What does Product.PurchaseError.ineligibleForOffer mean?

Product.PurchaseError.ineligibleForOffer means the customer is not eligible for the offer that the purchase tried to use.

Quick facts#


Error	`Product.PurchaseError.ineligibleForOffer`
Where	StoreKit 2, Swift (`Product.purchase(options:)`)
Available since	iOS 15.0, iPadOS 15.0, macOS 12.0, tvOS 15.0, watchOS 8.0, visionOS 1.0
What the vendor says	The user is not eligible for the offer.

Cause#

Apple says the App Store treats customers with an existing or expired subscription in the app as eligible for a promotional offer. A customer without one is not eligible (Implementing promotional offers).
Introductory offers have their own rule: isEligibleForIntroOffer is true when the customer is eligible for an introductory offer on the subscription or on any subscription in the same group (isEligibleForIntroOffer).
A customer who already redeemed the introductory offer in that group is no longer eligible.

Fix#

Check eligibility before you show the offer: Product.SubscriptionInfo.isEligibleForIntroOffer for introductory offers, and your own rules plus the customer's subscription history for promotional offers.
Show the standard price when the customer is not eligible, instead of an offer that will fail.
Apple notes that eligibility can be true even when you have not set up an introductory offer, so also check that the offer exists on the product.
Do not retry. The result stays the same until the customer's eligibility changes.

Example#

Swift

import StoreKit

// Ask the App Store whether this customer can get the introductory offer before you advertise it.
func showPrice(for product: Product) async {
    guard let subscription = product.subscription else { return }
    let eligible = await subscription.isEligibleForIntroOffer
    print(eligible ? "Show the introductory offer" : "Show the standard price")
}

func buy(_ product: Product, options: Set<Product.PurchaseOption>) async {
    do {
        _ = try await product.purchase(options: options)
    } catch Product.PurchaseError.ineligibleForOffer {
        print("Not eligible for this offer; fall back to the standard price")
    } catch {
        print("Purchase failed: \(error)")
    }
}
