Apple pay not working in iPhone 6s Simulator for ionic 4

#1

I am trying to create Apple-pay from https://ionicframework.com/docs/native/apple-pay/

the following two error I found :

  1. completeTransactionWithMerchant not found .

please let me know how can I solve?

  1. when I removed following lines from above URL doc it’s working and create a build in iPhone 6s simulator
    removed code :
const transactionStatus = await completeTransactionWithMerchant(applePayTransaction);
    await this.applePay.completeLastTransaction(transactionStatus);

Added code : console.log(applePayTransaction) ; //for debug

but during runtime

I got following error:-
