LocationPicker for SwiftUI is a Swift package that provides an easy-to-use SwiftUI view for interactive input of geographic coordinates.
First you need to create a view with a @Binding property of CLLocationCoordinate2D type (remember to import the MapKit framework!) inside. This means that once the position is selected, coordinates are directly passed to your previous view through the powerful binding system of SwiftUI without any additional effort. Now put the LocationPicker view into a Sheet or a NavigationLink passing the binding value previously mentioned.
The user is now free to navigate around the map and select the location. Once pressed anywhere on the map, an annotation will appear on the map while coordinates are always displayed in real time at the bottom of the screen. You can also provide a custom text to tell the user what to do.
Here's a short usage example. You can find the full code in UsageExample.swift
@State private var coordinates = CLLocationCoordinate2D(latitude: 37.333747, longitude: -122.011448)
@State private var showSheet = false
var body: some View {
VStack {
Text("\(coordinates.latitude), \(coordinates.longitude)")
Button("Select location") {
self.showSheet.toggle()
}
}
.sheet(isPresented: $showSheet) {
LocationPicker(instructions: "Tap to select coordinates", coordinates: $coordinates, dismissOnSelection: true)
}
}Required:
- iOS 14.0 or above
- Xcode 12.0 or above
