# Custom Itinerary Items Implementation Plan

> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.

**Goal:** Allow users to add, edit, reorder, and delete custom items (restaurants, hotels, activities, notes) within saved trip itineraries, with CloudKit sync.

**Architecture:** Domain model with anchor-based positioning, CloudKit wrapper following CKPollVote pattern, CustomItemService actor for CRUD, SwiftData for local cache, UI integration in TripDetailView with drag/drop.

**Tech Stack:** Swift, SwiftUI, SwiftData, CloudKit, draggable/dropDestination APIs

## Task 1: Domain Model

**Files:**
- Create: `SportsTime/Core/Models/Domain/CustomItineraryItem.swift`
- Test: `SportsTimeTests/Domain/CustomItineraryItemTests.swift`

**Step 1: Create the domain model file**

```swift
//
//  CustomItineraryItem.swift
//  SportsTime
//

import Foundation

struct CustomItineraryItem: Identifiable, Codable, Hashable {
    let id: UUID
    let tripId: UUID
    var category: ItemCategory
    var title: String
    var anchorType: AnchorType
    var anchorId: String?
    var anchorDay: Int
    let createdAt: Date
    var modifiedAt: Date

    init(
        id: UUID = UUID(),
        tripId: UUID,
        category: ItemCategory,
        title: String,
        anchorType: AnchorType = .startOfDay,
        anchorId: String? = nil,
        anchorDay: Int,
        createdAt: Date = Date(),
        modifiedAt: Date = Date()
    ) {
        self.id = id
        self.tripId = tripId
        self.category = category
        self.title = title
        self.anchorType = anchorType
        self.anchorId = anchorId
        self.anchorDay = anchorDay
        self.createdAt = createdAt
        self.modifiedAt = modifiedAt
    }

    enum ItemCategory: String, Codable, CaseIterable {
        case restaurant
        case hotel
        case activity
        case note

        var icon: String {
            switch self {
            case .restaurant: return "🍽️"
            case .hotel: return "🏨"
            case .activity: return "🎯"
            case .note: return "📝"
            }
        }

        var label: String {
            switch self {
            case .restaurant: return "Restaurant"
            case .hotel: return "Hotel"
            case .activity: return "Activity"
            case .note: return "Note"
            }
        }

        var systemImage: String {
            switch self {
            case .restaurant: return "fork.knife"
            case .hotel: return "bed.double.fill"
            case .activity: return "figure.run"
            case .note: return "note.text"
            }
        }
    }

    enum AnchorType: String, Codable {
        case startOfDay
        case afterGame
        case afterTravel
    }
}
```

**Step 2: Create basic unit tests**

```swift
//
//  CustomItineraryItemTests.swift
//  SportsTimeTests
//

import Testing
@testable import SportsTime
import Foundation

struct CustomItineraryItemTests {

    @Test("Item initializes with default values")
    func item_InitializesWithDefaults() {
        let tripId = UUID()
        let item = CustomItineraryItem(
            tripId: tripId,
            category: .restaurant,
            title: "Joe's BBQ",
            anchorDay: 1
        )

        #expect(item.tripId == tripId)
        #expect(item.category == .restaurant)
        #expect(item.title == "Joe's BBQ")
        #expect(item.anchorType == .startOfDay)
        #expect(item.anchorId == nil)
        #expect(item.anchorDay == 1)
    }

    @Test("Item category has correct icons")
    func category_HasCorrectIcons() {
        #expect(CustomItineraryItem.ItemCategory.restaurant.icon == "🍽️")
        #expect(CustomItineraryItem.ItemCategory.hotel.icon == "🏨")
        #expect(CustomItineraryItem.ItemCategory.activity.icon == "🎯")
        #expect(CustomItineraryItem.ItemCategory.note.icon == "📝")
    }

    @Test("Item is Codable")
    func item_IsCodable() throws {
        let item = CustomItineraryItem(
            tripId: UUID(),
            category: .hotel,
            title: "Hilton Downtown",
            anchorType: .afterGame,
            anchorId: "game_123",
            anchorDay: 2
        )

        let encoded = try JSONEncoder().encode(item)
        let decoded = try JSONDecoder().decode(CustomItineraryItem.self, from: encoded)

        #expect(decoded.id == item.id)
        #expect(decoded.title == item.title)
        #expect(decoded.anchorType == .afterGame)
        #expect(decoded.anchorId == "game_123")
    }
}
```

**Step 3: Run tests to verify**

Run: `xcodebuild -project SportsTime.xcodeproj -scheme SportsTime -destination 'platform=iOS Simulator,name=iPhone 17,OS=26.2' -only-testing:SportsTimeTests/CustomItineraryItemTests test`
Expected: PASS

**Step 4: Commit**

```bash
git add SportsTime/Core/Models/Domain/CustomItineraryItem.swift SportsTimeTests/Domain/CustomItineraryItemTests.swift

Find the `CKRecordType` extension and add:

```swift
static let customItineraryItem: CKRecordType = "CustomItineraryItem"
```

**Step 2: Add CKCustomItineraryItem struct**

Add at the end of CKModels.swift:

```swift
// MARK: - CKCustomItineraryItem

struct CKCustomItineraryItem {
    static let itemIdKey = "itemId"
    static let tripIdKey = "tripId"
    static let categoryKey = "category"
    static let titleKey = "title"
    static let anchorTypeKey = "anchorType"
    static let anchorIdKey = "anchorId"
    static let anchorDayKey = "anchorDay"
    static let createdAtKey = "createdAt"
    static let modifiedAtKey = "modifiedAt"

    let record: CKRecord

    init(record: CKRecord) {
        self.record = record
    }

    init(item: CustomItineraryItem) {
        let record = CKRecord(
            recordType: CKRecordType.customItineraryItem,
            recordID: CKRecord.ID(recordName: item.id.uuidString)
        )
        record[CKCustomItineraryItem.itemIdKey] = item.id.uuidString
        record[CKCustomItineraryItem.tripIdKey] = item.tripId.uuidString
        record[CKCustomItineraryItem.categoryKey] = item.category.rawValue
        record[CKCustomItineraryItem.titleKey] = item.title
        record[CKCustomItineraryItem.anchorTypeKey] = item.anchorType.rawValue
        record[CKCustomItineraryItem.anchorIdKey] = item.anchorId
        record[CKCustomItineraryItem.anchorDayKey] = item.anchorDay
        record[CKCustomItineraryItem.createdAtKey] = item.createdAt
        record[CKCustomItineraryItem.modifiedAtKey] = item.modifiedAt
        self.record = record
    }

    func toItem() -> CustomItineraryItem? {
        guard let itemIdString = record[CKCustomItineraryItem.itemIdKey] as? String,
              let itemId = UUID(uuidString: itemIdString),
              let tripIdString = record[CKCustomItineraryItem.tripIdKey] as? String,
              let tripId = UUID(uuidString: tripIdString),
              let categoryString = record[CKCustomItineraryItem.categoryKey] as? String,
              let category = CustomItineraryItem.ItemCategory(rawValue: categoryString),
              let title = record[CKCustomItineraryItem.titleKey] as? String,
              let anchorTypeString = record[CKCustomItineraryItem.anchorTypeKey] as? String,
              let anchorType = CustomItineraryItem.AnchorType(rawValue: anchorTypeString),
              let anchorDay = record[CKCustomItineraryItem.anchorDayKey] as? Int,
              let createdAt = record[CKCustomItineraryItem.createdAtKey] as? Date,
              let modifiedAt = record[CKCustomItineraryItem.modifiedAtKey] as? Date
        else { return nil }

        let anchorId = record[CKCustomItineraryItem.anchorIdKey] as? String

        return CustomItineraryItem(
            id: itemId,
            tripId: tripId,
            category: category,
            title: title,
            anchorType: anchorType,
            anchorId: anchorId,
            anchorDay: anchorDay,
            createdAt: createdAt,
            modifiedAt: modifiedAt
        )
    }
}
```

**Step 3: Build to verify**

## Task 6: CustomItemRow UI

**Files:**
- Create: `SportsTime/Features/Trip/Views/CustomItemRow.swift`

**Step 1: Create the row component**

```swift
//
//  CustomItemRow.swift
//  SportsTime
//
//  Row component for custom itinerary items with drag handle
//

import SwiftUI

struct CustomItemRow: View {
    @Environment(\.colorScheme) private var colorScheme

    let item: CustomItineraryItem
    var onTap: () -> Void
    var onDelete: () -> Void

    /*
    REORDERING OPTIONS (for future reference):
    1. Edit mode toggle - User taps "Edit" to show drag handles, then "Done" (like Reminders)
    2. Long-press to drag - No edit mode, just long-press and drag
    3. Always show handles - Custom items always have visible drag handle (CURRENT CHOICE)
    */

    var body: some View {
        HStack(spacing: 12) {
            // Category icon
            Text(item.category.icon)
                .font(.title3)

            // Title
            Text(item.title)
                .font(.subheadline)
                .lineLimit(2)

            Spacer()

            // Drag handle - always visible
            Image(systemName: "line.3.horizontal")
                .foregroundStyle(.secondary)
                .font(.subheadline)
        }
        .padding(.horizontal, Theme.Spacing.md)
        .padding(.vertical, Theme.Spacing.sm)
        .background(Theme.warmOrange.opacity(0.08))
        .cornerRadius(8)
        .contentShape(Rectangle())
        .onTapGesture {
            onTap()
        }
        .swipeActions(edge: .trailing, allowsFullSwipe: true) {
            Button(role: .destructive) {
                onDelete()
            } label: {
                Label("Delete", systemImage: "trash")
            }
        }
    }
}

#Preview {
    VStack {
        CustomItemRow(
            item: CustomItineraryItem(
                tripId: UUID(),
                category: .restaurant,
                title: "Joe's BBQ - Best brisket in Texas!",
                anchorDay: 1
            ),
            onTap: {},
            onDelete: {}
        )
        CustomItemRow(
            item: CustomItineraryItem(
                tripId: UUID(),
                category: .hotel,
                title: "Hilton Downtown",
                anchorDay: 1
            ),
            onTap: {},
            onDelete: {}
        )
    }
    .padding()
}
```

**Step 2: Build to verify**

Run: `xcodebuild -project SportsTime.xcodeproj -scheme SportsTime -destination 'platform=iOS Simulator,name=iPhone 17,OS=26.2' build`
Expected: BUILD SUCCEEDED

**Step 3: Commit**

```bash
git add SportsTime/Features/Trip/Views/CustomItemRow.swift
git commit -m "feat(ui): add CustomItemRow with drag handle and swipe-to-delete"
```

---

## Task 7: TripDetailView Integration - Part 1 (State & Data Loading)

**Files:**
- Modify: `SportsTime/Features/Trip/Views/TripDetailView.swift`

**Step 1: Add state properties**

Add these state properties near the existing `@State` declarations:

```swift
@State private var customItems: [CustomItineraryItem] = []
@State private var showAddItemSheet = false
@State private var editingItem: CustomItineraryItem?
@State private var addItemAnchor: (day: Int, type: CustomItineraryItem.AnchorType, id: String?)? = nil
```

**Step 2: Add loadCustomItems function**

Add this function in the view:

```swift
private func loadCustomItems() async {
    guard let tripId = trip.id as UUID? else { return }
    do {
        customItems = try await CustomItemService.shared.fetchItems(forTripId: tripId)
    } catch {
        print("Failed to load custom items: \(error)")
    }
}
```

**Step 3: Add task modifier to load items**

In the body, add a `.task` modifier after the existing `.onAppear`:

```swift
.task {
    await loadCustomItems()
}
```

**Step 4: Build to verify**

Run: `xcodebuild -project SportsTime.xcodeproj -scheme SportsTime -destination 'platform=iOS Simulator,name=iPhone 17,OS=26.2' build`
Expected: BUILD SUCCEEDED

**Step 5: Commit**

```bash
git add SportsTime/Features/Trip/Views/TripDetailView.swift
git commit -m "feat(ui): add custom items state and loading to TripDetailView"
```

---

## Task 8: TripDetailView Integration - Part 2 (Inline Add Buttons)

**Files:**
- Modify: `SportsTime/Features/Trip/Views/TripDetailView.swift`

**Step 1: Create InlineAddButton component**

Add this private struct inside or near TripDetailView:

```swift
private struct InlineAddButton: View {
    let action: () -> Void

    var body: some View {
        Button(action: action) {
            HStack {
                Image(systemName: "plus.circle.fill")
                    .foregroundStyle(Theme.warmOrange.opacity(0.6))
                Text("Add")
                    .font(.caption)
                    .foregroundStyle(.secondary)
            }
            .padding(.vertical, 4)
            .padding(.horizontal, 8)
        }
        .buttonStyle(.plain)
    }
}
```

**Step 2: Update ItinerarySection enum**

Find the `ItinerarySection` enum and add a new case:

```swift
enum ItinerarySection {
    case day(dayNumber: Int, date: Date, games: [RichGame])
    case travel(TravelSegment)
    case customItem(CustomItineraryItem)
    case addButton(day: Int, anchorType: CustomItineraryItem.AnchorType, anchorId: String?)
}
```

**Step 3: Build to verify**

Run: `xcodebuild -project SportsTime.xcodeproj -scheme SportsTime -destination 'platform=iOS Simulator,name=iPhone 17,OS=26.2' build`
Expected: BUILD SUCCEEDED (may have warnings about unhandled cases - fix in next task)

**Step 4: Commit**

```bash
git add SportsTime/Features/Trip/Views/TripDetailView.swift
git commit -m "feat(ui): add InlineAddButton and update ItinerarySection enum"
```

---

## Task 9: TripDetailView Integration - Part 3 (Rendering Custom Items)

**Files:**
- Modify: `SportsTime/Features/Trip/Views/TripDetailView.swift`

**Step 1: Update itinerarySections to include custom items and add buttons**

Replace the `itinerarySections` computed property to interleave custom items and add buttons. This is complex - the key is to:
1. For each day section, insert custom items anchored to that day
2. After each game/travel, insert any custom items anchored to it
3. Insert add buttons in the gaps

```swift
private var itinerarySections: [ItinerarySection] {
    var sections: [ItinerarySection] = []
    var dayCitySections: [(dayNumber: Int, date: Date, city: String, games: [RichGame])] = []
    let days = tripDays

    for (index, dayDate) in days.enumerated() {
        let dayNum = index + 1
        let gamesOnDay = gamesOn(date: dayDate)

        guard !gamesOnDay.isEmpty else { continue }

        var gamesByCity: [(city: String, games: [RichGame])] = []
        for game in gamesOnDay {
            let city = game.stadium.city
            if let lastIndex = gamesByCity.indices.last, gamesByCity[lastIndex].city == city {
                gamesByCity[lastIndex].games.append(game)
            } else {
                gamesByCity.append((city, [game]))
            }
        }

        for cityGroup in gamesByCity {
            dayCitySections.append((dayNum, dayDate, cityGroup.city, cityGroup.games))
        }
    }

    for (index, section) in dayCitySections.enumerated() {
        // Travel before this section
        if index > 0 {
            let prevSection = dayCitySections[index - 1]
            if prevSection.city != section.city {
                if let travelSegment = findTravelSegment(from: prevSection.city, to: section.city) {
                    sections.append(.travel(travelSegment))
                    // Add button after travel
                    sections.append(.addButton(day: section.dayNumber, anchorType: .afterTravel, anchorId: travelSegment.id.uuidString))
                    // Custom items after this travel
                    let itemsAfterTravel = customItems.filter {
                        $0.anchorDay == section.dayNumber &&
                        $0.anchorType == .afterTravel &&
                        $0.anchorId == travelSegment.id.uuidString
                    }
                    for item in itemsAfterTravel {
                        sections.append(.customItem(item))
                    }
                }
            }
        }

        // Add button at start of day (before games)
        sections.append(.addButton(day: section.dayNumber, anchorType: .startOfDay, anchorId: nil))

        // Custom items at start of day
        let itemsAtStart = customItems.filter {
            $0.anchorDay == section.dayNumber && $0.anchorType == .startOfDay
        }
        for item in itemsAtStart {
            sections.append(.customItem(item))
        }

        // Day section
        sections.append(.day(dayNumber: section.dayNumber, date: section.date, games: section.games))

        // Add button after day's games
        if let lastGame = section.games.last {
            sections.append(.addButton(day: section.dayNumber, anchorType: .afterGame, anchorId: lastGame.game.id))
            // Custom items after this game
            let itemsAfterGame = customItems.filter {
                $0.anchorDay == section.dayNumber &&
                $0.anchorType == .afterGame &&
                $0.anchorId == lastGame.game.id
            }
            for item in itemsAfterGame {
                sections.append(.customItem(item))
            }
        }
    }

    return sections
}
```

**Step 2: Update the ForEach in itinerarySection to handle new cases**

Find where `itinerarySections` is rendered and update the switch:

```swift
ForEach(Array(itinerarySections.enumerated()), id: \.offset) { index, section in
    switch section {
    case .day(let dayNumber, let date, let games):
        DaySection(
            dayNumber: dayNumber,
            date: date,
            games: games,
            trip: trip,
            colorScheme: colorScheme
        )
        .staggeredAnimation(index: index)
    case .travel(let segment):
        TravelSection(segment: segment)
            .staggeredAnimation(index: index)
    case .customItem(let item):
        CustomItemRow(
            item: item,
            onTap: { editingItem = item },
            onDelete: { Task { await deleteItem(item) } }
        )
        .staggeredAnimation(index: index)
    case .addButton(let day, let anchorType, let anchorId):
        InlineAddButton {
            addItemAnchor = (day, anchorType, anchorId)
            showAddItemSheet = true
        }
    }
}
```

**Step 3: Build to verify**

Run: `xcodebuild -project SportsTime.xcodeproj -scheme SportsTime -destination 'platform=iOS Simulator,name=iPhone 17,OS=26.2' build`
Expected: BUILD SUCCEEDED (may need to add missing functions in next task)

**Step 4: Commit**

```bash
git add SportsTime/Features/Trip/Views/TripDetailView.swift
git commit -m "feat(ui): render custom items and add buttons in itinerary"
```

## Task 10: TripDetailView Integration - Part 4 (CRUD Operations & Sheets)

**Files:**
- Modify: `SportsTime/Features/Trip/Views/TripDetailView.swift`

**Step 1: Add CRUD helper functions**

```swift
private func saveItem(_ item: CustomItineraryItem) async {
    do {
        if customItems.contains(where: { $0.id == item.id }) {
            // Update existing
            let updated = try await CustomItemService.shared.updateItem(item)
            if let index = customItems.firstIndex(where: { $0.id == updated.id }) {
                customItems[index] = updated
            }
        } else {
            // Create new
            let created = try await CustomItemService.shared.createItem(item)
            customItems.append(created)
        }
    } catch {
        print("Failed to save item: \(error)")
    }
}

private func deleteItem(_ item: CustomItineraryItem) async {
    do {
        try await CustomItemService.shared.deleteItem(item.id)
        customItems.removeAll { $0.id == item.id }
    } catch {
        print("Failed to delete item: \(error)")
    }
}
```

**Step 2: Add sheet modifiers**

Add these modifiers to the view body:

```swift
.sheet(isPresented: $showAddItemSheet) {
    if let anchor = addItemAnchor {
        AddItemSheet(
            tripId: trip.id,
            anchorDay: anchor.day,
            anchorType: anchor.type,
            anchorId: anchor.id,
            existingItem: nil
        ) { item in
            Task { await saveItem(item) }
        }
    }
}
.sheet(item: $editingItem) { item in
    AddItemSheet(
        tripId: trip.id,
        anchorDay: item.anchorDay,
        anchorType: item.anchorType,
        anchorId: item.anchorId,
        existingItem: item
    ) { updatedItem in
        Task { await saveItem(updatedItem) }
    }
}
```

**Step 3: Build to verify**

Run: `xcodebuild -project SportsTime.xcodeproj -scheme SportsTime -destination 'platform=iOS Simulator,name=iPhone 17,OS=26.2' build`
Expected: BUILD SUCCEEDED

**Step 4: Commit**

```bash
git add SportsTime/Features/Trip/Views/TripDetailView.swift
git commit -m "feat(ui): add CRUD operations and sheets for custom items"
```

## Task 11: Drag and Drop (Optional Enhancement)

**Files:**
- Modify: `SportsTime/Features/Trip/Views/TripDetailView.swift`
- Modify: `SportsTime/Features/Trip/Views/CustomItemRow.swift`

**Note:** This task adds drag-and-drop reordering. It can be deferred if basic add/edit/delete is sufficient for now.

**Step 1: Make CustomItemRow draggable**

Update CustomItemRow to add `.draggable`:

```swift
var body: some View {
    HStack(spacing: 12) {
        // ... existing content
    }
    // ... existing modifiers
    .draggable(item.id.uuidString) {
        // Drag preview
        HStack {
            Text(item.category.icon)
            Text(item.title)
        }
        .padding(8)
        .background(Theme.cardBackground(.dark))
        .cornerRadius(8)
    }
}
```

**Step 2: Add drop destinations to add buttons**

Update InlineAddButton:

```swift
private struct InlineAddButton: View {
    let day: Int
    let anchorType: CustomItineraryItem.AnchorType
    let anchorId: String?
    let onAdd: () -> Void
    let onDrop: (CustomItineraryItem.AnchorType, String?, Int) -> Void

    var body: some View {
        Button(action: onAdd) {
            // ... existing content
        }
        .dropDestination(for: String.self) { items, _ in
            guard let itemIdString = items.first else { return false }
            onDrop(anchorType, anchorId, day)
            return true
        }
    }
}
```

**Step 3: Implement move logic**

Add function to handle drops:

```swift
private func moveItem(itemId: String, toAnchorType: CustomItineraryItem.AnchorType, toAnchorId: String?, toDay: Int) async {
    guard let uuid = UUID(uuidString: itemId),
          var item = customItems.first(where: { $0.id == uuid }) else { return }

    item.anchorType = toAnchorType
    item.anchorId = toAnchorId
    item.anchorDay = toDay
    item.modifiedAt = Date()

    await saveItem(item)
}
```

**Step 4: Build and test**

Run: `xcodebuild -project SportsTime.xcodeproj -scheme SportsTime -destination 'platform=iOS Simulator,name=iPhone 17,OS=26.2' build`
Expected: BUILD SUCCEEDED

**Step 5: Commit**

```bash
git add SportsTime/Features/Trip/Views/TripDetailView.swift SportsTime/Features/Trip/Views/CustomItemRow.swift
git commit -m "feat(ui): add drag-and-drop reordering for custom items"
```

---

## Task 12: Final Integration Test

**Step 1: Run full test suite**

Run: `xcodebuild -project SportsTime.xcodeproj -scheme SportsTime -destination 'platform=iOS Simulator,name=iPhone 17,OS=26.2' test`
Expected: All tests PASS

**Step 2: Manual testing checklist**

- [ ] Open a saved trip
- [ ] Tap "+ Add" button between items
- [ ] Select category and enter title
- [ ] Verify item appears in correct position
- [ ] Tap item to edit
- [ ] Swipe left to delete
- [ ] (If drag implemented) Drag item to new position
- [ ] Close and reopen trip - items persist
- [ ] Test on second device - items sync via CloudKit

**Step 3: Final commit**

```bash
git add -A
git commit -m "feat: complete custom itinerary items feature"
```
