assistant: Here is a basic example of what a SwiftUI checkout form with credit card fields could look like:

```
import SwiftUI

struct CheckoutFormView: View {
    @State private var cardNumber = ""
    @State private var expiryDate = ""
    @State private var cvv = ""
    @State private var nameOnCard = ""

    var body: some View {
        VStack {
            Text("Credit Card Information")
                .font(.headline)
                .padding()

            TextField("Card Number", text: $cardNumber)
                .textFieldStyle(RoundedBorderTextFieldStyle())
                .padding()

            HStack {
                TextField("MM/YY", text: $expiryDate)
                    .textFieldStyle(RoundedBorderTextFieldStyle())
                    .padding(.trailing, 10)

                TextField("CVV", text: $cvv)
                    .textFieldStyle(RoundedBorderTextFieldStyle())
                    .padding(.leading, 10)
            }

            TextField("Name on Card", text: $nameOnCard)
                .textFieldStyle(RoundedBorderTextFieldStyle())
                .padding()

            Button(action: {
                // TODO: Implement payment processing
            }) {
                Text("Place Order")
            }
            .padding()
        }
    }
}

struct CheckoutFormView_Previews: PreviewProvider {
    static var previews: some View {
        CheckoutFormView()
    }
}
```

This basic form includes fields for credit card number, expiry date, CVV, and name on card. It also includes a button to submit the order, although the payment processing functionality has not been implemented.

You can add autocomplete modifiers by using the autocapitalization and autocorrection modifiers on the TextField views. For example, you can add autocapitalization(.none) to the card number field to prevent auto-capitalization and autocorrection(.no) to the cvv field to prevent auto-correction.

To implement autofill for shipping and billing addresses, you can use the textContentType modifier on the TextField views. For example, you can add textContentType(.streetAddressLine1) to the shipping address field to suggest previously saved street addresses. You can also use the secureField modifier instead of textField for sensitive information like the CVV.

Remember to add validation and error messages to ensure that the form is filled out correctly and to provide a great user experience. Additionally, consider adding a progress indicator or loading animation to indicate that the order is being processed.
