Hello, I recently submitted my Swift Student Challenge app playground (“Crest”) and realized after submission that I accidentally selected Swift Playgrounds as the software to run it, instead of Xcode 26 or later. My project builds and runs successfully in Xcode 26 using the iOS 26 SDK and simulator. However, when opening the same .swiftpm project in the Swift Playgrounds app on iPad, it does not compile because Swift Playgrounds currently only supports up to iOS 18 SDK and does not support iOS 26 APIs. The submission itself is complete, builds correctly in Xcode, and was submitted before the deadline. The incorrect selection of Swift Playgrounds was an honest mistake during the submission process. I wanted to ask whether reviewers are able to run the submission using Xcode 26 in cases like this, or if there is anything I should do. Thank you very much for your time.

Hello, I am trying to enroll in the Apple Developer Program, but I cannot complete the payment. During the purchase process, I receive the following error: We are unable to complete your order. There was an issue when we processed your order. An invalid value '1549' was provided for State, Province, or Region. My details: Country: Kosovo State/Province/Region: Kosovo Region (selected from the available option) I have verified my information multiple times, but the error appears every time. I have contacted Apple Developer Support multiple times over the past month.I have not received any response (positive or negative). I need to complete enrollment to publish my apps, and this delay is blocking my work.

I’m looking for advice from anyone who has gone through the process of converting an Apple Developer account to an Organization / Company account. I’ve been trying to convert my account for organization and the process has been taking much longer than expected. Apple initially requested documentation to verify both the business and my authority to act on behalf of the company. So far, I have already provided or prepared everything they ask for. At this point, I’ve been waiting for 9 days without much clarity on whether my documents are sufficient

I’m building an iOS app where real money moves based on goal completion results, including transfers between users. I need a real money flow that supports top ups, internal balance updates, and withdrawals. I’m launching in the EU first and want to avoid building the wrong architecture from the start. I’d appreciate practical guidance from anyone who has shipped similar apps: When can external payment processors be used for real money flows? If users can withdraw real money, what compliance requirements are usually needed first? Is it as complicated as I think? This is my first project of this kind, so I want to approach it correctly. Thank you in advance.

I am working on a security research project on macOS (Apple Silicon M5) and trying to use Memory Integrity Enforcement (MIE) to detect heap memory bugs such as use-after-free. I can confirm the hardware supports MTE hw.optional.arm.FEAT_MTE: 1) and the stack sanitizer (-fsanitize=memtag-stack) does work correctly on this machine. The gap is specifically heap tagging through the allocator. Is there any env variables for this?

I would like to avoid the middle man and call Objective C directly from C Currently I do this This is called from a dispatch table in a pure C file _ctx->mt_render_funcs.mtlEnd(_ctx); Which calls this routine in a obj c file .m void mtlEnd(MTRenderContext mt_ctx) { // Call the Objective-C method using Objective-C syntax [(__bridge id) mt_ctx->mt_render_funcs.mtlObj mtlEnd]; } Which ends up here... in ObjC #pragma mark mtlEnd (void)mtlEnd { // vertex buffer size_t size; size = sizeof(Vertex4ColorNormalTex) * _ctx->vert_eng.current_vertex; [_currentRenderEncoder setVertexBytes:_ctx->vert_eng.vertices length: size atIndex: VertexInputIndexVertices]; [_currentRenderEncoder drawPrimitives:(MTLPrimitiveType)_ctx->vert_eng.prim_type vertexStart:0 vertexCount:_ctx->vert_eng.current_vertex]; } It would simplify this to get rid of one call and call ObjC directly. The other idea is I want to use GCD and put a lock / unlock on the call from C to ensure thread safety so I can use GCD to dispatch a thread to do the ObjC routines. I want to stick with C as the foundation so it can be used directly from C or a FFI interface from other languages. But Metal works well in ObjC and I would prefer to use that. Thanks ahead of time.

We are experiencing an issue with ADCertificate auto-renewal on macOS devices enrolled via MDM. Platform: macOS CA: Microsoft AD CS Payload Type: com.apple.ADCertificate.managed Initial certificate enrollment works correctly EnableAutoRenewal is set to true Certificate does not renew automatically as it approaches expiry We would like to confirm: Are there any known issues with macOS ADCertificate managed payload auto-renewal, particularly with Microsoft AD CS environments? Below is the exact payload configuration in use: Thank you.

Hi all, The SSDC states: Challenge submissions are due by Saturday, February 28, 2026, at 11:59 p.m. PST I am curious does this apply to local timezone? I am GMT+0, so would this mean the deadline for GMT+0 is on the 1st of March at 7:59AM? Kind regards, Adam

Has anyone been able to raise a ticket with the support team in the past 48 hours without getting an infinite loader or error on the page?

Hello, I built my app in Xcode and used IOS 26 latest frameworks like Foundation Models. But some of this frameworks don't work properly in Swift Playground(MyApp.swiftpm) and cause crashes. My question is can I submit a MyApp.xcodeproj file and choose Xcode 26 as a software to run my app ? Thank you in advance.

I installed the latest build of Tahoe (25E5218f) yesterday on our test machine, an M1 Pro MacBook Pro and have been having a hard time getting my WiFi network to work. It's especially noticeable in Mail and Safari. Mail shows it can't connect to the designated server, and Safari simply can't connect to most sites. None of my other devices or computers are having problems, so I have to assume it's this last build that is the culprit. When I tether to my iPhone Air, everything pops back into place and I can access Mail and use Safari. I've reported the problem with FBA, but wanted to know if anyone else is experiencing the same thing.

I develop and build the DeepSkyStacker application on an M4 Mac Mini. A user reports that with a given set of data files and application settings, that it crashes on his M4 MAX. He sent me his data files, and I can't provoke a crash on my M4. He also sent an App Crash report file which I attach. Any insight into the likely cause of the problem will be appreciated (yes, I know it is a segfault in code called from Avx256Stacking::pixelPartitioning - probably a lambda ...). dss-6.1.3-crash.log

Hello everyone, I have already submitted my app playground for the Swift Student Challenge. After submission I noticed a few things I would like to improve and fix. Is it possible to withdraw my current submission and then immediately resubmit an updated version? Any clarification (especially from Apple staff or anyone who has done this before) would be very helpful. Thank you!

I installed the new 26.4 ios and now can't compose or reply to emails on the Gmail app. I tried restarting my phone and uninstalling and reinstalling the app, but nothing helps. How can I fix this?

Hello Apple Developer Community, I am planning to participate in the Swift Student Challenge 2026. However, while reviewing the application form, I noticed that my country of residence is not listed in the address dropdown menu. I would like to clarify the correct way to proceed in this situation to avoid disqualification: Is it permissible to use the address of a relative who lives in a supported region as my contact address? Is filling out the shipping address mandatory for the initial submission, or is there an option to proceed without it? I want to ensure I fully comply with the Terms and Conditions. Any guidance or advice would be greatly appreciated. Thank you!

Hardware: • Mac Studio (M1 Ultra) • Apple Silicon • Sufficient free disk space (~35GB+ available) • SIP enabled • 4 local Time Machine snapshots present Current System: • Already running macOS Tahoe beta • Attempting upgrade to macOS Tahoe 26.4 Beta (Build 25E5207k) Primary Issue: Software Update downloads successfully, then moves to “Preparing…”. It stalls at “About 5 minutes remaining” for ~10–15 minutes and fails with: “Failed to prepare the software update. Please try again. An error occurred while downloading the selected updates.” The error appears network-related, but download always completes. Observed Behaviour: • “Checking for Updates” completes in <3 minutes. • softwareupdated and mobileassetd CPU usage <1%. • softwareupdate --history shows no record of the failed beta install. • No excessive system load or obvious disk pressure. Steps Already Attempted: 1. Standard Software Update retries • Multiple download/retry cycles from System Settings. • Same Preparing failure every time. 2. Permissions / Disk Access • Granted Terminal Full Disk Access. • SIP remains enabled. • Some system-protected locations still return “Operation not permitted”. 3. Cache / State Cleanup Attempts • Removed /Library/Updates/*. • Cleared temporary softwareupdate folders under /private/var/tmp. • Attempted MobileAsset cache cleanup where permitted. • Killed softwareupdated and mobileassetd processes (auto-restarted by launchd). 4. Beta Channel Reset • Turned Beta Updates OFF in System Settings. • Rebooted. • Re-enabled Beta Updates. • Forced catalog refresh via softwareupdate -l. 5. Snapshot Check • tmutil listlocalsnapshots / shows only 4 snapshots (normal range). 6. Full Installer Workaround softwareupdate --list-full-installers shows: • macOS Tahoe Beta 26.4 (25E5207k) • Tahoe 26.3 / 26.2 / 26.1 • Sequoia / Sonoma / Ventura / Monterey installers Downloaded installer via: softwareupdate –fetch-full-installer –full-installer-version 26.4 Installer downloaded correctly: /Applications/Install macOS Tahoe Beta.app 7. startosinstall Method (Apple Silicon optimized) Attempted install with: sudo “/Applications/Install macOS Tahoe Beta.app/Contents/Resources/startosinstall” –user –agreetolicense –nointeraction –forcequitapps –rebootdelay 30 –passprompt Authorization succeeds, installer begins preparing, but installation still ultimately fails. Additional Notes: • CPU usage remains low during failure. • No excessive snapshot count. • Error messaging consistently references download/network even though download completes. • Issue appears to occur during cryptex/asset preparation phase rather than initial download. Question for Apple / other developers: Has anyone else seen Tahoe 26.4 beta fail specifically during the Preparing phase on Apple Silicon (especially Ultra-class chips)? Looking for confirmation whether this is a known MobileAsset or cryptex staging issue, or if logs indicate a deeper APFS / volume-owner authorization problem.

Hi everyone, I’m considering integrating External Payments into my iOS app. I’ve done some research, but I’m finding it difficult to pinpoint the exact commission rates for different regions. For those of you who have already implemented external payment links: Could you share what the actual fees paid to Apple look like in your specific Geos (e.g., US, EU, or others)? Does the total cost—including Apple's commission and the payment processor's fee (like Stripe)—end up being significantly lower than the standard 15-30% IAP?

I’m building a Swift Playgrounds app (.swiftpm) in Xcode 26.2 and I consistently see this warning, even on brand-new Swift Playgrounds apps created from the default template: “Skipping duplicate build file in Compile Sources build phase: /Users/.../.swiftpm/Media.xcassets” Everything builds and runs normally and all images/assets appear correctly, so it seems like it’s just an annoying warning. I’ve checked for duplicates and don’t see the asset catalog listed twice, but the warning still appears whenever I add an asset catalog to any playground project in Xcode. Is this warning safe to ignore for submission, and it won’t affect Swift Student Challenge eligibility?

Updated iOS to 26.4. Gmail folders have disappeared in Apple Mail. Can‘t transfer email messages to folders as consequence. Any ideas?
