Reply to DeviceHub Not showing simulator
I had this issue, I could only use Device Hub with my own devices, no simulator would appear and I couldn't "see" my app when running it on a simulator even though there was console output. The fix for me was rebooting my Mac so I presume it's a bug. Fingers crossed this works for you!

Reply to Health data on iPad via iCloud
Sorry, I‘ve not been clear enough with the question, I’m trying to determine if the device is viewing the Health data via synchronised iCloud or directly on device. The reason being the data via iCloud is often is delayed and so I’m trying to ensure I can provide the right experience to the user and set expectations. My app displays Apple Watch Health data and generally the paired iPhone‘s Health data stays right up to date with Apple Watch, but this isn’t the case for the iPad that also accesses the same data via iCloud. It’s not explicitly clear, but this delay issue might be something that is improved with the new 27 releases?

Reply to WatchOS HealthKit HKObserverQuery crashes in background
I would very much like this to still be solved, even better for WatchOS 10, 11 & 26 as well 😁

Reply to watchOS: Is there a public API to initiate an HRV measurement?
I don't believe there's an API for this. I'm pretty sure it came up in this years WatchOS lab at WWDC26 and no luck. It's been requested for a while but for what ever reason 🤷‍♂️

I've submitted a new bug report FB24132300 replacing FB22115840. The issue still occurs on the latest release of WatchOS 26.6 AND on WatchOS 27 beta 4. Have also provided an updated and simplified sample project in the feedback. Anyone? Thank you 🙏

Reply to Can any Apple Watch running WatchOS 27 access PCC via Foundation Models?
I have the answer here I think. No, not only does the Watch have to be running WatchOS 27, it also needs to be paired to an iPhone with Apple Intelligence enabled. This is despite the fact that PCC queries from WatchOS 27 go straight to the server and don't require the paired iPhone at all 🤷‍♂️

Reply to Snippet Views don't render consistently, width not always respected
Hi lliyanke! No, I put that feedback in Nov 18, 2025, it was like putting a message in a bottle and throwing it in the ocean.....😯 So yes, never heard anything which is odd given Snippets were new. I'm still seeing the issue in iOS 27, although I haven't rebuilt the app with the new SDK incase that could help...

Reply to Sleep Disturbances API enhancements
ECGs have dedicated sample data when using the simulator and the Apple Health app. Something similar for this and a few other key types like Heart Rate Notifications would be very useful.

Reply to Cardio Fitness / VO2Max data Generation
Is there any documentation or guides anywhere to indicate the duration/type/intensity of workout required to generate these VO2Max and Cardio Recovery values?

@DTS Engineer Any updates on this given the recent updates with WatchOS 27? That being said, a lot of my users will be staying on WatchOS 26 so I'm really still looking for a fix there as well! 🤞

These crashes are essentially what I'm still seeing in WatchOS 26.4 here
