Getting Started

To set up a partnership, reach out to [email protected]. A clientIdentifier must be provided during onboarding before using the SDK.

Installation

Swift Package Manager

1. Open Xcode.
2. Navigate to File->Add Packages.
3. Add package https://github.com/clearsecureidentity/clear-ios-sdk.git.
4. Select a dependency rule. Up to Next Major Version is recommended.
5. Select Add Package.
6. Ensure Clear is selected and added to the correct target.
7. Select Add Package again.

Manual

1. Navigate to releases.
2. Select the latest version.
3. Download Clear.xcframework.zip.
4. Unzip the framework.
5. Add the framework to your Xcode project. Be sure to check Copy items if needed.
6. Ensure the framework is visible in Build Phases->Link Binary With Libraries.
7. Add the framework to Build Phases->Embed Frameworks.

Usage

1. Import the Module

import Clear

2. Initialize the Root Class

CLEAR is the root class of the SDK. An application must initialize this using a CLEAR.Configuration struct before using any functionality. This will usually happen in AppDelegate or SceneDelegate. The struct contains the following required values:

• environment: Set to integration while onboarding. Change to production after proper functionality is verified.
• clientIdentifier: A client specific value given during onboarding.
• scope: A space-delimited string of all desired user properties.

Optional Values:

• callbackScheme: Defaults to the bundle identifier of the client application. In most cases this will not change. When supplying a custom value, ://auth is appended automatically.

// Initialize using an example scope.
let configuration = CLEAR.Configuration(environment: .integration, clientIdentifier: "my-client-id", scope: "email given_name")
CLEAR.initialize(with: configuration)

3. Create a VerificationView

VerificationView is a UI component that triggers the web verification process when tapped.

// Initialize VerificationView from inside a view controller.
let verificationView = VerificationView(delegate: self)
view.addSubview(verificationView)

4. Conform to VerificationDelegate

VerificationDelegate provides additional configuration details, and sends back the result of verification.

extension ViewController: VerificationDelegate {

    /// The view controller that will launch the verification process.
    var hostViewController: UIViewController { self }

    /// Called when the verification process is complete.
    func verificationDidComplete(withResult result: Result<CLEAR.Response, CLEAR.Error>) {

        switch result {
        // Handle a successful result accordingly.
        case .success(let result): print(result.authorizationCode)
        // Handle a unsuccessful result accordingly.
        case .failure(let error): print(error.errorDescription)
        }
    }
}

Result

Successful Verification

After a successful verification, a CLEAR.Response struct is returned in the verificationDidComplete(withResult:) delegate method. This struct contains an authorizationCode, which can be used to request additional information about a CLEAR member.

Unsuccessful Verification

After an unsuccessful verification, a CLEAR.Error enum is returned in the verificationDidComplete(withResult:) delegate method. This enum contains one of the possible error cases:

• cancelled: The operation was cancelled.

• invalidVerificationPath: The configuration is invalid.

• missingHostViewController: A hostViewController must be supplied.

• stateGenerationFailed: Failed to generate a state value.

• sessionFailed: Something has gone wrong with the session.

• missingRedirectResponse: No redirect URL was found in the response.

• missingAuthorizationCode: The authorization code was not found.

• stateIntegrityFailed: There was an internal state integrity error.

• unknown: An unexpected error occurred.
