AVExperienceController.TransitionContext
The state of the transition provided to the delegate object.
Declaration
struct TransitionContextOverview
When AVExperienceController transitions its experience from fromExperience to toExperience, delegate callbacks provide instances of TransitionContext to allow clients to respond as the transition progresses or reverts. The normal Status sequence is .preparing -> .transitioning -> .completed Once .completed, AVExperienceController’s experience is now the toExperience.
Not all transitions are .completed, instead they are .reversed back to the fromExperience. Reversed transitions can happen after .preparing or after .transitioning, but it will not happen after .completed or before .preparing. When a transition is reversed a reason is provided.
