@diagnose(DeprecatedDeclaration, as: ignore, reason: "Waiting for replacement API") - a cool new Swift feature!

This is new, or new since I last looked. Thank you much!

My feedback from fall was referenced in the original post above. FB20959748

I'm not planning on moving away from the CloudKit.framework to the contrary I'm running towards CKSyncEngine, I was just illustrating the design philosophy for observability and my fondness of ClientMiddleware which is so underutilized for mobile dev. The caching is very useful, years ago I went digging in the app container. In the process of trying to replicate it for Swift on Server and CLI tools, I ran into a roadblock because I couldn't get the checksum officially documented (FB9826224).

Thanks for sharing my feedback ID @DTS Engineer! I almost forgot about this one. I'm updating it with some new context! Widget Extension running against the memory limit would be good. Potentially a different ask but related. Feedback updated. I assume/speculate that any upcoming system extensions that power app intents with Siri would have strict memory footprint limits.

@DTS Engineer Fixed for AgeRangeDeclaration, but not ParentalControls property for significant change. FB21340649 - DeclaredAgeRange: Production Issue - AgeRangeService.ParentalControls.significantAppChangeApprovalRequired causes crashes on iOS 26.0 and 26.1 devices

@DTS Engineer you or others may have already seen this one but just in case you haven't. FB21240249 - DeclaredAgeRange: DeclaredAgeRangeAction symbol unavailable on macOS catalyst apps causing crash - documentation says otherwise

@DTS Engineer Thanks for confirming, I can put my availability check in my code and just comment it out until Xcode is also fixed. The availability in Xcode headers also says 26.0. I did confirm it works as expected on an iOS 26.2 device.

@DTS Engineer Using Xcode 26.2, targeting an iPhone 17 Pro running 26.1, Xcode crashes saying the symbol isn't available. FB21116398. This is the case accessing both the eligibility property, as well as the additional age range declaration enum cases.

@DTS Engineer, if I receive this error code when attempting to create records, what are your thoughts on me traversing the sandbox and deleting the CloudKit directory to mitigate this? Hopefully a fix in 18.4 or later, but is there anything I can do safely now?

FB16452716 - Core Location / Documentation: Create documentation about NSLocationRequireExplicitServiceSession since it is missing from Core Location docs

@DTS Engineer The Swift Charts example code falls into this trap too. It embeds a NavigationSplitView inside a TabView. This sample code should be updated if this layout is to be avoided because it causes unexpected behaviors. I was just running this example code and the view modifier to require tabs wasn't being respected. I guess 'as designed'? https://developer.apple.com/documentation/charts/visualizing_your_app_s_data

FB15382945 - HealthKit: Give third party developers access to the internal heart rate zones recorded and associated with Activity app workouts

@cfc I have successfully saved and related .workoutEffortScore samples to workouts, just like the Fitness apps. The documentation is practically non-existent on the new types. To make matters worse, there was no developer session describing these APIs at WWDC24. If you're the author of the workout, it should just work. You do need to query the sample and use a workout predicate to fetch it. It doesn't add the sample to the workout like the Builder API does with other sample types.
