贝宝 - 本地结帐SDK（ios） - 无效范围

Question

我正在关注本地结帐sdk https://developer.paypeveloper.paypal.com/limited.com/limited.com/limited -Release/native-Checkout/ios/使用与文档相同的代码

configuartion client ID并返回给定的URL

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
        FirebaseApp.configure()
        let config = CheckoutConfig(
                clientID: "XXX",
                returnUrl: "xyz",
                environment: .sandbox
            )
            Checkout.set(config: config)
        return true
    }

    func configurePayPalCheckout() {
           print("__________________________________________________________________________________________________")
           Checkout.setCreateOrderCallback { createOrderAction in
               let amount = PurchaseUnit.Amount(currencyCode: .usd, value: "10.00")
               let purchaseUnit = PurchaseUnit(amount: amount)
               let order = OrderRequest(intent: .capture, purchaseUnits: [purchaseUnit])

               createOrderAction.create(order: order)
           }

           Checkout.setOnApproveCallback { approval in
                approval.actions.capture { (response, error) in
                   print("Order successfully captured: \(response?.data)")
                    print("error ::::::::::::::::::::::::::::::::::::::::::::::",error)
               }
           }
            Checkout.setOnCancelCallback {
                // User has cancelled the payment experience
                print("cancel")
            }
            Checkout.setOnErrorCallback { error in
                // Handle the error generated by the SDK
                print("error" , error)
            }
    }
