OwnID Gigya-iOS SDK

The OwnID Gigya-iOS SDK integrates with Email/Password-based Gigya Authentication for apps that do not use Screen-Sets. If your app uses Gigya Screen-Sets, you should use the OwnID Gigya-Screen-Sets iOS SDK instead. For instructions, see the Gigya-Screen-Sets guide.

The OwnID Gigya-iOS SDK is a client library written in Swift that provides a passwordless login alternative for your iOS application by using cryptographic keys to replace the traditional password. Integrating the SDK with your iOS app adds a Skip Password option to its registration and login screens. For more general information about OwnID SDKs, see OwnID iOS SDK.

Before You Begin

Before incorporating OwnID into your iOS app, you must create an OwnID application and integrate it with your Gigya project. For step-by-step instructions, see OwnID-Gigya Integration Basics.

In addition, ensure you have done everything to add Gigya authentication to your iOS project.

Add Package Dependency

The OwnID iOS SDK is distributed as an SPM package. Use the Swift Package Manager to add the following package dependency to your project:

https://github.com/OwnID/ownid-ios-sdk

When prompted, select the OwnIDGigyaSDK product.

Add Property List File to Project

When the application starts, the OwnID SDK automatically reads OwnIDConfiguration.plist from the file system to configure the default instance that is created. At a minimum, this PLIST file defines a redirection URI and unique app id. Create OwnIDConfiguration.plist and define the following mandatory parameters:

Complete example

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>OwnIDRedirectionURL</key>
	<string>com.myapp.demo://bazco</string>
	<key>OwnIDAppID</key>
	<string>4tb9nt6iaur0zv</string>
</dict>
</plist>

Where:

  • The OwnIDAppID is the unique AppID, which you can obtain from the OwnID Console.
  • The OwnIDRedirectionURL is the full redirection URL, including its custom scheme. This URL custom scheme must match the one that you defined in your target.

Create URL Type (Custom URL Scheme)

You need to open your project and create a new URL type that corresponds to the redirection URL specified in OwnIDConfiguration.plist. In Xcode, go to Info > URL Types, and then use the URL Schemes field to specify the redirection URL. For example, if the value of the OwnIDRedirectionURL key is com.myapp.demo://bazco, then you could copy com.myapp.demo and paste it into the URL Schemes field.

Import OwnID Module

Once you have added the OwnID package dependency, you need to import the OwnID module so you can access the SDK features. As you implement OwnID in your project, add the following to your source files:

Complete example

import OwnIDGigyaSDK

Initialize the SDK

The OwnID SDK must be initialized properly using the configure() function, preferably in the main entry point of your app (in the @main App struct). For example, enter:

Complete example

@main
struct ExampleApp: App {
    init() {
        OwnID.GigyaSDK.configure()
    }
}

If you did not follow the recommendation for creating the OwnIDConfiguration.plist file, you need to specify arguments when calling the configure function. For details, see Alternative Syntax for Configure Function.

Implement the Registration Screen

Within a Model-View-ViewModel (MVVM) architecture pattern, adding the Skip Password option to your registration screen is as easy as adding an OwnID view model and subscription to your app's ViewModel layer, then adding the OwnID view to your main View. That's it! When the user selects Skip Password, your app waits for events while the user interacts with the OwnID Web App, then calls a function to register the user once they have completed the Skip Password process.

Important: When a user registers with OwnID, a random password is generated and set for the user's Gigya account.

Customize View Model

The OwnID view that inserts the Skip Password UI is bound to an instance of the OwnID view model. Before modifying your View layer, create an instance of this view model, OwnID.FlowsSDK.RegisterView.ViewModel, within your ViewModel layer:

Complete example

final class MyRegisterViewModel: ObservableObject {
    // MARK: OwnID
    let ownIDViewModel = OwnID.GigyaSDK.registrationViewModel(instance: <Your Instance Of Gigya>)
}

After creating this OwnID view model, your View Model layer should listen to events from the OwnID Event Publisher, which allows your app to know what actions to take based on the user's interaction with the OwnID Web App. Simply add the following to your existing ViewModel layer to subscribe to the OwnID Event Publisher and respond to events (it can be placed just after the code that creates the OwnID view model instance).

Complete example Complete example

final class MyRegisterViewModel: ObservableObject {
    // MARK: OwnID
    let ownIDViewModel = OwnID.GigyaSDK.registrationViewModel(instance: <Your Instance Of Gigya>)

    init() {
     subscribe(to: ownIDViewModel.eventPublisher)
    }

     func subscribe(to eventsPublisher: OwnID.RegistrationPublisher) {
       eventsPublisher
           .receive(on: DispatchQueue.main)
           .sink { [unowned self] event in
               switch event {
               case .success(let event):
                   switch event {
                   // Event when user successfully
                   // finishes Skip Password
                   // in OwnID Web App
                   case .readyToRegister:
                     // If needed, ask user to enter
                     // email (mandatory) and call
                     // OwnID.FlowsSDK.RegisterView.ViewModel.
                     // register(with email: String)
                     // to finish registration.
                     // To pass additional parameters,
                     // such as first name, use
                     // the same approach as in Gigya
                     let nameValue = "{ \"firstName\": \"\(firstName)\" }"
                     let paramsDict = ["profile": nameValue]
                     let params: OwnID.GigyaSDK.GigyaRegisterParameters(parameters: paramsDict)
                     ownIDViewModel.register(with: email, registerParameters: params)

                   // Event when OwnID creates Gigya
                   // account and logs in user
                   case .userRegisteredAndLoggedIn:
                     // User is registered and logged in with OwnID

                   case .loading:
                     // Display loading indicator according to your designs
                   }

               case .failure(let error):
                // Handle OwnID.CoreSDK.Error here
                // For an example of handling an interruption,
                // see Errors section of this doc
               }
           }
           .store(in: &bag)
   }
}

Important: The OwnID ownIDViewModel.register function must be called in response to the .readyToRegister event. This ownIDViewModel.register function eventually calls the standard Gigya function createUser(withEmail: password:) to register the user in Gigya, so you do not need to call this Gigya function yourself.

Add the OwnID View

Inserting the OwnID view into your View layer results in the Skip Password option appearing in your app. When the user selects Skip Password, the SDK opens a sheet to interact with the user. The code that creates this view accepts the OwnID view model as its argument. It is suggested that you pass user's email binding for properly creating accounts.

It is reccomended to set height of button the same as text field and disable text field when OwnID is enabled.

how it looks like how it looks like

Complete example

//Put RegisterView inside your main view, preferably besides password field
var body: some View {
    OwnID.GigyaSDK.createRegisterView(viewModel: viewModel.ownIDViewModel, email: usersEmail)
}

It is recommended that you hide OwnID.FlowsSDK.RegisterView when the user starts typing in the password text field. Complete example

Implement the Login Screen

The process of implementing your Login screen is very similar to the one used to implement the Registration screen. When the user selects Skip Password on the Login screen and if the user has previously set up OwnID authentication, allows them to log in with OwnID.

Like the Registration screen, you add Skip Password to your application's Login screen by including an OwnID view. In this case, it is OwnID.LoginView. This OwnID view has its own view model, OwnID.LoginView.ViewModel.

Customize View Model

You need to create an instance of the view model, OwnID.LoginView.ViewModel, that the OwnID login view uses. Within your ViewModel layer, enter:

Complete example

final class MyLogInViewModel: ObservableObject {
    // MARK: OwnID
    let ownIDViewModel = OwnID.GigyaSDK.loginViewModel(instance: <Your Instance Of Gigya>)
}

After creating this OwnID view model, your View Model layer should listen to events from the OwnID Event Publisher, which allows your app to know what actions to take based on the user's interaction with the Skip Password option. Simply add the following to your existing ViewModel layer to subscribe to the OwnID Event Publisher and respond to events.

Complete example

final class MyLogInViewModel: ObservableObject {
    // MARK: OwnID
    let ownIDViewModel = OwnID.GigyaSDK.loginViewModel(instance: <Your Instance Of Gigya>)

 	  init() {
       subscribe(to: ownIDViewModel.eventPublisher)
   	}

     func subscribe(to eventsPublisher: OwnID.LoginPublisher) {
       eventsPublisher
           .receive(on: DispatchQueue.main)
           .sink { [unowned self] event in
               switch event {
               case .success(let event):
                   switch event {
                   // Event when user who previously set up
                   // OwnID logs in with Skip Password
                   case .loggedIn:
                     // User is logged in with OwnID
                     
                   case .loading:
                     // Display loading indicator according to your designs
                   }

               case .failure(let error):
                 // Handle OwnID.CoreSDK.Error here
               }
           }
           .store(in: &bag)
   }
}

Add OwnID View

Inserting the OwnID view into your View layer results in the Skip Password option appearing in your app. When the user selects Skip Password, the SDK opens a sheet to interact with the user. It is recommended that you place the OwnID view, OwnID.LoginView, immediately after the password text field. The code that creates this view accepts the OwnID view model as its argument. It is suggested that you pass user's email binding for properly creating accounts.

Complete example Complete example

//Put LoginView inside your main view, preferably below password field
var body: some View {
  //...
  // User's email binding `$viewModel.email` is used to display identity
  // name when logging in. Additionally, this email is used to get
  // information if user already has OwnID account
  OwnID.GigyaSDK.createLoginView(viewModel: viewModel.ownIDViewModel,
                                 usersEmail: $viewModel.email)
  //...
}

how it looks like how it looks like

It is recommended that you hide OwnID.FlowsSDK.LoginView when the user starts typing in the password text field. Complete example

Errors

All errors from the SDK have an OwnID.CoreSDK.Error type. You can use them, for example, to properly ask the user to perform an action.

Here are some of the possible errors: Complete example

switch error {
case .unsecuredHttpPassed:
    print("unsecuredHttpPassed")

case .notValidRedirectionURLOrNotMatchingFromConfiguration:
    print("notValidRedirectionURLOrNotMatchingFromConfiguration")

case .emailIsInvalid:
    print("emailIsInvalid")

case .flowCancelled:
    print("flowCancelled")

case .statusRequestResponseIsEmpty:
    print("statusRequestResponseIsEmpty")

case .statusRequestFail(underlying: let underlying):
    print("statusRequestFail: \(underlying)")

case .plugin(let pluginError):
    print("plugin: \(pluginError)")
}

Interruptions

The following is an example of handling interruptions:

Complete example

case .failure(let ownIDSDKError):
    switch ownIDSDKError {
    case .plugin(let gigyaPluginError):
        if let gigyaSDKError = gigyaPluginError as? OwnID.GigyaSDKError<Your Account Protocol Of Gigya> {
            switch gigyaSDKError {
            case .login(let loginError):
                switch loginError.interruption {
                case .pendingVerification:
                    print("pendingVerification")

                default:
                    break
                }
            default:
                break
            }
        }

    default:
        break
    }

Advanced Configuration

Button Apperance

It is possible to set button visual settings by passing OwnID.UISDK.VisualLookConfig.

let config = OwnID.UISDK.VisualLookConfig(buttonForegroundColor: .red,
                                          backgroundColor: .brown,
                                          borderColor: .brown,
                                          shadowColor: .cyan)
OwnID.GigyaSDK.createLoginView(viewModel: ownIDViewModel,
                               usersEmail: usersEmail,
                               visualConfig: config)

Alternative Syntax for Configure Function 🎛

If you followed the recommendation to add OwnIDConfiguration.plist to your project, calling configure() without any arguments is enough to initialize the SDK. If you did not follow this recommendation, you can still initialize the SDK with one of the following calls. Remember that these calls should be made within your app's @main App struct.

  • OwnID.GigyaSDK.configure(plistUrl: plist) explicitly provides the path to the OwnID configuration file, where plist is the path to the file.
  • OwnID.GigyaSDK.configure(appID: String, redirectionURL: URL) explicitly defines the configuration options rather than using a PLIST file. The server app id is unique to your OwnID application, and can be obtained in the OwnID Console. The redirection URL is your app's redirection URL, including its custom scheme.

OwnID Web App language

By default, the OwnID Web App is launched with a language TAGs list (well-formed IETF BCP 47 language tag) based on the device locales set by the user in system. You can override this behavior and set the Web App language list manually by passing languages in an array. Example:

OwnID.GigyaSDK.createRegisterView(viewModel: viewModel.ownIDViewModel,
                                  webLanguages: OwnID.CoreSDK.Languages.init(rawValue: ["he"]))

Directing Users to the OwnID iOS App

By default, the SDK directs the user to the OwnID Web App to register or login with OwnID. However, with a small configuration, users who have the native OwnID app installed on their mobile device can complete the registration/login process in the native app rather than the web app.

To direct the user to the OwnID native app, edit the LSApplicationQueriesSchemes key in your Info.plist file. Simply add ownidopener as a string in the LSApplicationQueriesSchemes array. Example: Complete example

<key>LSApplicationQueriesSchemes</key>
<array>
  <string>ownidopener</string>
</array>

Logging

You can enable console logging by calling OwnID.startDebugConsoleLogger().
