Zendesk offers a range of Software Development Kits, commonly abbreviated to SDKs. These SDKs allow you to bring support features to your end-users in your apps.

The range consists of the following SDKs:

This SDK: The Chat SDK for iOS

The Chat SDK for iOS is a quick and convenient way to embed chat in your app and make chat with your support agents a breeze for your customers. The Chat SDK is fully native so you don't have to deal with ugly web views or complicated flows.

Integrating chat into a new or existing project takes only a few lines of code. The Chat SDK combines this simplicity with the flexibility to make the chat interface look and feel like the rest of your app.

To give other support options to your customers, see the Zendesk Support SDK. The Support SDK includes Help Center, ticketing, and app ratings and feedback. Though the Chat and Support SDKs are separate SDKs, you can use one or both in a single app to provide the support options you want.
