• Potential merge conflict with [POS as a tab i1] Cache POS tab visibility per site for initial value while checking eligibility async #15753, will merge this PR after it.
• Register Tracks events after approval.

Description

This pull request enables POS as a tab i1 feature (moving the POS entry point from the Menu tab to a POS tab for eligible stores with the same eligibility criteria) with analytics in WOOMOB-570. The updates include enabling the POS tab feature flag, adding new analytics events for POS interactions, updating the release notes, and introducing a test to ensure analytics tracking works correctly after eligibility checks.

Feature Flag Changes:

• Modules/Sources/Experiments/DefaultFeatureFlagService.swift: Updated the pointOfSaleAsATabi1 feature flag to always return true, enabling the POS tab for all builds.

Analytics Enhancements:

• WooCommerce/Classes/Analytics/WooAnalyticsStat.swift: Added new analytics events for POS tab interactions, including selection, reselection, and visibility checks.
• WooCommerce/Classes/ViewRelated/MainTabBarController.swift: Integrated analytics tracking for POS tab selection (pointOfSaleTabSelected), reselection (pointOfSaleTabReselected), and visibility checks (pointOfSaleTabVisibilityChecked). [1] [2] [3]

Documentation Updates:

• RELEASE-NOTES.txt: Added a note highlighting the new POS tab feature in the app for eligible stores.

Testing:

• WooCommerce/WooCommerceTests/ViewRelated/MainTabBarControllerTests.swift: Added a unit test to verify that the pointOfSaleTabVisibilityChecked event is tracked correctly after an eligibility check.

Steps to reproduce

🗒️ I haven't been able to trigger the POS tab reselection event, probably because the tab cannot be selected (as a tab item selected state).

Prerequisite: a WPCOM account that has at least two connected stores, one eligible for POS and the other one not eligible.

• Log in to the account in the prerequisite with the store that is eligible for POS --> after the POS tab is shown, an event should be tracked 🔵 Tracked pos_tab_visibility_checked, properties: [is_visible: true, ...]
• Tap on the POS tab twice quickly --> it should launch POS in full-screen with an event tracked 🔵 Tracked main_tab_pos_selected. All following events should have pos_ prefix
• Exit POS
• Go to Menu tab and switch to a store ineligible for POS --> after switching stores, the POS tab should not appear even after a while. An event should be tracked 🔵 Tracked pos_tab_visibility_checked, properties: [is_visible: false, ...]

---

• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.

Works well 👍

As you mentioned, pointOfSaleTabReselected doesn't get tracked, we could skip it entirely with the comment, saying that POS is presented on top of the context and cannot be reselected.

Good point, skipped the reselected event in 844618b. I was still a bit afraid of UX edge cases to be able to trigger the reselection, so I put an assertionFailure that crashes in debug builds and no-op in production builds.

The events aren't shown in Tracks directory yet, I will register them tomorrow or next Monday WOOMOB-624.
