Hello, I want to use universal links in my application, for which I need to get the TeamID and BundleId, for apple-app-site-association file. Can you please tell me, do I have to buy an Apple Developer Account at the time of development to do this, or can I get it all for free at the time of development?

I would like to inquire about Apple's recommended best practices for iPhone thermal management. Specifically, what actions are developers expected to take to prevent the device from overheating? I am aware that we should subscribe to Thermal State Notifications and throttle performance accordingly—such as by reducing streaming quality or temporarily disabling active features. Beyond these measures, are there any other strategies you recommend to mitigate thermal issues and help the device cool down?

In iOS AP-mode onboarding for IOT devices, why does the iPhone sometimes stay stuck on the device Wi-Fi (no internet) and fail to route packets to the device’s local IP, even though SSID is correct? Sub-questions to include: • Is this an iOS Wi-Fi auto-join priority issue? • Can AP networks become “sticky” after multiple joins? • How does iOS choose the active routing interface when Wi-Fi has no gateway? • Why does the packet never reach the device even though NWPath shows WiFi = satisfied?

Device: iPhone 17 Series System: iOS 26.0.0 Wi-Fi: TKIP encryption protocol Question: Unable to join the network We have several products that are used by connecting to iPhone via Wi-Fi. Recently, many customers who have purchased the iPhone 17 series have reported that they are unable to connect to Wi-Fi. For Wi-Fi with TKIP encryption, after entering the password correctly to connect to the Wi-Fi, a pop-up appears stating "Unable to join the network.". Only Wi-Fi with WPA2-AES can be used normally. Before that, during the iPhone 11 era or even earlier, the TKIP encryption method was in normal use. However, the new iPhone models were incompatible with it, which obviously caused great inconvenience. I hope the engineers can fix this issue to support Wi-Fi with older encryption protocols.

We are facing an issue: push notifications are not being received. We are using the Marketing Cloud SDK for push notifications. On install, the app correctly registers for push notifications. We pass the required information to Marketing Cloud — for example, contact key, token, etc. Marketing Cloud also confirms that the configuration is set up, and we have tried sending push notifications with proper delivery settings. The issue is that after some time, the device gets automatically opted out in the Marketing Cloud portal. When we consulted their team, they said this is caused by the “DeviceTokenNotForTopic” error received from APNs. I have verified the certificates and bundle ID from my end — everything looks correct. Device: iPhone 15, iPhone 17 iOS: 18.7.2, 26.1

Hello, maybe anyone know anything about HCE (Host card emulation) feature on iOS? As far as I read, it's not possible to achieve this functionality on iOS, but maybe there are plans to implement that? Or maybe it's clear that it wont be allowed to be used at all? Thanks:)

My device with Device ID (00008130-001E35840483401C) is stuck in Processing state and cannot be activated. Please refresh or delete it.

I am making an iOS step counting app and I have included a widget in the design. I would like to get the widget to pull data from the main app to display step count etc so I created a bundle id for the widget and have been trying to use a group id to link them together. The group capabilities for both seem to be set up/enabled properly with the same App Groups id, but I've been getting an error in xcode which says, " 'Provisioning Profile: "BUNDLE_ID" doesn't include the com.apple.developer.security.application-groups entitlement.' Try Again But the identifiers do have the App Group id enabled. I have tried automatic signing, manual signing with generated profiles, unchecking and rechecking auto-signing, removing and re-adding the group capability. Creating a new bundle id from scratch, creating a new group id from scratch. Always I get the error. I've really pulled my hair out troubleshooting this and would appreciate support. I'm happy to answer and questions or share details. Thank you.

When will Apple mobile phones support some of the optional features of Bluetooth 5... specifically Extended Advertising and LE Coded PHY? There are many applications that benefit from having this capability in the mobile phone.

Hi Is there a way to create a dynamic app clip card experience? I have advanced app clip experiences set up and working fine already and but I am looking to provider a more dynamic experience. For example, my invocation url now is https://mycompany.com/profile/<profile_slug>, this URL shows the app clip card with the title, subheading, and cover image as configured in app store connect which is right. But I would like to show a different title, subheading, and cover image based on the <profile_slug> in the invocation URL. Like we can show the name as the title, job title as the subheading, and profile's banner image as the cover image for the app clip It seems like this is possible as I have seen one company do this for their product. Apple has no mention for such a thing in their documentation from what I have seen. Any help would be appreciated. Thanks

Hi, does anyone know how to enable creating or configuring Near NFC Reader in SwiftUI? I've already added the capability, the permissions in info.plist, the entitlement, and the SwiftUI code, but without success.

Hello All, I’m a mobile-app developer working with iOS 26+ and I’m using BGContinuedProcessingTask to perform background work. My app’s workflow includes the following business logic: Loading images via PHImageRequest. Using a CLIP model to extract image embeddings. Using an .mlmodel-based model to further process those embeddings. For both model inferences I set computeUnits = .cpuAndNeuralEngine. When the app is moved to the background, I observe that the same workload(all three workload) becomes on average 4-5× slower than when the app is in the foreground. In an attempt to diagnose the slowdown, I tried to profile with Xcode Instruments, but since a debugger was attached, the performance in background appeared nearly identical to foreground. Even when I detached the debugger, the measured system resource metrics (process CPU usage, system CPU usage, memory, QoS class, thermal state) showed no meaningful difference. Below are some of the metrics I captured: Process CPU: 177% (Foreground) → 153% (Background) → ~-24.1% Still >1.5 cores of work. System CPU: 56.1% → 38.4% → ~-17.7% Process Memory: 244.8 MB → 218.1 MB QoS Class: userInitiated in both cases Thermal State: nominal in both cases Given these results, I’m finding it hard to pinpoint why the overall latency is so much worse when the app is backgrounded, even though the obvious metrics show little variation. I suspect the cause may involve P-core vs E-core scheduling, or internal hardware throttling/limit of Neural Engine usage, but I cannot find clear documentation or logging to confirm this. My question is: Does anyone know why a CPU (and Neural Engine)-intensive job like this would slow down so dramatically when using BGContinuedProcessingTask in the background on iOS 26+, despite apparent similar resource-usage metrics? Are there internal iOS scheduling/hardware-allocation behaviors (e.g., falling back to lower-performing cores when backgrounded) that might explain this? Any pointers to Apple technical notes, system logs, or instrumentation I might use to detect which cores or compute units are being used would be greatly appreciated. Thank you for your time and any guidance you can provide. Best regards,

My project uses the UINavigationController's largeTitle on the latest iOS 26.1, but I found that when I set the backgroundColor, the navigation bar's largeTitle disappeared after switching between normal and large titles. I checked the latest documentation and consulted AI, but I have not found any good solutions. For the demo project, please refer to FB20986869

I’m experiencing an issue after building the project with Xcode 26.1.1. In my code, I have a UICollectionView that contains multiple cells, and each cell has a slider. When I move a slider in one cell, sliders in other cells also move. This issue does not occur in Xcode 16.4 – it works perfectly there. If anyone has a solution or knows if this is related to Xcode 26 changes, please let me know. Thanks!

Description of the current implementation: A section, UIView, has been added to UITableView. This section is a UICollectionView that displays an array of images. Each UICollectionViewCell is an image displayed via a UIImageView. Issue: When UITableView is scrolled vertically, the section with the image collection flickers. Attempts made to solve the problem: if #available(iOS 26.0, *) { tableView.bottomEdgeEffect.isHidden = true tableView.topEdgeEffect.isHidden = true tableView.leftEdgeEffect.isHidden = true tableView.rightEdgeEffect.isHidden = true } else { // Fallback on earlier versions } This helped with a similar issue. I tried it on UITableView and UICollectionView, but it didn't work.

Hi everyone, I’ve been stuck on an issue with iOS Universal Links for about a week and could really use some help. The problem When tapping a Universal Link on iOS, my Flutter app opens correctly (desired behavior) — but immediately afterward, Safari opens the same link in the browser. So both the app and the browser open. This only happens on iOS. On Android everything works as expected. What works If the link is simply the domain, like: https://mydomain.com …then the app opens without triggering the browser afterward. This is the correct behavior. What doesn’t work If the link includes a path or parameters, like: https://mydomain.com/path https://mydomain.com/path?param=value …then the app opens, and then the browser opens immediately after. What I’ve tried Verified my AASA file using Branch’s validator: https://branch.io/resources/aasa-validator/ → The AASA file is valid. Universal Links do open the correct screen inside the app — the issue is the unwanted second step (Safari opening). Behavior is consistent across different iOS devices. Extra details Using Flutter. Universal Links set up with the standard configuration (associatedDomains, AASA hosted at /.well-known/apple-app-site-association, etc.). Question Has anyone encountered this issue where Universal Links with paths/params open the app and then open Safari? What could cause iOS to trigger the browser fallback even when the AASA file is valid and the app handles the link correctly? Any insights, debugging tips, or known edge cases would be incredibly appreciated!

For what iPhone and iPad models under iOS 26 SpeechTranscriber.isAvailable is true

After it updated i am facing issue in phone logs. i can not see the unknown called misscall on logs. Everytime its say no recen calls

My app has been published by 2 months now I still I cant get Universal Links to work. I checked a lot of docs as well as videos about setting up universal links. Everyone with clear steps: Add the well-known json file to the server. Already validated by AASA web validator. Add the Associated domain on project capabilities, with the Web page root only. Eg: applinks:example:com. Install the app and trying clicking a link from notepad. Or instead make a long press to deploy contextual menu to see if my app is on the selectable options to open the link. My app is not been open in any of my attempts and the console always trying to use safari. I had a couple of screenshots of my testing. I really need help with this.

When my Bluetooth peripheral device has both HID and MIDI services, the iOS Bluetooth host repeatedly sends different "Control Opcode: LL_CONNECTION_UPDATE_IND" to the peripheral, updating approximately every 100ms. The Bluetooth peripheral cannot handle such high-frequency update requests and typically disconnects with an error 0x28. My Bluetooth device uses the NRF52832 chip, and I have communicated with NORDIC and replicated this issue. This problem only occurs on iOS 26; it does not happen on earlier versions. I think it might be caused by the HID service in iOS requesting faster connection parameters for low latency, which then gets erroneously reverted for an unknown reason, leading to repeated competition and entering into a deadlock. Here is the communication record with NORDIC: https://devzone.nordicsemi.com/f/nordic-q-a/124994/ios-26-bluetooth-disconnect-issues This is the screenshot captured using the Bluetooth sniffer:
