I solved the problem by referring to @nicolaischneider answer in UIKit. Present the view controller like this: guard let scene = UIApplication.shared.windows.first?.windowScene else { return } let viewController = UIViewController() let window = UIWindow(windowScene: scene) window.isHidden = true window.windowLevel = .normal - 1 window.rootViewController = viewController window.makeKeyAndVisible() DispatchQueue.main.async { self.present(viewController, animated: true) } Use purchase(confirmIn:) function: let result = if #available(iOS 17.0, *), let scene = await UIApplication.shared.windows.first?.windowScene { try await product.purchase(confirmIn: scene) } else { try await product.purchase() }
