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.

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.

When I go to the leadership section, I have 8 currently active leaderboards. When I select "manage scores and players" I see 9 leaderboards, from which 5 are legacy and my 4 new ones are not listed (also it comes in a very old design). New players will score in the 4 new leaderboards but I need to remove the top score which was the developer score, to give them a chance, but the new leaderboards are not accessible.

I've purchased the apple developer program a few days ago. It's still pending. I called support but they just advised to send emails. Case ID: 102848926959 Please fix it.

While analyzing system power on an M4 Max under GPU-heavy compute workloads, I noticed that the the GPU power reported by powermetrics does not come anywhere close to total system DC power reported by the SMC counter PDTR (as used by utilities like mactop). For example, in a heavy GPU workload, powermetrics would report a 65W idle-load delta on the GPU, but at the same time system DC power would rise by 179W, leaving 114W or nearly 2/3 of total system DC power on a Mac Studio M4 Max unexplained. From measurements, the difference appears to correlate with the amount of on-chip data movement (for example, varying bytes-per-FLOP in the workload changes the observed gap). Using SMC and IOReport, I was able to reverse engineer an energy model for the GPU that explains almost all of the energy flow with less than 2% error on the workload I studied. The result is a simple two-term energy roofline model: P_GPU (GPU_combined term in the plot) ≈ a * bytes + b * FLOPs with: ~5 pJ/byte for SRAM movement ~2.7 pJ/FLOP for compute. Has anyone observed similar behavior, or is there guidance on how GPU power reported by IOReport/powermetrics should be interpreted relative to total system power? In particular, I’m interested in whether certain classes of GPU activity may not be attributed to the GPU component in IOReport.

I've got a Project with a bunch of frameworks, each of which has a static library version of itself (for compiling command-line tools that also use the code). Compiling the frameworks goes fine. Compiling one of the static libraries (A Mime-parsing framework) is giving me the rather odd message that a bunch of symbols are ambiguous, but the ambiguity resolves to the same symbol in the error-message... ~/src/E3Mail/Frameworks/E3Mime/E3Mime/Message/MIME/E3AppPkcs7Part.m:57:18: error: reference to 'E3_SMIME_ENVELOPED_DATA' is ambiguous 57 | case E3_SMIME_ENVELOPED_DATA: | ^ In file included from ~/src/E3Mail/Frameworks/E3Mime/E3Mime/Message/MIME/E3AppPkcs7Part.m:9: ~/src/E3Mail/Frameworks/E3Mime/E3Mime/Message/MIME/E3AppPkcs7Part.h:17:2: note: candidate found by name lookup is 'E3_SMIME_ENVELOPED_DATA' 17 | E3_SMIME_ENVELOPED_DATA, // Enveloped data | ^ In module 'E3Mime' imported from ~/src/E3Mail/Frameworks/E3Mime/E3Mime/Message/MIME/E3AppPkcs7Part.h:8: ~/src/E3Mail/Frameworks/E3Mime/E3Mime/Message/MIME/E3AppPkcs7Part.h:17:2: note: candidate found by name lookup is 'E3_SMIME_ENVELOPED_DATA' 17 | E3_SMIME_ENVELOPED_DATA, // Enveloped data | ^ ... and again ... ~/src/E3Mail/Frameworks/E3Mime/E3Mime/Message/MIME/E3AppPkcs7Part.m:62:18: error: reference to 'E3_SMIME_SIGNED_DATA' is ambiguous 62 | case E3_SMIME_SIGNED_DATA: | ^ In file included from ~/src/E3Mail/Frameworks/E3Mime/E3Mime/Message/MIME/E3AppPkcs7Part.m:9: ~/src/E3Mail/Frameworks/E3Mime/E3Mime/Message/MIME/E3AppPkcs7Part.h:18:2: note: candidate found by name lookup is 'E3_SMIME_SIGNED_DATA' 18 | E3_SMIME_SIGNED_DATA, // Signed data | ^ In module 'E3Mime' imported from ~/src/E3Mail/Frameworks/E3Mime/E3Mime/Message/MIME/E3AppPkcs7Part.h:8: ~/src/E3Mail/Frameworks/E3Mime/E3Mime/Message/MIME/E3AppPkcs7Part.h:18:2: note: candidate found by name lookup is 'E3_SMIME_SIGNED_DATA' 18 | E3_SMIME_SIGNED_DATA, // Signed data | ^ ... and again, etc ... .

And when I click on the error adornment in the editor pane, the errors disappear. It still won't build the project, though. I just get the same errors the next time I press CMD-B. Can't upload a short screen-capture of that, so I put it the movie at http://0x0000ff.co.uk/mov/phantom-errors.mov.

I am trying to preview my SwiftUI views but Xcode Preview Canvas failing. I tried everything that I found at internet but nothing works. Finally I created a new iOS project that contains only a view import SwiftUI struct ContentView: View { var body: some View { VStack { Image(systemName: "globe") .imageScale(.large) .foregroundStyle(.tint) Text("Hello, world!") } .padding() } } #Preview { ContentView() } Even this view cannot be previewed The error is Simulator was shutdown during an update Simulator [3E0DB935-C4C2-4566-BA48-8E21564C207C] failed to boot and may have crashed. I tried to restart xCode, restart Mac, download ios 26.0 sdk and created a simulator with that sdk but nothing helped. Do you have an idea?

Hello, I am facing a critical issue where the Family Controls (Distribution) entitlement is not being applied to my app extensions, despite the main app ID being approved. Main App ID: com.hayashikento.focuspact (Approved on March 13) Extension ID 1: com.hayashikento.focuspact.ShieldActionExtension (Pending/Not visible) Extension ID 2: com.hayashikento.focuspact.ShieldConfigurationExtension (Pending/Not visible) I have submitted requests multiple times, but the entitlement does not appear in the "Capability Requests" for these extensions in the Certificates, Identifiers & Profiles portal. Furthermore, I am unable to contact Developer Support because the "Contact Us" form on the developer website consistently shows a "Request error" or freezes on the submission page. Since I am completely blocked from TestFlight distribution, could someone from Apple please look into my account (Team ID: UHG4J7F7NH) and manually sync these entitlements? Thank you for your help.

Hello, Apple Developer Support Team, I registered for the Apple Developer Program using the Developer app on my Macbook. Payment and identity verification were completed successfully. Nevertheless, the phrase "Complete Your Purchase" still appears when I check in online, and my registration status is listed as Pending. Even though I've already finished the enrollment procedure, the system seems to be requesting me to do it again. I already have opened a case with Case ID: 102848342160 but had no response. Would you kindly check my account and let me know how my registration is going right now? I appreciate your help. Kind regards, Bua.

When working in parallel on 2 projects (i.e. a server and a client app project). The Claude Code agents in those projects should be able to communicate with each other to improve the flow of information (i.e. changes in models, DTOs). The developer should supervise the communication and can block, if necessary.

This just started happening today out of nowhere. Instead of only the project I’m working on appearing in Source Control, every project inside my Xcode projects folder is now showing up in the Source Control navigator. This is happening in both the Changes and Repositories tabs.

I signed up for membership on Monday March 16th. It took my credit card info and put me in ‘Pending’ state. My cc was charges $99 but when I go back to my account it has a box for me to continue to signup for membership where it asks to charge my account again. I tried using the account support where it asks to with provider a phone number to call me or to send an email. I chose phone. It called me almost immediately but it was already in the middle of explaining options to select. And before I could get to my keypad it said that my time had expired. ‘Good Bye’. I went back to try again and saw a case id assigned. But it would not let me do another callback or email. Instead I got “Error processing your request”. I’ve tried for 3 hours trying to find another channel to get help. They have my money and I dont have membership. can anyone suggest where I go from here?

I would like to have the option to keep my xcode project open regardless of closing all tabs using cmd + w.

I am in the end stages of creating my app and apple is saying I need to include Business number and GST (RT) number - I'm Canadian and not sure how this applies to developers in other countries. Just wondering if any developers from Canada can shed light on this process of getting a GST number, the CRA is saying you can create a GST account/number once your business reaches $30,000 is revenue so its seems different than what Apple is saying to do. This is my first time creating an app and I'm a solo developer.

Help. I paid for the subscription 2 days ago (50 hours ago), the account still hasn't been activated. Support doesn't answer for 2 days either. I called, they said they couldn't help in any way. What to do??? Serial number: 2-8711222928 Order ID: MTFKZHZFFT

Hi everyone, I’m currently trying to set up a business account on the Apple Developer Console, and I’ve run into a really frustrating issue. Last month, I was asked to submit additional documents for verification. I submitted everything as requested and received a confirmation email: “Thank you for providing the documents we requested. We will review them and follow up with you within two business days.” However, weeks passed with no update. About 1–2 weeks ago, I reached out to support again. I was asked to re-submit the same documents, which I did. Once again, I received the same confirmation email stating a response would come within two business days. It’s now been 7 days since that second submission, and still no response. At this point, I’m not sure what I’m doing wrong or if this is just a delay on Apple’s side. What’s more confusing is that we’ve successfully created developer accounts on other platforms (like Google Play) using the same business information and DUNS number, with verification completed in under 24 hours. Has anyone experienced something similar with Apple Developer business verification? Is there something specific Apple looks for that I might be missing, or is this just a backlog/delay issue? Would really appreciate any insights or advice. Thanks 🙏

Is it possible to change the order of Cards in a Trends/Units screen like that (in a such order): Free In-App Paid Free iOS/watchOS/tvOS Free macOS In-App iOS/tvOS In-App macOS Paid iOS/watchOS/tvOS Paid macOS

Good Morning Everyone As per the title, got my DUNS Number (what a mission!) and switched to an organization. It's been a couple of days and there's Radio Silence from Apple. Any tips to speed the process along? Thank you!

As you can see the source directory as a whole is not visible you can only edit pages.

Hi, I am working on app at the moment that uses Icon Composer for all of its icons and variations. I want to add an iMessage App to my project however I get validation errors from App Store Connect even if I add an imessage app to my asset catalog and include all app icon assets. Is there any way to do this at the moment natively with Icon Composer? If not how do I manually overwrite the icon JUST for iMessage and not for my entire iOS app?
