• Geometry libraries - KML and GeoJSON rendering
• Geometry utilities - Handy spherical geometry utility functions
• Heatmaps - Heatmap rendering
• Marker clustering — handles the display of a large number of points
• Marker customization - display custom markers
• Quadtree data structure - indexes 2D geometry points and performs 2D range queries

• iOS 11.0+

Installation

CocoaPods

In your Podfile:

use_frameworks!

target 'TARGET_NAME' do
    pod 'Google-Maps-iOS-Utils', '~> 4.1.0'
end

Replace TARGET_NAME and then, in the Podfile directory, type:

$ pod install

Carthage

In your Cartfile:

github "googlemaps/google-maps-ios-utils" ~> 4.1.0

See the Carthage doc for further installation instructions.

Swift Package Manager

Note: This feature is only available with Swift 5.3 (Xcode 12) or later.

Add the following to your dependencies value of your Package.swift file.

dependencies: [
  .package(
    url: "https://github.com/googlemaps/google-maps-ios-utils.git",

In addition to this, you will also have to include the GoogleMaps dependency using one of the available installation options (CocoaPods, Carthage, or manual)

Samples and Example Usage

e.g. Displaying KML data

import GoogleMapsUtils

func renderKml() {
    // Parse KML
    let path: String = // Path to your KML file...
    let kmlUrl = URL(fileURLWithPath: path)
    let kmlParser = GMUKmlParser(url: kmlUrl)
    kmlParser.parse()

    // Render parsed KML
    let renderer = GMUGeometryRenderer(
        map: mapView,
        geometries: kmlParser.placemarks,
        styles: kmlParser.styles,
        styleMaps: kmlParser.styleMaps
    )
    renderer.render()
}

You can see more example usages in our sample projects.
