Reply to Degraded RoomPlan performance
@Vision Pro Engineer Thanks for the reply, Michael Is the following based off what you've heard or do you have videos and files that show the behavior? Mostly based off user testimonial. I think we have recorded a couple instances of this during onboarding sessions, but in those cases, we suspected that screen sharing itself could be contributing to the issue. Do you have any logging in place that is capturing any RoomCaptureSession.CaptureError errors in production? Yes - we track all fatal scanning errors. We haven't noticed an uptick in those. It seems like another developer was able to improve performance by resolving a memory leak. Have you profiled the application when performing multiple scans in a row? We have done some profiling over the years, but it's difficult because the act of profiling itself severely degrades scanning performance. We have noticed that RoomPlan itself seems to cache/retain resources after scanning even if we have no active references to it. I believe we reproduced this

Difficult to use XCode with Apple Watch
Trying to develop a little Watch app in Swift, and it's been kind of a miserable experience. I constantly get transport errors trying to connect to my watch. I've tried the trick of putting the Mac and the watch on my iPhone hotspot instead of just on the same WiFi network, but I am not sure that actually helps. I can run maybe once or twice, and then the transport error happens and it's very hard to get XCode to recognize the watch again. Also, when it DOES connect, it seems that XCode almost always loses the debugging connection (I just continue, and it IS actually running on the Watch at that point, but no debugger).

Reply to Icon composer icon contains alpha channel upload error
I am also running into this error. (Jan 2026) Xcode v26.2. Icon Composer 1.2 (76) Looking at the release notes above, the issue has not been resolved. Error message I get: Invalid large app icon. The app icon in the asset catalog -app name- can't be transparent or contain an alpha channel. My two cents, it might be due to the automated compiler for the apple App Store distribution SDK they use to review apps quickly before it goes to a real person. This might be due to the new Liquid Glass UX/UI update. I was really excited to try it, but until it gets fixed, I don't think we will get app icons being Liquid Glass anytime soon. Might be due to the fact that, I have the lowest version of iOS 17, which might not recognize it yet. I wonder if it is only for iOS 26 uploads? no idea.

In need of a sample receipt file that uses the SHA-256 hash
My app that's been around since the dawn of the Mac App Store, and which uses its own receipt validation code for 15 years now, recently sometimes triggers a does not support the latest receipt validation requirements error message with my app's users. But I cannot reproduce it, even if I freshly install the app on a M4 Mac running macOS 26.2. So I have a hard time testing my fix. Does someone have a sample receipt file they could share with me (including the MAC from en0 / GUID device ID), or do you know where I can find one that uses the new SHA-256 hash? In fact - when reading https://developer.apple.com/documentation/appstorereceipts/validating-receipts-on-the-device it seems that there's only a SHA-1 after all. So why do some users get the receipt validation requirements message at all? I'm only reading the receipt, decoding the ASN.1 fields and then validate the hash from the receipt (field 5) against the SHA-1 from the GUID+receipt, as always, calling libCrypto's SHA1() function. So, what woul

Sporadic "no route to host" over ssh
When connecting to my M1 mac mini over ssh, certain programs are often unable to reach network destinations in the corporate LAN, although they can usually reach external addresses like www.apple.com. For example, a java program attempting to download from teamcity.dev.corp.com:8111 often fails like: java.net.NoRouteToHostException: No route to host Running the exact same command from the Apple Terminal program works like normal, simply connecting over ethernet on en0 to a TeamCity server inside the same building. Basic diagnostics from the ssh session do not show anything unusual: > traceroute teamcity.dev.corp.com traceroute to teamcity.dev.corp.com (10.21.4.1), 64 hops max, 40 byte packets 1 teamcity.dev.corp.com (10.21.4.1) 1.702 ms 0.409 ms 0.336 ms > route -n get teamcity.dev.corp.com route to: 10.21.4.1 destination: 10.21.4.1 interface: en0 flags: recvpipe sendpipe ssthresh rtt,msec rttvar hopcount mtu expire 0 0 0 0 0 0 1500 1194 > uname -a Darwin mac 25.1.0 Darwin Kernel V

Payment charged but Apple Developer Program account still pending
Hello, I subscribed to the Apple Developer Program and the annual fee was successfully charged from my card, however my membership status is still showing as Pending and has not been activated yet. This is my second message regarding this issue, and unfortunately there has been no progress or response so far. I have already contacted Apple Developer Support and Apple Store Support, and I also attempted to request a refund since the account is still pending and not activated, but I have not received any response at all. This is my first experience with the Apple Developer Program, and honestly it has been very disappointing, especially considering that the payment was taken successfully but the service has not been provided. I would appreciate clear guidance on: • Why the membership is still pending after the fee was charged • Whether the account will be activated or the payment refunded Thank you.

Live Streaming issue for the RTSP
We have the application 'ADS Smart', a companion application for our ADS Dashcam. We offer a feature that lets users stream the live footage of the dashcam cameras through the app. Currently, we are experiencing a time delay of 30+ seconds to see the live stream, i.e the first frame of the live footage is taking around 30+ seconds to display in the app. We are using the MobileVLCKit library to stream the videos in the app. The current flow of the code, Flutter triggers the native playback via a method channel The Dart side calls the iOS method channel /ts_player with method playTSFromURL passing: url(e.g rtsp://.... for live), playerId viewId (stable ID used to host native UI) showControls optional localIp AppDelegate receives the call and prepares networking Entry point: AppDelegate.tsChannel handler for playTSFromURL in AppDelegate.swift. It resolves the Wi‑Fi interface and local IP if possible: Sets VLC_SOURCE_ADDRESS to the Wi‑Fi IP (when available) to prefer Wi‑Fi for the stream. Uses NWPathMonitor and d

Battery Consumption Analysis Using Xcode Instruments
I have been working on battery consumption analysis for my application, and as part of this effort, I wanted to understand how competitor apps behave under similar usage conditions. To do this, I downloaded competitor apps from the App Store and attached them to Instruments via Xcode. I then executed a defined set of manual test scenarios to simulate real user behavior. During these tests, the iPhone was connected to a Mac and charging continuously, which meant that System Power Usage logs were not generated in Instruments. However, I was able to capture detailed metrics such as: Network usage CPU load GPU activity Display and brightness impact Other runtime performance characteristics Since direct battery drain data was unavailable, I used derived analysis (with AI assistance) to estimate approximate power consumption based on the above metrics, assuming real-device (battery-powered) conditions. According to Apple documentation, System Power Usage in Instruments is not directly tied to the device’s battery p

SwiftData CloudKit sync broken on iOS 26
Hi everyone, I’m running into a breaking issue with SwiftData automatic CloudKit syncing on iOS 26, and I'm trying to determine if this is a known regression or a new configuration requirement I missed. The Setup: My setup is extremely standard; I am using the default configuration exactly as described in Apple's documentation here: https://developer.apple.com/documentation/swiftdata/syncing-model-data-across-a-persons-devices The schema is very simple: A single @Model class. No relationships. The Issue: Prior to iOS 26, this exact app was successfully syncing data between devices and to iCloud without issues. Immediately after the iOS 26 update, syncing stopped completely. I haven't changed any code, but when I check the CloudKit Console, I am seeing some BAD_REQUEST errors during sync attempts. Since I am using the default SwiftData sync (and not manual CKRecord handling), I’m not sure how my client code could be triggering a bad request unless the schema requirements have changed under the hood.

Apple Sign-In Fails with Mysterious 404 Error on Non-Existent /appleauth/auth/federate Endpoint
I'm implementing Apple Sign-In in my Next.js application with a NestJS backend. After the user authenticates with Apple, instead of redirecting to my configured callback URL, the browser makes a POST request to a mysterious endpoint /appleauth/auth/federate that doesn't exist in my codebase, resulting in a 404 error.

Reply to Tahoe not displaying new icon made with Icon Composer
The developer documentation for Icon Composer: Add your Icon Composer file to an Xcode project If you create your Icon Composer file outside of Xcode, you can add it to your Xcode project anytime to view your icon in Simulator and on real devices. Just drag the Icon Composer file from Finder to the Project navigator, and Xcode provides feedback on where to drop it in a target folder. No, it doesn’t - it asks how to add it and it adds it at the top level of the navigator but it won’t change how OS 26 displays your app icon in the finder. Alternatively, choose Add Files from the Add button at the bottom of the Project navigator and select your Icon Composer file in the dialog that appears. It asks how to add it and it adds it at the top level of the project but it won’t change how OS 26 displays your app icon in the finder. In the project editor, select the target and the General tab. Under App Icons and Launch Screen, ensure that the name in the App Icon text field matches the name of the Icon Composer file wi

Reply to iOS 26.2 RC DeviceActivityMonitor.eventDidReachThreshold regression?
Update: Found a possible reproduction pattern correlated with plugging the device into power. Reproduced again on a device with no other Screen Time/blocker apps installed besides my own. Attached a second sysdiagnose in my feedback: FB21450954. Observed behavior: DeviceActivityMonitor.eventDidReachThreshold fires even though iOS Screen Time shows 0 minutes for the selected app that day (verified in Settings > Screen Time), and my extension applies ManagedSettings shielding immediately after the callback. Possible repro pattern: iOS 26.2 (23C55). Daily schedule 00:00–23:59. Do not open the selected app(s); leave device idle/locked for hours (0 usage). Plug the device into power while it remains locked/idle. Within minutes, eventDidReachThreshold fires despite 0 Screen Time minutes.

Reply to Tahoe not displaying new icon made with Icon Composer
Same here. The developer documentation says that you can leave the old .icns file in your project and add the .icon file. The old icon should appear on older versions of the OS but the new icon should be displayed by the finder in OS 26. It isn't. I have both types listed in the Info-plist. I deleted the old app version and re-booted the Finder. It doesn't help. I am running MacOS 26 Tahoe. ???
