Unified SDK for Swift

Unifed SDK for Swift

The Unified SDK for Swift is in beta and undergoing testing.

This is the official documentation for the Amplitude Unified SDK for Swift.

The Unified SDK is a wrapper around Amplitude's existing SDKs, providing a simplified interface to use multiple Amplitude products together. It currently includes:

Install the SDK

Add the dependency to your Podfile:

pod 'AmplitudeUnified', '~> 0.0.0'

pod 'AmplitudeUnified', '~> 0.0.0'

Run pod install in the project directory.

Navigate to File > Swift Package Manager > Add Package Dependency. This opens a dialog that allows you to add a package dependency.

Enter the URL https://github.com/amplitude/AmplitudeUnified-Swift in the search bar.

Xcode automatically resolves to the latest version. Or you can select a specific version.

Click the "Next" button to confirm the addition of the package as a dependency.

Build your project to make sure the package is properly integrated.

Initialize the SDK

You must initialize the SDK before you can instrument. The API key for your Amplitude project is required.

// Basic initialization with default configurations
let amplitude = Amplitude(
    apiKey: "YOUR_API_KEY"
)
 
// Advanced initialization with custom configurations
let amplitude = Amplitude(
    apiKey: "YOUR_API_KEY",
    serverZone: .US,
    instanceName: "default_instance",
    analyticsConfig: AnalyticsConfig(),
    experimentConfig: ExperimentPlugin.Config(),
    sessionReplayConfig: SessionReplayPlugin.Config(),
    logger: ConsoleLogger()
)

// Basic initialization with default configurations
let amplitude = Amplitude(
    apiKey: "YOUR_API_KEY"
)
// Advanced initialization with custom configurations
let amplitude = Amplitude(
apiKey: "YOUR_API_KEY",
serverZone: .US,
instanceName: "default_instance",
analyticsConfig: AnalyticsConfig(),
experimentConfig: ExperimentPlugin.Config(),

Configure the SDK

Analytics Configuration

The Unified SDK provides a simplified configuration interface for the Analytics SDK. For a complete list of configuration options, see the Analytics SDK documentation.

let analyticsConfig = AnalyticsConfig(
    flushQueueSize: 30,
    flushIntervalMillis: 30000,
    trackingOptions: TrackingOptions().disableTrackCity().disableTrackIpAddress(),
    minTimeBetweenSessionsMillis: 300000,
    autocapture: [.sessions, .appLifecycles, .screenViews]
)
 
let amplitude = Amplitude(
    apiKey: "YOUR_API_KEY",
    analyticsConfig: analyticsConfig
)

let analyticsConfig = AnalyticsConfig(
    flushQueueSize: 30,
    flushIntervalMillis: 30000,
    trackingOptions: TrackingOptions().disableTrackCity().disableTrackIpAddress(),
    minTimeBetweenSessionsMillis: 300000,
    autocapture: [.sessions, .appLifecycles, .screenViews]
)
let amplitude = Amplitude(
apiKey: "YOUR_API_KEY",
analyticsConfig: analyticsConfig
)

AMPAnalyticsConfig *analyticsConfig = [[AMPAnalyticsConfig alloc] init];
analyticsConfig.flushQueueSize = 30;
analyticsConfig.flushIntervalMillis = 30000;
[analyticsConfig.trackingOptions disableTrackCity];
[analyticsConfig.trackingOptions disableTrackIpAddress];
analyticsConfig.minTimeBetweenSessionsMillis = 300000;

    AMPAutocaptureOptions.sessions,
    AMPAutocaptureOptions.appLifecycles,
    AMPAutocaptureOptions.screenViews
]];
 
Amplitude *amplitude = [[Amplitude alloc] initWithApiKey:@"YOUR_API_KEY"
                                         analyticsConfig:analyticsConfig];

AMPAnalyticsConfig *analyticsConfig = [[AMPAnalyticsConfig alloc] init];
analyticsConfig.flushQueueSize = 30;
analyticsConfig.flushIntervalMillis = 30000;
[analyticsConfig.trackingOptions disableTrackCity];
[analyticsConfig.trackingOptions disableTrackIpAddress];
analyticsConfig.minTimeBetweenSessionsMillis = 300000;
analyticsConfig.autocapture = [[AMPAutocaptureOptions alloc] initWithOptionsToUnion:@[
    AMPAutocaptureOptions.sessions,
    AMPAutocaptureOptions.appLifecycles,
    AMPAutocaptureOptions.screenViews
]];
Amplitude *amplitude = [[Amplitude alloc] initWithApiKey:@"YOUR_API_KEY"
analyticsConfig:analyticsConfig];

Experiment Configuration

The Unified SDK automatically configures the Experiment SDK with sensible defaults. For more advanced configuration options, see the Experiment SDK documentation.

let experimentConfig = ExperimentPlugin.Config(
    serverUrl: "https://api.lab.amplitude.com",
    debug: true,
    fetchTimeoutMillis: 10000
)
 
let amplitude = Amplitude(
    apiKey: "YOUR_API_KEY",
    experimentConfig: experimentConfig
)

let experimentConfig = ExperimentPlugin.Config(
    serverUrl: "https://api.lab.amplitude.com",
    debug: true,
    fetchTimeoutMillis: 10000
)
let amplitude = Amplitude(
apiKey: "YOUR_API_KEY",
experimentConfig: experimentConfig
)

AMPExperimentPluginConfig *experimentConfig = [[AMPExperimentPluginConfig alloc] init];
experimentConfig.serverUrl = @"https://api.lab.amplitude.com";
experimentConfig.debug = YES;
experimentConfig.fetchTimeoutMillis = 10000;
 
Amplitude *amplitude = [[Amplitude alloc] initWithApiKey:@"YOUR_API_KEY"
                                        experimentConfig:experimentConfig];

AMPExperimentPluginConfig *experimentConfig = [[AMPExperimentPluginConfig alloc] init];
experimentConfig.serverUrl = @"https://api.lab.amplitude.com";
experimentConfig.debug = YES;
experimentConfig.fetchTimeoutMillis = 10000;
Amplitude *amplitude = [[Amplitude alloc] initWithApiKey:@"YOUR_API_KEY"
experimentConfig:experimentConfig];

Session Replay Configuration

The Unified SDK automatically configures the Session Replay SDK with sensible defaults. For more advanced configuration options, see the Session Replay SDK documentation.

Note

Session Replay is only available on iOS platforms, not on macOS, tvOS, watchOS, or visionOS.

#if canImport(AmplitudeSessionReplay)
let sessionReplayConfig = SessionReplayPlugin.Config(
    sessionSampleRate: 100,
    scrollSampleRate: 50
)
 
let amplitude = Amplitude(
    apiKey: "YOUR_API_KEY",
    sessionReplayConfig: sessionReplayConfig
)
#endif

#if canImport(AmplitudeSessionReplay)
let sessionReplayConfig = SessionReplayPlugin.Config(
    sessionSampleRate: 100,
    scrollSampleRate: 50
)
let amplitude = Amplitude(
apiKey: "YOUR_API_KEY",
sessionReplayConfig: sessionReplayConfig
)
#endif

#if __has_include(<AmplitudeSessionReplay/AmplitudeSessionReplay.h>)
AMPSessionReplayPluginConfig *sessionReplayConfig = [[AMPSessionReplayPluginConfig alloc] init];
sessionReplayConfig.sessionSampleRate = 100;
sessionReplayConfig.scrollSampleRate = 50;
 
Amplitude *amplitude = [[Amplitude alloc] initWithApiKey:@"YOUR_API_KEY"
                                    sessionReplayConfig:sessionReplayConfig];
#endif

#if __has_include(<AmplitudeSessionReplay/AmplitudeSessionReplay.h>)
AMPSessionReplayPluginConfig *sessionReplayConfig = [[AMPSessionReplayPluginConfig alloc] init];
sessionReplayConfig.sessionSampleRate = 100;
sessionReplayConfig.scrollSampleRate = 50;
Amplitude *amplitude = [[Amplitude alloc] initWithApiKey:@"YOUR_API_KEY"
sessionReplayConfig:sessionReplayConfig];
#endif

Using the SDK

The Unified SDK provides access to all the functionality of the individual SDKs through a single interface.

Analytics

The Unified SDK exposes all the Analytics SDK functionality directly. For a complete list of methods, see the Analytics SDK documentation.

// Track an event
amplitude.track(eventType: "Button Clicked", eventProperties: ["button_id": "sign_up"])
 
// Set user properties
let identify = Identify()
identify.set(property: "plan", value: "premium")
amplitude.identify(identify: identify)
 
// Set user ID
amplitude.setUserId(userId: "user@example.com")

// Track an event
amplitude.track(eventType: "Button Clicked", eventProperties: ["button_id": "sign_up"])
// Set user properties
let identify = Identify()
identify.set(property: "plan", value: "premium")
amplitude.identify(identify: identify)
// Set user ID
amplitude.setUserId(userId: "user@example.com")

// Track an event
[amplitude track:@"Button Clicked" eventProperties:@{@"button_id": @"sign_up"}];
 
// Set user properties
AMPIdentify *identify = [AMPIdentify new];
[identify set:@"plan" value:@"premium"];
[amplitude identify:identify];
 
// Set user ID
[amplitude setUserId:@"user@example.com"];

// Track an event
[amplitude track:@"Button Clicked" eventProperties:@{@"button_id": @"sign_up"}];
// Set user properties
AMPIdentify *identify = [AMPIdentify new];
[identify set:@"plan" value:@"premium"];
[amplitude identify:identify];
// Set user ID
[amplitude setUserId:@"user@example.com"];

Experiment

The Experiment SDK is automatically initialized and configured when you create an Amplitude instance with the Unified SDK. You can access the Experiment client through the experiment property.

// Fetch variants for the current user
amplitude.experiment.fetch().onFetchCompleted { error in
    if let error = error {
        print("Error fetching variants: \(error)")
        return
    }
 
    // Get a variant for a flag
    let variant = amplitude.experiment.variant("my-flag")
    print("Variant: \(variant.value)")
 
    // Evaluate a flag locally
    let localVariant = amplitude.experiment.variant("local-flag", fallback: "default")
    print("Local variant: \(localVariant.value)")
 
    // Exposure tracking is automatic when you call variant()
    // But you can also track exposures manually
    amplitude.experiment.exposure("my-flag")
}

// Fetch variants for the current user
amplitude.experiment.fetch().onFetchCompleted { error in
    if let error = error {
        print("Error fetching variants: \(error)")
        return
    }
    
        // Get a variant for a flag
let variant = amplitude.experiment.variant(&quot;my-flag&quot;)
print(&quot;Variant: \(variant.value)&quot;)
 
// Evaluate a flag locally
let localVariant = amplitude.experiment.variant(&quot;local-flag&quot;, fallback: &quot;default&quot;)
print(&quot;Local variant: \(localVariant.value)&quot;)
 
// Exposure tracking is automatic when you call variant()
// But you can also track exposures manually
amplitude.experiment.exposure(&quot;my-flag&quot;)

// Get a variant for a flag
let variant = amplitude.experiment.variant(&quot;my-flag&quot;)
print(&quot;Variant: \(variant.value)&quot;)
// Evaluate a flag locally
let localVariant = amplitude.experiment.variant(&quot;local-flag&quot;, fallback: &quot;default&quot;)
print(&quot;Local variant: (localVariant.value)&quot;)
// Exposure tracking is automatic when you call variant()
// But you can also track exposures manually
amplitude.experiment.exposure(&quot;my-flag&quot;)

}

// Fetch variants for the current user
[[amplitude.experiment fetch] onFetchCompleted:^(NSError * _Nullable error) {
    if (error != nil) {
        NSLog(@"Error fetching variants: %@", error);
        return;
    }
 
    // Get a variant for a flag
    ExperimentVariant *variant = [amplitude.experiment variant:@"my-flag"];
    NSLog(@"Variant: %@", variant.value);
 
    // Evaluate a flag locally
    ExperimentVariant *localVariant = [amplitude.experiment variant:@"local-flag" fallback:@"default"];
    NSLog(@"Local variant: %@", localVariant.value);
 
    // Exposure tracking is automatic when you call variant()
    // But you can also track exposures manually
    [amplitude.experiment exposure:@"my-flag"];
}];

// Fetch variants for the current user
[[amplitude.experiment fetch] onFetchCompleted:^(NSError * _Nullable error) {
    if (error != nil) {
        NSLog(@"Error fetching variants: %@", error);
        return;
    }
    
        // Get a variant for a flag
ExperimentVariant *variant = [amplitude.experiment variant:@&quot;my-flag&quot;];
NSLog(@&quot;Variant: %@&quot;, variant.value);
 
// Evaluate a flag locally
ExperimentVariant *localVariant = [amplitude.experiment variant:@&quot;local-flag&quot; fallback:@&quot;default&quot;];
NSLog(@&quot;Local variant: %@&quot;, localVariant.value);
 
// Exposure tracking is automatic when you call variant()
// But you can also track exposures manually
[amplitude.experiment exposure:@&quot;my-flag&quot;];

// Get a variant for a flag
ExperimentVariant *variant = [amplitude.experiment variant:@&quot;my-flag&quot;];
NSLog(@&quot;Variant: %@&quot;, variant.value);

NSLog(@&quot;Local variant: %@&quot;, localVariant.value);
// Exposure tracking is automatic when you call variant()
// But you can also track exposures manually
[amplitude.experiment exposure:@&quot;my-flag&quot;];

}];

Session Replay

The Session Replay SDK is automatically initialized and configured when you create an Amplitude instance with the Unified SDK on iOS platforms. Session Replay isn't available on macOS, tvOS, watchOS, or visionOS.

#if canImport(AmplitudeSessionReplay)
// Session Replay is automatically initialized and configured
// You can access the Session Replay client through the sessionReplay property
 
// Start recording a session
amplitude.sessionReplay?.startRecording()
 
// Stop recording
amplitude.sessionReplay?.stopRecording()
 
// Pause recording
amplitude.sessionReplay?.pauseRecording()
 
// Resume recording
amplitude.sessionReplay?.resumeRecording()
#endif

#if canImport(AmplitudeSessionReplay)
// Session Replay is automatically initialized and configured
// You can access the Session Replay client through the sessionReplay property
// Start recording a session
amplitude.sessionReplay?.startRecording()
// Stop recording
amplitude.sessionReplay?.stopRecording()
// Pause recording
amplitude.sessionReplay?.pauseRecording()
// Resume recording
amplitude.sessionReplay?.resumeRecording()
#endif

#if __has_include(<AmplitudeSessionReplay/AmplitudeSessionReplay.h>)
// Session Replay is automatically initialized and configured
// You can access the Session Replay client through the sessionReplay property
 
// Start recording a session
[amplitude.sessionReplay startRecording];
 
// Stop recording
[amplitude.sessionReplay stopRecording];
 
// Pause recording
[amplitude.sessionReplay pauseRecording];
 
// Resume recording
[amplitude.sessionReplay resumeRecording];
#endif

#if __has_include(<AmplitudeSessionReplay/AmplitudeSessionReplay.h>)
// Session Replay is automatically initialized and configured
// You can access the Session Replay client through the sessionReplay property

// Pause recording
[amplitude.sessionReplay pauseRecording];
// Resume recording
[amplitude.sessionReplay resumeRecording];
#endif

Advanced topics

Follow instructions in this section to enable identity management and other features.

Identity management

The Unified SDK provides a unified identity management system that synchronizes user identity across all Amplitude products. When you set a user ID or device ID using the Amplitude methods, the changes are automatically propagated to Experiment and Session Replay.

// Set user ID - automatically propagated to all products
amplitude.setUserId(userId: "user@example.com")
 
// Set device ID - automatically propagated to all products
amplitude.setDeviceId(deviceId: "custom-device-id")
 
// Reset user - clears user ID and generates a new device ID
amplitude.reset()
 
// Access the current identity
let userId = amplitude.identity.userId
let deviceId = amplitude.identity.deviceId

// Set user ID - automatically propagated to all products
amplitude.setUserId(userId: "user@example.com")
// Set device ID - automatically propagated to all products
amplitude.setDeviceId(deviceId: "custom-device-id")
// Reset user - clears user ID and generates a new device ID
amplitude.reset()
// Access the current identity
let userId = amplitude.identity.userId
let deviceId = amplitude.identity.deviceId

// Set user ID - automatically propagated to all products
[amplitude setUserId:@"user@example.com"];
 
// Set device ID - automatically propagated to all products
[amplitude setDeviceId:@"custom-device-id"];
 
// Reset user - clears user ID and generates a new device ID
[amplitude reset];
 
// Access the current identity
NSString *userId = amplitude.identity.userId;
NSString *deviceId = amplitude.identity.deviceId;

// Set user ID - automatically propagated to all products
[amplitude setUserId:@"user@example.com"];
// Set device ID - automatically propagated to all products
[amplitude setDeviceId:@"custom-device-id"];
// Reset user - clears user ID and generates a new device ID
[amplitude reset];
// Access the current identity
NSString *userId = amplitude.identity.userId;
NSString *deviceId = amplitude.identity.deviceId;

User properties

The Unified SDK maintains a cache of user properties that are set with identify operations. This allows you to access the current user properties state at any time.

// Set user properties
let identify = Identify()
identify.set(property: "plan", value: "premium")
identify.set(property: "age", value: 25)
amplitude.identify(identify: identify)
 
// Access the current user properties
let userProperties = amplitude.identity.userProperties
print("User plan: \(userProperties["plan"] ?? "none")")
print("User age: \(userProperties["age"] ?? 0)")
 
// Clear all user properties
let clearIdentify = Identify()
clearIdentify.clearAll()
amplitude.identify(identify: clearIdentify)

// Set user properties
let identify = Identify()
identify.set(property: "plan", value: "premium")
identify.set(property: "age", value: 25)
amplitude.identify(identify: identify)
// Access the current user properties
let userProperties = amplitude.identity.userProperties
print("User plan: (userProperties["plan"] ?? "none")")
print("User age: (userProperties["age"] ?? 0)")
// Clear all user properties
let clearIdentify = Identify()
clearIdentify.clearAll()
amplitude.identify(identify: clearIdentify)

// Set user properties
AMPIdentify *identify = [AMPIdentify new];
[identify set:@"plan" value:@"premium"];
[identify set:@"age" value:@25];
[amplitude identify:identify];
 
// Access the current user properties
NSDictionary *userProperties = amplitude.identity.userProperties;
NSLog(@"User plan: %@", userProperties[@"plan"] ?: @"none");
NSLog(@"User age: %@", userProperties[@"age"] ?: @0);
 
// Clear all user properties
AMPIdentify *clearIdentify = [AMPIdentify new];
[clearIdentify clearAll];
[amplitude identify:clearIdentify];

// Set user properties
AMPIdentify *identify = [AMPIdentify new];
[identify set:@"plan" value:@"premium"];
[identify set:@"age" value:@25];
[amplitude identify:identify];
// Access the current user properties
NSDictionary *userProperties = amplitude.identity.userProperties;
NSLog(@"User plan: %@", userProperties[@"plan"] ?: @"none");
NSLog(@"User age: %@", userProperties[@"age"] ?: @0);
// Clear all user properties
AMPIdentify *clearIdentify = [AMPIdentify new];
[clearIdentify clearAll];
[amplitude identify:clearIdentify];

Debugging

To enable debug logging, set the log level to DEBUG in the Analytics configuration:

let analyticsConfig = AnalyticsConfig(
    // Other configuration options...
)
 
let amplitude = Amplitude(
    apiKey: "YOUR_API_KEY",
    analyticsConfig: analyticsConfig,
    logger: ConsoleLogger(logLevel: LogLevelEnum.DEBUG.rawValue)
)

let analyticsConfig = AnalyticsConfig(
    // Other configuration options...
)
let amplitude = Amplitude(
apiKey: "YOUR_API_KEY",
analyticsConfig: analyticsConfig,
logger: ConsoleLogger(logLevel: LogLevelEnum.DEBUG.rawValue)
)

AMPAnalyticsConfig *analyticsConfig = [[AMPAnalyticsConfig alloc] init];
// Other configuration options...
 
AMPConsoleLogger *logger = [[AMPConsoleLogger alloc] initWithLogLevel:AMPLogLevelDEBUG];
Amplitude *amplitude = [[Amplitude alloc] initWithApiKey:@"YOUR_API_KEY"
                                         analyticsConfig:analyticsConfig
                                                  logger:logger];

AMPAnalyticsConfig *analyticsConfig = [[AMPAnalyticsConfig alloc] init];
// Other configuration options...
AMPConsoleLogger *logger = [[AMPConsoleLogger alloc] initWithLogLevel:AMPLogLevelDEBUG];
Amplitude *amplitude = [[Amplitude alloc] initWithApiKey:@"YOUR_API_KEY"
analyticsConfig:analyticsConfig
logger:logger];

Common Issues

If your implementation of the Unified SDK doesn't work as you expect, make sure you account for the following common issues.

Session Replay not working on non-iOS platforms

Session Replay is only available on iOS platforms. It isn't available on macOS, tvOS, watchOS, or visionOS. The Unified SDK automatically detects the platform and only initialize Session Replay on iOS.

Events not showing up in Amplitude

If events don't appear in Amplitude:

Check that you're using the correct API key
Verify that the device has an internet connection
Make sure you wait long enough to ensure events flush (the default time is 30 seconds)
Check the logs for any error messages

Experiment flags aren't fetched

If Experiment flags aren't fetched:

Ensure you've called amplitude.experiment.fetch()
Check that the user ID or device ID is set correctly
Verify that you configure the flags correctly in the Amplitude Experiment dashboard
Check the logs for any error messages from the Experiment SDK

Migration guide

If you use the individual Amplitude SDKs separately, follow these steps to migrate to the Unified SDK:

Add the Unified SDK dependency to your project
Remove the individual SDK dependencies (AmplitudeSwift, Experiment, AmplitudeSessionReplay)
Replace your initialization code with the Unified SDK initialization
Update your API calls to use the Unified SDK interface
