Guide for integrating Cactusverify SDK into a Swift project

Use Cactusverify SDK to easily integrate into your Android app. Before integrating Cactusverify, it is recommended to follow the steps described in Integration Guide and Initial Setup.

Naming of the properties and functions might be slightly modified depending on the version.

Installation

Add the following to the project's main Podfile file:

source 'https://github.com/CocoaPods/Specs.git'
source 'https://github.com/Kvalifika/kvalifika-cocoapods-specs.git'
source 'https://github.com/Kvalifika/zoom-cocoapods-specs.git'

platform :ios, '11.0'

# Your Target
target 'kvalifika-swift-sample' do
  use_frameworks!

  pod 'Kvalifika'
end

If you want to update pod run in terminal:

pod update Kvalifika

Initialize the SDK

import Cactusverify

After that, you need to initialize SDK with your appId.

appId is Application ID, generated from Admin Panel. See Initial Setup for details.

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()

        // Initialize SDK and provide names of images
        KvalifikaSDK.initialize(
            AppID: "YOUR APP ID",
            Locale:  KvalifikaSDKLocale.GE.rawValue,
            Logo: "AppLogo",
            DocumentIcon: "DocLogo",
            CancelIcon: "cancel",
            ActiveFlashIcon: "",
            InactiveFlashIcon: "",
            onInitialize: onInitialize,
            onStart: onStart,
            onFinish: onFinish,
            onError: onError
        )
    }

    func onInitialize() {
        // Start session right after initialization
        let _ = KvalifikaSDK.startSession(onViewController: self)
    }

    func onStart(sessionId: String) {
        print("onStart")
    }

    func onFinish(sessionId: String) {
        print("onFinish")
    }

    func onError(error: KvalifikaSDKError) {
        print(error)
    }
}

App Permissions

Please add the following permissions to your app's Info.plist, so that the Cactusverify iOS SDK can access a user's camera to run a verification. You can do this in the property list view or by code. Right-click on Info.plist and select Open As -> Source Code. Add the lines below somewhere inside the file <dict> </dict>

<!-- permission strings to be include in info.plist -->
<key>NSCameraUsageDescription</key>
<string>Please give us access to your camera, to complete the verification.</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>Please give us access to your photo library to verify you.</string>

Start Verification

Call Kvalifika.startSession() on button click event

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()

        // Initialize SDK
        KvalifikaSDK.initialize(
            AppID: "YOUR APP ID",
            Locale:  KvalifikaSDKLocale.GE.rawValue,
            Logo: "AppLogo",
            DocumentIcon: "DocLogo",
            CancelIcon: "cancel",
            ActiveFlashIcon: "",
            InactiveFlashIcon: "",
            onInitialize: onInitialize,
            onStart: onStart,
            onFinish: onFinish,
            onError: onError
        )
    }

    func onInitialize() {
        print("onInitialize")
    }

    func onStart(sessionId: String) {
        print("onStart")
    }

    func onFinish(sessionId: String) {
        print("onFinish")
    }

    func onError(error: KvalifikaSDKError) {
        print(error)
    }

    @IBAction func onStart(_ sender: Any) {
        let _ = KvalifikaSDK.startSession(onViewController: self)
    }
}

Handling Verifications

It's useful to know that whether a user has completed the verification flow or canceled it. For this, you can implement the callback methods.

Callback Methods

Method	Description
onInitialize	This callback method is triggered when SDK is initialized.
onStart	This callback method is triggered when the user starts verification.
onFinish	This callback method is triggered when the user completes verification. Get session data here.
onError	This callback method is triggered on error (see Error Codes for more information)

    func onInitialize() {
        print("onInitialize")
        // Start session right after initialization
        let _ = KvalifikaSDK.startSession(onViewController: self)
    }

    func onStart(sessionId: String) {
        print("onStart")
    }

    func onFinish(sessionId: String) {
        // Fetch session data here from your server
        print("onFinish")
    }

    func onError(error: KvalifikaSDKError) {
        print(error)
    }

Error Codes

Error Code	Description
INVALID_APP_ID	Kvalifika App Id is incorrect
USER_CANCELLED	User canceled before completing verification.
TIMEOUT	Canceled due to inactivity.
SESSION_UNSUCCESSFUL	The Session was not performed successfully
ID_UNSUCCESSFUL	The ID Scan was not performed successfully and identity document data was not generated.
CAMERA_PERMISSION_DENIED	Camera is required but access is prevented by user settings.
LANDSCAPE_MODE_NOT_ALLOWED	Verification was canceled because the device is in landscape mode.
REVERSE_PORTRAIT_NOT_ALLOWED	Verification was canceled because the device is in reverse portrait mode.
FACE_IMAGES_UPLOAD_FAILED	Could not upload face images. Internal request failed.
DOCUMENT_IMAGES_UPLOAD_FAILED	Could not upload ID card or passport images. Internal request failed.
NO_MORE_ATTEMPTS	User has reached maximum limit of attempts
UNKNOWN_INTERNAL_ERROR	Session failed because of an unhandled internal error.

UI Customizations

Appearance

It is possible to customize the logo and icons and provide resource names.

KvalifikaSDK.initialize(
    Logo: "AppLogo",
    DocumentIcon: "DocLogo",
    CancelIcon: "cancel",
    ActiveFlashIcon: "",
    InactiveFlashIcon: "",
)

Language

It is possible to set locale when initializing SDK. Supported locales are:

Code	Language
EN	English
GE	Georgian
RU	Russian
SP	Spanish

sdk = KvalifikaSDK.initialize(
    Locale: KvalifikaSDKLocale.EN.rawValue
)

Development Mode

Without specifying mode SDK uses https://api.kvalifika.com

With development mode ON SDK uses https://apistaging.kvalifika.com

KvalifikaSDK.initialize(
   AppID: "YOUR APP ID"
   Development: true
)
