With Maps in iOS 16, you can use the app to find your way around an airport or shopping mall. Here’s how:
° Do one of the following:
Before you get there: Search for the airport or mall in Maps (tap Indoor Map if it appears in the search result). Or drag the map to show it, zoom in, then tap Look Inside.
When you’re at the airport or mall: Open Maps, tap the right pointing arrow, then tap Look Inside.
° To find nearby services, tap a category (like Food, Restrooms, or Gates) on the place card, then scroll down to see all results. To get more information about a result, tap it.
° To get a map of a different floor, tap the button showing the floor level (zoom in if the button doesn’t appear).
Indoor maps are available for select airports and shopping malls. See the iOS and iPadOS Feature Availability website for more info.
