Hello, I've discovered a buffer initialization bug in AVAudioUnitSampler that happens when loading presets with multiple zones referencing different regions in the same audio file (monolith/concatenated samples approach). Almost all zones output silence (i.e. zeros) at the beginning of playback instead of starting with actual audio data. The Problem Setup: Single audio file (monolith) containing multiple concatenated samples Multiple zones in an .aupreset, each with different sample start and sample end values pointing to different regions of the same file All zones load successfully without errors Expected Behavior: All zones should play their respective audio regions immediately from the first sample. Actual Behavior: Last zone in the zone list: Works perfectly - plays audio immediately All other zones: Output [0, 0, 0, 0, ..., _audio_data] instead of [real_audio_data] The number of zeros varies from event to event for each zone. It can be a couple of samples (<30) up to several buffers. After the initia

Hello, I'm experiencing a significant delay getting the Family Controls entitlement approved for my Shield Configuration Extension, and I'm hoping someone here can help or has experienced something similar. Background: I'm developing an app that uses the Screen Time API with Family Controls. My main app bundle (lukedev.Bloka) was approved for Family Controls (Distribution) and works perfectly. The Problem My Shield Configuration Extension (lukedev.Bloka.Shield) has been stuck waiting for approval for over 2 weeks: Request ID: 6C8LD22UVM Submitted: November 20, 2025 Status: Still Submitted Current State: Only shows Family Controls (Development) in capabilities What I've Tried ✅ Submitted entitlement request via the proper channels ✅ Contacted Apple Developer Support (case #102762028251) ✅ Verified the main app has full Family Controls approval ✅ Deleted and regenerated all provisioning profiles multiple times ✅ Confirmed the App ID configuration is correct in the Developer Portal The Issue Without Family Contr

Problem description Since macOS Sequoia, our users have experienced issues with multicast traffic in our macOS app. Regularly, the app starts but cannot receive multicast, or multicast eventually stops mid-execution. The app sometimes asks again for Local Network permission, while it was already allowed so. Several versions of our app on a single machine are sometimes (but not always) shown as different instances in the System Settings > Privacy & Security > Local Network list. And when several instances are shown in that list, disabling one disables all of them, but it does not actually forbids the app from receiving multicast traffic. All of those issues are experienced by an increasing number of users after they update their system from macOS 14 to macOS 15 or 26, and many of them have reported networking issues during production-critical moments. We haven't been able to find the root cause of those issues, so we built a simple test app, called FM Mac App Test, that can reproduce multicast issues

Kevin's Guide to DEXT Signing The question of How do I sign a DEXT comes up a lot, so this post is my attempt to describe both what the issue are and the best current solutions are. So... The Problems: When DEXTs were originally introduced, the recommended development signing process required disabling SIP and local signing. There is a newer, much simpler process that's built on Xcode's integrated code-signing support; however, that newer process has not yet been integrated into the documentation library. In addition, while the older flow still works, many of the details it describes are no longer correct due to changes to Xcode and the developer portal. DriverKit's use of individually customized entitlements is different than the other entitlements on our platform, and Xcode's support for it is somewhat incomplete and buggy. The situation has improved considerably over time, particularly from Xcode 15 and Xcode 16, but there are still issues that are not fully res

Hi, I have been using Claude with Xcode 26.1.1 and it was working fine till a couple of days ago, when it started giving me an error message on every query: Message from Anthropic: This request would exceed your account's rate limit. Please try again later. I am on the Pro model, and I can use the Claude.ai website just fine. The usage limits on the website show I've used only 11% of the weekly limit, and 4% of the 'current session'. So I'm wondering if this is an Xcode bug / issue, and if there is a workaround. I have restarted Xcode, restarted the Mac, logged out of Anthropic and logged back in, tried Xcode 26.2 beta as well, but no luck.
