Requirements

• Latest stable Xcode from the App Store, 16.0 or later.
• Swift 5.9 or later.
• Minimum deployment target iOS 13.

Integration

The DevRev SDK can be integrated through Swift Package Manager (SPM) or CocooaPods.

Note

We recommend integrating the DevRev SDK using Swift Package Manager.

Swift Package Manager (Recommended)

You can integrate the DevRev SDK in your project as a Swift Package Manager (SPM) package.

Open your project in Xcode, go to the Add Package screen, add the following URL under Enter Package URL:

• HTTPS:

   https://github.com/devrev/devrev-sdk-ios
  

• or using SSH:

   git@github.com:devrev/devrev-sdk-ios.git
  

Make sure you link the framework under the Build Phases screen of your app target. Find the Link Binary With Libraries phase and make sure that DevRevSDK is linked there.

Now you should be able to import and use the DevRev SDK.

CocoaPods

The DevRev SDK can also be integrated using CocoaPods. Add the following line to your Podfile:

pod 'DevRevSDK', '~> 1.0.0'

Then run pod install in your project directory.

Setting up the DevRev SDK

Step 1: Credentials

1. Open the DevRev web app at https://app.devrev.ai.
2. Go to the Settings page.
3. Then open the PLuG Settings page, and copy the value under Your Unique App ID.

Step 2: Configuration

Important

The SDK must be configured before you can use any of its features.

Once you have the credentials, you can configure the DevRev SDK in your app. The SDK will be ready to use once you have called the configuration method:

DevRev.configure(appID:)

Example

DevRev.configure(appID: "abcdefg12345")

UIKit apps

Configure the SDK in the AppDelegate.application(_:didFinishLaunchingWithOptions:) method.

SwiftUI apps

Depending on the architecture of your app, you will need to configure the SDK at your entry point or initial view of the app.

Features

Identification

Certain features of the DevRev SDK require a user identification. There are two methods to identify your users:

• Anonymous users: Creates an anonymous user with an optional user identifier, no other data is stored or associated with the user.
• Unverified users: Identifies the user with a unique identifier, but does not verify the user's identity with the DevRev backend.

The identification functions should be placed at the appropriate place in your app after you login your user. If you have the user information at app launch, call the function after the DevRev.configure(appID:) method.

Important

If you haven't previously identified the user, the DevRev SDK will automatically create an anonymous user for you right after the SDK has been configured.

Anonymous identification

The anonymous identification method is used to create an anonymous user with an optional user identifier.

DevRev.identifyAnonymousUser(userID:)

Unverified identification

The unverified identification method is used to identify the user with a unique identifier, but does not verify the user's identity with the DevRev backend.

DevRev.identifyUnverifiedUser(_:)

The function accepts the DevRev.Identity structure, with the user identifier (userID) as the only required property, all other properties are optional.

Updating the user

You can update the user's information using the following method:

DevRev.updateUser(_:)

The function accepts the DevRev.Identity structure.

Examples

Note

The identification functions are asynchronous, make sure that you wrap them in a Task when calling them from synchronous contexts.

// Identify an anonymous user without a user identifier.
await DevRev.identifyAnonymousUser()

// Identify an unverified user with its email address an user identifier.
await DevRev.identifyUnverifiedUser(Identity(userID: "foo@example.org"))

// Update the user's information.
await DevRev.updateUser(Identity(organizationID: "foo-bar-1337"))

PLuG support chat

UIKit

The support chat feature can be shown as a modal screen from a specific view controller or the top-most one, or can be pushed onto a navigation stack.

The following overloaded method will show the support chat screen from a specific view controller or pushed to a navigation stack:

await DevRev.showSupport(from:isAnimated:)

1. When a UIViewController is passed as the from parameter, then the screen will be shown modally.
2. When a UINavigationController is passed as the from parameter, then the screen will be pushed onto the stack.

If you want to show the support chat screen from the top-most view controller, you can use the following method:

await DevRev.showSupport(isAnimated:)

Examples

/// Push the support chat screen to a navigation stack.
await DevRev.showSupport(from: mainNavigationController)

/// Show the support chat screen modally from a specific view controller.
await DevRev.showSupport(from: settingsViewController)

/// Show the support chat screen from the top-most view controller, without an animation.
await DevRev.showSupport(isAnimated: false)

SwiftUI

In order to show the support chat screen in a SwiftUI app, you can use the following view:

DevRev.supportView

New conversation closure

When a new conversation has been created, you can receive a callback using the closure below:

DevRev.conversationCreatedCompletion

That way your app will be able to access the ID of the newly created conversation.

Example

DevRev.conversationCreatedCompletion = { conversationID in
	print("A new conversation has been created: \(conversationID).")
}

Analytics

The DevRev SDK supports sending custom analytic events using a name and a string dictionary.

You can track them using the following function:

DevRev.trackEvent(name:properties:)

Example

await DevRev.trackEvent(name: "open-message-screen", properties: ["id": "foo-bar-1337"])

Observability

The DevRev SDK provides observability features to help you understand how your users are interacting with your app.

Opting in/out

The observability features are opted-in by default, meaning that they are enabled from start. You can opt-out of the observability features by calling the following method:

DevRev.stopAllMonitoring()

To opt back in, you can call the following method:

DevRev.resumeAllMonitoring()

Session recording

You can enable session recording to record user interactions with your app.

Caution

The session recording feature is opt-out and is enabled by default.

The session recording feature has a number of methods to help you control the recording:

• DevRev.startRecording(): Starts the session recording.
• DevRev.stopRecording(): Stops the session recording and uploads it to the portal.
• DevRev.pauseRecording(): Pauses the ongoing session recording.
• DevRev.resumeRecording(): Resumes a paused session recording.

Session properties

You can add custom properties to the session recording to help you understand the context of the session. The properties are defined as a dictionary of string values.

DevRev.addSessionProperties(_:)

You also have the ability to clear the session properties in scenarios like user logout or when the session ends.

DevRev.clearSessionProperties()

Masking sensitive data

In order to protect sensitive data the DevRev SDK provides an auto-masking feature, which masks the data before it is being sent to the server. Input views such as text fields, text views, and web views are automatically masked.

While the auto-masking mechanism might be sufficient for most cases, you can also manually mark other views as sensitive using the following method:

DevRev.markSensitiveViews(_:)

If any previously masked views need to be unmasked, you can use the following method:

DevRev.unmarkSensitiveViews(_:)

Timers

As part of the observability features, the DevRev SDK provides a timer mechanism to help you measure the time spent on a specific task. Events such as response time, loading time, or any other time-based event can be measured using the timer.

The mechanism works using balanced start and stop methods that both accept a timer name and an optional dictionary of properties.

Start a timer using the method:

DevRev.startTimer(_:properties:)

And balance it with the stop method:

DevRev.stopTimer(_:properties:)

Example

DevRev.startTimer("response-time", properties: ["id": "foo-bar-1337"])

// Perform the task that you want to measure.

DevRev.stopTimer("response-time", properties: ["id": "foo-bar-1337"])

Screen tracking

The DevRev SDK provides automatic screen tracking to help you understand how users are navigating through your app. While view controllers are automatically tracked, you can also manually track screens using the following method:

DevRev.trackScreenName(_:)

Example

DevRev.trackScreenName("profile-screen")

Push notifications

You can configure your app to receive push notifications from the DevRev SDK. The SDK is able to handle push notifications and perform actions based on the content of the notification.

The DevRev backend sends push notifications to your app to notify users about new messages in the PLuG support chat. In the future, the push notification support will be expanded with additional features.

Configuration

In order to receive push notifications, you need to configure your DevRev organization by following the Push Notifications integration guide.

You need to make sure that your iOS app is configured to receive push notifications. You can follow the Apple documentation to set up your app to receive push notifications.

Registering for push notifications

Important

Push notifications require that the SDK has been configured and the user has been identified (unverified and anonymous users). The user identification is required to send the push notification to the correct user.

The DevRev SDK provides a method to register your device for receiving push notifications. You can call the following method to register for push notifications:

DevRev.registerDeviceToken(_:deviceID:)

The method requires a device identifier, which might be an identifier unique to your system or the Apple provided vendor identifier (IDFV). The registration is usually called from the AppDelegate.application(_:didRegisterForRemoteNotificationsWithDeviceToken:) method.

Example

func application(
	_ application: UIApplication,
	didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data
) {
	guard
		let deviceID = UIDevice.current.identifierForVendor?.uuidString
	else {
		return
	}

	Task {
		await DevRev.registerDeviceToken(
			deviceToken,
			deviceID: deviceID
		)
	}
}

Unregistering from push notifications

In cases when your app no longer wants to receive push notifications, you can unregister the device from receiving them. The method to unregister the device is:

DevRev.unregisterDevice(_:)

The method requires the device identifier, which is the same as the one used for registering the device. The best place to place the method is after you call UIApplication.unregisterForRemoteNotifications() in your app.

Example

UIApplication.shared.unregisterForRemoteNotifications()

Task {
	guard
		let deviceID = UIDevice.current.identifierForVendor?.uuidString
	else {
		return
	}

	await DevRev.unregisterDevice(deviceID)
}

Handling push notifications

In order to properly handle push notifications, you need to implement the following method, usually in the UNUserNotificationCenterDelegate.userNotificationCenter(_:didReceive:) or UIApplicationDelegate.application(_:didReceiveRemoteNotification:fetchCompletionHandler:):

DevRev.processPushNotification(_:)

Example

func userNotificationCenter(
	_ center: UNUserNotificationCenter,
	didReceive response: UNNotificationResponse
) async {
	await DevRev.processPushNotification(response.notification.request.content.userInfo)
}

Sample app

A sample app with use cases for both UIKit and SwiftUI has been provided as part of this repository.

Before you start using the sample app you will need to configure it to be used with your Apple Developer team and your DevRev credentials. For your convenience the code has been marked with compiler error directives (#error) at the places that need attention.

1. Add your credentials to ContentView.swift (SwiftUI) or AppDelegate.swift (UIKit).
   • After you have added the credentials, delete or comment out the compiler error lines in the respective files.
2. Configure the code signing for the sample target:
   • Open the project settings (1),
   • Select the appropriate target (2),
   • Go to the Signing & Capabilities section (3), and
   • Select your development team under Team (4).
   

Troubleshooting

Cannot import the SDK into my app

Check the Setup again and make sure that the DevRevSDK framework is properly linked.

How does the DevRev SDK handle errors?

The DevRev SDK outputs all errors in the console using Apple's Unified Logging System under the subsystem ai.devrev.sdk.

Why won't the support chat show?

Make sure you have called one of the identification methods properly (DevRev.identifyUnverifiedUser(...) or DevRev.identifyAnonymousUser(...)).

Why am I not receiving push notifications?

Make sure that you have configured your app to receive push notifications and that you have registered your device with the DevRev SDK.
