Reply to Watch app doesn't receive location updates on watchOS 10 beta
I am having the same issue with my app on 10.0.1. Open Water Swim. I only noticed it upon deleting and re-installing the app. If I perform clLocationManager.requestWhenInUseAuthorization() I get a big fat nothing. I will look into that crazy reset procedure and also file a bug report. This is the second bug relating to Core Location. There is also a serious degradation of GPS data (at least on the Ultra). I filed two bugs for this, one in beta FB12587468 and the newer one in release FB13192409. I would say Apple has really introduced some serious issues with core location on this release, and I would not be surprised if some folks end up losing jobs. Good riddance.

Reply to watchOS 10 update has ruined GPS on Ultra during open water swimming.
I am including three example data points that show there is an issue. These are locations that are mathematically impossible because the accuracies provided by the CoreLocation are less than the distances apart. These are CSV files each with two locations separated by a distance greater than the sum of provided accuracies. Typically one second apart (we allow 1 meter per second error) text-FC597A06C33E-1.txt text-4EAA0C645F55-1.txt text-F8A0F1CB22DE-1.txt

Reply to Location Accuracy Reduced on Apple Watch Ultra
I just posted this: https://developer.apple.com/forums/thread/737819 Yes, during Open Water Swims, GPS performance on the ULTRA has degraded severely. We have several users now reporting that the GPS tracks produced during Open water workouts with either built in Workout OR with Open Water Swim are now largely unusable. I have confirmed this with my own swims as well. I would appreciate an upvote on my post as well. BTW, the issue is identical for the built in Workout app during open water swim.
