Mapbox iOS Integration Patterns

Official patterns for integrating Mapbox Maps SDK v11 on iOS with Swift, SwiftUI, and UIKit.

Use this skill when:

• Installing and configuring Mapbox Maps SDK for iOS
• Adding markers and annotations to maps
• Showing user location and tracking with camera
• Adding custom data (GeoJSON) to maps
• Working with map styles, camera, or user interaction
• Handling feature interactions and taps

Official Resources:

• iOS Maps Guides
• API Reference
• Example Apps

Installation & Setup

Requirements

• iOS 12+
• Xcode 15+
• Swift 5.9+
• Free Mapbox account

Step 1: Configure Access Token

Add your public token to Info.plist:

<key>MBXAccessToken</key>
<string>pk.your_mapbox_token_here</string>

Get your token: Sign in at mapbox.com

Step 2: Add Swift Package Dependency

1. File → Add Package Dependencies
2. Enter URL: https://github.com/mapbox/mapbox-maps-ios.git
3. Version: "Up to Next Major" from 11.0.0
4. Verify four dependencies appear: MapboxCommon, MapboxCoreMaps, MapboxMaps, Turf

Alternative: CocoaPods or direct download (install guide)

Map Initialization

SwiftUI Pattern (iOS 13+)

Basic map:

import SwiftUI
import MapboxMaps

struct ContentView: View {
    @State private var viewport: Viewport = .camera(
        center: CLLocationCoordinate2D(latitude: 37.7749, longitude: -122.4194),
        zoom: 12
    )

    var body: some View {
        Map(viewport: $viewport)
            .mapStyle(.standard)
    }
}

With ornaments:

Map(viewport: $viewport)
    .mapStyle(.standard)
    .ornamentOptions(OrnamentOptions(
        scaleBar: .init(visibility: .visible),
        compass: .init(visibility: .adaptive),
        logo: .init(position: .bottomLeading)
    ))

UIKit Pattern

import UIKit
import MapboxMaps

class MapViewController: UIViewController {
    private var mapView: MapView!

    override func viewDidLoad() {
        super.viewDidLoad()

        let options = MapInitOptions(
            cameraOptions: CameraOptions(
                center: CLLocationCoordinate2D(latitude: 37.7749, longitude: -122.4194),
                zoom: 12
            )
        )

        mapView = MapView(frame: view.bounds, mapInitOptions: options)
        mapView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
        view.addSubview(mapView)

        mapView.mapboxMap.loadStyle(.standard)
    }
}

Add Markers (Annotations)

Point Annotations (Markers)

Point annotations are the most common way to mark locations on the map.

SwiftUI:

Map(viewport: $viewport) {
    PointAnnotation(coordinate: CLLocationCoordinate2D(latitude: 37.7749, longitude: -122.4194))
        .iconImage("custom-marker")
}

UIKit:

// Create annotation manager (once, reuse for updates)
var pointAnnotationManager = mapView.annotations.makePointAnnotationManager()

// Create marker
var annotation = PointAnnotation(coordinate: CLLocationCoordinate2D(latitude: 37.7749, longitude: -122.4194))
annotation.image = .init(image: UIImage(named: "marker")!, name: "marker")
annotation.iconAnchor = .bottom

// Add to map
pointAnnotationManager.annotations = [annotation]

Multiple markers:

let locations = [
    CLLocationCoordinate2D(latitude: 37.7749, longitude: -122.4194),
    CLLocationCoordinate2D(latitude: 37.7849, longitude: -122.4094),
    CLLocationCoordinate2D(latitude: 37.7649, longitude: -122.4294)
]

let annotations = locations.map { coordinate in
    var annotation = PointAnnotation(coordinate: coordinate)
    annotation.image = .init(image: UIImage(named: "marker")!, name: "marker")
    return annotation
}

pointAnnotationManager.annotations = annotations

Circle Annotations

var circleAnnotationManager = mapView.annotations.makeCircleAnnotationManager()

var circle = CircleAnnotation(coordinate: coordinate)
circle.circleRadius = 10
circle.circleColor = StyleColor(.red)

circleAnnotationManager.annotations = [circle]

Polyline Annotations

var polylineAnnotationManager = mapView.annotations.makePolylineAnnotationManager()

let coordinates = [coord1, coord2, coord3]
var polyline = PolylineAnnotation(lineCoordinates: coordinates)
polyline.lineColor = StyleColor(.blue)
polyline.lineWidth = 4

polylineAnnotationManager.annotations = [polyline]

Polygon Annotations

var polygonAnnotationManager = mapView.annotations.makePolygonAnnotationManager()

let coordinates = [coord1, coord2, coord3, coord1] // Close the polygon
var polygon = PolygonAnnotation(polygon: .init(outerRing: .init(coordinates)))
polygon.fillColor = StyleColor(.blue.withAlphaComponent(0.5))
polygon.fillOutlineColor = StyleColor(.blue)

polygonAnnotationManager.annotations = [polygon]

Show User Location

Display User Location

Step 1: Add location permission to Info.plist:

<key>NSLocationWhenInUseUsageDescription</key>
<string>Show your location on the map</string>

Step 2: Request permissions and show location:

import CoreLocation

// Request permissions
let locationManager = CLLocationManager()
locationManager.requestWhenInUseAuthorization()

// Show user location puck
mapView.location.options.puckType = .puck2D()
mapView.location.options.puckBearingEnabled = true

Camera Follow User Location

To make the camera follow the user's location as they move:

import Combine

class MapViewController: UIViewController {
    private var mapView: MapView!
    private var cancelables = Set<AnyCancellable>()

    override func viewDidLoad() {
        super.viewDidLoad()
        setupMap()
        setupLocationTracking()
    }

    func setupLocationTracking() {
        // Request permissions
        let locationManager = CLLocationManager()
        locationManager.requestWhenInUseAuthorization()

        // Show user location
        mapView.location.options.puckType = .puck2D()
        mapView.location.options.puckBearingEnabled = true

        // Follow user location with camera
        mapView.location.onLocationChange.observe { [weak self] locations in
            guard let self = self, let location = locations.last else { return }

            self.mapView.camera.ease(to: CameraOptions(
                center: location.coordinate,
                zoom: 15,
                bearing: location.course >= 0 ? location.course : nil,
                pitch: 45
            ), duration: 1.0)
        }.store(in: &cancelables)
    }
}

Get Current Location Once

if let location = mapView.location.latestLocation {
    let coordinate = location.coordinate
    print("User at: \(coordinate.latitude), \(coordinate.longitude)")

    // Move camera to user location
    mapView.camera.ease(to: CameraOptions(
        center: coordinate,
        zoom: 14
    ), duration: 1.0)
}

Add Custom Data (GeoJSON)

Add your own data to the map using GeoJSON sources and layers.

Add Line (Route, Path)

// Create coordinates for the line
let routeCoordinates = [
    CLLocationCoordinate2D(latitude: 37.7749, longitude: -122.4194),
    CLLocationCoordinate2D(latitude: 37.7849, longitude: -122.4094),
    CLLocationCoordinate2D(latitude: 37.7949, longitude: -122.3994)
]

// Create GeoJSON source
var source = GeoJSONSource(id: "route-source")
source.data = .geometry(.lineString(LineString(routeCoordinates)))

try? mapView.mapboxMap.addSource(source)

// Create line layer
var layer = LineLayer(id: "route-layer", source: "route-source")
layer.lineColor = .constant(StyleColor(.blue))
layer.lineWidth = .constant(4)
layer.lineCap = .constant(.round)
layer.lineJoin = .constant(.round)

try? mapView.mapboxMap.addLayer(layer)

Add Polygon (Area)

let polygonCoordinates = [coord1, coord2, coord3, coord1] // Close the polygon

var source = GeoJSONSource(id: "area-source")
source.data = .geometry(.polygon(Polygon([polygonCoordinates])))

try? mapView.mapboxMap.addSource(source)

var fillLayer = FillLayer(id: "area-fill", source: "area-source")
fillLayer.fillColor = .constant(StyleColor(.blue.withAlphaComponent(0.3)))
fillLayer.fillOutlineColor = .constant(StyleColor(.blue))

try? mapView.mapboxMap.addLayer(fillLayer)

Add Points from GeoJSON

let geojsonString = """
{
  "type": "FeatureCollection",
  "features": [
    {
      "type": "Feature",
      "geometry": {"type": "Point", "coordinates": [-122.4194, 37.7749]},
      "properties": {"name": "Location 1"}
    },
    {
      "type": "Feature",
      "geometry": {"type": "Point", "coordinates": [-122.4094, 37.7849]},
      "properties": {"name": "Location 2"}
    }
  ]
}
"""

var source = GeoJSONSource(id: "points-source")
source.data = .string(geojsonString)

try? mapView.mapboxMap.addSource(source)

var symbolLayer = SymbolLayer(id: "points-layer", source: "points-source")
symbolLayer.iconImage = .constant(.name("marker"))
symbolLayer.textField = .constant(.expression(Exp(.get) { "name" }))
symbolLayer.textOffset = .constant([0, 1.5])

try? mapView.mapboxMap.addLayer(symbolLayer)

Update Layer Properties

try? mapView.mapboxMap.updateLayer(
    withId: "route-layer",
    type: LineLayer.self
) { layer in
    layer.lineColor = .constant(StyleColor(.red))
    layer.lineWidth = .constant(6)
}

Remove Layers and Sources

try? mapView.mapboxMap.removeLayer(withId: "route-layer")
try? mapView.mapboxMap.removeSource(withId: "route-source")

Camera Control

Set Camera Position

// SwiftUI - Update viewport state
viewport = .camera(
    center: CLLocationCoordinate2D(latitude: 40.7128, longitude: -74.0060),
    zoom: 14,
    bearing: 90,
    pitch: 60
)

// UIKit - Immediate
mapView.mapboxMap.setCamera(to: CameraOptions(
    center: CLLocationCoordinate2D(latitude: 40.7128, longitude: -74.0060),
    zoom: 14,
    bearing: 90,
    pitch: 60
))

Animated Camera Transitions

// Fly animation (dramatic arc)
mapView.camera.fly(to: CameraOptions(
    center: destination,
    zoom: 15
), duration: 2.0)

// Ease animation (smooth)
mapView.camera.ease(to: CameraOptions(
    center: destination,
    zoom: 15
), duration: 1.0)

Fit Camera to Coordinates

let coordinates = [coord1, coord2, coord3]
let camera = mapView.mapboxMap.camera(for: coordinates,
                                       padding: UIEdgeInsets(top: 50, left: 50, bottom: 50, right: 50),
                                       bearing: 0,
                                       pitch: 0)
mapView.camera.ease(to: camera, duration: 1.0)

Map Styles

Built-in Styles

// SwiftUI
Map(viewport: $viewport)
    .mapStyle(.standard)        // Mapbox Standard (recommended)
    .mapStyle(.streets)          // Mapbox Streets
    .mapStyle(.outdoors)         // Mapbox Outdoors
    .mapStyle(.light)            // Mapbox Light
    .mapStyle(.dark)             // Mapbox Dark
    .mapStyle(.standardSatellite) // Satellite imagery

// UIKit
mapView.mapboxMap.loadStyle(.standard)
mapView.mapboxMap.loadStyle(.streets)
mapView.mapboxMap.loadStyle(.dark)

Custom Style URL

// SwiftUI
Map(viewport: $viewport)
    .mapStyle(MapStyle(uri: StyleURI(url: customStyleURL)!))

// UIKit
mapView.mapboxMap.loadStyle(StyleURI(url: customStyleURL)!)

Style from Mapbox Studio:

let styleURL = URL(string: "mapbox://styles/username/style-id")!

User Interaction & Feature Taps

Featureset Interactions (Recommended)

The modern Interactions API allows handling taps on map features with typed feature access. Works with Standard Style predefined featuresets like POIs, buildings, and place labels.

SwiftUI Pattern:

import SwiftUI
import MapboxMaps

struct MapView: View {
    @State private var viewport: Viewport = .camera(
        center: CLLocationCoordinate2D(latitude: 37.7749, longitude: -122.4194),
        zoom: 12
    )
    @State private var selectedBuildings = [StandardBuildingsFeature]()

    var body: some View {
        Map(viewport: $viewport) {
            // Tap on POI features
            TapInteraction(.standardPoi) { poi, context in
                print("Tapped POI: \(poi.name ?? "Unknown")")
                return true // Stop propagation
            }

            // Tap on buildings and collect selected buildings
            TapInteraction(.standardBuildings) { building, context in
                print("Tapped building")
                selectedBuildings.append(building)
                return true
            }

            // Apply feature state to selected buildings (highlighting)
            ForEvery(selectedBuildings, id: \.id) { building in
                FeatureState(building, .init(select: true))
            }
        }
        .mapStyle(.standard)
    }
}

UIKit Pattern:

import MapboxMaps
import Combine

class MapViewController: UIViewController {
    private var mapView: MapView!
    private var cancelables = Set<AnyCancellable>()

    override func viewDidLoad() {
        super.viewDidLoad()
        setupMap()
        setupInteractions()
    }

    func setupInteractions() {
        // Tap on POI features
        let poiToken = mapView.mapboxMap.addInteraction(
            TapInteraction(.standardPoi) { [weak self] poi, context in
                print("Tapped POI: \(poi.name ?? "Unknown")")
                return true
            }
        )

        // Tap on buildings
        let buildingToken = mapView.mapboxMap.addInteraction(
            TapInteraction(.standardBuildings) { [weak self] building, context in
                print("Tapped building")

                // Highlight the building using feature state
                self?.mapView.mapboxMap.setFeatureState(
                    building,
                    state: ["select": true]
                )
                return true
            }
        )

        // Store tokens to keep interactions active
        // Cancel tokens when done: poiToken.cancel()
    }
}

Tap on Custom Layers

let token = mapView.mapboxMap.addInteraction(
    TapInteraction(.layer("custom-layer-id")) { feature, context in
        if let properties = feature.properties {
            print("Feature properties: \(properties)")
        }
        return true
    }
)

Long Press Interactions

let token = mapView.mapboxMap.addInteraction(
    LongPressInteraction(.standardPoi) { poi, context in
        print("Long pressed POI: \(poi.name ?? "Unknown")")
        return true
    }
)

Handle Map Taps (Empty Space)

// UIKit
mapView.gestures.onMapTap.observe { [weak self] context in
    let coordinate = context.coordinate
    print("Tapped map at: \(coordinate.latitude), \(coordinate.longitude)")
}.store(in: &cancelables)

Gesture Configuration

// Disable specific gestures
mapView.gestures.options.pitchEnabled = false
mapView.gestures.options.rotateEnabled = false

// Configure zoom limits
mapView.mapboxMap.setCamera(to: CameraOptions(
    zoom: 12,
    minZoom: 10,
    maxZoom: 16
))

Performance Best Practices

Reuse Annotation Managers

// ❌ Don't create new managers repeatedly
func updateMarkers() {
    let manager = mapView.annotations.makePointAnnotationManager()
    manager.annotations = markers
}

// ✅ Create once, reuse
let pointAnnotationManager: PointAnnotationManager

init() {
    pointAnnotationManager = mapView.annotations.makePointAnnotationManager()
}

func updateMarkers() {
    pointAnnotationManager.annotations = markers
}

Batch Annotation Updates

// ✅ Update all at once
pointAnnotationManager.annotations = newAnnotations

// ❌ Don't update one by one
for annotation in newAnnotations {
    pointAnnotationManager.annotations.append(annotation)
}

Memory Management

// Use weak self in closures
mapView.gestures.onMapTap.observe { [weak self] context in
    self?.handleTap(context.coordinate)
}.store(in: &cancelables)

// Clean up on deinit
deinit {
    cancelables.forEach { $0.cancel() }
}

Use Standard Style

// ✅ Standard style is optimized and recommended
.mapStyle(.standard)

// Use other styles only when needed for specific use cases
.mapStyle(.standardSatellite) // Satellite imagery

Troubleshooting

Map Not Displaying

Check:

1. ✅ MBXAccessToken in Info.plist
2. ✅ Token is valid (test at mapbox.com)
3. ✅ MapboxMaps framework imported
4. ✅ MapView added to view hierarchy
5. ✅ Correct frame/constraints set

Style Not Loading

mapView.mapboxMap.onStyleLoaded.observe { [weak self] _ in
    print("Style loaded successfully")
    // Add layers and sources here
}.store(in: &cancelables)

Performance Issues

• Use .standard style (recommended and optimized)
• Limit visible annotations to viewport
• Reuse annotation managers
• Avoid frequent style reloads
• Batch annotation updates
