Apple Pay-swift篇

摘要: 针对swift写一篇Apple Pay

这是上一篇的OC版 有一些文字说明，Merchant ID 证书配置 可以参照

补充一点证书方面的东西

签发机构在钥匙串中是以Apple Worldwide Developer Relations开头的证书
Apple Worldwide Developer Relations Certification Authority(简称AppleWWDRCA)基本上普通的开发证书都是AppleWWDRCA签发者
用到Apple pay可能会接触到Apple Worldwide Developer Relations CA - G2(简称AppleWWDRCAG2)

Apple Pay 证书无效 提示未知颁发机构签名
下载证书进行安装

如图：

代码说明如下:
