MKMapView in SwiftUI

MKMapView in SwiftUI

swiftui-mapview

MKMapView in SwiftUI.

For iOS 14 and later, please use Apple's official Map view.

Install

Using Xcode, select File -> Swift Packages -> Add Package Dependency and enter https://github.com/sgade/swiftui-mapview.

Usage

In your view, add the map.
See the example project for how to integrate the map view.

import SwiftUIMapView

struct ContentView: View {
    var body: some View {
        MapView()
    }
}

General

Map type

MapView(mapType: .standard)

User location

Showing the current user location

The current location can be shown on the map. By default, this is true.
Note that the application requires permission to access the current user location.
See the documentation on MapView.showsUserLocation for more information.

MapView(showsUserLocation: true)

Tracking the user's location

MapView(userTrackingMode: .follow)

Region

Setting the visible region center

The binding passed in for center defines the visible region. Setting it to nil will use the map's default region when loaded.
It is also updated when the visible region changes.

@State var center: CLLocationCoordinate2D?

MapView(center: self.$center)

Setting the visible region zoom

The binding passed in for zoom defines the visible region span. A default zoom is used if you do not specify any value.
It is also updated when the visible region changes.

@State var zoom: MKCoordinateSpan

MapView(zoom: self.$zoom)

Annotations

Adding annotations

Annotations are represented as objects of a custom class that implements the MapViewAnnotation protocol.
It might be helpful to sublcass from existing classes like MKPlacemark.

let annotations: [MapViewAnnotation] = ...

MapView(annotation: self.annotations)

Selecting annotations

A list of selected annotations can be passed in via binding.
Selecting an annotations updates the binding, and the other way around.

@State var selectedAnnotations: [MapViewAnnotation] = []

MapView(selectedAnnotations: self.$selectedAnnotations)
