            let portalItem = PortalItem(portal: .arcGISOnline(connection: .anonymous), id: portalID)
            return Scene(item: portalItem)
    
        }()
    

Run the solution

Press Command + R to run the app.

Your app should display the scene that you viewed earlier in the Scene Viewer. You should see a map of trails, trailheads and parks in the Santa Monica Mountains. Drag, pinch, and rotate on the scene view to explore the scene.

Alternatively, you can download the tutorial solution, as follows.

Option 2: Download the solution

  1. Click the Download solution link under Solution and unzip the file to a location on your machine.

  2. Open the .xcodeproj file in Xcode.

Since the downloaded solution does not contain authentication credentials, you must first set up authentication to create credentials, and then add the developer credentials to the solution.

Set up authentication

To access the secure used in this tutorial, you must implement or using an or an account.

Create a new API key with to access the secure resources used in this tutorial.

  1. Complete the Create an API key tutorial and create an API key with the following :

    • Privileges
      • Location services > Basemaps
  2. Copy and paste the API Key access token into a safe location. It will be used in a later step.

Set developer credentials in the solution

To allow your app users to access , pass the developer credentials that you created in the Set up authentication step to the application's ArcGISEnvironment.

Pass your API Key access token to the ArcGISEnvironment.

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

  2. Set the AuthenticationMode to .apiKey.

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.

Run the solution

Press Command + R to run the app.

Your app should display the scene that you viewed earlier in the Scene Viewer. You should see a map of trails, trailheads and parks in the Santa Monica Mountains. Drag, pinch, and rotate on the scene view to explore the scene.
