AI-generated overview

Provides official Mapbox Maps SDK v11 integration patterns for iOS apps in Swift, SwiftUI and UIKit.

What it does: This skill supplies reference guidance and code patterns for integrating the Mapbox Maps SDK v11 into iOS projects. It covers installation and access-token setup, map initialization in SwiftUI and UIKit, adding markers and annotations, showing user location, custom GeoJSON data, map styles, camera control, feature interactions, performance practices and troubleshooting. It produces code snippets and configuration steps rather than runnable scripts.
When to use it: Use it when building or maintaining an iOS app that embeds Mapbox maps and you need concrete patterns for setup, annotations, location display, custom data, styles or gestures. It is also useful when debugging map display, style loading or annotation performance issues.
Requirements: Requires an iOS 14+ project with Xcode 15+ and Swift 5.9+, the Mapbox Maps SDK v11 added via Swift Package Manager, CocoaPods or direct download, and a free Mapbox account with a public access token placed in Info.plist. Location features need CoreLocation permission entries. It ships no scripts; it is instructions and reference documents only.

Map Initialization

SwiftUI Pattern

Basic map:

swift

import SwiftUIimport 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)    }}

import SwiftUIimport 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:

swift

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

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

UIKit Pattern

swift

import UIKitimport 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)    }}

import UIKitimport 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

The SDK offers three ways to place a point on the map. Pick the simplest one that fits.

Agent note: A SwiftUI Mapbox sketch is incomplete without at least one annotation (Marker, PointAnnotation, or MapViewAnnotation). Do not ship a bare Map { } with no pin.

Which API should I use?

API	Use it when	Platforms	Notes
`Marker` (Markers API)	You need a default pin and don't have a custom image asset	SwiftUI only	No image assets required. Experimental SPI — needs `@_spi(Experimental) import MapboxMaps`. Best < 100 markers.
`PointAnnotation`	You have a custom image and want layer-level placement	SwiftUI + UIKit	Backed by a symbol layer, so it scales well to hundreds of markers. Accepts any `UIImage` that `UIKit` can render.
View annotations (`ViewAnnotation` / `MapViewAnnotation`)	You want to render a full native view (card, badge, animated content) anchored to a coordinate	SwiftUI + UIKit	SwiftUI uses `MapViewAnnotation`; UIKit uses `mapView.viewAnnotations` with a `ViewAnnotation`. Each annotation is a real view — costs more than `PointAnnotation` at scale.

For hundreds or thousands of features, use a style layer (SymbolLayer on a GeoJSONSource) instead of annotations.

Markers API (recommended for simple cases, SwiftUI)

swift

import SwiftUI@_spi(Experimental) import MapboxMaps
struct ContentView: View {    var body: some View {        Map {            Marker(coordinate: CLLocationCoordinate2D(latitude: 37.7749, longitude: -122.4194))                .color(.red)                .text("San Francisco")        }    }}

import SwiftUI@_spi(Experimental) import MapboxMaps
struct ContentView: View {    var body: some View {        Map {            Marker(coordinate: CLLocationCoordinate2D(latitude: 37.7749, longitude: -122.4194))                .color(.red)                .text("San Francisco")        }    }}

Multiple markers from a collection:

swift

Map {    ForEvery(locations, id: \.id) { location in        Marker(coordinate: location.coordinate)            .color(.red)            .text(location.name)    }}

Map {    ForEvery(locations, id: \.id) { location in        Marker(coordinate: location.coordinate)            .color(.red)            .text(location.name)    }}

Scaling note. Marker and PointAnnotation each create their own view or symbol entry per pin — fine up to about 100 markers. For larger datasets (hundreds or thousands of features — common with open-ended GeoJSON feeds), load the data into a GeoJSONSource and render it with a SymbolLayer instead. That scales to thousands of features and enables clustering.

PointAnnotation (custom image)

SwiftUI:

swift

Map(viewport: $viewport) {    PointAnnotation(coordinate: CLLocationCoordinate2D(latitude: 37.7749, longitude: -122.4194))        .image(.init(image: UIImage(named: "marker")!, name: "marker"))}

Map(viewport: $viewport) {    PointAnnotation(coordinate: CLLocationCoordinate2D(latitude: 37.7749, longitude: -122.4194))        .image(.init(image: UIImage(named: "marker")!, name: "marker"))}

UIKit:

swift

// Create annotation manager (once, reuse for updates)var pointAnnotationManager = mapView.annotations.makePointAnnotationManager()
// Create markervar annotation = PointAnnotation(coordinate: CLLocationCoordinate2D(latitude: 37.7749, longitude: -122.4194))annotation.image = .init(image: UIImage(named: "marker")!, name: "marker")annotation.iconAnchor = .bottom
// Add to mappointAnnotationManager.annotations = [annotation]

// Create annotation manager (once, reuse for updates)var pointAnnotationManager = mapView.annotations.makePointAnnotationManager()
// Create markervar annotation = PointAnnotation(coordinate: CLLocationCoordinate2D(latitude: 37.7749, longitude: -122.4194))annotation.image = .init(image: UIImage(named: "marker")!, name: "marker")annotation.iconAnchor = .bottom
// Add to mappointAnnotationManager.annotations = [annotation]

Multiple markers:

swift

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

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

Show User Location

Step 1: Add location permission to Info.plist:

Step 2: Request permissions and show location:

swift

import CoreLocation
// Request permissionslet locationManager = CLLocationManager()locationManager.requestWhenInUseAuthorization()
// Show user location puckmapView.location.options.puckType = .puck2D()mapView.location.options.puckBearingEnabled = true

import CoreLocation
// Request permissionslet locationManager = CLLocationManager()locationManager.requestWhenInUseAuthorization()
// Show user location puckmapView.location.options.puckType = .puck2D()mapView.location.options.puckBearingEnabled = true

Performance Best Practices

Reuse Annotation Managers

swift

// ❌ Don't create new managers repeatedlyfunc updateMarkers() {    let manager = mapView.annotations.makePointAnnotationManager()    manager.annotations = markers}
// ✅ Create once, reuselet pointAnnotationManager: PointAnnotationManager
init() {    pointAnnotationManager = mapView.annotations.makePointAnnotationManager()}
func updateMarkers() {    pointAnnotationManager.annotations = markers}

// ❌ Don't create new managers repeatedlyfunc updateMarkers() {    let manager = mapView.annotations.makePointAnnotationManager()    manager.annotations = markers}
// ✅ Create once, reuselet pointAnnotationManager: PointAnnotationManager
init() {    pointAnnotationManager = mapView.annotations.makePointAnnotationManager()}
func updateMarkers() {    pointAnnotationManager.annotations = markers}

Batch Annotation Updates

swift

// ✅ Update all at oncepointAnnotationManager.annotations = newAnnotations
// ❌ Don't update one by onefor annotation in newAnnotations {    pointAnnotationManager.annotations.append(annotation)}

// ✅ Update all at oncepointAnnotationManager.annotations = newAnnotations
// ❌ Don't update one by onefor annotation in newAnnotations {    pointAnnotationManager.annotations.append(annotation)}

Memory Management

swift

// Use weak self in closuresmapView.gestures.onMapTap.observe { [weak self] context in    self?.handleTap(context.coordinate)}.store(in: &cancelables)
// Clean up on deinitdeinit {    cancelables.forEach { $0.cancel() }}

// Use weak self in closuresmapView.gestures.onMapTap.observe { [weak self] context in    self?.handleTap(context.coordinate)}.store(in: &cancelables)
// Clean up on deinitdeinit {    cancelables.forEach { $0.cancel() }}

Use Standard Style

swift

// ✅ Standard style is optimized and recommended.mapStyle(.standard)
// Use other styles only when needed for specific use cases.mapStyle(.standardSatellite) // Satellite imagery

// ✅ 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:

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

Style Not Loading

swift

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

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
