Xcode Supported Version

IDWise SDK always supports latest Xcode version only. The current latest release of IDWise SDK (IDWise 3.9.2) supports below Xcode version.



The minimum deployment target for IDWiseSDK is iOS 12.0. In order to use the SDK your application minimum deployment target should be iOS 12.0 or higher. On your development machine you need to have XCode and CocoaPods installed. Both Intel and M1 (Apple Sillicon) based machines are supported. When working with Cocoapods you might have to run some commands through Rosetta Stone compatibility mode.

Step 1: Installation

IDWiseSDK is available to install via CocoaPods package manager from IDWise private Cocoapods repository. IDWise is a dynamic framework and requires the podfile to use use_frameworks! directive to be used so dynamic pods/frameworks can install and run successfully.

React Native’s native iOS dependencies are compiled as static libraries and many react-native node modules are only ever compiled and tested as static libraries. When trying to incorporate a dynamic framework (which Swift dependencies are often bundled as), compilation problems often ensue.

As aforementioned, Cocoapods builds pods by default as static libraries. To use a framework like this we normally use the use_frameworks! Cocoapods directive at the top of our Podfile. However, this causes ALL pods to be compiled as dynamic frameworks. Not only will some React Native pods fail, but a large number of 3rd party React Native libraries will as well.

If you can find a way where you can use use_frameworks! directive and still able to install IDWise pod and other React Native native iOS dependecies (Flipper, Folly, YogaKit etc) and successfully run the react native project then It’s fine. Otherwise, the workaround is to use a plugin over cocoapods which can dynamically install specific libraries as static or dynamic during pod installation process.

You can use this plugin to install pods which enables us to dictate the specific build type of a pod ( dynamic in our case ). You can go through the README section of this plugin as well. We can easily install this plugin by typing this command in our terminal gem install cocoapods-user-defined-build-types. It will install this plugin over our cocoapods. You can use our sample project’s podfile in which we used this plugin for IDWise pod’s dynamic installation.

Without cocoapods-user-defined-build-types Plugin

To add IDWise SDK to your project, first ensure you have these two lines at the top of your Podfile file:

source ''
source ''

In this case, you should use use_frameworks! directive in your podfile.

This adds IDWise private Cocoapods repository as a source to install packages from

Next add this line also to your Podfile but this time underneath your target node for your project:

pod 'IDWise'

Also, add this configuration underneath your target node for your project:

  post_install do |installer|
    installer.pods_project.build_configurations.each do |config|
      config.build_settings['CODE_SIGNING_ALLOWED'] = 'NO'

After adding our dependency in your Podfile run:

pod install

With cocoapods-user-defined-build-types Plugin

To add IDWise SDK to your project, first ensure you have these two lines at the top of your Podfile file:

source ''
source ''
plugin 'cocoapods-user-defined-build-types', {
  verbose: true

This adds IDWise private Cocoapods repository as a source to install packages from

Next add this line also to your Podfile but this time underneath your target node for your project:

 pod 'IDWise', :build_type => :dynamic_framework

You can have a look at the example Podfile provided in the ios folder of this repository to see an example Podfile with both the changes above completed

After adding our dependency in your Podfile run:

pod install

Step 2: Linking

In order to Link the React Code with iOS, we need to create a swift class with objective-c bridging, let’s call it IDWiseModule. You can find the sample [IDWiseModule.swift] ( for sample code.This class will act as a bridge between swift and react native, because react native’s ios bridging code is written in objectve-c so we have to mark our swift class with @objc annotation.

We also need to create a header (.h) and an implementation file (.m) for our swift class with same name as our swift class. In header file, we do some native module imports and in implementation file we export our swift class and It’s method’s as module and method’s respectively. You can find the sample of both of these files [IDWiseModule.h,IDWiseModule.h] at ( and ( respectively.

Step 3: React-Native Usage

Invoking IDWise SDK is very simple. First reterieve IDWiseModule from NativeModules in your .js file from where you want to invoke IDWise SDK:

const { IDWiseModule } = NativeModules;

Initializing the SDK

In order to use the SDK, we need to initialize it first with the <CLIENT_KEY> provided by IDWise and a theme parameter. You can pre-load this on componentDidMount() if you want to. Here is how we can initialize the SDK.

IDWiseModule.initialize("<CLIENT_KEY>", theme);

Starting the Journey

Now we can start the verfication journey by calling startJourney(..) of the SDK like below. This will start the verification process and that’s it.


Starting the Steps

When onJourneyStarted(...) or onJourneyResumed(...) is triggered successfuly, you can call the IDWise.startStep(...) to start the specific verfication Step. IDWise.startStep takes the following parameters:

  • stepId: ID of the step you want to start. (Will be provided by IDWise for each step)

Here is the sample implementation of starting a step


The above code will show IDWise UI to take the user through capturing the step from the camera.

Instead of using the camera to capture, you can also pass a file directly as a ByteArray. Supported file formats are JPG, PNG or PDF.

Important Note: Size of the byteArray should be less then 6MB. Following is an example


The step events (stepCaptured and stepResult) will be triggered the step is handled and processed.

Resuming the Journey

We can resume the verfication journey by calling resumeDynamicJourney(..) of the SDK like below. This will resume the verification process.

IDWiseModule.resumeDynamicJourney("<JOURNEY_DEFINITION_ID>", "<JOURNEY_ID>", "en");

Events (Callbacks)

Throughout the journey, IDWise SDK sends back some events to your app. Here are examples how to listen to these events:

These are the supported events:

  • onJourneyStarted: Triggered when the journey is started and the Journey ID is assigned.
  • onJourneyFinished: Triggered when the journey is completed by the user.
  • onJourneyCancelled: Triggered when the user cancels the journey and doesn’t finish it.
  • onJourneySummary: Triggered as the callback response for the journey summary.
  • onError: Triggered when an error occurs for example a network connectivity error and lack of permission to access the camera.
  • onStepCaptured: Triggered after capturing the image from the camera for a step.
  • onStepResult: Triggered after the backend processing of a step is competed.

useEffect(() => {
  const eventEmitter = new NativeEventEmitter(NativeModules.IDWiseModule);

  eventEmitter.addListener("onError", (event) => {
      `An Error has occured  ${event.errorCode} : ${event.errorMessage}`

  eventEmitter.addListener("onJourneyStarted", (event) => {
    console.log(`Journey Started with id ${event.journeyId}`);

  eventEmitter.addListener('onJourneyResumed', event => {
    console.log(`Journey Resumed with id ${event.journeyId}`);

  eventEmitter.addListener("onJourneyFinished", (event) => {
    console.log(`Journey Completed with id ${event.journeyId}`);

  eventEmitter.addListener("onJourneyCancelled", (event) => {
    console.log(`Journey Cancelled with id ${event.journeyId}`);

  eventEmitter.addListener('onJourneySummary', event => {
    console.log(`Journey Summary for id ${event.journeyId}`);
    console.log(`Journey Step Summaries ${event.journeyStepSummaries}`);
    console.log(`Journey Result ${event.journeyResult}`);
    console.log(`Journey Is Complete ${event.journeyIsComplete}`);

  eventEmitter.addListener('onStepCaptured', event => {
      console.log(`Step Captured with id ${event.stepId}`);
      console.log(`Step Captured Bitmap Base64 ${event.bitmapBase64}`);

  eventEmitter.addListener('onStepResult', event => {
    console.log(`Step Result with id ${event.stepId} : ${event.stepResult}`);
}, []);

Get Summary of the Verification Journey

You can get the Status of the journey anytime by calling the following function. You will receive the response against onJourneySummary event having the fields journeyId, journeyStepSummaries, journeyResult and journeyIsComplete.
