Guide for integrating Kvalifika SDK into a Swift project

Use Kvalifika SDK to easily integrate into your Android app. Before integrating Kvalifika, 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 Kvalifika

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() {
print("onInitialize")
}
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 Kvalifika 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")
}
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.

COMPARE_IMAGES_FAILED

Could not compare images. Internal request failed.

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

English

GE

Georgian

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