Apple Family Sharing

Introduction

Apple allows auto-renewable subscriptions and non-consumable in-app purchases to be shared within a family. In order to use this feature, Family Sharing must be enabled on a per purchasable basis. See Turn on Family Sharing for in-app purchases.

Is Family Shareable

The family shareable status of a product is available through the isFamilyShareable field found in the Apple product metadata. The metadata can be obtained from ProductMetadata.GetAppleProductMetadata() via IStoreController.products.

        bool IsProductFamilyShareable(Product product)
        {
            var appleProductMetadata = product.metadata.GetAppleProductMetadata();
            return appleProductMetadata?.isFamilyShareable ?? false;
        }

Revoke Entitlement

In order to be handle revoked entitlements, you can specify a listener through the IAppleConfiguration.SetEntitlementsRevokedListener(Action<List<Product>>. This will be called each time products have been revoked with the list of revoked products.

        void InitializePurchasing()
        {
            var builder = ConfigurationBuilder.Instance(StandardPurchasingModule.Instance());
            builder.Configure<IAppleConfiguration>().SetEntitlementsRevokedListener(EntitlementsRevokeListener);

            UnityPurchasing.Initialize(this, builder);
        }

        void EntitlementsRevokeListener(List<Product> revokedProducts)
        {
            foreach (var revokedProduct in revokedProducts)
            {
                Debug.Log($"Revoked product: {revokedProduct.definition.id}");
            }
        }
