Where is Find My network Supplementary Agreement?
I am new to Find My network development and i am going to use Nordic solution for my FMN application. I have asked the MFi representative to enable the "Find My network" in our MFi portal. But there are just a sets of PDF in the "Find My network" under "Technology" in MFi Portal. Is there any Find My network Supplementary Agreement in MFi portal? Is it a PDF or where can i find it? Because I need to sign this document back to Nordic solution representative. But it seems there are no such FMN Supplementary Agreement.

Instruments Crash using swiftui instrument
Instruments is crashing when the swiftui instrument is stopped (the session is finished) and the transfer begins from device to device: Crashed Thread: 11 Dispatch queue: com.apple.swiftuitracingsupport.reading Exception Type: EXC_BAD_INSTRUCTION (SIGILL) Exception Codes: 0x0000000000000001, 0x0000000000000000 Termination Reason: Namespace SIGNAL, Code 4 Illegal instruction: 4 Terminating Process: exc handler [1633] I've tried removing derived data, reinstalling xcode, updating xcode (I originally thought this might be the issue -- I needed to update to 26.2 from the 26 RC -- the update didn't fix crash or change the crash report), and restarting both devices. I'm running Instruments/Xcode 26.2 on a MacBook Pro 15" (2018) running Mac OS 15.7.2 (24G325) with an iPhone 16 Pro Max running 26.2. Hoping someone else might have seen this or could help me troubleshoot. I find the swiftui instrument be helpful and like to use it :) I can post a complete crash report as well.

Getting Valgrind to run on macOS 10.15 Catalina, reboot
I posted about this about 5 years ago, and now at last it's close to being finished. The main problem that I now have is related to matching up DWARF debuginfo and global variables. This works fairly well on macOS 10.14. On 10.15 much less so, and I think that the reason is how the macho data is mmap'd. When Valgrind runs it does the job of the OS and loads the guest exe into memory. It'll then load and run dyld in Valgrind. I can get memory map debug traces. In one test with a problem I see 4 load segments. __DATA_CONST and __DATA both have prot 3 (RW) so we load them RW and not R then RW. Then I think that dyld munmaps and re mmaps the _DATA_CONST segment as RO. Valgrind works based on mmaps triggering reading debuginfo. I don't think that it handles munmap correctly. I need to debug that a lot more - I can see the changed mappings in the debug output but I don't see exactly what is happening with munmap and mmap (unless dyld is doing that on a section by basis). Does what I'm saying about the mappings make any sense?

Xcode 26.1 re-release?
The developer downloads page now lists an Xcode 26.1 which was released on 11th Dec (the original Xcode 26.1 was posted on 3rd Nov). Strangely, this new Xcode 26.1 has a CFBundleShortVersionString of 26.1.1, and a DTXcodeBuild of 17B55 % ls -ln total 4413136 -rw-r--r--@ 1 503 20 2259523057 16 Dec 19:01 Xcode_26.1_Apple_silicon.xip % xip --expand Xcode_26.1_Apple_silicon.xip xip: signing certificate was "Software Update" (validation not attempted) xip: expanded items from "/Users/me/Downloads/temp/Xcode_26.1_Apple_silicon.xip" % plutil -p Xcode.app/Contents/Info.plist | grep CFBundleShort "CFBundleShortVersionString" => "26.1.1" % plutil -p Xcode.app/Contents/Info.plist | grep DTXcodeBuild "DTXcodeBuild" => "17B55" 17B55 does correspond to the original Xcode 26.1 final release. The Xcode 26.1.1 release that was previously posted had a DTXcodeBuild of 17B100, though. The pairing of 26.1.1 and 17B55 looks new and probably a packaging error?

Controlling UIDesignRequiresCompatibility via Remote Config
Hello, I am currently in the process of gradually adding support for LiquidGlass to my app. The transition is taking place incrementally, i.e., new screens and minor features are gradually being adapted to the new design and already deployed. Currently, the old design is still active via the feature flag UIDesignRequiresCompatibility, as the existing UI should remain locked for the public app store version until the transition is complete. My challenge is as follows: I would like to work with the new LiquidGlass design during development without having to manually change the UIDesignRequiresCompatibility flag with each deployment. Ideally, I am looking for a solution where: • the new design is only activated for me (e.g., specific account or specific devices) • the old design remains active for all other users • the App Store version can be delivered unchanged So my question is: Is it possible to control UIDesignRequiresCompatibility via remote config or server-side logic in order to activate the new design specifically for certain users or devices? I have observed similar behavior on WhatsApp—two devices with the same app version, but only one shows the new design. This suggests server-side or remote config-based control. Do you have any experience or recommendations on how to implement something like this cleanly? Kind regards Heinz

Real Time Spatial Video Streaming with Vision Pro
Hello, I am trying to build an AVP app for real-time "zero-latency" spatial video streaming. I am trying to figure out, on a high level, the best way to do this. Currently this is my method: Server sends stereo images via a WebRTC service (ie, livekit) The WebRTC stream is converted to a CVPixelBuffer, writes them to file, plays via AVPlayer, and applies a VideoMaterial to a plane entity. However, this is a bit hacky and it seems like this won't be compatible with Apple's spatial experinces. To my understanding, Apple supports HLS streaming for spatial experiences and APMP content. However, HLS (and even Low Latency HLS) introduces a second or more of latency, likely do to the segmentation nature of HLS. Thus, HLS will not work for us. Some other alternatives I've thought of are streaming the live stream video via webrtc from the server to a local computer in the AVP's network, and then using LL-HLS to stream from the local computer to the vision pro. Still, it seems like this would introduce latency on the order of seconds. Is my current approach the best way to implement this? Or could anyone suggest a better way, perhaps something compatible with AVP's spatial experiences

Is Xcode's predictive code completion model has some censoring?
It seems Xcode's predictive code completion model is censored. Specifically, when typing the word "torrent," the model stops working completely. It doesn't matter whether the word is written directly in the code or in a comment. It could also be part of another word, such as "qBittorrent." In either case, the model stops working. Reproducing this issue is fairly simple. Create a Swift file and type the word "torrent." The model will stop generating code. Xcode Version 26.2 (17C52) Predictive Code Completion Model: [com.apple.fm.code.generate_small_v2.base: 700.0.81600.13.202379,0] [com.apple.fm.code.generate_safety_guardrail.base: 1.6.81619.13.202072,0] [com.apple.gm.safety_deny.input.code_intelligence.base: 32025010.20251009.91600.100.1651,0] [com.apple.gm.safety_deny.output.code_intelligence.base: 32025010.20251009.91600.100.1651,0] (Installed)

AR location errors on cellular + WiFi model iPad with device connected to Wi-Fi
I am developing an Augmented Reality (AR) navigation application for the iPad, utilizing the ARCL library to place Points of Interest (POIs) in the real world. The application's behavior varies significantly based on the device's networking configuration: Cellular Network (Expected Behavior): On an iPad with a cellular modem, when using the cellular network, all POIs are placed accurately with correct orientation. Wi-Fi Only (Expected Behavior): On a Wi-Fi-only model (no GPS chip), POI placement is inaccurate, confirming the need for an external GPS receiver for that hardware configuration. Cellular + Wi-Fi (Anomalous Behavior): The iPad is a cellular model (equipped with GNSS/GPS). The device is connected to a Wi-Fi network (enforced via an MDM profile, preventing the user from disabling Wi-Fi). When actively connected to this specific Wi-Fi network, the AR POIs consistently display with an incorrect orientation and placement, even though the device hardware has a dedicated GPS chip. The placement error strongly suggests that the device's determined location or heading is erroneous. It appears that the active Wi-Fi connection is somehow interfering with or overriding the high-accuracy GNSS/GPS data, leading to a flawed Core Location determination that negatively impacts the ARCL world tracking and anchor placement. Has anyone experienced a scenario where an active Wi-Fi connection on a cellular iPad model causes Core Location to prioritize less accurate location data (potentially Wi-Fi-based location services) over the device's built-in GNSS/GPS, resulting in severe orientation errors? We observed that on Apple map(native application) as well it is showing wrong location and orientation when it is connected to WiFi

Trouble setting up watches to use TestFlight that are AWFK configured
I am developing a simple watch app and I use my personal watch for development with Xcode. Personal watch is series 10 gps only. I have two other watches that I want to use for testing the app, but not needing them to be connected to Xcode. The test watches have cellular option, and I need a cell plan per watch because the watches need to be standalone, not counting initial setup. To get the standalone cell plan the watches need to be configured using AWFK. Here is what I have tried/current issues. I switch between all three watches on my phone using the watch app. Originally tried to put test watches in developer mode, thinking I would connect to Xcode, developer mode is not available when watch is setup using AWFK. Pushed the watch app to apple connect, setup TestFlight group, added the test users and my phone user, accepted invites TestFlight is installed on my phone, I see the testflight setup for the watch app I set a test watch using watch app on the phone, run install for the test app from TestFlight on the phone, spinner moves for awhile then goes back to Install. I am not able to get the watch app installed on the test watches from the phone. Is what I am attempting to do supported? I haven't found much specific documentation on this. If I pair the test watches as regular watches, set them to developer mode, can I pair them again as AWFK and will developer mode survive the switch? Or is there something really simple that I'm overlooking? Appreciate any help that can be extended.

How to delete iOS simulator runtimes?
There are multiple iOS simulator runtimes located at /System/Library/AssetsV2/com_apple_MobileAsset_iOSSimulatorRuntime which I don't need. I tried the following approaches to delete them but not working. Xcode > Settings > Components > Delete (It can delete some but not all of them) xcrun simctl runtime list (It doesn't show the old runtimes) sudo rm (Operation not permitted) sudo rm -rf cc1f035290d244fca4f74d9d243fcd02d2876c27.asset Password: rm: cc1f035290d244fca4f74d9d243fcd02d2876c27.asset/AssetData/096-69246-684.dmg: Operation not permitted rm: cc1f035290d244fca4f74d9d243fcd02d2876c27.asset/AssetData: Operation not permitted rm: cc1f035290d244fca4f74d9d243fcd02d2876c27.asset/Info.plist: Operation not permitted rm: cc1f035290d244fca4f74d9d243fcd02d2876c27.asset/version.plist: Operation not permitted rm: cc1f035290d244fca4f74d9d243fcd02d2876c27.asset: Operation not permitted I have two questions: Why "xcrun simctl runtime list" is unable to list some old runtimes? How to delete them?

Forecasts missing in WeatherKit
I am using the WeatherKit REST API with hourlyStart/hourlyEnd parameters to request up to 240 hours of forecast data. However, when requesting later in the day, the API returns fewer than 240 hourly forecasts — e.g., 239 at 08:00, 238 at 09:00, etc. and goes up to 224 for 23:00 It appears the returned list is contiguous but truncated at the end compared to the full 240-hour window. I have also tried getting the data after sometime, like 09:00 data at 09:45 but still was missing the same data at the end. Is this expected WeatherKit behavior or a bug? If it’s expected, is there documentation explaining how the “forecast horizon” is determined and when it is updated? Thank you.

Critical CallKit Issue: Audio Route Flapping due to reason: 3 (CategoryChange) after User Toggle
I am facing a severe audio routing instability issue when using CallKit and the Zego Express SDK on iOS. The problem is that the audio route immediately reverts from the Speaker back to the Earpiece, effectively disabling the Speaker button functionality.📝 Observed BehaviorWhen the user taps the native CallKit Speaker Button, the audio route is correctly changed to the Speaker, but then instantly flips back to the Receiver (Earpiece), as shown in the system log captured via AVAudioSession.routeChangeNotification monitoring.🧾 Log Evidence (Flapping Occurs in 0.4 seconds)The following log snippet clearly illustrates the system overriding the user's action (reason: 4) with an unexpected CategoryChange (reason: 3) event: TimestampComponentReason CodeDescriptionRouteIs Speaker16:31:18.009[CallKitManager]4Override (CallKit/ControlCenter)Loa ngoài (Speaker)true16:31:18.411[CallKitManager]3CategoryChangeThiết bị nhận (Receiver)false

Terminated Account Remaining Balance Payout
I recently had my developer account terminated. In the final termination email, it said: "If applicable, no further payments will be made to you pursuant to Section 7.1 of the Paid Applications agreement (Schedules 2 and 3 to the ADP Agreement)." I've talked to multiple different developers who also had 3.2f account terminations. Some of them say that they got all their remaining earnings paid out 3-6 months later. Others have said that Apple just kept the money forever. How can I find out if Apple will pay me my account's remaining balance? When I got the original pending termination notice, I was still able to log into App Store Connect to view everything. But immediately after I got the final termination notice email, I could no longer even log into App Store Connect. Could anybody please help me? I'm dependent on the unpaid earnings as a young 21 indie developer. Thank you!! :)
