# Adding SDK to a Client’s Mobile App

## CocoaPods

To integrate OZLivenessSDK into an Xcode project via the [CocoaPods](https://cocoapods.org/) dependency manager, add the following code to Podfile:

```swift
pod 'OZLivenessSDK', :git => 'https://gitlab.com/oz-forensics/oz-liveness-ios', :tag => 'VERSION'
```

Version is optional as, by default, the newest version is integrated. However, if necessary, you can find the older version number in [Changelog](https://doc.ozforensics.com/oz-knowledge/guides/developer-guide/sdk/oz-mobile-sdk/ios/changelog).

Since 8.1.0, you can also use a simpler code:

```swift
// for the latest version
pod ‘OZLivenessSDK’
// OR, for the specific version
// pod ‘OZLivenessSDK’, ‘8.22.0’
```

By default, the full version is being installed. It contains both server-based and on-device analysis modes. To install the server-based version only, use the following code:

```swift
pod 'OZLivenessSDK/Core', :git => 'https://gitlab.com/oz-forensics/oz-liveness-ios.git',  :tag => 'VERSION'
```

For 8.1.0 and higher:

```swift
pod ‘OZLivenessSDK/Core’
// OR
// pod ‘OZLivenessSDK/Core’, ‘8.22.0’
```

## SPM

Please note: installation via SPM is available for versions 8.7.0 and above.

Add the following package dependencies via SPM: <https://gitlab.com/oz-forensics/oz-mobile-ios-sdk> (if you need a guide on adding the package dependencies, please refer to the [Apple documentation](https://developer.apple.com/documentation/xcode/adding-package-dependencies-to-your-app)). **OzLivenessSDK** is mandatory. If you don't need the on-device analyses, skip the **OzLivenessSDKOnDevice** file.

## Manual Installation

You can also add the necessary frameworks to your project manually.&#x20;

1. Download the SDK files from [here](https://gitlab.com/oz-forensics/oz-liveness-ios) and add them to your project.

* **OZLivenessSDK.xcframework**,&#x20;
* **OZLivenessSDKResources.bundle**,
* **OZLivenessSDKOnDeviceResources.bundle** (if you don't need the on-device analyses, skip this file)**.**

2. Download the TensorFlow framework 2.11 from [here](https://github.com/tensorflow/tensorflow/releases).
3. Make sure that:

* both **xcframework** are in **Target-Build Phases -> Link Binary With Libraries** and **Target-General -> Frameworks, Libraries, and Embedded Context**;
* the **bundle** file(s) are in **Target-Build Phases -> Copy Bundle Resources**.
