iOS SDK

This documentation provides a comprehensive guide to integrating the Youverify Liveness iOS and Document Capture SDKs into your mobile applications. These SDKs enable real-time liveness detection to verify that users are physically present as well the capture of users document for real-time information extraction and verification. Two versions of our Liveness SDKs are available to suit different iOS versions and development frameworks:

• YouverifyLivenessSDK: The recommended version, built with SwiftUI, requiring a minimum of iOS 14. Supports both Passive and Active Liveness.

• YouverifyLivenessSDKCompat: The compatibility version, built with UIKit, requiring a minimum of iOS 12. Supports only Active Liveness.

Choosing the Right SDK

Select the SDK that best fits your application's needs based on iOS version support and framework:

Feature	YouverifyLivenessSDK	YouverifyLivenessSDKCompat	YouverifyDocumentCaptureSDK
Minimum iOS Version	iOS 14	iOS 12	iOS 15
Framework	SwiftUI	UIKit	SwiftUi/UIKit
Passive Liveness	Supported (iOS 15+)	Not supported	N/A
Active Liveness	Supported	Supported	N/A
Recommended for	Modern apps using SwiftUI	Legacy apps using UIKit	Both SwiftUI and UIKit

• Passive Liveness: Detects liveness without user interaction (e.g., blinking, skin texture analysis). Available only in YouverifyLivenessSDK.

• Active Liveness: Requires users to perform actions (e.g., head movements, answering questions). Supported in both SDKs, with minimum iOS requirements as specified.

Note: If targeting iOS 14 with YouverifyLivenessSDK, only Active Liveness is available; Passive Liveness requires iOS 15+.
