MapKit Reference

Complete MapKit API reference covering SwiftUI Map, MKMapView, annotations, search, directions, Look Around, and snapshots.

When to Use This Reference

Use this reference when:

• Looking up SwiftUI Map content builder API
• Configuring MapCameraPosition for programmatic camera control
• Implementing MKLocalSearch or MKLocalSearchCompleter
• Setting up MKDirections for routing
• Working with Look Around scenes
• Checking iOS version requirements for MapKit features

Example Prompts

• "What's the SwiftUI Map API for annotations?"
• "How do I use MapCameraPosition?"
• "What's the MKLocalSearch API for autocomplete?"
• "How do I calculate directions between two points?"
• "What iOS version added SwiftUI Map?"
• "How do I create a map snapshot image?"

What's Covered

• SwiftUI Map API (content builder, camera position, map controls, styles, selection)
• Map content types (Marker, Annotation, UserAnnotation, shapes)
• MKMapView lifecycle and delegate methods
• Annotation customization and clustering
• MKLocalSearch and MKLocalSearchCompleter
• MKDirections and MKRoute
• Look Around (MKLookAroundScene, LookAroundPreview)
• Overlays and renderers
• Map snapshots (MKMapSnapshotter)
• iOS version feature matrix
• GeoToolbox framework and PlaceDescriptor (iOS 26+)
• MKGeocodingRequest and MKReverseGeocodingRequest
• MKAddress type
