🐛 Mobile | Re-enable Firebase Analytics on iOS

[jernejk]

1. What triggered this change? (PBI link, Email Subject, conversation + reason, etc)

✏️ Today's production pulse report showed that iOS users are invisible to Firebase Analytics / GA4 — every LogEvent() call from iOS has been a silent no-op since PR #1212 (Mar 2025). The iOS branch of RegisterFirebase() never initialised analytics, and the prod GoogleService-Info.plist ships with IS_ANALYTICS_ENABLED=false. Android has been fine throughout.

Pulse report: https://ssw-rewards-prod-today-report-20260423.surge.sh

Verified empirically:

• firebase apps:sdkconfig IOS ... --project ssw-rewards-52a58 → IS_ANALYTICS_ENABLED=false
• src/MobileUI/MauiProgram.cs (current main) only calls FirebaseAnalyticsImplementation.Initialize(activity) under #elif ANDROID. The #if IOS block has no analytics init.
• No programmatic overrides anywhere in the codebase (no SetAnalyticsCollectionEnabled, no FIREBASE_ANALYTICS_COLLECTION_ENABLED in Info.plist).

2. What was changed?

✏️ Single-file change in src/MobileUI/MauiProgram.cs:

• Moved using Plugin.Firebase.Analytics; out of the #elif ANDROID block so iOS can use it too.
• Added one line inside the iOS WillFinishLaunching lifecycle event:

  // Override IS_ANALYTICS_ENABLED=false that ships in the prod plist.
  CrossFirebaseAnalytics.Current.IsAnalyticsCollectionEnabled = true;

That property setter delegates to FirebaseAnalytics.SetAnalyticsCollectionEnabled(true) under the hood (confirmed from Plugin.Firebase iOS source), which takes precedence over the plist flag at runtime. No need to regenerate the production GoogleService-Info.plist — though it would still be good hygiene to do so separately so the plist reflects intent.

Android is untouched — it already works via FirebaseAnalyticsImplementation.Initialize(activity) + manifest flag.

Validation plan

• TestFlight build, open the app on iOS, trigger quiz_start + reward_view
• Confirm events appear in Firebase Console → Analytics → DebugView (or Realtime) within ~1 minute
• Confirm Android still flows events as before
• (Follow-up, not this PR) regenerate prod iOS GoogleService-Info.plist from Firebase Console with analytics enabled, update the GitHub secret that release workflows inject from

3. Did you do pair or mob programming?

✏️ Paired with Claude Opus 4.7 (1M context) — investigation (git archaeology on PR #1212), Plugin.Firebase source reading, and the fix itself.

Pull request overview

Re-enables Firebase Analytics event collection on iOS by explicitly enabling analytics at runtime during app startup, addressing the current “silent no-op” behavior caused by an iOS plist flag and missing iOS-side enablement.

Changes:

• Makes Plugin.Firebase.Analytics available for iOS by moving the using directive out of the Android-only preprocessor block.
• Enables Firebase Analytics collection on iOS during WillFinishLaunching via CrossFirebaseAnalytics.Current.IsAnalyticsCollectionEnabled = true;.

LGTM - I am curious, will this be shipped immediately?
