HKObserverQuery stops delivering updates in background on watchOS 26
Hello, I’m building a health-related app for both watchOS and iOS, which needs to monitor certain health data (e.g., heart rate, active energy). Before updating to watchOS 26, the queries worked reliably without any issues. However, after adapting to watchOS 26, some users have reported that health data updates stop being delivered. What I’ve observed: HKObserverQuery with enableBackgroundDelivery is set up normally. On WatchOS 26, the query sometimes stops delivering updates entirely after a certain point, and once an update is missed, it may stop delivering further updates completely. Restarting the Apple Watch temporarily restores delivery, but the problem reoccurs after some time. This makes background health data monitoring unreliable for my app. Here’s a simplified version of the code we are using: guard let heartType = HKObjectType.quantityType(forIdentifier: .heartRate) else { return } let query = HKObserverQuery(sampleType: heartType, predicate: nil) { query, completionHandler, error in if l

Warning "Public import of 'CoreData' was not used in public declarations or inlinable code"
Hello, In my App.xcdatamodeld I have an entity called File. When I am building the project with Xcode, file FileEntity+CoreDataProperties.swift is generated. After upgrading Xcode to version 26.0 (17A324), I am getting the warning: Public import of 'CoreData' was not used in public declarations or inlinable code Any idea how to get rid of this warning since it's a generated file and I can't see any option to change it?

Reply to Allow "Browser" to find devices on local networks
Ah, yes, Chrom{e,ium}. There’s definitely something weird going on there, but I’ve yet to see a definitive answer as to what it is. It certainly isn’t as simple as ‘local network using build UUIDs for everything’, because if that were the case then all apps would lose their local network privacy privilege after every update. However, it’s also true that the network subsystem uses build UUIDs in ways that I’m not super happy with. [quote='859253022, poluyanov, /thread/800879?answerId=859253022#859253022, /profile/poluyanov'] a new …/Versions/A.B.C.D folder with the updated version is added [/quote] Wha? You’re relying on framework versions? That is… well… not what I’d do. That’s not been best practice for a long time, and our docs are now clear about that. Is the local network call being made by the process running your app’s main executable? Or by, perhaps, a helper tool embedded in this framework? Is this issue causing grief for your users? Or only during development? After reproducing the

Reply to Too many mach ports?
We have a customer reporting a bunch of problems with our (Transparent Proxy Provider-based) suite. Looking at a sysdiagnose, I see that our GUI applet was killed: Termination Reason: Namespace PORT_SPACE, Code 14123288431434181290 (Limit 305834 ports) Exceeded system-wide per-process Port Limit Looking at the top.txt file from it, I see that it has 193,086 ports -- compared to about ~250 on one of my test systems. So, let me just say that crashing like this is the BEST possible outcome for an issue like this. Mach port communication is so fundamental to the system’s function that Mach port leaks can basically break anything in your app. Crashing is the good failure here, as that is much easier to investigate than hangs randomly in different places for no apparent reason. Has anyone run into this? Yes, I've seen Mach port leaks before. Historically, they were a consistent long-standing source of bugs through the entire system. Indeed, one of the major reasons XPC exists was to provide a slightly higher-level

How to reliably link a new build to newly-created IAP? After submitting, selected IAP “disappear” from the submission
Hi everyone, I’m trying to submit my first release with In-App Purchases, but I can’t keep the IAP attached to the submission. Status: Not published yet (first release) Version: 5.0.0 (multiple builds: (7), (8), etc.) What happens I upload a new build and select it for version 5.0.0. I go to Add for Review and select my newly created IAP (auto-renewable subscriptions). I submit the version. When I re-open the submission details, the IAP section is empty (they no longer appear as “Included in this submission”). The result is a double failure: App rejection (Guideline 2.1 – “IAP not found in the submitted binary”). Each IAP is also rejected for lack of a binary in its review context. It looks like the IAP and the build keep getting detached from each other after I submit. Since this is my first version, I’ve tried changing builds and even editing version metadata, but it still feels like I’m just “editing the first version” rather than creating a fresh link between this binar

How to debug apps with Xcode only using USB?
Hello. I am using Xcode 26.0 (17A324) with an iPhone 13 mini with iOS 26.0 (23A341). Due the network policies where my computer is at this moment, I am not able to prepare this iPhone to debug applications with Xcode over WiFi. There is no way to connect my computer to this iPhone over Wifi, just using the USB cable. My question is: how to debug applications in this situation, only using the USB cable? Every time I try to prepare this iPhone to be a available device to Xcode I received this error: Browsing on the local area network for iPhone (2), which has previously reported preparation errors. Ensure the device is unlocked and attached with a cable or associated with the same local area network as this Mac. The device must be opted into Developer Mode to connect wirelessly.

RealityKit captureHighResolutionFrame from session is broken on iOS26?
A bit of background on what our app is doing: We have a RealityKit ARView session running. During this period we place objects in RealityKit. At some point user can take photo and we use session.captureHighResolutionFrame to capture a frame. We then use captured frame and frame.camera.projectPoint to project my objects back to 2D Issue we found is that on devices that have iOS26, first photo user takes and the first frame received from session.captureHighResolutionFrame gives incorrect CGPoint for frame.camera.projectPoint. If user takes the second photo with the same camera phostion, second frame received from session.captureHighResolutionFrame gives correct CGPoint for frame.camera.projectPoint I notices some difference between first and subsequent frames that i believe is corresponding with the issue. Yaw value of camera (frame.camera.eulerAngles.y) on first frame is not correct ( inconsistent with any subsequent frame) I also created a small example app and i followed Building an Immersive Experi

Reply to How to restore macOS routing table after VPN crash or routing changes?
Thanks for your response Quinn @DTS Engineer . You’re correct, my VPN isn’t based on a Network Extension provider, but I do use a Transparent Proxy to divert some traffic outside the tunnel. Based on your suggestion, I’m considering building entirely on the NetworkExtension framework with two providers: NETransparentProxyProvider – intercepts app sockets so I can decide what to bypass. NEPacketTunnelProvider – encapsulates and encrypts the rest according to my VPN protocol. My goal is that each TCP/UDP socket first reaches the Transparent Proxy callback, and if diverted to the tunnel, then it flows the data through the Packet Tunnel provider for encapsulation before hitting the physical adapter. Is this the expected pipeline when both providers are active ? Thanks !

App icon not showing in TestFlight and App Store Connect, but visible on device
Hi everyone, we are currently facing an issue with one of our apps regarding the new icon requirements in iOS 26. • We created the app icon using Apple’s Icon Composer. • On the device, everything works perfectly: the app icon is shown on the home screen, and it can also be customized with the new iOS 26 features (colors, transparency, etc.). • However, in TestFlight the app icon is not displayed at all (in the TestFlight app on the device). • In App Store Connect, the icon is also not shown in the overview for the app. Interestingly, within the list of TestFlight builds in App Store Connect the icon is visible. What we have tried so far: • Created an archive and manually uploaded it to App Store Connect → no icon in TestFlight. • Took the working Icon Composer asset from another app target where everything works correctly, deleted the old one in this project, and copied the working asset into the problematic target. → Same behavior: visible on the device, but still missing in TestFlight and App Stor

Any strategies for leveraging review responses to improve ASO results?
I’ve been building iOS apps since 2011 and have worked on hundreds along the way. Recently, I started a series on App Store Optimization (ASO) to share tips, strategies, and lessons learned. In this first post, I dive into how responding to customer reviews can directly influence ASO performance and App Store ranking - covering timing, response style, and best practices to turn negative reviews into positive ones.

Reply to Clarification and help with the certificate.
[quote='859098022, kallookoo, /thread/801301?answerId=859098022#859098022, /profile/kallookoo'] you can't manage certificates without being a paying member. [/quote] Correct. Usually this isn’t a problem because Xcode’s automatic code signing takes care of everything for you. But it certainly does make it harder to investigate weird issues. Are you actually having problems running your app? Or are you solely concerned with the presence of this extra certificate that you can’t delete? If it’s the latter, I think that this’ll fix itself. Eventually this certificate will expire and thence disappear from the list. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = eskimo + 1 + @ + apple.com
