Telemetry Swift Client Reference

The Telemetry Swift Client is a Swift Package to include in your app

Include the Swift Client in your Xcode Project

See the Article Setting up your App on how to set up your app to use the Telemetry Swift Client.


Init the Telemetry Manager at app startup, so it knows your App ID (you can retrieve the App ID in the Telemetry Viewer app, under App Settings)

let configuration = TelemetryManagerConfiguration(appID: "<YOUR-APP-ID>")
TelemetryManager.initialize(with: configuration)

For example, if you're building a scene based app, in the init() function for your App:

import SwiftUI
import TelemetryClient

struct TelemetryTestApp: App {
    var body: some Scene {
        WindowGroup {

    init() {
        // Note: Do not add this code to `WindowGroup.onAppear`, which will be called 
        //       *after* your window has been initialized, and might lead to out initialization
        //       occurring too late.
        let configuration = TelemetryManagerConfiguration(appID: "<YOUR-APP-ID>")
        TelemetryManager.initialize(with: configuration)

Sending Signals

Once you've included the Telemetry Swift Client, send signals like so:


Telemetry Manager will create a user identifier for you user that is specific to app installation and device. If you have a better user identifier available, you can use that instead: (the identifier will be hashed before sending it)

let email = MyConfiguration.User.Email
TelemetryManager.send("userLoggedIn", for: email)

Payload Data

You can also send additional payload data with each signal:

TelemetryManager.send("databaseUpdated", with: ["numberOfDatabaseEntries": "3831"])

Telemetry Manager will automatically send a base payload with these keys:

  • platform
  • systemVersion
  • appVersion
  • buildNumber
  • isSimulator
  • isTestFlight
  • isAppStore
  • modelName
  • architecture
  • operatingSystem
  • targetEnvironment

Debug Mode

Telemetry Manager will not send any signals if you are in DEBUG Mode. You can override this by setting configuration.telemetryAllowDebugBuilds = true on your TelemetryManagerConfiguration instance.
