Point Helper - Swift SDK

This example show how to render point features as circles with clustering and labels.

The vector layer helpers take your data and styling options and create the right source + layers on the current map style with minimal code. Helpers normalize sensible defaults like zoom range, outlines, etc. so you can get results quickly.

Basic flow

This example show how to render point features as circles

import MapTilerSDK

// Assume you have an MTMapView already on screen
let mapView: MTMapView = ...

Task { @MainActor in
    guard let style = mapView.style else { return }

    // 1) Pick the helper for your geometry type
    let pointHelper = MTPointLayerHelper(style)

    // 2) Provide data + options
    let options = MTPointLayerOptions(
        data: "https://docs.maptiler.com/sdk-js/assets/earthquakes.geojson",
        pointColor: "#1e90ff",
        pointRadius: 6,
        outline: true,
        outlineColor: "white",
        outlineWidth: 1
    )

    // 3) Add the layer
    await pointHelper.addPoint(options)
}

Points with clustering and labels

import MapTilerSDK

// Assume you have an MTMapView already on screen
let mapView: MTMapView = ...

Task { @MainActor in
    guard let style = mapView.style else { return }

    let helper = MTPointLayerHelper(style)

    // Simple points
    let points = MTPointLayerOptions(
        data: "https://docs.maptiler.com/sdk-js/assets/earthquakes.geojson",
        pointColor: "#1e90ff",
        pointRadius: 6,
        pointOpacity: 0.9,
        outline: true,
        outlineColor: "white",
        outlineWidth: 1
    )
    await helper.addPoint(points)

    // With labels and clustering
    let clustered = MTPointLayerOptions(
        data: "https://docs.maptiler.com/sdk-js/assets/earthquakes.geojson",
        cluster: true,
        showLabel: true,
        labelColor: "#111111"
    )
    await helper.addPoint(clustered)
}
