GOOStore

Store Manager for SwiftUI and In-App Purchases

💶 About GOOStore

GOOStore is a Library prepared to use In-App Purchases in iOS and macOS developments with SwiftUI

⚙️ Installation

Setup your XCode Project and App Store Connect

First of all you need to add In-App Purchases capabilities in your app

In Xcode select your Target and change to the Signing & Capabilites tab.
Add In-App Purchase capability.

Add your In-App Purchases in App Store Connect

Consumable purchases - for example dev.goojoob.MyApp.10lives and dev.goojoob.MyApp.50lives
Non-Consumable - for example dev.goojoob.MyApp.ProUser

Setup with Swift Package Manager

In Xcode select File > Add Packages.
Enter this project's URL: https://github.com/goojoob/GOOStore.git

🔧 Usage

Declare your available products id's and quantity as a Dictionary.

Consumable items need a quantity you may treat when the purchase is done
Non-Consumable items don't need a quantity, so you may use a number to identify it

let myProducts: [String: Int] = ["dev.goojoob.MyApp.10lives": 10, "dev.goojoob.MyApp.50lives": 50, "dev.goojoob.MyApp.ProUser": 999]

Create a StateObject var in your View with your products:

import GOOStore

//...

@StateObject private var storeManager: GOOStore = GOOStore(products: myProducts)

Show your products in a View (this design is up to you):

ForEach(storeManager
    .myProducts
    .sorted(by: { $0.price.floatValue < $1.price.floatValue }), id: \.self) { product in
        HStack {
            VStack(alignment: .leading) {
                Text(product.localizedTitle)
                Text(product.localizedDescription)
            }

            Spacer()

            Button {
                storeManager.purchaseProduct(product: product)
            } label: {
                HStack {
                    Text("\(product.localizedPrice ?? "00")")
                    Image(systemName: "creditcard")
                }
            }
        }
    }

Let Restore Purchases available (for example in the toolbar):

.toolbar {
    ToolbarItem(placement: .navigationBarTrailing) {
        Button {
            storeManager.restoreProducts()
        } label: {
            Text("Restore Purchases")
        }
    }
}

Process the purchase/restore in a View:

Variable lastBuy is a tuple containing the las item purchased, its productId and quantity

.onChange(of: storeManager.transactionState) { transactionState in
    switch transactionState {
    case .purchased:
        print("StoreManager - Purchased: '\(storeManager.lastBuy.productId)' Quantity: \(storeManager.lastBuy.quantity)")
        //treat your purchase
    case .restored:
        //treat your restored purchases
    default:
        break
    }
}
