Generation Process

Step 1: Read Templates

Read templates.md for all offer implementation code.

Step 2: Create Core Files

1. SubscriptionOfferManager.swift — Central offer management

   • Offer eligibility checking for all types
   • Offer presentation logic
   • Transaction handling for offer purchases

2. OfferEligibility.swift — Eligibility verification

   • Introductory offer eligibility (isEligibleForIntroOffer)
   • Promotional offer eligibility (your business logic)
   • Win-back offer eligibility (iOS 18+)

3. OfferConfiguration.swift — Offer type definitions and configuration

Step 3: Create UI Files (conditional)

4. OfferBannerView.swift — Contextual offer banners

   • Shows appropriate offer based on user state
   • Introductory offer for new users
   • Promotional offer for at-risk subscribers
   • Win-back offer for churned subscribers

5. OfferCodeRedemptionView.swift — Offer code entry UI (if offer codes selected)

Step 4: Create Optional Files

6. OfferSignatureProvider.swift — Server-side signature handling (if promotional offers)
7. OfferAnalytics.swift — Track offer impression, tap, and conversion events

Step 5: Determine File Location

- If Sources/Store/ exists → Sources/Store/Offers/
- If Store/ exists → Store/Offers/
- If Subscriptions/ exists → Subscriptions/Offers/
- Otherwise → Offers/

Integration Steps

Check Introductory Offer Eligibility:

let manager = SubscriptionOfferManager()
let isEligible = await manager.isEligibleForIntroOffer(
    productID: "com.app.subscription.monthly"
)

Present Best Available Offer:

// Automatically selects the best offer for the user's state
let offer = await manager.bestAvailableOffer(
    for: "com.app.subscription.monthly"
)

// Use with SubscriptionStoreView (iOS 16.4+)
SubscriptionStoreView(groupID: groupID)
    .preferredSubscriptionOffer(offer)

Present Offer Code Sheet:

// iOS 16+
try await AppStore.presentOfferCodeRedeemSheet()

Win-Back Offer (iOS 18+):

let winBackOffers = await manager.availableWinBackOffers(
    for: "com.app.subscription.monthly"
)
if let bestOffer = winBackOffers.first {
    // Present win-back UI
}
