Reply to Bug: Wi-Fi Aware (NAN) Subscriber Mode: nwPath.availableInterfaces Does Not Include nan0 Interface After Successful Peer Connection
Thanks for your reply!We have successfully connected an iOS device with a non-iOS device via Wi-Fi Aware, and established multiple TCP connections. However, we still have a throughput issue: when the iOS device acts as a Subscriber, and sends an HTTP request over an already-established TCP connection to download resources from the non-iOS device, we observe slow download speeds — only around 20 MB/s. We compared iOS system logs and found: When the non-iOS device connects to iOS, the timeslot bitmap used is ff ff 00 00 ff ff. When iOS connects to iOS, all timeslots are used. Could this be the reason for the large difference in transmission rates? Is this caused by configuration, or what leads to the reduced timeslot allocation? Log 1: Non-iOS device connecting to iOS default 16:33:33.204715+0800 kernel wlan0:com.apple.p2p.nan0: Availability: map 0, channel 6 (20M), timeBmap: 1111 1111 1111 1111 0000 0000 0000 000

Reply to Triggering “realtime” mode for peer-to-peer WiFi via awdl to fix jitter problems
[quote='819926021, craigc123, /thread/819926, /profile/craigc123'] is there any way to programmatically trigger “realtime” mode? [/quote] No. Well: Not as an API that’s documented to have that effect. It might be possible to find some API that does it as a side effect, but that would be an implementation detail and thus not something you’d want to rely on. And there’s the Wi-Fi Aware option, but you’ve ruled that out. I think you should create a prototype based on Wi-Fi Aware and see if it achieves the latency goals that you need. If it does, you can then factor that into your decision as to how to proceed here. And apropos that, you wrote: [quote='819926021, craigc123, /thread/819926, /profile/craigc123'] I am looking for a solution that works … on previous OS versions. [/quote] Note that Wi-Fi Aware requires iOS 26 and specific hardware. The main framework doc page has the list.

Help with getting info for an WIFI USER EXPERIENCE APP
Hi I’m working on an app Called Wiux ( already on Android ) but one of my clients has a company with all iPhones so I need to develop the app for iOS, but I’m facing A huge wall, it’s an proactive wifi user experience monitor for distributed networks and the idea is that the app its sending every minute info about connectivity RSSI, which network , if is 2,4ghz or 5ghz channel used and device usage cpu ram etc but I find that is no getRSSI ( and I really need that data ) but some aps like iWifi or WiFi probe has that data and it works I check the reads with a phisical probe and my app on android and values match. i think maybe with NEHotspotHelper I could get the data but I don’t know how to ask to use it or if exist a dependency for quality monitoring that allows me to access that thow o info. ( And probably in the near future I face the same problem with LTE ( that I’m also monitoring with the app on Android and I think is going to be a problem on iOS )

Reply to Help with getting info for an WIFI USER EXPERIENCE APP
iOS has a limited set of Wi-Fi APIs. See TN3111 iOS Wi-Fi API overview for a summary of what’s available. Regarding signal strength specifically, I address that head on in iOS Network Signal Strength. In short, you’re unlikely to be able to achieve your goal here.

Reply to EASession(accessory:forProtocol:) always returns nil — MFI accessory iAP2
Hi Kevin, Thank you for the troubleshooting steps. To clarify the current state of the environment: Testing Environment: I am testing exclusively on a physical iOS device (iPhone [Model] running iOS [Version]); I am not using the simulator for these tests. Framework: The implementation is already built using UIKit. I am managing the accessory lifecycle within a standard UIViewController and AppDelegate structure. Integration Status: Despite being in a pure UIKit environment, I am still facing the issue where [mention the specific symptom, e.g., the accessory is not appearing in the picker / the session fails to open]. Since I have already ruled out SwiftUI lifecycle interference and simulator limitations, are there specific logging categories in Console.app or internal ExternalAccessory states you recommend I monitor to diagnose why the connection is failing?

App review process takes long time
Hello iOS Developer Community, I submitted my app for review on February 19, 2026, and as of today (March 3, 2026), its status in App Store Connect still shows “Waiting for Review.” I contacted Apple Developer Support regarding this delay and received the following automated response: “Thanks for submitting your support request. We’ve received your support request and will get back to you as soon as possible. Your case ID is 102831222355.” It has now been more than ten days without any further communication or status update. Could anyone advise on the appropriate next steps in this situation?

RoomCaptureView runs on the latest system with a serious bug causing errors
I am using RoomCaptureView for house scanning and modeling On the latest iOS 26, the following issues were encountered The program runs well on iOS 26 and below, but on iOS 26 and above, the probability of scene localization failure becomes abnormally high, and accurate indoor localization cannot be obtained. Additionally, the probability of using RoomBuilder to merge models is also high After compiling the program using xcode 26 or above, a necessary bug appeared when running it on iOS 26, RoomCaptureView is completely unable to run The error message is {RoomCaptureSession.

Massive CoreML latency spike on live AVFoundation camera feed vs. offline inference (CPU+ANE)
Hello, I’m experiencing a severe performance degradation when running CoreML models on a live AVFoundation video feed compared to offline or synthetic inference. This happens across multiple models I've converted (including SCI, RTMPose, and RTMW) and affects multiple devices. The Environment OS: macOS 26.3, iOS 26.3, iPadOS 26.3 Hardware: Mac14,6 (M2 Max), iPad Pro 11 M1, iPhone 13 mini Compute Units: cpuAndNeuralEngine The Numbers When testing my SCI_output_image_int8.mlpackage model, the inference timings are drastically different: Synthetic/Offline Inference: ~1.34 ms Live Camera Inference: ~15.96 ms Preprocessing is completely ruled out as the bottleneck. My profiling shows total preprocessing (nearest-neighbor resize + feature provider creation) takes only ~0.4 ms in camera mode. Furthermore, no frames are being dropped. What I've Tried I am building a latency-critical app and have implemented almost every recommended optimization to try and fix this, but the camera-feed penalty remains: Matche

Potential iOS26 regression on AASA file not download on app install
Original discussion pre iOS 26 Our app uses Auth0 with HTTPS callback, we've found the issue where AASA file is not ready immediately when app is initially launched, which is the exact issue from the above link. The issue seems mostly fixed on later versions on iOS 18, however, we are seeing some indications of a regression on iOS 26. Here's some measurement over the last week. | Platform | iOS 18 | iOS 26 | |---------------|----------|--------| | Adoption rate | 55% | 45% | | Issue seen | 1 | 5 | | Recover? | Yes | No | This only 1 iOS 18 instance was able to recover after 1 second after the first try, however, all iOS 26 instances were not able to recover in couple tens of seconds and less than 1 minute, the user eventually gave up. Is there a way to force app to update AASA file? Are there some iOS setting (like using a VPN) that could potentially downgrade the AASA fetch?

Reply to iOS26.4,appStoreReceiptURL获取票据延迟
I'm encountering the same issue as you; currently, I've implemented a 1.5-second delay. I hope Apple can resolve this soon. Recently, I tried upgrading to StoreKit 2, but on iOS 26.4, Transaction.updates does not return unfinished transactions upon launch, which is causing some problems.
