AI-generated Key Takeaways

• GMSIndoorDisplayDelegate handles events related to indoor maps, such as changes to the active building or level.

• The delegate provides optional methods, didChangeActiveBuilding and didChangeActiveLevel, which are called when the active building or level is changed, respectively.

• When the active building changes, didChangeActiveBuilding is raised first, followed by didChangeActiveLevel to reflect the new building's active level.

• didChangeActiveLevel is triggered for any changes to the active level, including explicit settings.
