This open-source library contains classes that are useful for a wide range of applications using the Google Maps SDK for iOS.

• 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 9.0+
• CocoaPods

In your Podfile:

use_frameworks!

target 'TARGET_NAME' do
    pod 'Google-Maps-iOS-Utils', '~> 3.4.1'

    .upToNextMinor(from: "3.4.1")
  )
]

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()
}
