@Transient update doesn't propagate to view
When I update a variable inside my model that is marked @Transient, my view does not update with this change. Is this normal? If I update a non-transient variable inside the model at the same time that I update the transient one, then both changes are propagated to my view. Here is an example of the model: @Model public class WaterData { public var target: Double = 3000 @Transient public var samples: [HKQuantitySample] = [] } Updating samples only does not propagate to my view.

How to use `.focusedSceneObject()` with @Observable?
According to docs, .focusedObject() usage should be moved to .focusedValue() when migrating to @Observable, but there is no .focusedSceneValue() overload that accepts Observable like with .focusedValue(). So how are we supposed migrate .focusedSceneObject() to @Observable?
