Overview

I recently turned on the enhanced security options for my macOS app in Xcode 26.0.1 by adding the Enhanced Security capability in the Signing and Capabilities tab. Then, Xcode adds the following key-value sets (with some other key-values) to my app's entitlements file. <key>com.apple.security.hardened-process.enhanced-security-version</key> <integer>1</integer> <key>com.apple.security.hardened-process.platform-restrictions</key> <integer>2</integer> These values appear following the documentation about the enhanced security feature (Enabling enhanced security for your app) and the app works without any issues. However, when I submitted a new version to the Mac App Store, my submission was rejected, and I received the following message from the App Review team via the App Store Connect. Guideline 2.4.5(i) - Performance Your app incorrectly implements sandboxing, or it contains one or more entitlements with invalid values. Please review the included entitlements and sandboxing documentation and resolve this issue before resubmitting a new binary. Entitlement "com.apple.security.hardened-process.enhanced-security-version" value must be boolean and true. Entitlement "com.apple.security.hardened-process.platform-restrictions" value must be boolean and true. When I changed those values directly in the entitlements file based on this message, the app appears to still work. However, these settings are against the description in the documentation I mentioned above and against the settings Xcode inserted after changing the GUI setting view. So, my question is, which settings are actually correct to enable the Enhanced Security and the Additional Runtime Platform Restrictions?

Just wondering if anyone ran into this issue. I use NetFSMountURLSync for my application with which I allow the user to use a custom path as a mount point (instead of "/Volumes"). This has worked just fine for at least a decade now, but ... since the Tahoe 26.4 "update" mounting to a custom path only generates errors. Note: Mounting to "/Volumes" works correctly (mountpoint = NIL). Since I'm unaware of any changes; is this a bug introduced by Tahoe 26.4, or should I be using a different function to mount a network share?

I've been working on an app. It uses iCloud syncing. 48 hours ago everything was working 100%. Make a change on the iPhone it immediately changed on the Mac. Change on the Mac, it immediately changed on the iPhone. I didn't work on it yesterday. I updated to iOS26.4 on the iPhone and 26.4 on the Mac yesterday instead. Today, I pull up the project again. I made NO changes to the code or settings. Make a change on the iPhone it immediately updates on the Mac. Make a change on the Mac, nothing happens on the iPhone. I've waited an hour, and the change never happens. If you leave the iPhone app, then return, it updates as it should. It appears that iCloud's silent notification is to being received by the iPhone. Anyone else having the issue? Is there something new with iOS 26.4 that needs to be adjusted to get this to work? Again, works flawlessly with the Mac, just not with the iPhone.

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.

I have an app version (1.2.1) in App Store Connect that is showing "Ready for Review" status. It has an old build (1.2.0, build 4) attached to it. I uploaded a new build today (1.2.1, build 5) and need to swap it in, but there is no "+" or "-" button in the Build section of the version page, and clicking the current build number just navigates to its metadata page. I have tried: Creating a new version (1.2.1) — it auto-populated with the old build Uploading a new build with the correct version string — still no option to swap Looking for a "Remove from Review" button — it does not exist on my page Is there a way to detach the current build and attach the new one, or do I need to delete the version and start fresh? If so, will that affect my existing review thread with Apple? Any help appreciated.

Hi. Your Contact Us page has been down for at least 2 months. There is no way to contact you. I'm locked out of my Apple Developer Account. What can I do here? I'm also shocked that a company as big as Apple has not fixed this page yet. It's kind of crazy.

I published the latest update of my AppKit app in September with macOS 26.0. I just wanted to create a new update, but compiling on macOS 26.4 now fails because of the symbol NSTextAttachment.character which is referenced in my code. The error is Type 'NSTextAttachment' has no member 'character' I've never experienced before that a symbol suddenly is not available anymore without even a deprecation notice from one OS release to the next, let alone a minor release. Is this a bug in macOS or Xcode, or should I start worrying about symbols becoming unavailable anytime?

System-wide deadlock in removexattr from revisiond / APFS We're experiencing a deadlock on certains systems when our software is installed, which is causing side effects in our process (and likely others) such as blocked queues and increased memory usage. According to the spindump, revisiond appears to be holding an exclusive lock within the kernel.

While several EndpointSecurity calls appear in the spindump stack traces, we don't have any evidence that any calls from revisiond were blocked. What we'd really like to to understand what that lock is (appears to be decompressing an object on an APFS volume), what revisiond and APFS are doing with it, and what might cause it to deadlock. Of note, one of our processes is also waiting on that lock, one thread for reading and the other for writing. This issue affects machines running several macOS versions (15.x, 26.x). The machine in the examples is running macOS 26.3 (25D125)

We have an VoiP application, our application can be configured to amplify the PCM samples before feeding it to the Player to achieve volume gain at the receiver. In order to support this, We follow as below. If User has configured this Gain Settings within application, Application applies the amplification for the samples to introduce the gain. Application will also set the AVAudioSessionCategory to AVAudioSessionCategoryPlayback Provided the User has chosen the output to Speaker. This settings was working for us but we see there is a difference in behaviour w.r.t Volume Level System Settings between OS 26.3.1 and OS 26.4 When user has chosen earpiece as Output, then we will set the AVAudioSessionCategory to AVAudioSessionCategoryPlayAndRecord. User would have set the volume level to minimum. When user will change the output to Speaker, then we will set the AVAudioSessionCategory to AVAudioSessionCategoryPlayback. The expectation is, the volume level should be of AVAudioSessionCategoryPlayback what was set earlier instead we are seeing the volume level stays as minimum which was set to AVAudioSessionCategoryPlayAndRecord Could you please explain about this inconsistency w.r.t Volume level.

I have a simple reproducer here: struct ContentView: View { @State private var isOn = false @State private var isPresented = false var body: some View { NavigationStack { Color.blue .toolbar { ToolbarItem(placement: .topBarTrailing) { Button("Press here") { isPresented = true } .popover(isPresented: $isPresented) { Color.green .frame(idealWidth: 400, idealHeight: 500) .presentationCompactAdaptation(.popover) } } } } } } When I tap on the button in the toolbar you can see there is a hang then the popover shows. Then every time after there is no longer a hang so this seems like a bug. Any ideas? I'm using Xcode 26.3 and a iPad Pro 13-inch (M5) (26.4) simulator.

After more than a year since the announcement, I'm still unable to get this feature working properly and wondering if there are known issues or missing implementation details. Current Setup: Device: iPhone 16 Pro Max iOS: 26 beta 3 Development: Tested on both Xcode 16 and Xcode 26 Implementation: Following the official documentation examples The Problem: Semantic search simply doesn't work. Lexical search functions normally, but enabling semantic search produces identical results to having it disabled. It's as if the feature isn't actually processing. Error Output (Xcode 26): [QPNLU][qid=5] Error Domain=com.apple.SpotlightEmbedding.EmbeddingModelError Code=-8007 "Text embedding generation timeout (timeout=100ms)" [CSUserQuery][qid=5] got a nil / empty embedding data dictionary [CSUserQuery][qid=5] semanticQuery failed to generate, using "(false)" In Xcode 16, there are no error messages at all - the semantic search just silently fails. Missing Resources: The sample application mentioned during the WWDC24 presentation doesn't appear to have been released, which makes it difficult to verify if my implementation is correct. Would really appreciate any guidance or clarification on the current status of this feature. Has anyone in the community successfully implemented this?

Are there some requirements to use Notification Content Extensions other than including the target to my iOS app? I have done it, configured it to match a certain category of notifications, but my custom interface doesn’t show up. is there anything I need to configure on my main app? Is that anything that should be changed there, such as disabking its botifications handling? is there any requirement concerning the payload? I tried to disable time sensitive and content-available notifications, but it didn’t help.

Hi everyone, I am facing an issue while configuring an App Clip in App Store Connect, and I am unable to proceed due to a UI crash. Issue When I navigate to the App Clip section under my app version and click on the Subtitle field, the page immediately shows: “We can't process your request.” I am unable to enter any metadata for the App Clip experience. Console Error Previously, I observed the following error in the browser console: TypeError: Cannot read properties of undefined (reading 'appClipDefaultExperience.id')

Title: Apple Developer Program membership still not active after payment (3 weeks) Hello, I purchased the Apple Developer Program membership on February 6, 2026. The payment was successfully charged and the invoice was issued. However, my membership still appears as inactive in my developer account, and I cannot proceed with app submission. I have already contacted Apple Developer Support but have not received a response yet. Has anyone experienced a similar delay or know what else I should check? Details: Purchase date: 06.02.2026 Invoice Number: MC49961752 Apple Order Number: AET2317962 Any guidance would be appreciated. Thank you.

We have an app that controls InDesign Desktop and InDesignServer via hundreds of AppleScripts. Some macOS security updates a while back dictated that we start communicating with other apps via ScriptingBridge. We couldn't afford to convert the hundreds of AppleScripts into direct ScriptingBridge nomenclature, so we opted to keep them as is and instead tell the external apps to: [app doScript:<the script text> language:InDesignScLgApplescriptLanguage withArguments:nil undoMode:InDesignESUMScriptRequest undoName:@"blah"] There are a handful of scripts that we did convert to direct ScriptingBridge. There are times (and under the right circumstances, it's repeatable) when a certain script will have run perfectly dozens of times, and then it will throw errOSAInternalTableOverflow. We create a new SBApplication for every job (which could be a single instance of Desktop or the multiple instances of Server). Why is this error happening seemingly randomly? Is there anything we can do to work around or prevent this?

Hi, I'm using Bitbucket for remote repository. I try to change the Bitbucket App Password used so far to the remote repository with the new API token with scope as the App Password will be deprecated.. I created the API token successfully but I cannot configure it in Xcode. Does someone has already successfully replaced the App Password with the new API token in Xcode? Thank you in advance Jean MacBook Air 26.3.1 Xcode Version 26.4 (17E192)

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. I have a universal app in the AppStore. Can I drop the Intel support and build the app as M only and still have it distributed in the app store? This was a problem the last time I set up my build environment but I am not sure if that is still the case. Regards

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!
