Confirmed — line 104 has lost a tab (2 tabs instead of 3), breaking the indentation pattern. Now I have everything needed. PR Evaluation ReportSummaryThis PR integrates PostHog analytics into a Hacker News iOS client app (Hackers). The SDK (v3.57.3) is added via SPM to the main Xcode project and four feature modules. A

File changes
App sanity check
|
| Criteria | Result | Description |
|---|---|---|
| App builds and runs | No | PostHogConfig(apiKey:) parameter name doesn't match SDK docs (projectToken); pbxproj indentation broken |
| Preserves existing env vars & configs | Yes | Existing code and configs preserved; SupportViewModel if-statement refactored minimally for capture placement |
| No syntax or type errors | No | Wrong parameter name apiKey instead of projectToken in PostHogConfig initializer |
| Correct imports/exports | Yes | All import PostHog statements correct across modules |
| Minimal, focused changes | Yes | All changes directly relate to PostHog integration |
| Pre-existing issues | None | No pre-existing issues observed |
Issues
- Wrong PostHogConfig parameter name:
PostHogConfig(apiKey:host:)is used inHackersApp.swiftbut the PostHog iOS SDK documentation specifiesPostHogConfig(projectToken:host:). Fix: changeapiKey:toprojectToken:. [CRITICAL] - Broken pbxproj indentation: Line 104 in
project.pbxproj— the SwiftSoup framework entry lost a leading tab character (2 tabs instead of 3), breaking the consistent indentation pattern. This may cause Xcode project file parsing issues. [MEDIUM]
Other completed criteria
- Environment variables documented in Xcode scheme with
POSTHOG_PROJECT_TOKENandPOSTHOG_HOST - PostHog SPM dependency correctly added to all four feature Package.swift files
- Package.resolved properly updated with pinned version
- Three required pbxproj objects created (PBXBuildFile, XCSwiftPackageProductDependency, XCRemoteSwiftPackageReference)
PostHog implementation ⚠️
| Criteria | Result | Description |
|---|---|---|
| PostHog SDKs installed | Yes | posthog-ios 3.57.3 added via SPM to main project and all feature modules |
| PostHog client initialized | No | Uses PostHogConfig(apiKey:) instead of PostHogConfig(projectToken:) per docs; lifecycle capture enabled |
| capture() | Yes | 13 meaningful capture calls across authentication, feed, comments, settings, and purchases |
| identify() | Yes | PostHogSDK.shared.identify(username) on login, reset() on logout |
| Error tracking | No | No error/exception tracking configured (no captureException or error tracking setup) |
| Reverse proxy | N/A | iOS native app — reverse proxy only applies to browser JS |
Issues
- Incorrect initialization parameter:
PostHogConfig(apiKey:host:)should bePostHogConfig(projectToken:host:)per the PostHog iOS SDK documentation. [CRITICAL] - No error tracking: The integration does not set up any error/exception tracking. PostHog supports
captureExceptionfor Swift — this should be configured. [MEDIUM]
Other completed criteria
- API key correctly loaded from environment variable via
PostHogEnvenum withfatalErroron missing values - Host configured via environment variable, set to
https://us.i.posthog.comin scheme captureApplicationLifecycleEventsenabled for automatic app lifecycle trackingPostHogSDK.shared.reset()called on logout to unlink device from user- PostHog dependency added to each feature module's Package.swift individually
PostHog insights and events ✅
| Filename | PostHog events | Description |
|---|---|---|
HackersApp.swift |
SDK initialization, lifecycle events | PostHog initialized with lifecycle event capture |
OnboardingCoordinator.swift |
onboarding_completed |
Tracks when user completes onboarding with app version |
LoginViewModel.swift |
user_logged_in, login_failed, user_logged_out |
Full auth flow tracking with identify and reset |
FeedViewModel.swift |
post_upvoted, feed_category_changed, post_bookmarked, search_performed |
Feed engagement with category, query, and result count properties |
CommentsViewModel.swift |
comment_upvoted |
Comment engagement with post and comment context |
SettingsViewModel.swift |
settings_cache_cleared |
Settings action tracking |
SupportViewModel.swift |
support_purchase_completed, support_purchase_failed, support_purchases_restored |
Full purchase funnel with product details |
Issues
- Username as PII in event properties:
user_logged_inandlogin_failedevents include"username": usernamein event properties. Sinceidentify()already sets this as a person property, username should not be duplicated in capture properties. Removeusernamefrom capture properties or move to/. [MEDIUM]
Other completed criteria
- Events represent real user actions (login, vote, search, purchase, bookmark, onboarding)
- Events enable product insights — login funnel, engagement trends, purchase conversion, search effectiveness
- Events include rich contextual properties (post_id, post_title, product_kind, result_count, categories)
- Event names are descriptive and use consistent snake_case convention
