The Airwallex iOS SDK is a flexible tool that enables you to integrate payment methods into your iOS app. It provides native UI screens to facilitate payment functions on top of your existing purchase flow. You can also choose to build your own custom UI using API integration.

## User experience

Check out the [user experience](/payments/online-payments/mobile-sdk) to explore the different types of payment processes supported by Airwallex iOS SDK and to view how Airwallex Native UI pages would look like in your app.

## Prerequisites

Before you begin your integration, you need to set up the SDK, complete configuration, and create a `PaymentIntent` on your server. See [Before you start](/payments/online-payments/mobile-sdk/guest-user-checkout/ios-airwallex-sdk/before-you-start) for more details.

## Integration steps

Airwallex iOS SDK supports two integration options:

- [Airwallex Native UI integration](/payments/online-payments/mobile-sdk/guest-user-checkout/ios-airwallex-sdk/native-ui-integration):  Also known as basic integration, this option allows you to integrate Airwallex's pre-built payment pages into your iOS app. This integration types does not require [PCI-DSS](https://www.pcisecuritystandards.org/merchants/) compliance.
- [Airwallex low-level API integration](/payments/online-payments/mobile-sdk/guest-user-checkout/ios-airwallex-sdk/low-level-api-integration):  Allows you to build your own custom UI on top of our low-level APIs.
  - Your app must be __PCI-DSS compliant__ if using [Confirm card payment with card and billing details](/payments/online-payments/mobile-sdk/guest-user-checkout/ios-airwallex-sdk/native-ui-integration/card) flow. Provide a PCI-DSS AOC and renew it regularly.
