The MapTiler SDK Swift is a native SDK written in Swift, designed to work with the well-established MapTiler Cloud service, which provides all the data required to fuel a complete mobile mapping experience: vector tiles, geojson, map interaction, custom styles, data visualization and more.

MapTiler Swift SDK is a Swift Package and can be added as dependency through Swift Package Manager.
- File -> Add Package Dependencies
- Add https://github.com/maptiler/maptiler-sdk-swift.git
Make sure to set your MapTiler Cloud API key first. (i.e. in AppDelegate):
Task {
await MTConfig.shared.setAPIKey("YOUR_API_KEY")
}import MapTilerSDK
let coordinates = CLLocationCoordinate2D(latitude: 47.137765, longitude: 8.581651)
let options = MTMapOptions(center: coordinates, zoom: 2.0, bearing: 1.0, pitch: 20.0)
var mapView = MTMapView(frame: view.frame, options: options, referenceStyle: .streets)
mapView.delegate = self
view.addSubview(mapView)If you are using auto layout, you can call the helper function for anchors pinning. This ensures correct orientation updates.
mapView.pinToSuperviewEdges()import MapTilerSDK
@State private var mapView = MTMapView(options: MTMapOptions(zoom: 2.0))
var body: some View {
MTMapViewContainer(map: mapView) {}
.referenceStyle(.streets)
}For detailed functionality overview refer to the API Reference documentation or build local docs in Xcode: Product -> Build Documentation.
Check out the full list of MapTiler SDK Swift examples or browse ready-to-use code examples at the Examples directory in this repo.

Sources and layers can be added to the map view style object as soon as map is initialized. Setting the style after adding layers resets them to default, so make sure style is finished loading first.
guard let style = mapView.style else {
return
}
if let contoursTilesURL = URL(string: "https://api.maptiler.com/tiles/contours-v2/tiles.json?key=YOUR_API_KEY") {
let contoursDataSource = MTVectorTileSource(identifier: "contoursSource", url: contoursTilesURL)
style.addSource(contoursDataSource)
let contoursLayer = MTLineLayer(identifier: "contoursLayer", sourceIdentifier: contoursDataSource.identifier, sourceLayer: "contour_ft")
contoursLayer.color = .brown
contoursLayer.width = 2.0
style.addLayer(contoursLayer)
}@State private var mapView = MTMapView(options: MTMapOptions(zoom: 2.0))
var body: some View {
MTMapViewContainer(map: mapView) {
MTVectorTileSource(identifier: "countoursSource", url: URL(string: "https://api.maptiler.com/tiles/contours-v2/tiles.json?key=YOUR_API_KEY"))
MTLineLayer(identifier: "contoursLayer", sourceIdentifier: "countoursSource", sourceLayer: "contour_ft")
.color(.brown)
.width(2.0)
}
}Markers and popups (Text, Custom Annotation) can be used for highlighting points of interest on the map.
let coordinates = CLLocationCoordinate2D(latitude: 47.137765, longitude: 8.581651)
let popup = MTTextPopup(coordinates: coordinates, text: "MapTiler", offset: 20.0)
let marker = MTMarker(coordinates: coordinates, popup: popup)
marker.draggable = true
mapView.addMarker(marker)@State private var mapView = MTMapView(options: MTMapOptions(zoom: 2.0))
let coordinates = CLLocationCoordinate2D(latitude: 47.137765, longitude: 8.581651)
var body: some View {
MTMapViewContainer(map: mapView) {
let popup = MTTextPopup(coordinates: coordinates, text: "MapTiler", offset: 20.0)
MTMarker(coordinates: coordinates, draggable: true, popup: popup)
}
}Alternatively add content on custom actions:
@State private var mapView = MTMapView(options: MTMapOptions(zoom: 2.0))
let coordinates = CLLocationCoordinate2D(latitude: 47.137765, longitude: 8.581651)
var body: some View {
MTMapViewContainer(map: mapView) {
}
.didInitialize {
let marker = MTMarker(coordinates: coordinates)
Task {
await mapView.addMarker(marker)
}
}
Button("Add Popup") {
Task {
let popup = MTTextPopup(coordinates: coordinates, text: "MapTiler", offset: 20.0)
await mapView.addTextPopup(popup)
}
}
}For additional examples refer to the Examples directory.
In addition to MTMarker and MTTextPopup, you can use MTCustomAnnotationView class to make your own annotations and add them to the map. You can subclass to create custom UI it or use it as is for simple designs.
let customSize = CGSize(width: 200.0, height: 80.0)
let coordinates = CLLocationCoordinate2D(latitude: 47.137765, longitude: 8.581651)
let offset = MTPoint(x: 0, y: -80)
let myCustomView = MTCustomAnnotationView(size: customSize, coordinates: coordinates, offset: offset)
myCustomView.backgroundColor = .blue
myCustomView.addTo(mapView)The space option customizes the globe’s background, simulating deep space or skybox effects.
- Prerequisite: use globe projection. Set
projection: .globeinMTMapOptions.
Usage — solid color background
import MapTilerSDK
// UIKit
let options = MTMapOptions(
projection: .globe,
space: .config(
MTSpace(
color: MTColor(color: UIColor(hex: "#111122")!.cgColor)
)
)
)
let mapView = MTMapView(frame: view.bounds, options: options, referenceStyle: .streets)
// SwiftUI
@State private var mapView = MTMapView(
options: MTMapOptions(
projection: .globe,
space: .config(MTSpace(color: MTColor(color: UIColor(hex: "#111122")!.cgColor)))
)
)Presets — predefined cubemaps
space: Dark blue background; stars stay white. Space color changes background color.stars(default): Black background; space color changes stars color.milkyway: Black half‑transparent background with standard milky way and stars; space color tints stars and milky way.milkyway-subtle: Subtle milky way, fewer stars; space color tints stars and milky way.milkyway-bright: Bright milky way, more stars; space color tints stars and milky way.milkyway-colored: Full image with natural colors; space color has no effect.
// Use a preset
let options = MTMapOptions(
projection: .globe,
space: .config(MTSpace(preset: .space))
)Custom cubemap — provide all faces
let faces = MTSpaceFaces(
pX: URL(string: "https://example.com/space/px.png")!,
nX: URL(string: "https://example.com/space/nx.png")!,
pY: URL(string: "https://example.com/space/py.png")!,
nY: URL(string: "https://example.com/space/ny.png")!,
pZ: URL(string: "https://example.com/space/pz.png")!,
nZ: URL(string: "https://example.com/space/nz.png")!
)
let options = MTMapOptions(
projection: .globe,
space: .config(MTSpace(faces: faces))
)Cubemap by path — files named px, nx, py, ny, pz, nz with the given format
let path = MTSpacePath(
baseUrl: URL(string: "https://example.com/spacebox/transparent")!,
format: "png" // defaults to PNG if omitted
)
let options = MTMapOptions(
projection: .globe,
space: .config(MTSpace(path: path))
)Dynamic updates — change space at runtime
mapView.didInitialize = {
Task {
await mapView.setSpace(
.config(
MTSpace(
color: MTColor(color: UIColor.red.cgColor),
path: MTSpacePath(baseUrl: URL(string: "https://example.com/spacebox/transparent")!)
)
)
)
}
}Note: When calling setSpace, any field not explicitly provided (e.g., color, faces, path, or preset) keeps its previous value.
The halo option adds a gradient-based atmospheric glow around the globe, simulating the visual effect of Earth's atmosphere when viewed from space.
- Prerequisite: use globe projection. Set
projection: .globeinMTMapOptions.
Usage — enable simple halo
import MapTilerSDK
// UIKit
let options = MTMapOptions(
projection: .globe,
halo: .enabled(true)
)
let mapView = MTMapView(frame: view.bounds, options: options, referenceStyle: .outdoor)
// SwiftUI
@State private var mapView = MTMapView(
options: MTMapOptions(
projection: .globe,
halo: .enabled(true)
)
)Custom gradient — scale and stops
let options = MTMapOptions(
projection: .globe,
halo: .config(
MTHalo(
scale: 1.5, // Controls the halo size
stops: [
MTHaloStop(position: 0.2, color: MTColor(hex: "#00000000")),
MTHaloStop(position: 0.2, color: MTColor(hex: "#FF0000")),
MTHaloStop(position: 0.4, color: MTColor(hex: "#FF0000")),
MTHaloStop(position: 0.4, color: MTColor(hex: "#00000000")),
MTHaloStop(position: 0.6, color: MTColor(hex: "#00000000")),
MTHaloStop(position: 0.6, color: MTColor(hex: "#FF0000")),
MTHaloStop(position: 0.8, color: MTColor(hex: "#FF0000")),
MTHaloStop(position: 0.8, color: MTColor(hex: "#00000000")),
MTHaloStop(position: 1.0, color: MTColor(hex: "#00000000"))
]
)
)
)Dynamic updates — change halo at runtime
mapView.didInitialize = {
Task {
await mapView.setHalo(
.config(
MTHalo(
scale: 2.0,
stops: [
MTHaloStop(position: 0.0, color: MTColor(hex: "#87CEFA")),
MTHaloStop(position: 0.5, color: MTColor(hex: "#0000FABF")),
MTHaloStop(position: 0.75, color: MTColor(hex: "#FF000000"))
]
)
)
)
}
}Disable animations — halo and space
mapView.didInitialize = {
Task {
await mapView.disableHaloAnimations()
await mapView.disableSpaceAnimations()
}
