Update: built to my iPhone running iOS 26 Beta 2 and now choosing it as a run destination seems to work 😅

Update: downloaded Xcode 26 Beta 2 and still get the same errors unless I choose My Mac as my run destination which again I can't do easily on my production app. Is there any other solution?

Also choosing my iPhone which is running iOS Beta 2 produces the same errors as well, is there anything I can do short of adding Mac as a destination?

Ok I figured out the issue by rewatching the WWDC code along. I noticed her run destination in Xcode was Mac whereas mine is Mac (Designed for iPad). I opened a demo project choosing Mac (Designed for iPad) and ran into the same error. Adding Mac as a destination fixed the issue in my demo app but this isn't a great solution for my production app given I have a watch app as well and will have to add a lot of if watchOS code to it to fix the errors adding Mac as a destination.

Thanks, it's difficult to file a feedback since I'd have to zip up my entire app...whereas the model works fine in a brand new project. I can't even get this sample prompt from the documentation to generate a response so I don't think it has to do with the prompt. For this I get this error: "Error: Resource (Local Sanitizer Asset) unavailable error." I can't figure out what might be the cause.

please disregard it seems to be showing up in Apple Fitness now. 👍

@DTS Engineer I was able to write Effort to Apple Health and can see it in the Apple Health App, however in the Apple Fitness App workout Effort does not display the effort that my app saved, and instead it says "skipped." Is there any way to get the workout Effort to display in the Apple Fitness app to count towards Training Load? I've tried both .workoutEffortScore and .estimatedWorkoutEffortScore and it showed skipped for both.

Yes confirmed it's still only 7 days in watchOS 11. 😞

Thanks I've had an open Feedback for this FB12272591 since last WWDC
