# CrossmintCheckoutController

> Swift Class

**Class**

The observable order state of one embedded checkout session.

```swift theme={null}
@MainActor final class CrossmintCheckoutController
```

Give an instance to `CrossmintEmbeddedCheckout`. Observe the instance to react to order changes. `identityVerificationCredentials` has a value when the order needs identity verification. Call `clear()` before you use one controller for a new checkout session.

## Initializers

### init()

Creates a controller with no order.

```swift theme={null}
@MainActor init()
```
