PostHog integration for Swift iOS and macOS applications
— the description by PostHog

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill provides a systematic, multi-step process for developers to integrate PostHog analytics into Swift applications. It covers the entire lifecycle of the integration, from initial project setup and dependency management via Swift Package Manager to implementing event tracking, user identification, and error reporting. The workflow emphasizes best practices such as using environment variables for configuration, maintaining clean project structures, and ensuring consistent event tracking patterns across both iOS and macOS platforms.

What it does

  • Guides the setup of PostHog SDK dependencies using Swift Package Manager.
  • Defines a secure configuration pattern using environment variables for API keys and hosts.
  • Provides a structured approach to identifying users during authentication flows.
  • Outlines methods for tracking custom events and screen views to monitor user behavior.
  • Includes instructions for implementing error tracking to capture application issues.
  • Ensures compatibility with macOS App Sandbox requirements for network connectivity.

When to use it

  • When you need to add product analytics to a new or existing Swift iOS or macOS project.
  • When you want to implement consistent user identification and event tracking patterns.
  • When you need to capture application errors and critical user journey events.
  • When you require a standardized approach to managing PostHog configuration across different build environments.

Advantages

  • Promotes secure credential management by enforcing the use of environment variables.
  • Ensures a consistent implementation pattern through provided examples and guidelines.
  • Reduces integration errors by following a step-by-step, verified workflow.
  • Supports multi-platform development for iOS, iPadOS, and macOS.

Usage examples

“How do I start integrating PostHog into my new Swift iOS project?”
The agent will guide you through the initial setup, including adding the PostHog dependency via Swift Package Manager and configuring your environment variables in the Xcode scheme.
“How should I identify users in my Swift app after they log in?”
The agent will provide the specific code pattern to call PostHogSDK.shared.identify with the user's unique properties, ensuring events are correctly associated with the authenticated user.

PostHog integration for Swift (iOS/macOS)

This skill helps you add PostHog analytics to Swift (iOS/macOS) applications.

Workflow

Follow these steps in order to complete the integration:

  1. basic-integration-1.0-begin.md - PostHog Setup - Begin ← Start here

  2. basic-integration-1.1-edit.md - PostHog Setup - Edit

  3. basic-integration-1.2-revise.md - PostHog Setup - Revise

  4. basic-integration-1.3-conclude.md - PostHog Setup - Conclusion

Reference files

  • references/EXAMPLE.md - Swift (iOS/macOS) example project code

  • references/ios.md - Ios - docs

  • references/identify-users.md - Identify users - docs

  • references/basic-integration-1.0-begin.md - PostHog setup - begin

  • references/basic-integration-1.1-edit.md - PostHog setup - edit

  • references/basic-integration-1.2-revise.md - PostHog setup - revise

  • references/basic-integration-1.3-conclude.md - PostHog setup - conclusion

The example project shows the target implementation pattern. Consult the documentation for API details.

Key principles

  • Environment variables: Always use environment variables for PostHog keys. Never hardcode them.

  • Minimal changes: Add PostHog code alongside existing integrations. Don't replace or restructure existing code.

  • Match the example: Your implementation should follow the example project's patterns as closely as possible.

Framework guidelines

  • Read configuration from environment variables via a PostHogEnv enum with a value computed property that calls ProcessInfo.processInfo.environment[rawValue] and fatalErrors if missing — cases should be projectToken = "POSTHOG_PROJECT_TOKEN" and host = "POSTHOG_HOST", set in the Xcode scheme's Run environment variables

  • When adding SPM dependencies to project.pbxproj, create three distinct objects with unique UUIDs — a PBXBuildFile (with productRef), an XCSwiftPackageProductDependency (with package and productName), and an XCRemoteSwiftPackageReference (with repositoryURL and requirement). The build file goes in the Frameworks phase files, the product dependency goes in the target's packageProductDependencies, and the package reference goes in the project's packageReferences.

  • Check the latest release version of posthog-ios at https://github.com/PostHog/posthog-ios/releases before setting the minimumVersion in the SPM package reference — do not hardcode a stale version

  • If the project uses App Sandbox (macOS), add ENABLE_OUTGOING_NETWORK_CONNECTIONS = YES to the target's build settings so PostHog can reach its servers — do NOT disable the sandbox entirely

Identifying users

Identify users during login and signup events. Refer to the example code and documentation for the correct identify pattern for this framework. If both frontend and backend code exist, pass the client-side session and distinct ID using X-POSTHOG-DISTINCT-ID and X-POSTHOG-SESSION-ID headers to maintain correlation.

Error tracking

Add PostHog error tracking to relevant files, particularly around critical user flows and API boundaries.
