# In-App Purchase Implementation Plan

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

**Goal:** Implement freemium subscription model with StoreKit 2 local-only entitlement checking.

**Architecture:** StoreManager singleton manages entitlements via `Transaction.currentEntitlements`. ProGate view modifier gates Pro features. PaywallView handles purchases.

**Tech Stack:** StoreKit 2, SwiftUI, @Observable

## Task 1: Create StoreKit Configuration File

**Files:**
- Create: `SportsTime/SportsTime.storekit`

**Step 1: Create StoreKit configuration file in Xcode**

Open Xcode → File → New → File → StoreKit Configuration File

Name it `SportsTime.storekit` and save to project root.

**Step 2: Add subscription group**

In the StoreKit file, click "+" → Add Subscription Group → Name: "Pro Access"

**Step 3: Add monthly subscription**

Inside "Pro Access" group, click "+" → Add Subscription:
- Reference Name: "Pro Monthly"
- Product ID: `com.sportstime.pro.monthly`
- Price: $4.99
- Duration: 1 Month
- Family Sharing: Enabled

**Step 4: Add annual subscription**

Inside "Pro Access" group, click "+" → Add Subscription:
- Reference Name: "Pro Annual"
- Product ID: `com.sportstime.pro.annual`
- Price: $49.99
- Duration: 1 Year
- Family Sharing: Enabled

**Step 5: Configure scheme to use StoreKit config**

Edit Scheme → Run → Options → StoreKit Configuration → Select `SportsTime.storekit`

## Task 2: Create ProFeature Enum

**Files:**
- Create: `SportsTime/SportsTime/Core/Store/ProFeature.swift`
- Create: `SportsTime/SportsTimeTests/Store/ProFeatureTests.swift`

**Step 1: Write the test**

Create `SportsTime/SportsTimeTests/Store/ProFeatureTests.swift`:

```swift
//
//  ProFeatureTests.swift
//  SportsTimeTests
//

import Testing
@testable import SportsTime

struct ProFeatureTests {
    @Test func allCases_containsExpectedFeatures() {
        let features = ProFeature.allCases
        #expect(features.contains(.unlimitedTrips))
        #expect(features.contains(.pdfExport))
        #expect(features.contains(.progressTracking))
        #expect(features.count == 3)
    }

    @Test func displayName_returnsHumanReadableString() {
        #expect(ProFeature.unlimitedTrips.displayName == "Unlimited Trips")
        #expect(ProFeature.pdfExport.displayName == "PDF Export")
        #expect(ProFeature.progressTracking.displayName == "Progress Tracking")
    }

    @Test func description_returnsMarketingCopy() {

        #expect(!ProFeature.pdfExport.icon.isEmpty)
        #expect(!ProFeature.progressTracking.icon.isEmpty)
    }
}
```

**Step 2: Write implementation**

Create `SportsTime/SportsTime/Core/Store/ProFeature.swift`:

```swift
//
//  ProFeature.swift

//
//  Defines features gated behind Pro subscription.
//

import Foundation

enum ProFeature: String, CaseIterable, Identifiable {
    case unlimitedTrips
    case pdfExport

    var id: String { rawValue }

    var displayName: String {
        switch self {
        case .unlimitedTrips: return "Unlimited Trips"
        case .pdfExport: return "PDF Export"
        case .progressTracking: return "Progress Tracking"
        }
    }

    var description: String {
        switch self {
        case .unlimitedTrips:
            return "Save unlimited trips and never lose your itineraries."
        case .pdfExport:
            return "Export beautiful PDF itineraries to share with friends."
        case .progressTracking:
            return "Track stadium visits, earn badges, complete your bucket list."
        }
    }

    var icon: String {
        switch self {
        case .unlimitedTrips: return "suitcase.fill"
        case .pdfExport: return "doc.fill"
        case .progressTracking: return "trophy.fill"
        }
    }
}
```

## Task 7: Create ProGate View Modifier

**Files:**
- Create: `SportsTime/SportsTime/Features/Paywall/ViewModifiers/ProGate.swift`
- Create: `SportsTime/SportsTimeTests/Store/ProGateTests.swift`

**Step 1: Write the test**

Create `SportsTime/SportsTimeTests/Store/ProGateTests.swift`:

```swift
//
//  ProGateTests.swift
//  SportsTimeTests
//

import Testing
import SwiftUI
@testable import SportsTime

struct ProGateTests {
    @Test func proGate_createsViewModifier() {
        // Just verify the modifier compiles and can be applied
        let _ = Text("Test").proGate(feature: .pdfExport)
        #expect(true) // If we got here, it compiles
    }
}
```

**Step 2: Write implementation**

Create `SportsTime/SportsTime/Features/Paywall/ViewModifiers/ProGate.swift`:

```swift
//
//  ProGate.swift
//  SportsTime
//
//  View modifier that gates Pro-only features.
//

import SwiftUI

## Task 9: Integrate StoreManager in App Lifecycle

**Files:**
- Modify: `SportsTime/SportsTime/SportsTimeApp.swift`

**Step 1: Add transaction listener property and initialization**

In `SportsTimeApp.swift`, add after `sharedModelContainer` (around line 45):

```swift
    /// Task that listens for StoreKit transaction updates
    private var transactionListener: Task<Void, Never>?

    init() {
        // Start listening for transactions immediately
        transactionListener = StoreManager.shared.listenForTransactions()
    }
```

**Step 2: Update BootstrappedContentView to load store data**

In `performBootstrap()` function around line 95, add store initialization after `AppDataProvider.shared.loadInitialData()`:

```swift
            // 3. Load data from SwiftData into memory
            await AppDataProvider.shared.loadInitialData()

            // 4. Load store products and entitlements
            await StoreManager.shared.loadProducts()
            await StoreManager.shared.updateEntitlements()

            // 5. App is now usable
            isBootstrapping = false
```

**Step 3: Add onboarding paywall state**

In `BootstrappedContentView`, add state property:

```swift
    @State private var showOnboardingPaywall = false

    private var shouldShowOnboardingPaywall: Bool {
        !UserDefaults.standard.bool(forKey: "hasSeenOnboardingPaywall") && !StoreManager.shared.isPro
    }
```

**Step 4: Show onboarding paywall after bootstrap**

Update the `body` to show onboarding paywall:

```swift
            } else {
                HomeView()
                    .sheet(isPresented: $showOnboardingPaywall) {
                        OnboardingPaywallView(isPresented: $showOnboardingPaywall)
                            .interactiveDismissDisabled()
                    }
                    .onAppear {
                        if shouldShowOnboardingPaywall {
                            showOnboardingPaywall = true
                        }
                    }
            }
```

## Task 10: Gate Trip Saving

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

**Step 1: Add saved trip count query**

At the top of `TripDetailView`, add after existing `@State` properties (around line 27):

```swift
    @Query private var savedTrips: [SavedTrip]
```

**Step 2: Add paywall state**

Add state for showing paywall:

```swift
    @State private var showProPaywall = false
```

**Step 3: Modify saveTrip function**

Replace the `saveTrip()` function (around line 525) with gated version:

```swift
    private func saveTrip() {
        // Check trip limit for free users
        if !StoreManager.shared.isPro && savedTrips.count >= StoreManager.freeTripLimit {
            showProPaywall = true
            return
        }

        guard let savedTrip = SavedTrip.from(trip, games: games, status: .planned) else {
            return
        }

        modelContext.insert(savedTrip)

        do {
            try modelContext.save()
            withAnimation(.spring(response: 0.3, dampingFraction: 0.6)) {
                isSaved = true
            }
        } catch {
            // Save failed silently
        }
    }
```

**Step 4: Add paywall sheet**

Add sheet modifier to the view body (after existing sheets around line 93):

```swift
        .sheet(isPresented: $showProPaywall) {
            PaywallView()
        }
```

---

## Task 11: Gate PDF Export

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

```swift
                Button {
                    if StoreManager.shared.isPro {
                        Task {
                            await exportPDF()
                        }
                    } else {
                        showProPaywall = true
                    }
                } label: {
                    HStack(spacing: 2) {
                        Image(systemName: "doc.fill")
                        if !StoreManager.shared.isPro {
                            ProBadge()
                        }
                    }
                    .foregroundStyle(Theme.warmOrange)
                }
```

## Task 12: Gate Progress Tracking Tab

**Files:**
- Modify: `SportsTime/SportsTime/Features/Home/Views/HomeView.swift`

**Step 1: Add paywall state to HomeView**

Add state property in HomeView (around line 19):

```swift
    @State private var showProPaywall = false
```

**Step 2: Modify Progress tab to show paywall for free users**

Replace the Progress tab section (around line 86) with:

```swift
            // Progress Tab
            NavigationStack {
                if StoreManager.shared.isPro {
                    ProgressTabView()
                } else {
                    ProLockedView(feature: .progressTracking) {
                        showProPaywall = true
                    }
                }
            }
            .tabItem {
                Label("Progress", systemImage: "chart.bar.fill")
            }
            .tag(3)
```

// MARK: - Pro Locked View

struct ProLockedView: View {
    let feature: ProFeature
    let onUnlock: () -> Void

    @Environment(\.colorScheme) private var colorScheme

    var body: some View {
        VStack(spacing: Theme.Spacing.xl) {
            Spacer()

            ZStack {
                Circle()
                    .fill(Theme.warmOrange.opacity(0.15))
                    .frame(width: 100, height: 100)

                Image(systemName: "lock.fill")
                    .font(.system(size: 40))
                    .foregroundStyle(Theme.warmOrange)
            }

            VStack(spacing: Theme.Spacing.sm) {
                Text(feature.displayName)
                    .font(.title2.bold())
                    .foregroundStyle(Theme.textPrimary(colorScheme))

                Text(feature.description)
                    .font(.body)
                    .foregroundStyle(Theme.textSecondary(colorScheme))
                    .multilineTextAlignment(.center)
                    .padding(.horizontal, Theme.Spacing.xl)
            }

            Button {
                onUnlock()
            } label: {
                HStack {
                    Image(systemName: "star.fill")
                    Text("Upgrade to Pro")
                }
                .fontWeight(.semibold)
                .frame(maxWidth: .infinity)
                .padding(Theme.Spacing.md)
                .background(Theme.warmOrange)
                .foregroundStyle(.white)
                .clipShape(RoundedRectangle(cornerRadius: Theme.CornerRadius.medium))
            }
            .padding(.horizontal, Theme.Spacing.xl)

            Spacer()

- [ ] Can save 1 trip as free user
- [ ] Saving 2nd trip shows paywall
- [ ] PDF export button shows PRO badge for free users
- [ ] Tapping PDF shows paywall
- [ ] Settings shows "Upgrade to Pro" for free users
- [ ] Settings shows "Manage Subscription" for Pro users
- [ ] Restore Purchases works

**Step 4: Commit all changes**

```bash
git add -A
git commit -m "feat(iap): complete In-App Purchase implementation

- StoreKit 2 configuration with monthly/annual subscriptions
- StoreManager singleton for entitlement checking
- PaywallView with pricing options
- OnboardingPaywallView for first-launch upsell
- ProGate view modifier for feature gating
- Trip saving limited to 1 for free users
