xcode上传appstore报 “Missing Provisioning Profile - Apps must contain a provisioning profile in a file“

XCode上传AppStore时，老是报以下错错误的解决办法：

ERROR ITMS-90174: “Missing Provisioning Profile - Apps must contain a provisioning profile in a file named embedded.mobileprovision.”

然后试了好几种方式都不行，最后找到了一个帖子是这么说的：

 

 打开XCode点击"File" > "Project Settings..."

选择"Legacy Build System"
