SDK Lifecycle

CafFaceLivenessDelegate

The CafFaceLivenessDelegate protocol handles key events during the SDK's liveness detection process:

Event	Description
cancelled()	Triggered when the user cancels the process.
didFinishWithError(sdkFailure: CafSDKFailure)	Called on SDK failure, with error details provided in sdkFailure.
loaded()	Triggered when the SDK is ready, if the loading screen is disabled.
loading()	Indicates the SDK is initializing, called if no loading screen is shown.
didFinishWithSuccess(livenessResult: CafLivenessResult)	Called upon successful detection, with the result in livenessResult.signedResponse.

Example

extension YourViewController: CafFaceLivenessDelegate {
    func didFinishWithSuccess(livenessResult: CafLivenessResult) {
        print("Success: \(livenessResult.signedResponse ?? "No response")")
    }

    func cancelled() {
        print("Liveness detection cancelled")
    }

    func didFinishWithError(sdkFailure: CafSDKFailure) {
        print("Error: \(sdkFailure.description ?? "Unknown error")")
    }

    func loading() {
        print("Liveness detection loading")
    }

    func loaded() {
        print("Liveness detection loaded")
    }
}
