When I was reading a topic written by somebody, suddenly, the web browser (Safari) directed me to this Unauthorized error page. What the hell is this, Apple, Inc? It seems that things are quite chaotic about what Apple, Inc. does these days. I hope they will manage to sort things out.

Summary: After upgrading to Xcode 26.4, app-hosted XCTest execution on physical devices running iOS 16 fails at test-planning time with "Logic Testing Unavailable." The same project and same device work under Xcode 26.2. The failure reproduces with a standalone minimal Xcode project, which suggests this is an Xcode regression rather than a project-configuration issue. Environment: Xcode: 26.4 (17E192) macOS: Tahoe 26.4 Failing device: iPhone 11 (iPhone12,1), iOS 16.0.3 Working comparisons: Xcode 26.2 + same iPhone 11 (iOS 16.0.3): works Xcode 26.4 + iPad Pro 11-inch (4th generation) on iOS 26.3: works Regression: Yes. Works on Xcode 26.2. Fails on Xcode 26.4. Same project, same signing setup, same physical iOS 16 device. Minimal reproduction: A minimal sample project with: one iOS app target one app-hosted unit-test target one UI-test target (for comparison; not required to reproduce) Steps for the unit-test repro on a physical device running iOS 16: Build for testing: xcodebuild -project TestProject.xcodeproj \ -scheme TestProject-UnitTests \ -sdk iphoneos \ -destination 'platform=iOS,id=<DEVICE_UDID>' \ -derivedDataPath DerivedData-Device-Unit \ -resultBundlePath Results-Device-Unit-Build.xcresult \ DEVELOPMENT_TEAM=<TEAM_ID> \ CODE_SIGN_STYLE=Automatic \ build-for-testing Run tests without building: xcodebuild -project TestProject.xcodeproj \ -scheme TestProject-UnitTests \ -sdk iphoneos \ -destination 'platform=iOS,id=<DEVICE_UDID>' \ -derivedDataPath DerivedData-Device-Unit \ -resultBundlePath Results-Device-Unit-Test.xcresult \ DEVELOPMENT_TEAM=<TEAM_ID> \ CODE_SIGN_STYLE=Automatic \ test-without-building Note: xcodebuild test (combined build and test) also fails with the same error. Expected result: The hosted unit tests run successfully on the connected physical device, as they do under Xcode 26.2. Actual result: Step 1 (build-for-testing) succeeds. Step 2 (test-without-building) fails immediately (within ~1 second) with: 2026-03-26 11:23:28.683 xcodebuild[51930:731004] DVTDeviceOperation: Encountered a build number "" that is incompatible with DVTBuildVersion. 2026-03-26 11:23:28.725 xcodebuild[51930:730966] [MT] DVTDeviceOperation: Encountered a build number "" that is incompatible with DVTBuildVersion. 2026-03-26 11:23:29.239 xcodebuild[51930:730966] Writing error result bundle to /var/folders/jl/knmkq18x4cg_3w087zgpfldm0000gn/T/ResultBundle_2026-26-03_11-23-0029.xcresult xcodebuild: error: Failed to build project TestProject with scheme TestProject-UnitTests.: Cannot test target “redacted” on “redacted”: Logic Testing Unavailable Logic Testing on iOS devices is not supported. You can run logic tests on the Simulator. Why this looks like an Xcode regression: The same project and same physical iOS 16.0.3 device work under Xcode 26.2. Under Xcode 26.4, build-for-testing still succeeds, so signing, provisioning, and bundle construction appear valid. The failure happens only when Xcode plans or launches the on-device test run. Before the failure, Xcode 26.4 logs: DVTDeviceOperation: Encountered a build number "" that is incompatible with DVTBuildVersion. A newer physical device running iOS 26.3 works under Xcode 26.4 without this warning. The issue also reproduces with a minimal standalone Xcode project, which makes a project-specific configuration problem unlikely. The Xcode-generated .xctestrun files for the passing Xcode 26.2 case and failing Xcode 26.4 case are structurally equivalent, making an .xctestrun format difference unlikely to be the cause.

I received the email confirming that I paid for my Apple account, but my account was never unlocked. I’ve already sent emails and requested phone support, but I haven’t been able to get help through any of these methods. I paid with my Visa card. Does anyone know what to do? Has anyone experienced this?

After having built the SwiftUI project numerous times from Xcode and allowing the plugins after the first build post install using xcodebuild -scheme <SchemeName> build fails with: The following build commands failed: Validate plug-in “SwiftLintBuildToolPlugin” in package “swiftlintplugins” Validate plug-in “OpenAPIGenerator” in package “swift-openapi-generator” How are we supposed to grant the plugins permission to run in the CLI? Everything I'm getting from Gemini is for packages, not apps.

Starting yesterday, the API is returning 302 Moved Temporarily" redirecting the API to Location: https://developer.apple.com/weatherkit/ Is this happening for anyone else? This is incorrect, it should be giving an API JSON response as specified by: https://developer.apple.com/documentation/weatherkitrestapi/get-api-v1-weather-_language_-_latitude_-_longitude_

I paid my subscription from mobile but it's been more than a week and I haven't been able to make it work, I received the email confirmation and if I look at the subscriptions it is there but the developer.apple.com dashbards is asking me to pay again?

With the latest Xcode 26.4 my project fails to compile due to a "compiler unable to type-check in reasonable time" error with a library I've been using for years and has not changed. The library is https://github.com/ngageoint/mgrs-ios and is specifically around this line https://github.com/ngageoint/mgrs-ios/blob/master/mgrs-ios/utm/UTM.swift#L96. Since this isn't my library I can't change it, but again we've been using this library for years now without issue - it was only when Xcode updated this morning that our compilation workflow broke. (Compilation machine is an M3 Pro with 18GB of RAM, so I don't think that's the problem here)

I had already accepted my Apple Developer Program License Agreement since the 20th of march 2026. But your banner stay in my business portal and say : "Le contrat de licence de l’Apple Developer Program a été mis à jour et doit être revu. Afin de pouvoir mettre à jour vos apps existantes et en soumettre de nouvelles, la personne titulaire du compte doit revoir et accepter le contrat mis à jour en se connectant à son compte." Please see if you don't have a bug and let me update my apps.

Hello everyone, I am looking for advice from anyone who has experience with Apple Developer account setup across countries. My Apple account is currently associated with the United States, but I live in Germany and would like my Apple Developer setup to be associated with Germany for tax and administrative reasons. At the moment, I have not enrolled yet in the Apple Developer Program, because I am hesitant to proceed while the account is still tied to the U.S. I want to avoid creating complications later around tax information, billing or account maintenance. My app is essentially ready, so I am trying to make the right decision before enrolling. I would really appreciate guidance on a few points: Has anyone enrolled first and then later changed the country association successfully? Is it better to update the Apple account to Germany before joining the Developer Program? For developers based in Germany, did Apple require anything specific for tax or identity verification? Would enrolling with the account still associated with the U.S. create problems later for App Store Connect, payments or tax forms? I contacted Apple Support on March 21st to clarify this, but I have not yet received a response, so I thought I would ask here in case others have gone through the same process. Any advice or shared experience would be very helpful. Thank you!

Hello, I enrolled in the Apple Developer Program on March 22, 2026 and the payment has already been successfully charged. I also received an invoice the next day (March 23, 2026). However, my account is still not activated, and the system continues to prompt me to complete the enrollment or make the payment again. Is this a normal delay in activation? How long does it usually take for the account to be activated after payment? Do I need to take any additional steps, or should I contact support directly? Thank you for your assistance.

realice un pago para el apple developer program. el cual ya fue cargado el cobro y aprobado por el banco pero no recibo autorización o respuestas de apple solo envían un link para que les envié un correo nuevamente dejándome en un circulo infinito de NADA, al borde de una demanda por parte de los inversionistas que están financiando la app en desarrollo. aunque la atencion por parte del call center es buena no pueden resolver los problemas solo me cambian entre departamentos

I submitted this to Feedback Assistant as FB22331090 and wanted to share a minimal reproducible example here in case others are seeing the same issue. Environment: Xcode 26.4 or Xcode 26.3 Apple Swift version 6.3 (swiftlang-6.3.0.123.5 clang-2100.0.123.102) Effective Swift language version 5.10 Deployment target: iOS 17.0 The sample app builds successfully for normal development use, but archive fails. The crash happens during optimization in EarlyPerfInliner while compiling the synthesized deinit of a nested generic Coordinator class. The coordinator stores a UIHostingController. Minimal reproducer: import SwiftUI struct ReproView<Content: View>: UIViewRepresentable { let content: Content func makeUIView(context: Context) -> UIView { context.coordinator.host.view } func updateUIView(_ uiView: UIView, context: Context) { context.coordinator.host.rootView = content } func makeCoordinator() -> Coordinator { Coordinator(content: content) } final class Coordinator { let host: UIHostingController<Content> init(content: Content) { host = UIHostingController(rootView: content) } } } Used from ContentView like this: ReproView(content: Text("Hello")) Steps: Create a new SwiftUI iOS app. Set deployment target to iOS 17.0. Add the code above. Archive. Expected result: Archive succeeds, or the compiler emits a normal diagnostic. Actual result: The Swift compiler crashes and prints: "Please submit a bug report" "While running pass ... SILFunctionTransform 'EarlyPerfInliner'" The crash occurs while compiling the synthesized deinit for ReproView.Coordinator. Relevant log lines from my archive log: line 209: Please submit a bug report line 215: While running pass ... EarlyPerfInliner line 216: for 'deinit' at ReproView.swift:19:17 One more detail: The same sample archived successfully when the deployment target was higher. Lowering the deployment target to iOS 17.0 made the archive crash reproducible. This may be related to another forum thread about release-only compiler crashes, but the reproducer here is different: this one uses a generic UIViewRepresentable with a nested Coordinator storing UIHostingController.

Was working before, no longer working this week. Trying to sign in to my Claude Pro account via Xcode Intelligence. Goes to browser, I login, and accept authorization in Claude then redirect back to Xcode is reject. Everytime, multiple browsers, and even trying the add "/" that others have noted for other cases.

We're experiencing an issue where the CarPlay Simulator (from Apple Developer Additional Tools) stopped connecting to our iPhones as of March 4th, 2025. The simulator gets stuck indefinitely on "Connecting to phone" and never completes the pairing. Environment App: Oracle Field Service iOS app (with CarPlay support) Tool: CarPlay Simulator from Apple Developer Additional Tools (developer.apple.com/download/all/) Issue start date: Wednesday, March 4th, 2025 Tested on: Multiple Mac machines, multiple iPhones Multiple CarPlay Simulator versions tested What's happening The CarPlay Simulator launches but displays "Connecting to phone" indefinitely. It was working correctly prior to March 4th with no changes on our end. What still works CarPlay functions correctly when the same iPhone is connected to a real car, confirming the issue is specific to the simulator. Troubleshooting steps already attempted Reset permissions and re-added the simulator Forgot the simulator and re-paired it Changed the USB cable Tested on multiple Mac machines Tested on multiple iPhones Tried multiple versions of the CarPlay Simulator Confirmed no VPN is in use Confirmed with IT, no OS updates or enterprise restrictions were applied Questions Has anyone else experienced this since March 4th? Was there a change in CarPlay Simulator behavior or a requirement on the Apple side (certificate, entitlement, protocol) around that date? Is there a known workaround or fix?

Hi. Our IT security team have flagged that on many developer machines they see a deprecated version of Python - 3.9.6. I've done some research on this and the general line is, feel free to upgrade the main version of Python on the Mac, but the version of Python which is internally used by Xcode (3.9.6) must be left unchanged. Our IT security team reached out to Apple and have received conflicting information as to if this Ruby 3.9.6 version can be upgraded. One response for example was "I asked my Solutions Engineer and he has come back with the following: We don’t include Python within macOS anymore, we install 3.9.6 with Xcode to support some of the internal tools - but there’s nothing preventing a customer updating that version: https://mac.install.guide/python/update". Does anyone know if it is possible to upgrade to a supported version? Kind regards, Kai.

Subject: Unable to Complete Apple Developer Registration – No Clear Reason Provided Hello, I am currently trying to register for an Apple Developer account, but I keep receiving the following response: "We are unable to process your enrollment for one or more reasons." I contacted support to ask for the specific reason, but the reply I received was exactly the same message: "We are unable to process your enrollment for one or more reasons." According to the emails and support responses, I am unable to get any clear explanation or solution. The app directs me to contact customer service, but customer service only repeats the same message, which makes it impossible to resolve the issue. At this point, I personally cannot think of any possible reason that would cause this problem. Even after reaching out multiple times, including to senior support staff, I still receive the same generic response without any details. This situation feels completely blocked with no way forward. I would like to ask: Is there any way to find out the specific reason for the rejection? Are there any steps I can take to resolve this issue and successfully complete the registration? Any guidance would be greatly appreciated. Thank you.

Hi everyone, I recently enrolled in the Apple Developer Program and completed my payment on Friday, March 20, 2026. However, my account is still showing as pending and hasn't been approved or activated yet. I'm really eager to get my personal finance app, set up for testing, so I wanted to ask if this processing time is normal, or if there is any additional information or document I need to provide to complete the process. Could anyone from the Apple team assist in checking the status of my enrollment? Thank you in advance for your help

My Apple Developer account was registered with a company Gmail address that has since been permanently deleted. Now when I try to log in, I reach the 2FA step but the verification code is no longer sent to my registered phone number. I am completely locked out. Has anyone experienced this or knows how to contact Apple to recover access?

Hi, On a 1920 points wide monitor, running maximized, Xcode 26.4 can't show more than 10 editor tabs at a time. Under the same conditions, Xcode 26.2 adapts tab widths to file names and fits 12-14 tabs. That's 2-4 more files I can see and access at a glance, without extra interaction. How can I get that level of information density back in the Xcode 26.4 editor tab bar? Screenshots Xcode 26.4 (10 tabs) Xcode 26.2 (12 tabs) Xcode 26.2 (14 tabs)
