1. Open your Xcode project.
2. Go to File > Swift Packages > Add Package Dependency.
3. Enter the repository URL “https://github.com/mapbox/mapbox-geocoder-swift” and click Next.
4. Select the version of MapboxGeocoder.swift you want to use and click Next.
5. Choose the target where you want to add the package dependency and click Finish.
1. Import the MapboxGeocoder module in your Swift file:
“`swift
import MapboxGeocoder
“`
2. Create an instance of `Geocoder`:
“`swift
let geocoder = Geocoder(accessToken: “YOUR_ACCESS_TOKEN”)
“`
3. Use the geocoder instance to perform geocoding or reverse geocoding. Here’s an example of geocoding an address:
“`swift
let options = ForwardGeocodeOptions(query: “San Francisco, CA”)
geocoder.geocode(options) { (placemarks, attribution, error) in
if let placemark = placemarks?.first {
// Use the placemark to access the geographic coordinates
let coordinates = placemark.location.coordinate
// Perform any additional logic with the coordinates
} else if let error = error {
// Handle the geocoding error
print(“Geocoding failed with error: \(error.localizedDescription)”)
}
}
“`
4. Customize the geocoding or reverse geocoding options as per your requirements. You can specify additional attributes, filters, and scopes to enhance the accuracy and specificity of the results.
– Batch forward geocoding: Geocode multiple addresses at once.
– Caching: Cache geocoding results to improve performance and reduce network usage.
– Localization: Display geocoding results in different languages and units.
1. Geocoding multiple addresses:
“`swift
let addresses = [“San Francisco, CA”, “New York, NY”, “London, UK”]
let options = BatchGeocodeOptions(queries: addresses)
geocoder.geocode(options) { (placemarks, attribution, error) in
if let placemarks = placemarks {
// Iterate through each placemark to access the geocoding results
for placemark in placemarks {
let coordinates = placemark.location.coordinate
// Perform logic for each geocoded address
}
} else if let error = error {
// Handle the geocoding error
print(“Geocoding failed with error: \(error.localizedDescription)”)
}
}
“`
2. Reverse geocoding with custom filters:
“`swift
let coordinates = CLLocationCoordinate2D(latitude: 37.7749, longitude: -122.4194)
let options = ReverseGeocodeOptions(coordinate: coordinates)
options.allowedScopes = [.pointOfInterest, .address]
options.minimumResultBboxSize = CGSize(width: 500, height: 500)
geocoder.geocode(options) { (placemarks, attribution, error) in
if let placemark = placemarks?.first {
// Use the placemark to access the reverse geocoding results
let address = placemark.qualifiedName
// Perform additional logic with the address
} else if let error = error {
// Handle the reverse geocoding error
print(“Reverse geocoding failed with error: \(error.localizedDescription)”)
}
}
“`
