Objective c 如何将现有Swift模块与视图连接到React Native？

我已经让模块使用Bridge，但我不知道如何调用React本机内部的SWIFT视图

我得到了这个错误：其视图不在窗口层次结构中！在XCODE日志中

import MercadoPagoSDK
import UIKit


@objc(MercadoPago)
class MercadoPago: UIView {
  @objc  func getPayment(_ publicKey : NSString,preferenceId : NSString,callback: RCTResponseSenderBlock) -> Void {
      //callback([count])

    let checkout = MercadoPagoCheckout.init(builder: MercadoPagoCheckoutBuilder.init(publicKey: publicKey as String, preferenceId: preferenceId as String))

    checkout.start(navigationController: UIViewController)

  }
}

使用React Native 0.61.2

正在尝试移植模块MercadoPagoSDK：

尝试桥接模块，但UI视图未出现，XCODE日志中出现错误；其视图不在窗口层次结构中！在XCODE日志中

import MercadoPagoSDK
import UIKit


@objc(MercadoPago)
class MercadoPago: UIView {
  @objc  func getPayment(_ publicKey : NSString,preferenceId : NSString,callback: RCTResponseSenderBlock) -> Void {
      //callback([count])

    let checkout = MercadoPagoCheckout.init(builder: MercadoPagoCheckoutBuilder.init(publicKey: publicKey as String, preferenceId: preferenceId as String))

    checkout.start(navigationController: UIViewController)

  }
}

我需要将返回的视图显示到react native view controller中
