Add the following code to your app:

```swift
    func application(
        _ application: UIApplication,
        didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
    ) -> Bool {
        try! Amplify.add(plugin: AWSCognitoAuthPlugin())
        try! Amplify.add(plugin: AWSAPIPlugin())
        try! Amplify.configure()
        print("Amplify initialized")

        return true
    }
```
