SwiftBindings.Apple.StoreKit2 26.2.10

SwiftBindings.Apple.StoreKit2

Native .NET bindings for Apple's StoreKit 2 — the Swift-first In-App Purchase API on top of StoreKit. These are not Objective-C proxy wrappers; they use .NET 10's native Swift interop for direct, high-performance calls into Swift APIs from C#.

Installation

dotnet add package SwiftBindings.Apple.StoreKit2

Requirements

• .NET 10.0+
• Target framework: net10.0-ios26.2 (or -macos26.2 / -maccatalyst26.2 / -tvos26.2) or higher. The package is compiled against the iOS 26.2 SDK supplement, so your app's <TargetFramework> platform version must be ≥ 26.2 to restore it — an explicit lower TPV (e.g. net10.0-ios18.0) or a bare net10.0-ios whose installed workload defaults below 26.2 fails restore with NU1202. This is the compile-SDK pin, not your app's deployment minimum.
• Deployment minimum is separate — set your app's real minimum OS with <SupportedOSPlatformVersion> (independent of the TFM above). Individual APIs that need a newer OS at runtime are gated by generated [SupportedOSPlatform] attributes; the C# compiler flags a call that isn't valid for your target.
• macOS host for development
• App Store Connect-configured products for live purchase flows; a StoreKit configuration file works for local testing

Usage

Capability checks

using StoreKit2;

bool canBuy = AppStore.CanMakePayments;
Guid? deviceVerifyId = AppStore.DeviceVerificationID;

Async transaction sequences

var allTransactions = Transaction.All;
var entitlements = Transaction.CurrentEntitlements;
var unfinished = Transaction.Unfinished;
var updates = Transaction.Updates;

Verifying a transaction payload

// VerificationResult<T> projects to TryGet-style C# methods.
// (You'll get a real instance from any of the async sequences above.)
if (result.TryGetVerified(out Transaction tx))
{
    // tx is the verified payload
}
else if (result.TryGetUnverified(out Transaction unverifiedTx, out var error))
{
    // unverifiedTx + the verification error are exposed
}

Errors

var description = Product.PurchaseError.InvalidQuantity.GetErrorDescription();
var refundDesc = Transaction.RefundRequestError.DuplicateRequest.GetErrorDescription();
