Declaration

static var shared: VerificationResult<AppTransaction> { get async throws }

Discussion

Use this property to get a VerificationResult that contains the App Store-signed app transaction information for your app, including the first time the app launches. StoreKit automatically keeps the app transaction up-to-date.

This property throws an error if the AppTransaction isn’t available or if the user isn’t authenticated with the App Store. Getting an AppTransaction may require network connectivity.

The following example shows how to get the AppTransaction.

do {
    let verificationResult = try await AppTransaction.shared

    switch verificationResult {
    case .verified(let appTransaction):
        // StoreKit verified that the user purchased this app and
        // the properties in the AppTransaction instance.
        // Add your code here.
    case .unverified(let appTransaction, let verificationError):
        // The app transaction didn't pass StoreKit's verification.        
        // Handle unverified app transaction information according
        // to your business model.
        // Add your code here.
    }
}
catch {
  // Handle errors.
}

If your app fails to get an AppTransaction by accessing the shared property, see refresh().
