We are encountering a build and archive failure in Xcode after updating our development machine to macOS 26.2. Environment: macOS: 26.2 Xcode: 16.2 iOS Deployment Target / Runtime: iOS 18.5 App Type: Production iOS app (App Store distribution) Issue: Before updating macOS, the project built and archived successfully. After the macOS 26.2 update, archiving fails consistently, even though no major changes were made to the project code or configuration. Certificates, provisioning profiles, and signing settings are correctly configured. The issue appears to be related to the macOS/Xcode environment rather than application logic. Steps to Reproduce: Open the existing iOS project in Xcode 16.2. Select the App Store distribution scheme. Attempt to Archive the project. Archive/build fails. Expected Result: Successful archive allowing upload to App Store Connect. Actual Result: Archive fails after macOS 26.2 update. Additional Info: This post is linked to Apple Developer Technical Support Case-ID: 18413014.

As the title says, in apple developer site under (Certificates, Identifiers & Profiles) all my devices are set to inactive, and I cannot enable them back because my twices are glitched I have 2 devices and they are there twice each with the same UDID. So I cannot enable a single one. I’m hit with “A device with number 'UDID number' already exists on this team.” I have an iPad Pro and iPhone 17 Pro Max, I cannot sign any apps to them at all or do anything because my devices are set to inactive, I’ve contacted apple numerous times, and I can’t seem to get any help regarding this issue. I’ve called and emailed, and the developer team has yet to respond to me, if anyone’s had this issue please tell me how you solved it. i also cannot erase any devices myself until my renewal date. ive tried manually adding my devices, and its the same message that my devices already exist on team. Ive signed out of my apple account on my devices, changed pw, turned off developer mode and renabled it numerous times, I really don’t know what to do.

Hi there! I paid for my Apple Developer Program/Account but its still pending. Any tips what to do? Thanks!

Xcode 26.2 cannot delete the Simulator under Other Installed Platforms. After testing, I found that Simulator Architecture Variant of the Universal type cannot be deleted, but the Apple Silicon type can be deleted. Every time I delete it, it reappears after restarting the computer.

Hello Apple Developers and users I am writing this message reguarding some help on some performance codes/settings I can use for my Macbook since I recently downloaded the MacOs Tahoe 26.2 and its been very glitchy and laggy with gaming and just using my mac normally I have tried using a FPS unlocker and downloading Metal 4 the FPS unlocker hasent worked at all I am still stuck on the normal 60 FPS and need some advice/help. Thank you. Kind regards Zachary

Our app is supposed to be removed from sale on May 31st. Subscriptions our app is offering will also be removed on May 1st one month before our app removal. I would like to know if AppStoreServerNotificationV2 EXPIRED event will be sent to a specified endpoint after the removal of these subscriptions. I think each subscription will be canceled automatically from May 1st to May 31st and it will send EXPIRED event to our server, but is it true? Thank you in advance.

Background: During daily usage of iOS devices, devices experience noticeable thermal issues. This heating not only affects user experience, but may also lead to device performance throttling, shortened battery life, and other problems. We need better understanding and monitoring of device thermal states to optimize application performance and user experience. Issues Encountered: Insufficient thermal monitoring capabilities: Unable to obtain real-time accurate temperature data from devices Difficult power consumption analysis: Hard to determine which specific modules or threads cause high power consumption and heating Requested Solutions: Temperature Monitoring API: Provide accessible device temperature reading interfaces Thermal Attribution Analysis Capability: During heating events, we expect to receive more detailed power consumption monitoring data, such as CPU, GPU, network, location services, display, high power consumption thread stacks and other information to help developers identify high energy consumption operations

Hey all, I recently updated to Xcode 26.2 and I'm having the hardest time trying to download the corresponding iOS simulator. I installed Xcode from developer downloads and the app did not come loaded with an iOS simulator. When trying to download from Components in Settings, I only get the following message: Download failed due to a bad URL. (Catalog download for com.apple.MobileAsset.iOSSimulatorRuntime) Domain: com.apple.MobileAssetError.Download Code: 49 User Info: { checkConfiguration = 1; } I also tried downloading via Terminal but also get a download failed message. I am on the latest macOS and have over 600 GB of disk space available. In previous versions, I was able to download the iOS simulator directly from Developer Downloads, but anything after 26 is not there. Any suggestions?

Been trying to get into Developer Prgram since December 2025. And like many others, it seems the biggest tech company on the planet cannot streamline an enrollment program. Unless, it’s by design, to test your nerve? Anyways, I have now ended up paying twice, and still not even a squeak from support. There is no Developer Support phone number in South Africa, and mails go unanswered. How is this possible? $200 out of pocket, and nothing to show. Cannot even find a method for refunds. If there are steps to still follow or docs to submit, why take my money, then ask for more info?? But this black hole of SILENCE…. Now that skype is no longer, what other platform will allow me to call the US Support number from South Africa?

Hi everyone, With the rapid growth of digital banking, payments, and AI-driven financial services, building secure and scalable FinTech apps on iOS has become more complex than ever. From handling sensitive user data to ensuring compliance and seamless performance, iOS developers face multiple technical challenges. Key areas that usually require deep expertise include: Apple Pay and Wallet integrations Secure authentication (Face ID / Touch ID / biometrics) Real-time transaction processing Core ML for financial predictions SwiftUI dashboards for financial analytics Data encryption and regulatory compliance https://www.nimbleappgenie.com At Nimble AppGenie, we’ve worked extensively as a FinTech app development expert, helping startups and enterprises design and build iOS financial applications that are secure, scalable, and user-centric. Our experience shows that the most successful fintech apps are those that balance strong security architecture with intuitive UX and performance optimization. I’m interested to hear from the community: What are the biggest challenges you’ve faced while building fintech apps on iOS? Are there any recent iOS updates or Apple frameworks that significantly improved your fintech workflows? How are you handling compliance and security in production apps? Looking forward to learning from everyone’s experiences and best practices.

I’ve honestly never received service this bad from a company and I don’t say that lightly. This is the worst support experience I’ve ever had. I’m trying to enroll in the Apple Developer Program, but I’m stuck in a loop that has been going on for months: The Apple Developer app repeatedly fails during identity verification and tells me there’s an issue. When I contact support, they tell me they’ll email me instructions. The email says: “Please use the Apple Developer app to enroll.” I reply saying: “I did. It doesn’t work. The verification fails.” And the response is again: “Use the Apple Developer app.” Over and over, with no actual troubleshooting or escalation. This is not a user-error situation — I’m following the instructions exactly. I need someone to look at what’s happening on Apple’s side (verification/enrollment status) and give a real resolution path, not the same copy-paste response. Details: Country/Region: [your region] Devices tried: [iPhone model + iOS version], [Mac model + macOS version] Exact error message shown in the app: [paste here] Support case number (if relevant): 102784352083 What I’m asking: Can Apple reset/clear my enrollment/verification state so I can retry cleanly? Is there an official fix for this verification error? Is there an alternative way to complete enrollment if the app keeps failing? Can this be escalated to the enrollment/identity verification team? Again: I’ve never experienced support this bad from any company. I just want to enroll and pay — but I’m blocked with no real help.

"EnableLiveAssetServerV2-com.apple.MobileAsset.MetalToolchain" = on; ProductName: macOS ProductVersion: 26.0.1 BuildVersion: 25A362 The MetalToolchain is installed, however I keep getting error that MetalToolchain cannot be found by the Xcode "Command CompileMetalFile failed with a nonzero exit code" error: error: cannot execute tool 'metal' due to missing Metal Toolchain; use: xcodebuild -downloadComponent MetalToolchain ❯ xcodebuild -downloadComponent MetalToolchain 2025-10-31 11:18:29.004 xcodebuild[6605:45524] IDEDownloadableMetalToolchainCoordinator: Failed to remount the Metal Toolchain: The file “com.apple.MobileAsset.MetalToolchain-v17.1.324.0.k9JmEp” couldn’t be opened because you don’t have permission to view it.

I’m attempting to install the Metal toolchain in Xcode, but the installation keeps hanging. Through Xcode, it stops at the “Processing” step, and via the terminal, it never goes past “Beginning asset download…”.

We are currently developing a research-based iOS application that relies heavily on background capabilities, specifically Significant Location Change. We are using CLLocationManager.startMonitoringSignificantLocationChanges(). During development, when using Debug → Simulate Location in Xcode, we receive a location update only once. Subsequent simulated location changes do not trigger additional callbacks, which makes testing and development quite cumbersome. Are there any tools, commands, or workflows (e.g., via Xcode, Instruments, or system-level simulation) to reliably simulate multiple significant location change callbacks for testing purposes? If there aren't such tools, how do I test this behaviour reliably, robustly and rigidly?

I have purchased the apple developer account about 2 months ago, my account has not been activated since then. I have reached apple support multiple times over mails, but received no response. We have also shared our D-U-N-S number multiple times over email. Case ID: 102773282429

Hi everyone, I subscribed to the Apple Developer Program on Tuesday evening, Jan 30th, 2025. The payment has already been successfully charged to my bank account, but my account is still showing “Pending” with the message “Subscribe your membership.” It has been several days now, and I haven’t received any confirmation email or any request for additional verification. I’ve already contacted Apple Developer Support via email, but I wanted to check here as well. Has anyone else faced this issue recently? How long did it take for your membership to become active? Any insights or experiences would be greatly appreciated. Thanks in advance!

I've suddenly started seeing hundreds of the same block of four error messages (see attached image) when running my app on my iOS device through Xcode. I've tried Cleaning the Build folder, but I keep seeing these messages in the console but can't find anything about them. Phone is running iOS 26.1. Xcode is at 16.4. Mac is on Sequoia 15.5.

Hi everyone 👋 As a network engineer and indie iOS developer, I couldn’t find a lightweight mobile tool that fully supports IPv4/IPv6 dual-stack diagnostics — so I built NetToolbox -All-In-One Utility for engineers, DevOps, and developers. Here are its core features that solve real mobile networking pain points: One-Click Full Diagnostics: Integrates ping, traceroute, and multi-type DNS queries (A/AAAA/CNAME) — no need to switch between apps IPv4/IPv6 Dual-Stack Support: Seamlessly works in IPv6-only networks, with the ability to test connectivity differences between dual-stack environments LAN Device Scanning: Quickly identifies all devices on the same network segment and checks port availability Offline Functionality: Diagnostic logic is stored locally, enabling LAN troubleshooting without an internet connection Lightweight Design: 5MB install size, no storage bloat, and low power consumption during operation Dark Mode Support: Tailored for developers who work late at night During development, I leveraged Apple Intelligence alongside Claude Code and Gemini 3 to accelerate the process, optimize iOS native networking stack adaptation and local storage logic, and significantly boost development efficiency. I’d love to hear from the community: What must-have features are missing from mobile network diagnostic tools? Do you have experience optimizing iOS workflows with Apple Intelligence? 👉 You can try the app here: https://apps.apple.com/us/app/nettoolbox-all-in-one-utility/id6757392404 Feedback is highly appreciated — I’ll keep iterating to make it better! 🚀
