Implement API key authentication

You need an access token to use the location services used in this tutorial.

1. Go to the Create an API key tutorial to obtain a new API key access token.

   • Ensure that the following privilege is enabled: Location services > Basemaps > Basemap styles service.

   • Copy the access token as it will be used in the next step.

2. In the Project Navigator, click MainApp.swift.

   • In the Editor, add an import statement to reference the API and implement an initializer in the MainApp struct.

   • Set the ArcGISEnvironment.apiKey property with your API key access token.

   MainApp.swift

   import SwiftUI
   
   import ArcGIS
   
   @main
   struct MainApp: App {
   
       init() {
   
           ArcGISEnvironment.apiKey = APIKey("<#YOUR-ACCESS-TOKEN#>")
   
       }
   
       var body: some SwiftUI.Scene {
           WindowGroup {
               ContentView()
   
                   .ignoresSafeArea()
   
           }
       }
   
   }

Best Practice: The access token is stored directly in the code as a convenience for this tutorial. In a production environment we do not recommend that you store it directly in source code.
