# iOS initialization

> Invoke Alignet SDK v2.2 with Swift and process its delegate.

## Import the SDK

```swift theme={"system"}
import Payme
```

## Create and invoke the client

```swift theme={"system"}
let person = PaymePersonData(
    firstName: "Ana",
    lastName: "Perez",
    email: "ana@example.com",
    addrLine1: "123 Main Avenue",
    addrLine2: "",
    countryCode: "PE",
    countryNumber: "604",
    zip: "15000",
    city: "Lima",
    state: "Lima",
    mobilePhone: "51-999999999"
)

let request = PaymeRequest(
    merchant: PaymeMerchantData(
        operation: PaymeOperationData(
            operationNumber: "000001",
            operationDescription: "Purchase",
            amount: "10.55",
            currency: PaymeCurrencyData(code: "604", symbol: "S/")
        ),
        addrMatch: true,
        billing: person,
        shipping: person
    ),
    setting: PaymeSettingData(
        locale: "en_US",
        brands: ["VISA", "MSCD", "AMEX", "DINC"]
    )
)

let client = PaymeClient(delegate: self, key: "COMMERCE_KEY")
client.setEnvironment(environment: PaymeEnviroment.development)
client.authorizeTransaction(
    controller: navigationController!,
    usePresent: false,
    paymeRequest: request
)
```

`usePresent: true` presents the flow modally; `false` uses the `navigationController`.

## Implement the delegate

```swift theme={"system"}
extension PaymentController: PaymeClientDelegate {
    func onNotificate(action: PaymeInternalAction) {
        // Flow telemetry: scoring, 3DS, and authorization.
    }

    func onRespondsPayme(response: PaymeResponse) {
        if response.success, response.payment?.accepted == true {
            // Confirm the order using operationNumber.
        } else {
            // Process resultCode, resultMessage, and resultDetail.
        }
    }
}
```

<Warning>
  Keep a client reference during the flow, do not log sensitive data, and switch to production only with the Key approved for that environment.
</Warning>
