Confidence score: 4/5 👍
File changes
App sanity check
|
| Criteria | Result | Description |
|---|---|---|
| App builds and runs | Yes | All SPM dependencies correctly declared, imports valid, syntax correct |
| Preserves existing env vars & configs | Yes | Existing functionality preserved; only additions made |
| No syntax or type errors | Yes | All Swift syntax is valid; PostHogSDK API usage matches documented patterns |
| Correct imports/exports | Yes | import PostHog used correctly in all feature modules |
| Minimal, focused changes | No | CI workflow changes (+120/-58 lines) are unrelated to PostHog integration |
| Pre-existing issues | None | No pre-existing issues noted |
Issues
- CI workflow changes are unrelated: The
.github/workflows/wizard-ci.ymlchanges (timeout, macOS gh install, step refactoring) are infrastructure changes unrelated to the PostHog integration. [LOW]
Other completed criteria
- Environment variables documented in Xcode scheme
- Build configuration is valid — SPM packages correctly added to all necessary Package.swift files and project.pbxproj
- All imports resolve to correct packages
PostHog implementation ⚠️
| Criteria | Result | Description |
|---|---|---|
| PostHog SDKs installed | Yes | posthog-ios v3.48.0 added via SPM in project.pbxproj and four feature Package.swift files |
| PostHog client initialized | Yes | PostHogConfig(apiKey:host:) + PostHogSDK.shared.setup(config) in SwiftUI App init() via PostHogAnalytics.setup() — follows docs exactly |
| capture() | Yes | 12 meaningful capture calls across 4 ViewModels |
| identify() | Yes | PostHogSDK.shared.identify(username, userProperties:) on login, PostHogSDK.shared.reset() on logout — correct pattern |
| Error tracking | No | No PostHog exception/crash tracking configured (e.g., captureException). Only manual error event captures for business logic failures. |
| Reverse proxy | N/A | iOS native app — reverse proxy not applicable |
Issues
- No error/exception tracking: The PR captures business-logic error events (login_failed, purchase_failed) but does not set up PostHog's error/exception tracking feature for crash reporting. [MEDIUM]
- API key placeholder committed in scheme: The Xcode scheme file contains
value = "phx_API_KEY_IS_HARDCODED"which is committed to source control. While the runtime reads from environment variables correctly viaPostHogEnv, the scheme value literally says "hardcoded" and would need manual replacement for actual use. [MEDIUM]
Other completed criteria
- API key loaded from environment variable via
PostHogEnvenum withProcessInfo.processInfo.environment— follows framework rules exactly - Host correctly configured via environment variable, set to
https://us.i.posthog.comin scheme - Three distinct pbxproj objects created with unique UUIDs (PBXBuildFile, XCSwiftPackageProductDependency, XCRemoteSwiftPackageReference)

PostHog insights and events ⚠️
| Filename | PostHog events | Description |
|---|---|---|
LoginViewModel.swift |
user_logged_in, login_failed, user_logged_out |
Authentication lifecycle: login success with identify, login failure, logout with reset |
FeedViewModel.swift |
post_upvoted, feed_category_changed, post_bookmarked, post_searched |
Core feed interactions: voting, browsing, bookmarking, searching |
CommentsViewModel.swift |
comments_viewed, comment_upvoted |
Comment engagement tracking with post context |
SupportViewModel.swift |
purchase_completed, purchase_failed, purchases_restored |
Monetization funnel: purchase success/failure and restoration |
Issues
- PII in event properties:
user_logged_inandlogin_failedevents include"username": usernameas an event property. The username is already set as a person property viaidentify()— including it again in event properties is redundant and puts PII on individual events rather than the person profile. [MEDIUM]
Other completed criteria
- Events represent real user actions mapped to actual product flows (authentication, content engagement, monetization)
- Events enable product insights — can build login funnels, engagement trends, purchase conversion funnels, search analysis
- Events include relevant contextual properties (post_id, post_title, post_type, result_count, product_id, etc.)
- Event names are descriptive, consistent snake_case convention
