# Stytch iOS B2B SDK Overview

> Get started with the Stytch iOS B2B SDK for building secure authentication flows for business applications

<Note>These docs are for our new Kotlin Multiplatform SDK, which is in **Public beta**. If you are instead looking for the stable version, please see [stytch-ios](https://github.com/stytchauth/stytch-ios) and the usage docs [here](https://stytchauth.github.io/stytch-ios/latest/StytchCore/documentation/stytchcore/).</Note>

The Stytch SDKs provide methods that communicate directly with the Stytch API, allowing you to easily authenticate your users without adding extra endpoints to your backend.

The Stytch iOS B2B SDK is a headless Kotlin Multiplatform library distributed as a Swift package. It provides a Swift-native async/await API for all Stytch B2B authentication methods including SSO, SCIM provisioning, and multi-org discovery, with idiomatic Swift wrappers generated by [SKIE](https://skie.touchlab.co/).
