Xcode 16 gives this warning for this line in FerrostarCore package:

Main actor-isolated instance method 'locationManager(_:didUpdateLocations:)' cannot be used to satisfy nonisolated protocol requirement; this is an error in the Swift 6 language mode

That's correct. It's a known limitation. As far as we are aware, the current code is safe, but due to a variety of reasons, it's not possible for us to satisfy the Swift 6 strict concurrency checker ;) Long-term we want to transition this to an actor type, but it's not high enough priority quite yet.
