# Integrate With iOS Custom SDK

> With Razorpay iOS Custom SDK, you can customise the Razorpay Checkout UI.

Customise the look and feel such as colours and themes of your app's Checkout form.

* Validate customer inputs such as card number, expiry date and others using the [Luhn check algorithm](https://en.wikipedia.org/wiki/Luhn_algorithm).
* Configure and integrate the payment methods on the Checkout form.

<Warning>
  **Watch Out!**

  * [Razorpay iOS Standard SDK](/payments/payment-gateway/ios-integration/standard) supports all payment methods by default. We recommend you integrate with the Razorpay iOS Standard SDK. If you integrate with Custom Checkout SDK, you will need to integrate these manually.
  * This framework only supports iOS version **10.0 and above**.
</Warning>
