Like any good developer, I try to add tests where I can. The AgeRangeService.AgeRange type does not provide an initializer. I know the routine, create an interface or a simple struct that I control and use that instead. Thanks to extensive time with frameworks like Core Bluetooth or Core Location, this is a well understood practice (looking at you CBPeripheral...). Great I'll make my own 'AgeRange' struct. Make it Hashable, make it Sendable, use the framework types as properties. Scratch that, most of the properties on AgeRangeService.AgeRange type are not Sendable and many are also not Hashable. This is proving to be challenging. I hope to open source my little Swift Package wrapper library for DeclaredAgeRange which will add types with full Hashable and Sendable conformance. I hope Apple updates the API and makes this obsolete. I don't see why these simple types can't be Hashable and Sendable. They're structs, enums, and OptionSets (structs). FB20959748 - DeclaredAgeRange: DeclaredAgeRangeAction is not sendable causing main actor compile errors with default isolation settings FB20960560 - DeclaredAgeRange: AgeRangeService.AgeRangeDeclaration is not sendable as expected FB20960574 - DeclaredAgeRange: AgeRangeService.ParentalControls is not sendable as expected FB20960590 - DeclaredAgeRange: AgeRangeService.ParentalControls is not hashable as expected On the note of the library and using the types as-is, there are some issues using the new cases in AgeRangeDeclaration and the isEligibelForAgeFeatures property. I started another thread over here: https://developer.apple.com/forums/thread/808144

I'm making a wrapper library to abstract away some of the 'missing platform support' of DeclaredAgeRange until hopefully it expands to additional platforms. When I'm trying to fully enumerate all of the cases of AgeRangeDeclaration, which they all state available starting 26.0 (mysteriously added in Xcode 26.2 beta), the app crashes due to a missing symbol at launch time. This happens both for Xcode 26.1, 26.2 beta 2, and matching Xcode Cloud builds. So I've isolated it beyond "doesn't work on my machine". I just made a handful of crashes and attached a sysdiagnose to a fresh feedback. FB21121092 - DeclaredAgeRange: Eligibility property and new declaration cases unavailable on iOS 26.1 device contradicting documentation - causes runtime symbol not found crash If anyone is curious what these crashes look like I've attached the DiagnosticPayload.jsonRepresentation() generated from one of my favorite frameworks, MetricKit. Very clearly articulated in the diagnostic metadata you can see the symbol not found. "diagnosticMetaData" : { "platformArchitecture" : "arm64e", "terminationReason" : "Symbol not found: _$s16DeclaredAgeRange0bC7ServiceV0bC11DeclarationO14paymentCheckedyA2EmFWC\nReferenced from: <1894EDCB-3263-3604-8938-97D465FF3720> \/Volumes\/VOLUME\/*\/PerformanceOrganizer.app\/PerformanceOrganizer\nExpected in: <B8FD2C23-0CC9-3D94-902D-875900307A7A> \/System\/Library\/Frameworks\/DeclaredAgeRange.framework\/DeclaredAgeRange", "exceptionType" : 10, "appBuildVersion" : "745", "isTestFlightApp" : true, "osVersion" : "iPhone OS 26.1 (23B85)", "bundleIdentifier" : "dev.twincitiesapp.performanceorganizer", "deviceType" : "iPhone18,1", "exceptionCode" : 0, "signal" : 6, "regionFormat" : "US", "appVersion" : "2.0.0", "pid" : 22987, "lowPowerModeEnabled" : false } DiagnosticPayload.json This is the offending code in a type I control and make available on other platforms but leave unused. extension AgeRangeDeclaration { // A factory or initializer that takes the AgeRangeService.AgeRangeDeclaration and maps to the common AgeRangeDeclaration type public init?(platform value: AgeRangeService.AgeRangeDeclaration?) { guard let value else { return nil } switch value { // Xcode 26.1 visible cases case .selfDeclared: self = .selfDeclared case .guardianDeclared: self = .guardianDeclared // Xcode 26.2 visible cases // This is the first culprit, all of the following symbols would crash, this is just the first case .checkedByOtherMethod: self = .checkedByOtherMethod case .guardianCheckedByOtherMethod: self = .guardianCheckedByOtherMethod case .governmentIDChecked: self = .governmentIDChecked case .guardianGovernmentIDChecked: self = .guardianGovernmentIDChecked case .paymentChecked: self = .paymentChecked case .guardianPaymentChecked: self = .guardianPaymentChecked @unknown default: // Apple added new cases in Xcode 26.2 betas that were available in iOS 26.0, // so it is probable that this could happen again.

As a side note, thank you for this property, it will let me check what states I need to perform extra checks for in a clean way, I just will need it to now not crash my app on 26.0 and 26.1 runtime devices. :) Edit: DTS did confirm on a comment I had in another thread that this is a bug. Now just to wait for an Xcode beta update. https://developer.apple.com/forums/thread/807906?answerId=867205022#867205022 In any case, this is a great example of how MetricKit totally rocks capturing things other off the shelf crash tools might not have a chance to get. I did have to roll back my TestFlight to an earlier build, but MetricKit was there to send me the previous crashes as soon as the app could launch. Thanks MetricKit team!

I've been writing about the DeclaredAgeRange a bit on LinkedIn and now it is time to take to the developer forums. In my efforts to prepare my apps for new local requirements, I've run across some rough edges. The DeclaredAgeRange API is missing on several platforms, and extension types. First and foremost, watchOS. An Apple Watch is a clear single user platform and for standalone apps, the DeclaredAgeRange being absent is felt by developers. FB20954931 - DeclaredAgeRange: Framework not available on watchOS making compliance a challenge for watchOS standalone apps In the same vein of thinking, while users on Apple Vision Pro are far fewer numbers than Apple Watch, it is also a miss. The tricky part would be testing on the simulator. So far I haven't gotten the simulator and sandbox testing to work and give real values across any platform. I don't think an Apple Store will let me try my app out via TestFlight on their devices and they're still too expensive to reasonably buy for most developers. Too bad Feedbacks are not a currency that developers can trade in for gear. FB20955020 - DeclaredAgeRange: Framework not available on visionOS making compliance a challenge for visionOS apps I'll recognize that the user model is different on tvOS, and that as a user while I have family group setup, I don't have any children on the account. I have to imagine that child accounts on an Apple TV exist and would be able to account for the sharing of age ranges to apps. Yes, the user could just switch profiles, but, app developers could still integrate the age range into their apps. Maybe it needs more robust system level support but here is the feedback just the same. FB20955029 - DeclaredAgeRange: Framework not available on tvOS making compliance a challenge on tvOS apps And finally, let's not forget about App Clips. While the App Clips might not be 'downloaded' from App Store itself, it is powered by App Store technologies to an extent. I'd rather not bifurcate my code more than it already is for the shared code between my apps and app clips. Rounding out platform support to App Clips, since it is iOS, would close the loop. FB20954846 - DeclaredAgeRange / App Clips: Add support for DeclaredAgeRange framework for App Clip targets - capability exist, Xcode cannot generate entitlement for it Oh wait, actually, not quite. To fully close the loop, make the DeclaredAgeRange work fully on macCatalyst. The documentation says it is compatible, but from my experiments trying to get it to even compile when targeting macCatalyst apps simply doesn't build. FB21117325 - DeclaredAgeRange: API documentation states available on mac catalyst - but fails to compile in Xcode 26.2

I tried to use the Connect app this morning and it said a developer account was needed. On the contrary, I am the account holder, which is what the CTA to fix the issue in the app stated to ask for access from. Then I tried to sign in directly on the website and it also didn't respond there. FB19906255 - App Store Connect: Connect app not responding and neither is App Store Connect portal Aug 26, 8:15 AM Central Posting in case others run into this, I have not seen the developer status page report anything yet: https://developer.apple.com/system-status/

Has anyone had success using the HKWorkoutRouteBuilder in conjunction with the new iOS support for HKLiveWorkoutBuilder? I was running my watchOS code that worked now brought over to iOS and when I call insertRouteData the function never returns. This happens for both the legacy and closure based block patterns. private var workoutSession: HKWorkoutSession? private var workoutBuilder: HKLiveWorkoutBuilder? private var serviceSession: CLServiceSession? private var workoutRouteBuilder: HKWorkoutRouteBuilder? private func startRouteBuilder() { Task { @MainActor in self.serviceSession = CLServiceSession(authorization: .whenInUse) self.workoutRouteBuilder = self.workoutBuilder?.seriesBuilder(for: .workoutRoute()) as? HKWorkoutRouteBuilder self.locationUpdateTask = Task { do { for try await update in CLLocationUpdate.liveUpdates(.fitness) { if let location = update.location { self.logger.notice(#function, metadata: [ "location": .stringConvertible(location) ]) try await self.workoutRouteBuilder?.insertRouteData([location]) self.logger.notice("Added location") } } } catch { self.logger.error(#function, metadata: [ "error": .stringConvertible(error.localizedDescription) ]) } } } } I did also try CLLocationManager API with delegate which is what my current watch code uses (a bit old). Same issue. Here is what I've found so far: If the workout session is not running, and if the builder hasn't started collection yet, inserting route data works just fine I've tried different swift language modes, flipped from main actor to non isolated project settings (Xcode 26) Modified Apple's sample code and added location route building to that and reproduced the error, modified sample attached to feedback This issue was identified against Xcode 26 beta 2 and iPhone 16 Pro simulator. Works as expected on my iPhone 13 Pro beta 2. FB18603581 - HealthKit: HKWorkoutRouteBuilder insert call within CLLocationUpdate task never returns

I am very happy to see that HealthKit with OS26 is bringing HKLiveWorkoutDataSource to iOS and iPadOS. I have been replicating a similar type for the last several years for users that only have an iPhone. I did notice that the data types that the different platform data sources collect automatically is different. That makes sense if you think exclusively about what the device can actually capture. Bluetooth HRM is the only Bluetooth SIG profile that is out-of-the-box supported for Apple Health on iOS and iPadOS (right?). Whereas watchOS 10 got all of the cycling sensors (woohoo!). It would be great if the types to collect were the same across platforms even if the device couldn't collect the data now, because then in the future when / if new sensor support is added, it will be transparent to developers. Fantastic. Easier life as an indie / third party developer. At least that is the idea. And yes, I know I can also write Core Bluetooth code and roll my own SIG implementation for the cycling profiles, but Apple already has this code in one os, 'just copy it, it will be easy'. I know that isn't the reality especially against the new ASK framework, but one can hope and dream right? Imagine how many more apps would contribute that data if it was supported out of the box. An alternative, GitHub is a great place for Apple to share their Core Bluetooth implementation of the SIG profiles :). Just another thought. Here are some feedbacks related to this: FB17931751 - HealthKit: Add built-in support for cycling sensors on iOS and iPadOS - copy paste the code from watchOS. It will be easy they said (June 2025) FB12323089 - CoreBluetooth / Health / Bluetooth Settings: Add support for cycling sensors announced in watchOS 10 to iOS and iPadOS 17 (June 2023) FB14311218 - HealthKit: Expected outdoor cycling to include .cyclingSpeed quantity type as a default HKLiveWorkoutDataSource type to collect (July 2024) FB14978701 - Bluetooth / HealthKit / Fitness: Expose information about the user specified for Apple Watch paired Cycing Speed Sensor like isConnected and wheelCircumference values (August 2024) FB18402258 - HealthKit: HKLiveWorkoutDataSource should collect same types on iOS and watchOS even if device cannot produce data today (June 2025) FB14236080 - Developer Documentation / HealthKit: Update documentation for HKLiveWorkoutDataSource typesToCollect for which sample types are automatically collected by watchOS 10 and 11 (July 2024) Tangentially related: FB10281304 - HealthKit: Add HKActivityTypes canoeBikeRun and kayakBikeRun (June 2022) FB10281349 - HealthKit: Add HKActivityType walkCanoeWalk and walkKayakWalk (June 2022) FB7807993 - Add HKQuantityTypeIdentifier.paddleDistance for canoeing, kayaking, etc type workouts (June 2020) FB12508654 - HealthKit / Settings / Bluetooth / Workouts: Cycling sensor support doesn't allow for 'bike selection' in use case of multiple bikes and multiple sensors (borrow a bike to ride together) - production usability issue (July 2023)

I'm running into an undocumented error coming back from CloudKit operations. Specifically, I'm attempting to save new records via CKModifyRecordsOperation. I'm receiving this error for each of the records in the perRecordSaveBlock callback: &lt;CKError 0x3018ac3c0: "Internal Error" (1/3001); "MMCSEngineCreate failed"&gt; Is anyone else facing this error? It has been happening for several days and I'm finally getting around to reproduction with the Console app and logs. I have 16 records on my device locally that each one gets this error back. FB16547732 - CloudKit: CKModifyRecordsOperation saving new records results in Error &lt;CKError 0x3018ac1e0: "Internal Error" (1/3001); "MMCSEngineCreate failed"&gt;

I created a new index on two record types on Oct 12th. I still cannot query the records using the new queryable index on records that were created before that date. There is no indication in the schema history that the reindexing has started, completed, failed, or still in progress. What is the expectation for new indices being applied to existing records? Well over a week seems unacceptable for a database that has maybe 5000 records across a few record types. When I query my data using an old index and an old record field, I get hundreds of matching results so I know the data is there. FB15554144 - CloudKit / CloudKit Console: PRODUCTION ISSUE - Query against index created two weeks ago not returning all data as expected

I'm a big fan of MetricKit. I decided to see how my apps are performing with iOS 18 and well, I'm not getting any metric payloads from those devices. Metric payloads received from my test devices adopting iOS 18 has pretty much bottomed out to zero. Is anyone getting MetricKit MXMetricPayloads from iOS 18 devices? FB15461298 - MetricKit: Production issue / regression with iOS 18 - Significant dropout or metric payloads being generated since 18.0 - nearly no reports To demonstrate the issue, I decided to graph the metric payloads my infrastructure receives for all of my apps across all of my devices over the last 16 months starting with WWDC23 timeframe. This data is grouped by count per month. A trend can easily be seen starting in June 2024 where I started to adopt iOS 18 betas. Zooming in since WWDC24, grouped by week, it is much easier to see the decline. Note, the second screenshot shows data collected from Xcode builds, TestFlight, and App Store. The last data point from today was a manual creation from Xcode's Debug window, so at least that triggering mechanism works and I can confirm all of my code to upload off device works as expected. On the bright side, I guess I will ship this 'payload received over time' feature in my MetricKit payload analyzer app with a scrolling window and group by features that make up these screenshots.

Apple is using the RPE scale for workout effort scores. This stands for the Rate of Perceived Exertion. They're specifically using the CR-10 scale, at least from what I can tell by saving values to HealthKit. They only accept value between 0 and 10. Has anyone been able to find a scientific or academic paper on how they have chosen their different effort breakouts? Right from the Fitness app on iPhone and Activity app on Apple Watch: 1-3 Easy 4-6 Moderate 7-8 Hard 9-10 All Out There is zero documentation on these new types, which makes it difficult for workout recording apps to properly and appropriately save this new data type. Sure, we can use the Apple apps as a reference, but since there isn't a built-in Apple SwiftUI sheet to present this data, and no references to academia to point our users to, our solutions would just look the same. FB15315876 - Documentation / HealthKit: Publish documentation about .workoutEffortScore and .estimatedWorkoutEffortScore FB15316109 - Documentation / HealthKit: Add documentation to .estimatedWorkoutEffortScore and .workoutEffortScore that you can't save those samples via the save API and that they must be related and let that API save the sample FB15316251 - Documentation / HealthKit: Add documentation for acceptible values of .estimatedWorkoutEffortScore and .workoutEffortScore - don't rely on a runtime error! Apple missed making an enum for all third party developers this year.

I am encountering issues on my device running iOS 18 that fetching heart rate samples associated to a given workout is very slow. Like 10+ seconds slow. This is unacceptable and unexpected. In producing a video to attach to a feedback, I also observed that Apple Health app displays incorrect information if a workout effort score is associated to a workout. In this image, you can see the Health app bug: Total Resting Energy != Estimated Workout Effort Score Here is the same workout after I delete the workout effort score using the Apple Health app: Can anyone else see if attempting to view 'heart rate' data within the workout summary in Apple Health is unbearably slow if that workout also has an effort score associated? My steps: Record workout (Apple Activity app on watchOS) Associate effort score View the workout on Apple Health (iOS) Attempt to view it's heart rate samples Observe very slow loading times Observe the incorrect cell label and value and disappearance of resting energy cell data Remove/disassociate the effort score from the workout by tapping the workout effort row, and swipe to delete the value. Navigate back, navigate back, and then go into the workout detail again At this time the UI fixes itself, but the loading of heart rate data is still super slow FB15269657 - HealthKit: Sample query to fetch heart rate samples associated to a workout is taking over 10 seconds - computing 'time in heart rate zone' FB15278790 - Health: Workout summary 'Total Resting Energy' label has value of 'Estimated Workout Effort Score' for a value, pushed view shows empty

I noticed last night that workouts I have been recording on my main carry device running 17.6.x have not been syncing to my beta devices running iOS 18 RC, iPadOS 18 RC and watchOS 11 RC. All devices are using the same Apple Account and I have iCloud enabled for Health data. The iPad running the RC has the syncing enabled in Profile. Is anyone else experiencing health data not propagating to the 18.x devices? Some of data exists on all devices but not all. For good measure I left the device unlocked on the health app last night for a long period of time to let it do its thing. This morning the data still hadn't propagated. I disabled and reenabled the synchronization on my iPad having chosen to delete all samples when disabling it. Hopefully all of my data dating back to the first Apple Watch in 2014 restores. FWIW my data set according to iCloud settings my health dataset is just shy of 650 MB. FB15102443 - Health / HealthKit: Workouts, activity rings, sample data, and more not syncing via iCloud to 18 RC device

I archived and uploaded a build with Xcode 16 RC earlier today since it wasn't available in Xcode Cloud at that moment. The upload was successful. Since then, Xcode Cloud was updated with Xcode 16 RC and I can build and deploy to TestFlight and App Store Connect that way too. Now, upon submitting my app to App Review, the binary is being rejected as invalid due to unsupported version of Xcode. Rejections Sept 9th at 11:28 PM Central and Sept 10th 12:37 AM. Here is the error message I received via email: ITMS-90111: Unsupported SDK or Xcode version - App submissions must use the latest Xcode and SDK Release Candidates (RC). For details on currently supported versions, visit: https://developer.apple.com/news/releases. Upon visiting the site, you can see a developer news article stating that App Review is now accepting builds created from Xcode 16 RC. I assume this is just the system going through upgrades and the whole system isn't updated yet. Is anyone else having issues submitting Xcode 16 RC builds to App Review? Or the inverse, has anyone had success yet? Submission ID cf4e80cf-1629-4267-8604-8c3c161a0051 Same content just for added visibility: FB15088221

Finally at last Apple Health supports saving .distancePaddleSports, .distanceCrossCountrySkiing, .distanceRowing, .distanceSkatingSports, and much more. The backstory. In the land of 10,000 lakes, there hasn't been a way to save 'canoe' or 'kayak' distance and I've been asking for it for years. Thank you health team for adding it this year! FB7807993 - Add HKQuantityTypeIdentifier.paddleDistance for canoeing, kayaking, etc type workouts (June 2020) Prior we could just save the totalDistance to a workout, but since the HKWorkout initializers were deprecated we no longer have a supported way to save these distances in our workouts. The iOS 18 / watchOS 11 introduction addresses this. If you want to know more why you can't do this in earlier versions you can check these feedback titles: FB10281482 - HealthKit: Deprecation of totalDistance on a workout session of paddleSports breaks apps that used that to save distance to the workout because there is no "paddleDistance" type available to save as sample data (June 2022) FB12402974 - HealthKit: Deprecation of HKWorkout completely breaks support for third party fitness apps from saving non-standard workout distance (June 2023) Great, so there is new support that solves all of these requests and issues for the new version of the OSes. However, the downside is now that there is not much for documentation. Unlike the .runningSpeed and .runningPower introduced in iOS 16 / watchOS 9, none of the new iOS 18 / watchOS 11 types have documentation, at all. To some degree this is understandable, but types from last year still remain undocumented too. Without this information for the data types introduced in both iOS 17/18 and watchOS 10/11 it makes building and integrating with these new types difficult to say the least. We can't make assumptions about anything. Can we get a documentation update for new (and existing) quantity types for when Apple Watch will automatically generate samples? FB14236080 - Developer Documentation / HealthKit: Update documentation for HKLiveWorkoutDataSource typesToCollect for which sample types are automatically collected by watchOS 10 and 11 (July 2024) FB14942555 - HealthKit / Documentation: App Update Release Issue - HKQuantityTypeIdentifiers are missing documentation describing when the system automatically adds data (today) I know that the behavior has changed from release to release for some of these types, so documentation would be based on OS version. If you didn't catch it, watchOS 11 will now associate .cyclingSpeed for cycling workouts both indoor and outdoor. FB12458548 - Fitness: Connected cycling speed sensor did not save samples to health via cycling workout (June 2023 - received reply that only saved for indoor cycling, but not documented otherwise) FB14311218 - HealthKit: Expected outdoor cycling to include .cyclingSpeed quantity type as a default HKLiveWorkoutDataSource type to collect (July 2024) To the other third party fitness apps out there, how are you managing the knowledge of which devices collect which data types on which versions of the OS? Sure, we could look at the HKLiveWorkoutDatSource and inspect the typesToCollect property across a bunch of devices, but again that is trial by error not 'as documented'. Is the behavior of simulators guaranteed to match the behavior of real devices? Maybe, but also maybe not. Fingers crossed for a nice documentation update to spell out all of the behavioral details. Apple folks / DTS, many of the above feedbacks are addressed and I plan to update or close them after the releases this fall. Some are still outstanding. P.S. I hope that .paddleSports gets deprecated and split into individual activity types like skiing did years ago. Their MET scores are different according to the research on the physical activity compendium site. FB7807902 - Split HKWorkoutActivityType.paddleSports into their own activity types (June 2020)

Apple's sample code 'Trails' supports multiple scenes, however everything is using shared state across the scenes. Put the app in Split View mode and have two windows of the app running and navigate, you can see both mirror each other. Works as designed, it is using a shared 'navigation model' across all scenes. https://developer.apple.com/documentation/appintents/acceleratingappinteractionswithappintents I would like to know if there is a supported or recommended way to modify individual scene storage from within the perform body of an AppIntent. The objective is to have App Shortcuts that launch different tabs in a TabView or different selections in a List. In short, I want to deep link to features, but account for more than one scene being open on iPad and only have programatic navigation happen on the scene that is 'foremost' or the 'activated' one in Split View. I have it working with either a @Dependency or posting a Notification with my main ContentView listening to the other end, but it changes all scenes.
