我正在使用RMAppReceipt来验证我的应用程序中的应用程序购买，在更新到XCode 9之前，这一切都运行良好。我已经按照www.example.com页面的指示将RMAppReceipt. h、RMAppReceipt.m、RMAppStoreReceiptVerifier. h和RMAppStoreReceiptVerifier.m文件添加到我的项目中https://github.com/robotmedia/RMStore/wiki/Receipt-verification#adding-openssl，并添加了“OpenSSL-通用”pod。
这在XCode 8.3中运行良好，但在ProjectNameUITests文件夹中将代码更新为Swift 4.0后，出现了以下错误：
Apple Mach-O链接器（Id）错误：
