<Info>
  **New Swift SDK Available**

  It is recommended to use the new [Swift SDK](/guides/payments/native/overview) for native iOS development. It provides native 3DS support, improved performance, and a modern API. This iOS SDK (Embed-based) is still supported and maintained for web view implementations.

In this quick start guide, you are taken through the following steps.

1. [Create an API key](/guides/payments/ios/quick-start/key) which is needed to generate
   the signed JWT token in step 2.
2. [Set up a server-side SDK](/guides/payments/ios/quick-start/sdks) to generate a client
   token for authenticating to the API.
3. [Install the iOS SDK](/guides/payments/ios/quick-start/ios) which handles the
   capture of the payment method details and process the payment.
4. [Process the transaction](/guides/payments/ios/quick-start/transact) and inspect the result.
