STORY#9-5: Bookings Filtering

[Yalilix]

Story

As a user, I want to filter weekly bookings so that I can quickly find events relevant to me.

Acceptance criteria

Add a filter menu to the Bookings toolbar using the booking data already available.

Supported filters:

• Day of the selected week.
• Building.
• Booking type.
• Room usage/type.
• Minimum room capacity.
• Time of day: morning, afternoon, or evening.

Filtering behaviour:

• Filters apply locally to the currently loaded week without another network request.
• Multiple filter categories combine using AND logic.
• Multiple selections within one category use OR logic.
• Search and filters work together.
• Active filters are clearly indicated.
• Users can remove individual filters or select “Clear all”.
• An empty result shows a filtered-empty state, not the week-empty state.
• Filters reset when leaving the Bookings tab; search behaviour remains unchanged.
• Filter controls include accessibility labels and selected states.

User applies filters

• Input:

  • The user selects one or more filter values.

• Output:

  • The feed immediately shows matching bookings.
  • Existing date grouping and chronological ordering are preserved.
  • The toolbar indicates that filters are active.

No bookings match

• Input:

  • The applied search and filters produce no results.

• Output:

  • The app displays “No bookings match your filters”.
  • The user can clear all filters from the empty state.

Implementation notes

Use the existing WeeklyBooking fields:

• start and end for day/time.
• bookingType.
• buildingID and buildingName.
• usage.
• capacity.

Keep filter state and filtering policy in BookingViewModels, not directly in SwiftUI views. Split the UI into a filter menu, reusable filter sections, and active-filter presentation.

Test plan

• Test every filter independently.
• Test AND/OR combinations.
• Test filters combined with search.
• Test clearing filters and filtered-empty state.
• Confirm filtering does not trigger a GraphQL request.
