在Xcode 12中使用Non-Exempt Encryption而不是ITSAppUsesNonExemptEncryption

要从下拉菜单中选择，请输入以下一行:

应用程序使用非豁免加密

苹果简化了我们的构建过程，所以你不需要每次都点击相同的复选框。你可以通过将这个标志编译到应用程序中来简化你的iTC流程。

截至2019年，情况仍然如此。

同样的错误是这样解决的

在Xcode 12中使用Non-Exempt Encryption而不是ITSAppUsesNonExemptEncryption

在plist文件中添加此密钥…一切都会好起来的。

<key>ITSAppUsesNonExemptEncryption</key>  
<false/>

只是在</dict></plist>之前粘贴
