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.

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.

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.

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.

Hi everyone, I'm looking for advice from developers who have dealt with Guideline 4.3 in a situation involving a previously terminated Apple Developer account. We have a legitimate travel booking application that was previously submitted to the App Store under our original Apple Developer account. Unfortunately, that developer account was terminated, and despite multiple appeals/support requests, we were unable to have the account restored. We subsequently created a new Apple Developer account and attempted to submit the same legitimate travel application under the new account. The current application has a significantly redesigned UI and UX, but the mobile application is still based on the original React Native codebase. The backend, APIs, travel integrations, booking system, etc. are our existing platform and are not copied from another application. The submission is now being rejected under Guideline 4.3 with wording indicating that the app shares a similar binary, metadata, and/or concept with apps previously submitted by a terminated Apple Developer Program account. My question is specifically about understanding what Apple may be identifying in this situation. Has anyone experienced a similar case where: The same legitimate product was previously submitted under a terminated developer account. The developer then had to submit it from a new account. The new submission was rejected under 4.3 because of its relationship to the previous app/account. If so, were you able to determine whether Apple's concern was primarily: the binary/source-code similarity, the previous developer account association, metadata/assets, or the fact that it was essentially the same product? I'm considering rebuilding the iOS client from React Native to Flutter as a genuinely new implementation while keeping our existing backend/API platform. Before investing significant development time in that rewrite, I'd like to understand whether changing the mobile technology would actually address this type of 4.3 issue, or whether the previous account association can still cause the rejection regardless of the framework. I'd also appreciate any experience with getting a specific answer from App Review about what triggered the 4.3 rejection in cases involving a terminated account. Thanks in advance.

Anyone know if it is possible to run our app from Xcode 26.3, in an iOS 27 simulator? I see several are listed in the simulator-selection menu but thus far no luck building for them. Background: Trying to see what our app looks like in iOS 27 even before scene delegate migration is complete.

It has been two years since I wrote my a SwiftUI app, and I wanted to start again in Xcode 26. I can no longer see the attributes inspector when I select an element in the canvas. This was an Xcode feature that was very helpful as I am still a novice. Has this feature been deprecated in Xcode 26? And if not, please help explain how I can find and use it.

Good day, I'm trying to resolve the EU "Digital Services Act" compliance for my employer's Apple Developer account, but I'm stuck on verifying the phone number. The email verification code came through without any issue. We are located in South Africa, with a "+27" area code and the number I need to use here is a landline that comes through to the receptionist at our head office. This number does not have the ability to receive text messages, so I selected the "Didn't get a verification code?" link and chose the receive a phone call instead, however the call never comes through. Calling the number from my cellphone goes straight through to the receptionist, there are no digital switchboard prompts for the caller to select from. I tried this numerous times this Friday just past, and again twice now today, still no luck. I've requested an official document from my manager to see if I can go that route to verify the details, but so far nobody seems to be able to find an appropriate document for me to use... :( Is there anything else that I can do here?

Hi. On my iOS app, both the app store and the device are making changes to my app icon to make it look more Liquid-Glass. See attached image showing my original icon, and then how it appears on the app store and on devices. There is an added bevel/3d effect. I'd like to not have this happen. Did anybody figure out how to turn this off? So that the icon appears as submitted. I've played around with Icon Composer a bit but haven't managed to turn this off there. And would prefer to just submit the png's. Thank you!

My Apple Developer account was recently terminated, and I received an email stating that the reason was section 3.2(f) of the Apple Developer Program License Agreement. However, I have not changed anything recently in our apps, business model, or developer activity, and I genuinely do not understand the reason behind this termination. I have always tried to follow Apple’s guidelines carefully and act in good faith. This termination has severely impacted my work and users, and I am urgently requesting clarification regarding what exactly triggered this action. If someone from Apple or the App Review / Developer Relations team could please contact me or review the case again, I would greatly appreciate it. Thank you.

I am using Xcode 26.2, ProductBuildVersion 17C52. I read the xcodebuild(1) manual included with this installation. It describes -checkFirstLaunchStatus as checking whether additional system components or configuration tasks need to be performed, and says that it exits with 0 when system components are up to date. However, it does not explicitly state whether this result includes acceptance of the currently required Xcode and SDK license agreements. Does exit status 0 from: /usr/bin/xcodebuild -checkFirstLaunchStatus also confirm that the required Xcode and SDK license agreements are already accepted? If not, is there a supported, status-only command or user-interface location that reports whether those agreements are currently accepted, without accepting or reaccepting them, installing components, or running a build? Please clarify: The supported command or interface, if one exists. The meaning of its possible status results. Any required privileges. Whether invoking it can change any system or Xcode state. If no supported non-mutating method exists for checking license acceptance separately, please confirm that as well. I have reviewed the locally installed documentation but have not executed the proposed xcodebuild command.

Hi, I'm posting a boot crash here. Environment Hardware: Macbook M5 Pro OS Version: macOS 26.3.1 (25D2128) and matching version of KDK from official apple download page Kernel Version: Darwin Kernel Version 25.3.0 Reproducibility: Consistent Here is my panic log --- I truncated one field "SOCDNandContainer" as the original log is too long to post, hitting the size limit. I followed a blog post to boot the development kernel as the ReadMe file from KDK only contains instructions for Intel Macs. https://jaitechwriteups.blogspot.com/2025/10/boot-custom-macos-kernel-on-macos-apple.html I've tried a few 26.2 KDKs before 26.3.1 public launch, and they all showed same errors (26.1 and 26.0 KDKs don't have any development kernel for T8142 chip). Also, I own two fresh M5 Pro, and it is consistent across the machines. The highlight is panic(cpu 8 caller 0xfffffe0050e18010): [Exclaves] $JgOSLogServerComponent.RedactedLogServer.init(logServerNotific:OSLogServerComponent\/OSLogServerComponent_Swift.swift:815: Fatal error: invalid rawValue for TightbeamComponents.RedactedLogSer at PC ... Is this a genuine bug or am I following a wrong guide to boot the development kernel? I don't think the blog is wrong because I'm able to boot the "release" kernel included in the KDK on the same M5 Pro, and the "development" kernel on M4 Mac Mini, using the same routine. Just to be clear, I'm not compiling XNU myself, but am using the ones included in the kit.

Please help me i waiting for long time can not got email back, what wrong? We are processing your order and will send you and activation email when it's ready. Please note that it may take up to two business days to process your order.

My apps are legacy codebases still using AppDelegate instead of SceneDelegate. According to TN3187: Migrating to the UIKit scene-based life cycle, apps should migrate to the scene-based lifecycle. I have the following questions: Is there a specific timeline or deadline for when this migration will be enforced? Will there be deprecation warnings before the assert is triggered? I've tested my app with Xcode 27 beta, and it's not showing any errors or warnings related to this requirement. Based on this, I'm assuming this scene delegate migration may not be relevant for Apple's yearly requirement to submit new apps with the latest iOS SDK, and won't be enforced in April when "apps uploaded to App Store Connect must be built with Xcode 27 or later using an SDK for iOS 27." Can someone confirm if this understanding is correct?

I want to obtain the precise temperature of the CPU core of the iPhone. What should I do?

I'm going through Company/Organization enrollment in Egypt. D&B's local representative there emailed me on 30 August 2026 requesting a set of documents (questionnaire, registration extract, tax document, ID, declaration letter) — with a deadline of 31 August 2026. That's roughly one business day to gather and prepare everything. On the morning of 31 August 2026 (the deadline day itself, ~06:36 AM UTC — the very morning of the day, the deadline hadn't even ended yet), I received an automated email from D&B's iResearch system saying my case had been "resolved" as "D-U-N-S Number could not be created — Insufficient information provided," noting that an official correspondence had been sent but no reply had been received yet. while we're still in the morning of the only day they gave me as deadline. Later that same day, 31 August 2026 — still within the original deadline — I sent my complete reply to the local representative with all requested documents, including a signed and bank-verified declaration letter. My best guess is that this is two disconnected systems on two different clocks: the automated global case running its own internal timeout logic, separate from the human deadline the local rep set for their own manual process — a coordination gap between systems, not the local rep actually missing anything or breaking their own rule. My question: given the deadline was only ever 31 August, and the automated system closed my case as "no reply" on the morning of that same day (before the day was even over, before the day even started), does this closed status mean anything negative? Is a direct reply to the local representative, sent within the original deadline, enough to move things forward — or does a case auto-closed like this need to be explicitly reopened/relinked? Has anyone dealt with a one-day-turnaround request like this and had it auto-close prematurely? What I want to know: is that read correct? Does an automated "case resolved / insufficient information" status from the global system carry any actual weight if the local representative received my reply within the deadline they set — or is this genuinely just a stale, disconnected status that the local rep can override once they process what I sent? Has anyone seen this exact split between an automated case and a human-set deadline, and can confirm which side actually governs the outcome?

Hello everyone, why should our account with a binary file that is public and all developers can use it be closed according to the 4.3 guideline? But Planet VPN which has more than 11 apps and many other developers can easily use it and there are no problems, be closed? Are these rules only for our company with more than 20+ employees? That our years of effort can end in one day with the decision of an inspector who only checks a system message? Maybe you can check the links: https://apps.apple.com/ae/app/japan-vpn-secure-proxy/id6499425450 https://apps.apple.com/ae/app/vpn-canada-fast-private/id6499426249 https://apps.apple.com/ae/app/vpn-turkey-fast-and-private/id6499426037 https://apps.apple.com/ae/app/vpn-india-private-secure/id6477943653 And you have access to more than 7 other apps and you can see the developer page, blocking an account because of a legal line is not right! According to Apple's fraud or abuse or circumvention rules, this could include account banning, but we can prove with evidence that the reason for marking binary similarity with other developers is simply a public branch that all developers can use on GitHub. Is there really anyone who monitors that the review team does not make dictatorial decisions? If they do not review for more than a month or continue to refuse to accept the developer's application for approval despite explanations and documentation, they have not made a mistake. But if the developers do not change the structure of a public library that is not necessary to build at all due to the similarity of the work, like OpenVPN at its core, they are linking you to other developers who have violated the rules!!! I agree with you, a reviewer whose literacy is at the level of a primary school child. https://github.com/XTLS/Xray-core Many developers may use this core and break the rules. There is no reason why your system should automatically attribute it. You can also impose the same due to the inconvenience and harassment of other developers. You can decide with your own eyes and mind. I wrote this so that maybe a good and responsible person can solve it. Respect to the review team and their senior managers. Regards

Pending Termination Notice Under Section 3.2(f) – Seeking Guidance Regarding Developer Identity Verification Hello, Case ID: 20000132641773 I am seeking guidance regarding a Pending Termination Notice that I recently received under Section 3.2(f) and App Review Guideline 5.6.2 (Developer Identity). I fully respect Apple's policies and have always tried to operate within the App Store guidelines. However, I am struggling to understand the identity-related concerns mentioned in the notice. My Situation I enrolled in the Apple Developer Program as an Individual developer. I completed the standard enrollment process and paid the membership fee. My developer account was approved and activated by Apple. During enrollment, I was not asked to upload a passport, National ID Card, driver's license, or any other identity verification documents. The account has been active for several years. I have multiple published applications and have invested significant resources into their development and growth. My Main Concern The notice states that Apple believes fraudulent or false identity information may have been provided. However: I have never intentionally misrepresented my identity. The name on the account belongs to me. I am fully willing to complete any identity verification process. I can immediately provide my Passport, National ID Card, Driver's License, proof of address, or any other documents Apple may require. Significant Business Impact The termination notice has affected all applications associated with my account. As a result: App transfers are disabled. Earnings payments are paused. Existing applications are impacted. Ongoing user acquisition and marketing campaigns have been disrupted. I have invested heavily in growing these applications, including substantial advertising spend through Meta Ads and other marketing channels. I can provide supporting evidence of advertising activity, installs, traffic, and user acquisition if requested. Questions Has anyone successfully resolved a similar Developer Identity (5.6.2) issue through additional verification? Has Apple allowed developers to submit identity documents after receiving a Pending Termination Notice? Is there any recommended approach when the developer is fully willing to verify their identity but was never previously asked to submit identity documents? I have already submitted an appeal and expressed my willingness to provide any form of identity verification required by Apple. Any guidance from Apple staff or developers who have experienced a similar situation would be greatly appreciated. Thank you.

When I use Xcode 26.6, MacOS Tahoe 26.6.2, for debugging and hit a breakpoint, using "step over" very often causes the debugger to freeze at a random line of code on other threads. Clicking "Pause program execution" indicates that the line is being executed randomly on other threads, but the breakpoint never exits, seemingly causing a freeze. At this point, if I then place a breakpoint just after the point where I was stepping on the thread which I was debugging before the freeze, hitting "Continue Program Execution", ofter - but not always - the debugger returns to the new breakpoint which I placed after the freeze. I am using Xcode on Apple Silicon M4 based Mac, our app is a ObjC application for MacOS and it is native for Apple Silicon. The current situation with Xcode 26.6 significantly reduces our development efficiency. What could be causing this, and is there a solution?
