# iOS

Integrate the 1Kosmos SDK into your native iOS app to add identity verification and passwordless authentication.

The iOS SDK provides authentication (PIN, device biometrics, LiveID), document scanning and verification, user onboarding, and passkey support, integrated into your iOS app via Swift Package Manager.

### Requirements

* **OS**: iOS 16.0 or later
* **Tools**: Xcode 26.0.1 (17A400) or higher
* **Language**: Swift 5.9 or higher
* **Dependency management**: Swift Package Manager (supported from SDK v1.30.40)
* **Devices**: iPhone SE (1st, 2nd, and 3rd generations), iPhone 6s or later, iPod Touch (7th generation) or later
* **Simulator**: arm64 or x86\_64 simulators (supported from SDK v1.30.50)

### What's in this section

* **Integration Guide**: step-by-step instructions to install the SDK via Swift Package Manager, initialize it, and implement each feature in a new or existing iOS project.
* **API Reference**: reference documentation for the SDK's classes and error handling, for when you need method-level details.

### Where to start

Start with the Integration Guide to set up and initialize the SDK. Use the API Reference while implementing specific features.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.1kosmos.com/mobile-sdk/native/ios.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
