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 and also the update on the simulator the copy paste feature in the simulators doesn't work anymore and i can't build my app without it because the user has to copy and paste api keys in it. Is there an solution for it I have tried to install an other simulator ios version but then the simulator doesn't work on the the new xcode. Have someone already found an solution?

Just installed the new Xcode 26.4 RC build (17E192) after happily using 26.3 for a few months. I'm noticing some immediate regressions in the Intelligence features: Frequent losing of OAuth token (Claude Agent). This had previously been fixed and now is back. Agent "Thinking" is constrained to thought bubble windows, which are (a) too small to read, (b) not scrollable when thinking goes beyond a few paragraphs. Yes they are tappable when thinking is finished, but this doesn't help. Due to (2), in deep thinking, it's impossible to follow progress beyond the visible window, so impossible to know if the agent is going off the rails. I'm noticing just more general slowness to complete tasks. Not just complete them -- it seems like it takes longer to START tasks, which is really weird. It sits there thinking for longer. Same project, same model as before. Every time you tap "New Chat" it presents both Claude and Codex choices, even if you're only signed into one. This turned a simple single tap into now a required two taps. Overall this feels like a frustrating setback after a very positive user experience in 26.3.

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.

Hello, I enrolled in the Apple Developer Program approximately 20 days ago. My enrollment has been stuck “In Review” since then with no update, no request for additional documents, and no communication from Apple. I submitted a support request 10+ days ago and have received no response. Submit another request without update.. Here is my situation: • Enrollment status: In Review • Support case submitted: ~10+ days ago, no reply • Country: Canada I have verified that: • Two-factor authentication is enabled on my Apple ID • There are no pending agreements in the developer portal • All enrollment information was submitted correctly I kindly request that someone from the Apple Developer Program enrollment team review my case and provide an update or escalation path. Thank you.

I’m seeing a regression in Xcode 26.4 where Interface Builder will not allow connecting IBOutlets or IBActions. Symptoms: The usual gutter circle/dot does not appear next to IBOutlet / IBAction in the code editor Because of this, I cannot: drag from storyboard → code drag from code → storyboard The class is valid and already connected to the storyboard (existing outlets work) Assistant Editor opens the correct view controller file Important: The exact same project, unchanged, works perfectly in Xcode 26.3. I can create and connect outlets/actions normally there. ⸻ Environment Xcode: 26.4 macOS: 26.4 Mac Mini M4 Pro 64G Ram Project: Objective-C UIKit app using Storyboards This is a long-running, ObjC, project (not newly created) ⸻ What I’ve already tried To rule out the usual suspects: Verified View Controller Custom Class is correctly set in Identity Inspector Verified files are in the correct Target Membership Verified outlets are declared correctly in the .h file: @property (weak, nonatomic) IBOutlet UILabel *exampleLabel; Opened correct file manually (not relying on Automatic Assistant) Tried both: storyboard → code drag code → storyboard drag Tried using Connections Inspector Clean Build Folder Deleted entire DerivedData Restarted Xcode Updated macOS to 26.4 Ran: sudo xcodebuild -runFirstLaunch Confirmed required platform components installed Reopened project fresh ⸻ Observations In Xcode 26.4 the outlet “connection circles” are completely missing In Xcode 26.3 they appear immediately for the same code Existing connections still function at runtime — this is purely an Interface Builder issue ⸻ Question The gutter circles appearance has always been flaky in Xcode over the 13+ years I've been using it but now with 26.4 they have completely disappeared. Has anyone else seen this in Xcode 26.4, or found a workaround? At this point it looks like a regression in Interface Builder, but I haven’t found any mention of it yet.

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, 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

I am trying to find a datasheet containing information such as "Key Exchange / Key Agreement / Key Establishment Protocols Used", "Digital Signature Algorithms Used", "Hash Algorithms Used", etc. Any information would greatly appreciated.

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

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?

I have an iOS project based on SwiftUI in which almost all code is organised in Packages. With Xcode 26.2 and 26.3, I can preview all SwiftUI views without issues. With Xcode 26.4, the same previews don't work, in the canvas appears this error message: "Cannot preview in this file. Could not find target description for “TaskListView.swift”". The explanation is: "The list of source files that produce object files did not contain this file to be previewed. Check to make sure it is not excluded using the EXCLUDED_SOURCE_FILE_NAMES build setting." If I add a SwiftUI view to the main project files (not in a package), the preview works as expected. Is it an Xcode 26.4 regression? Or do I need to modify some configuration file?

I'm trying to enroll in the Apple Developer Program as an individual, but I keep hitting a dead end. Every time I attempt to enroll, I get a generic error saying my enrollment could not be completed at this time, with no detail on why. I've reached out to Apple Developer Program Support by email about this but haven't received any response, which is why I'm turning to the community here. On my end, I've ruled out all the common issues. Two-factor authentication is on, I have a valid major credit card on file, I'm enrolling through the web rather than the Developer app, no VPN is active, and my Apple ID is email-based. If anyone from Apple can take a look at my account, or if someone in the community has run into this same error and found a fix, I'd really appreciate the help. Thanks in advance.

I've been unable to enroll in the Apple Developer Program and am posting here after exhausting the standard support channels. The situation: When I attempt to enroll in the Apple Developer Program as an individual, I receive the error: "Your enrollment could not be completed. Your enrollment in the Apple Developer Program could not be completed at this time." No additional explanation is provided. I have contacted Apple Developer Program Support multiple times by both phone and email. Each time, I was told there is nothing they can do. I asked for escalation and was told escalation is not possible. At no point was I given a specific reason for the rejection. One possible cause I identified on my own is that the name on my developer profile may not match my legal name. My Apple ID at appleid.apple.com shows my correct legal name, but I'm unsure whether my developer profile reflects the same. I have not been able to confirm whether this is actually the issue, because support has not told me what the problem is. What I've verified on my end: Two-factor authentication is enabled A valid major credit card is on the account I am enrolling via the web, not the Developer app I am not using a VPN My Apple ID is email-based, not phone-number-based I am an admin (not Account Holder) on a separate organization's developer account, which should not conflict with an individual enrollment The most frustrating part of this experience is the complete lack of transparency. The error message gives no indication of what's wrong, and support agents either don't have visibility into the cause or aren't authorized to share it. I'm willing to correct whatever the issue is - I just need someone to tell me what it is. If any Apple staff can look into my account, or if anyone in the community has resolved this same error, I would be very grateful for any guidance. Thank you.

Hola, compre el 25 de marzo la membresía de desarrollador, pero aun mi cuenta sale pendiente, no subo datos de empresa ya que soy freelance. Cuanto podría tardar la aprobación de la cuenta. Ya mande dos ticket a soporte pero nada responden

I have purchased membership for personal use to see how publishing app works. The cost was taken from the credit card I had given. but when i check my account its still reflecting the same "Purchase your membership" and ask me to purchase again

Hi everyone, I registered for the Apple Developer Program about a week ago and my status is still Pending. I’ve emailed Apple but haven’t received any response yet. Just wondering if others are experiencing the same thing recently, or if there’s another way to follow up. Thanks a lot!

Hi everyone, I am an iOS developer from Ecuador and I am writing to ask if there's any way to fix my issue. After some initial struggling with my phone number not being able to receive Apple verification messages, I was able to register an Apple ID and use that Apple ID to enroll into the Apple Developer Program. Currently, I am stuck at the step of paying the subscription fee. When I try to pay for the 99$ enrollment fee, I receive an "Order Acknowledgement" e-mail from Apple but the payment is never processed. I have tried with multiple debit cards: 2 times with my main crypto debit card emitted from a Hong Kong bank 1 time with a debit card emitted from a local Ecuadorian bank 1 time with a debit card emitted from a US bank In all these cases the result is the same: the same order acknowledgement e-mail but nothing more happens. I even tried asking the support via e-mail (the only method that is supported in my country), but no one replies. Does anyone have any tip on how to overcome this situation?

Hello, I am facing a critical technical blocker regarding the Family Controls (Screen Time API) entitlement for my app extensions. Current Situation: My parent app (com.hayashikento.FocusPact) is already approved for the Family Controls (Distribution) entitlement. However, the associated DeviceActivityMonitorExtension (com.hayashikento.FocusPact.FocusPActMonitor) and ReportExtension (com.hayashikento.FocusPact.ReportExtension) are still pending entitlement approval. Technical Issue: Because the extensions lack the Distribution entitlement, ManagedSettings and DeviceActivity triggers (like intervalWillEndWarning) are ignored by the system when testing via TestFlight or in a non-development environment. As a result, I am unable to verify the core "automatic re-blocking" logic and "usage reporting" features in a real-world scenario. This has completely halted the final QA and TestFlight phase of my project. Requests: Could an Apple engineer verify if these extension IDs can be linked to my existing approved parent app entitlement? Is there a specific process to expedite the "linking" of extensions when the main app is already authorized? App Details: Parent App Bundle ID: com.hayashikento.FocusPact Extension IDs: com.hayashikento.FocusPact.FocusPActMonitor, com.hayashikento.FocusPact.ReportExtension Apple ID (App)6759132649 I have already submitted the web request forms, but the lack of synchronization between the parent app and extensions is preventing my MVP launch. Any assistance would be greatly appreciated. Thank you.

Hello. Our application performs encoding and decoding of large json files which sometimes may take up to 1,5GB of RAM memory. We understand that this may be a problem for devices with low RAM memory (3GB). But before iOS 26.4 we didn't have much occurrences (3 for the last 90 days). Starting from iOS 26.4 it started to crash a lot. Can the reason be that iOS 26.4 occupies more RAM memory so there is less memory left for our app? Or maybe starting from iOS 26.4 there is less RAM memory allocated per app? The crash message is Fatal error: failed to allocate 392 bytes of memory with alignment 8
