5. RevenueCat for In-App Purchases
RevenueCat simplifies in-app purchases and subscriptions, making it easier to manage payments across platforms. It’s a powerful tool that handles all the complexities of in-app purchases with just a few lines of code.
Integrating RevenueCat
First, add RevenueCat to your project via Swift Package Manager:
swift
dependencies: [ .package(url: "https://github.com/RevenueCat/purchases-ios", .upToNextMajor(from: "4.0.0")) ]
Then, initialize the SDK in your App file:
swift
import Purchases @main struct MyApp: App { init() { Purchases.configure(withAPIKey: "your-revenuecat-api-key") } var body: some Scene { WindowGroup { ContentView() } } }
To display available products and allow users to make purchases:
swift
import SwiftUI import Purchases struct ContentView: View { @State private var offerings: Offerings? var body: some View { VStack { if let offering = offerings?.current { ForEach(offering.availablePackages) { package in Button(action: { Purchases.shared.purchase(package: package) { transaction, purchaserInfo, error, userCancelled in // Handle the result of the purchase } }) { Text(package.product.localizedTitle) } } } } .onAppear { Purchases.shared.getOfferings { (offerings, error) in self.offerings = offerings } } } }
This allows you to offer in-app purchases or subscriptions within your app seamlessly.
