Overview

Datadog Real User Monitoring (RUM) enables you to visualize and analyze the real-time performance and user journeys of your application’s individual users.

Setup

Declare the SDK as a dependency.
Specify application details in the UI.
Initialize the library.
Initialize the RUM Monitor and enable URLSessionInstrumentation, to start sending data.

Declare the SDK as a dependency

Declare the library as a dependency depending on your package manager. Swift Package Manager (SPM) is recommended.

To integrate using Apple’s Swift Package Manager, add the following as a dependency to your Package.swift:

.package(url: "https://github.com/Datadog/dd-sdk-ios.git", .upToNextMajor(from: "2.0.0"))

In your project, link the following libraries:

DatadogCore
DatadogRUM

You can use CocoaPods to install dd-sdk-ios:

pod 'DatadogCore'
pod 'DatadogRUM'

You can use Carthage to install dd-sdk-ios:

github "DataDog/dd-sdk-ios"

In Xcode, link the following frameworks:

DatadogInternal.xcframework
DatadogCore.xcframework
DatadogRUM.xcframework

Specify application details in the UI

Navigate to Digital Experience > Add an Application.
Select iOS as the application type and enter an application name to generate a unique Datadog application ID and client token.
To instrument your web views, click the Instrument your webviews toggle. For more information, see Web View Tracking.
To disable automatic user data collection for either client IP or geolocation data, uncheck the boxes for those settings. For more information, see RUM iOS Data Collected.

To ensure the safety of your data, you must use a client token. If you used only Datadog API keys to configure the dd-sdk-ios library, they would be exposed client-side in the iOS application’s byte code.

For more information about setting up a client token, see the Client token documentation.

Initialize the library

In the initialization snippet, set an environment name, service name, and version number. In the examples below, app-name specifies the variant of the application that generates data.

For more information, see Using Tags.

The RUM iOS SDK automatically tracks user sessions depending on options provided at the SDK initialization. To add GDPR compliance for your EU users and other initialization parameters to the SDK configuration, see the Set tracking consent documentation.

Sample RUM sessions

To control the data your application sends to Datadog RUM, you can specify a sampling rate for RUM sessions while initializing the RUM iOS SDK as a percentage between 0 and 100.

For example, to only keep 50% of sessions use:

let configuration = RUM.Configuration(
    applicationID: "<rum application id>",
    sessionSampleRate: 50
)

DDRUMConfiguration *configuration = [[DDRUMConfiguration alloc] initWithApplicationID:@"<rum application id>"];
configuration.sessionSampleRate = 50;

To be compliant with the GDPR regulation, the RUM iOS SDK requires the tracking consent value at initialization.

The trackingConsent setting can be one of the following values:

.pending: The RUM iOS SDK starts collecting and batching the data but does not send it to Datadog. The RUM iOS SDK waits for the new tracking consent value to decide what to do with the batched data.
.granted: The RUM iOS SDK starts collecting the data and sends it to Datadog.
.notGranted: The RUM iOS SDK does not collect any data. No logs, traces, or RUM events are sent to Datadog.

To change the tracking consent value after the RUM iOS SDK is initialized, use the Datadog.set(trackingConsent:) API call. The RUM iOS SDK changes its behavior according to the new value.

For example, if the current tracking consent is .pending:

If you change the value to .granted, the RUM iOS SDK sends all current and future data to Datadog;
If you change the value to .notGranted, the RUM iOS SDK wipes all current data and does not collect future data.

Initialize the RUM Monitor and enable `URLSessionInstrumentation`

Configure and register the RUM Monitor. You only need to do it once, usually in your AppDelegate code:

import DatadogRUM

RUM.enable(
  with: RUM.Configuration(
    applicationID: "<rum application id>",
    uiKitViewsPredicate: DefaultUIKitRUMViewsPredicate(),
    uiKitActionsPredicate: DefaultUIKitRUMActionsPredicate(),
    urlSessionTracking: RUM.Configuration.URLSessionTracking()
  )
)

@import DatadogObjc;

DDRUMConfiguration *configuration = [[DDRUMConfiguration alloc] initWithApplicationID:@"<rum application id>"];
configuration.uiKitViewsPredicate = [DDDefaultUIKitRUMViewsPredicate new];
configuration.uiKitActionsPredicate = [DDDefaultUIKitRUMActionsPredicate new];
[configuration setURLSessionTracking:[DDRUMURLSessionTracking new]];

[DDRUM enableWith:configuration];

To monitor requests sent from the URLSession instance as resources, enable URLSessionInstrumentation for your delegate type and pass the delegate instance to the URLSession:

URLSessionInstrumentation.enable(
    with: .init(
        delegateClass: <YourSessionDelegate>.self
    )
)

let session = URLSession(
    configuration: .default,
    delegate: <YourSessionDelegate>(),
    delegateQueue: nil
)

DDURLSessionInstrumentationConfiguration *config = [[DDURLSessionInstrumentationConfiguration alloc] initWithDelegateClass:[<YourSessionDelegate> class]];
[DDURLSessionInstrumentation enableWithConfiguration:config];

NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]
                                                      delegate:[[<YourSessionDelegate> alloc] init]
                                                 delegateQueue:nil];

Instrument views

The Datadog iOS SDK for RUM allows you to instrument views of SwiftUI applications. The instrumentation also works with hybrid UIKit and SwiftUI applications.

To instrument a SwiftUI.View, add the following method to your view declaration:

import SwiftUI
import DatadogRUM

struct FooView: View {

    var body: some View {
        FooContent {
            ...
        }
        .trackRUMView(name: "Foo")
    }
}

The trackRUMView(name:) method starts and stops a RUM view when the SwiftUI view appears and disappears from the screen.

Instrument tap actions

The Datadog iOS SDK for RUM allows you to instrument tap actions of SwiftUI applications. The instrumentation also works with hybrid UIKit and SwiftUI applications.

To instrument a tap action on a SwiftUI.View, add the following method to your view declaration:

import SwiftUI
import DatadogRUM

struct BarView: View {

    var body: some View {
        Button("BarButton") { {
            ...
        }
        .trackRUMTapAction(name: "Bar")
    }
}

Track background events

Tracking background events may lead to additional sessions, which can impact billing. For questions, contact Datadog support.

You can track events such as crashes and network requests when your application is in the background (for example, no active view is available).

Add the following snippet during initialization in your Datadog configuration:

import DatadogRUM

RUM.enable(
  with: RUM.Configuration(
    ...
    trackBackgroundEvents: true
  )
)

Track iOS errors

iOS Crash Reporting and Error Tracking displays any issues in your application and the latest available errors. You can view error details and attributes including JSON in the RUM Explorer.

Sending data when device is offline

RUM ensures availability of data when your user device is offline. In cases of low-network areas, or when the device battery is too low, all the RUM events are first stored on the local device in batches. They are sent as soon as the network is available, and the battery is high enough to ensure the RUM iOS SDK does not impact the end user’s experience. If the network is not available while your application is in the foreground, or if an upload of data fails, the batch is kept until it can be sent successfully.

This means that even if users open your application while offline, no data is lost.

Note: The data on the disk is automatically discarded if it gets too old to ensure the RUM iOS SDK does not use too much disk space.
