VaultKit

StoreKit2 interface focused on on-device validation of renewables/non-renewables.

Create StoreKit.config file

https://developer.apple.com/documentation/xcode/setting-up-storekit-testing-in-xcode

To create a StoreKit configuration file:

1. Launch Xcode, then choose File > New > File.

2. In the sheet that appears, enter storekit in the Filter search field.

3. Select StoreKit Configuration File, then click Next.

4. In the dialog, enter a name for the file. For a synced configuration file, select the checkbox, specify your team and app in the drop-down menus that appear, then click Next. For a local configuration, leave the checkbox unselected, then click Next.

5. Select a location, and click Create.

6. Save the file to your project.

Create Products

Must inherit String AND VaultProductIterable for now, as the raw Representable just checks for such. Will make more generic.

import VaultKit

struct VaultProducts {
    enum Renewable: String, VaultProductIterable {
        case monthly = "...product_id..."
        
        var kind: VaultProductKind {
            .renewable
        }
    }
    
    enum NonRenewable: String, VaultProductIterable {
        case month = "...product_id..."
        case week = "...product_id..."
        case day = "...product_id..."
        
        var kind: VaultProductKind {
            .nonRenewable
        }
    }
}

Load VaultManager

var manager = VaultManager
                        .load(
                            VaultProducts.Renewable.vaultProducts +
                            VaultProducts.NonRenewable.vaultProducts
                        )

Purchase Product

manager.purchase(VaultProducts.Renewable.monthly)

Restore Purchases

manager.restorePurchases()

Check Purchase

manager.isPurchased(VaultProducts.Renewable.monthly)

Retrieve Metadata

public struct Metadata {
    let displayName: String
    let displayPrice: String
    let isRenewable: Bool
    let isPurchased: Bool
}

manager.metadata(VaultProducts.Renewable.monthly)

//Statically available
VaultManager.metadata(VaultProducts.Renewable.monthly)

Helpers

//VaultManager.swift

public var isSubscribed: Bool { get }

public var products: [VaultProduct] { get }

public var renewableProducts: [VaultProduct] { get }

public var nonRenewableProducts: [VaultProduct] { get }

//Preserves ordering of the enum that stores your products
manager.products.ordered 

//Returns the collection as Metadata objects, best for UI display cases
//Identifiable and Codable
manager.products.ordered.asMetadata
manager.products.asMetadata
