Pass your API Key access token to the ArcGISEnvironment.

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

2. Implement an initializer in the MainApp struct and 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#>")
   
       }

Best Practice: The access token is stored directly in the code as a convenience for this tutorial. Do not store credentials directly in source code in a production environment.

Use the Authenticator toolkit component to manage your OAuth credentials OAuth credentials are an item that contains parameters required to implement user authentication or app authentication, including a client_id, client_secret, and redirect URIs. They are a type of developer credential. Learn more and pass it to the ArcGISEnvironment.

1. Add the ArcGIS Maps SDK for Swift Toolkit package to your application by following these instructions.

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

   • Add import ArcGISToolkit into the code.
   • Declare and initialize an Authenticator toolkit component in the MainApp struct.
   • Implement an initializer in the MainApp struct.
   • Create a new instance of the Authenticator using an OAuthUserConfiguration
   • Add your PortalURL, clientID and redirectURL values.
   • Pass the authenticator to the ArcGISEnvironment.authenticationManager to handle any challenges.
   MainApp.swift

   import SwiftUI
   
   import ArcGIS
   
   import ArcGISToolkit
   
   @main
   struct MainApp: App {
   
       @ObservedObject var authenticator: Authenticator
   
       init() {
   
           authenticator = Authenticator(oAuthUserConfigurations: [
               OAuthUserConfiguration(
   
                   portalURL: URL(string: "<#YOUR-PORTAL-URL#>")!,
                   clientID: ""<#YOUR-CLIENT-ID#>"",
                   redirectURL: URL(string: "<#YOUR-REDIRECT-URL#>")!
   
               )
           ])
           ArcGISEnvironment.authenticationManager.handleChallenges(using: authenticator)
   
       }
   • In the body, add an .authenticator(authenticator) modifier to the ContentView.
   MainApp.swift

       var body: some SwiftUI.Scene {
   
           WindowGroup {
               ContentView()
   
                   .authenticator(authenticator)
   
           }
       }

Best Practice: The OAuth credentials are stored directly in the code as a convenience for this tutorial. Do not store credentials directly in source code in a production environment.

Pass your API Key access token to the ArcGISEnvironment.

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

2. Set the AuthenticationMode to .apiKey.

   MainApp.swift

       // Change the `AuthenticationMode` to `.apiKey` if your application uses API key authentication.
   
       private var authenticationMode: AuthenticationMode { .apiKey }

3. Set the apiKey property with your API key access token.
