either of my registered addresses. I only learned of it from the case log. If the enrollment team's replies are not being delivered to me, that would explain the silence on both sides. Two questions: Is there a way to confirm which address the enrollment team is replying to? Is there an escalation path beyond the callback on the case? Each callback restarts from zero and no advisor has been able to tell me what, if anything, is still missing. I have not re-submitted the enrollment and have not been charged, so there is no duplicate order. I can re-send any document immediately.

I'm gettign webhook error with 403

I created my account and made the payment on September 11th, and it's still pending. The estimated timeframe is 48 hours, and so far nothing. I've already sent two emails to support and haven't received any response either.

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.

My Apple Developer Program membership has expired and my app has been removed. I am unable to find any renewal option or button on both the website and the app. Kindly assist me in renewing my account and reinstating my product at the earliest.

iPhoneSimulator.app used to have the ability to show an external display / CarPlay display, but this feature does not appear to be available in DeviceHub.app, making it difficult (/impossible :( ) to test CarPlay features from the simulator.

Hello, I am looking for assistance from Apple Developer Support regarding my Individual Apple Developer Program enrollment. Case: 102954985235 My enrollment was prevented before I was given an opportunity to complete any additional identity verification or submit government-issued identification. I opened a Developer Support case and requested a manual review. Today I also spoke with Apple Developer Support by phone. During the call I was told that Apple Developer Program membership is not available to everyone and that I am not eligible for membership. However, I was not told why I am considered ineligible, which enrollment requirement I failed to meet, whether there is an issue with my Apple Account, or whether additional verification could resolve the issue. I am an individual developer and I am fully prepared to complete any legitimate identity, address, payment, or account verification Apple requires. Could Apple Developer Support please escalate case 102954985235 to the appropriate Enrollment / Membership team or Senior Advisor for reconsideration and advise what verification or corrective action is available? I am specifically trying to determine whether this is: – an identity verification issue; – an Apple Account eligibility issue; – a regional restriction; – a compliance/security review; – or another enrollment requirement. I am not asking for confidential internal security information. I am asking for an opportunity to resolve any legitimate verification issue affecting my enrollment. Thank you.
