iOS Mobile SDK

Introduction

Arkose Labs' mobile SDK lets you wrap our solution with iOS native function calls. This guarantees seamless integration of your mobile apps with Arkose's full interactive challenges on detection and enforcement, and does so without the extended wait times for separate mobile solutions.

This page covers the Mobile SDK for iOS. If you are developing in Android, see the Mobile SDK for Android page.

The Arkose Mobile SDK for iOS v1:

• Wraps Arkose's Advanced Enforcement Challenge in native iOS “web views”.

• Has 1-to-1 feature availability between web and mobile solutions.

• Integrates with your apps through native functions.

• Handles errors through callback events.

• Complies with Arkose Internal Security guidelines.

• Complies with Apple App Store guidelines for ease of integration.

• Is fully compatible with new API releases.

• Supports minimum version iOS 13.0.

Mobile SDK High Level Design

Mobile SDK Builds Availability

The Arkose Labs Mobile SDKs are available via the Mobile SDK’s Support page. Please talk with your CSM (Customer Success Manager) about your intended usage and to request access.

Compatibility

The Arkose Labs Mobile SDK for iOS works with iOS 13.0 and up.

All existing detection and challenge features on our web solution are also available on the Mobile SDKs. All new ones are automatically added; you don't need to update your application every time we have a new release of our Web platform.

Security

The Arkose Labs Mobile SDKs are Arkose Labs Security reviewed and comply with Apple App Store guidelines.

Performance

We created the Arkose Labs Mobile SDKs with stability and performance in mind. Their use has no significant impact on the host application’s performance.

Installation

Follow these steps to set up Arkose Labs Mobile SDK for iOS in Xcode in your host application. This applies to both our detection and enforcement components.

Prerequisites

• A host iOS application. You must be able to build and run this application.

• For the full end-to-end Arkose setup, you must also complete the standard Arkose Server-Side setup instructions.

Integration Steps

Add ArkoseLabsKit to the Project

1. In Xcode, open your Host application.

2. From the Project Navigator area, select the folder with your project’s name.

3. From the project’s xcodeproj details, select Target.

4. To use the dynamic framework:

   1. Scroll to Frameworks, Libraries, and Embedded Content and drag and drop ALSDK.XCFramework into this section.
   2. In the Project Navigator, find the Frameworks folder and verify ArkoseLabsKit is inside it.
   3. Click on Build Phases to display that tab. Find the Link Binary with Libraries section and confirm it contains the ArkoseLabsKit.xcframework.

5. To use the static framework:

   1. Scroll to Frameworks, Libraries, and Embedded Content and drag and drop ArkoseLabsKitStatic.xcframework into this section. (or add it as shown in the video)
   2. In the Project Navigator, find the Frameworks folder and verify ArkoseLabsKitStatic is inside it.
   3. Click on Build Phases to display that tab. Find the Link Binary with Libraries and confirm it contains the ArkoseLabsKitStatic.xcframework.
   4. In the Copy Bundle Resources section, add ArkoseLabsKitResource.Bundle

6. Perform a Clean task.

7. Perform a Build.

Initialize the SDK

To integrate Arkose Bot Manager with the enforce challenge, follow the steps outlined below:

1. Import the ArkoseLabsKit or ArkoseLabsKitStatic module before invoking any API from the SDK:

// For dynamic framework
import ArkoseLabsKit

// For static framework
//import ArkoseLabsKitStatic

2. Initialize the SDK as soon as the application launches with the ArkoseConfig object that contains all configuration parameters. We recommend using the UIApplicationDelegate didFinishLaunchingWithOptions notification to do the initialization. A sample initialization code is shown below:

   Swift

   ArkoseManager.initialize(
       with: ArkoseConfig.Builder(withAPIKey: <SPECIFY_YOUR_API_KEY>)
               .with(language: "en")
               .build()
       )
   

   A complete example of didFinishLaunchingWithOptions implementation is below:

   Swift

   // For dynamic framework
   import ArkoseLabsKit
   
   // For static framework
   //import ArkoseLabsKitStatic
   import SwiftUI
   
   class AppDelegate: NSObject, UIApplicationDelegate {
       func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
           ArkoseManager.initialize(
               with: ArkoseConfig.Builder(withAPIKey: <SPECIFY_YOUR_API_KEY>)
                       .with(language: "en")
                       .build()
               )
           return true
       }
   }
   

Integrate into a SwiftUI Aplication

1. To run Arkose Bot Manager and display the Enforcement Challenge in a SwiftUI View, integrate ArkoseChallengeView into the content of your custom view.

ArkoseChallengeView(isPresented: $isPresented, delegate: self, cancelButtonTitle: "Cancel")

See Appendix: SwiftUI Content View below for a complete example.

Integrate into a UIKit Application

1. To run Arkose Bot Manager and display the Enforcement Challenge from a UIKit ViewController, invoke ArkoseManager.showEnforcementChallenge from an action method.

ArkoseManager.showEnforcementChallenge(
    parent: self,
    delegate: self,
    cancelButtonTitle: "Cancel")

See the Appendix: UIKit View Controller below for a complete example.

Receiving Notifications

To receive notifications about various events triggered by Enforcement Challenge, implement the ArkoseChallengeDelegate protocol on the SwiftUI View or the UIViewController class and pass the instance as the delegate parameter above. To simplify the implementation, ArkoseChallengeDelegate has a default implementation, so implement only the necessary methods for your desired functionality. The most commonly implemented protocol methods are onCompleted, onError, and onFailed to complete the necessary action from the application.

Build the revised project

1. Perform a Clean.
2. Perform a Build.

Run and test the application

1. Run your modified iOS application.
2. If running Arkose Bot Manager:
   1. On the integrated screen, confirm you now see an Arkose Labs Enforcement Challenge.b. Verify the challenge.
   2. On successful verification, the onCompleted event returns a token as part of the response JSON object.
3. Send the token to your back-end server for verification.

Update Configuration in the SDK

To update configuration of the SDK any time before the enforcement challenge is called, follow the steps outlined below:

In SwiftUI Application

1. To run Arkose Bot Manager and display the Enforcement Challenge in a SwiftUI View, integrate ArkoseChallengeView into the content of your custom view.
   Swift

   ArkoseChallengeView(isPresented: $isPresented,
                                       delegate: self,
                                       cancelButtonTitle: "Cancel",
                                       resetButtonTitle: "Reset",
                                       config:
                                           ArkoseConfig.Builder(
                                               withAPIKey: <SPECIFY_YOUR_API_KEY>)
                                               .with(language: "en")
                                               .build())
   

   See Appendix: SwiftUI Content View below for a complete example.

In a UIKit Application

1. To run Arkose Bot Manager and display the Enforcement Challenge from a UIKit ViewController, invoke ArkoseManager.showEnforcementChallenge from an action method.
   Swift

   ArkoseManager.update(with: 
     ArkoseConfig.Builder(
       withAPIKey: <SPECIFY_YOUR_API_KEY>)
       .with(language: "fr")
       .build()
       )
   

See the Appendix: UIKit View Controller below for a complete example.
