关于That command depends on command in Target ... script phase Copy Pods Resources报错解决方案

最近在最新的Xcode11.5中编译从Github上下载的老项目，出现一个bug，提示如下：

Multiple commands produce '/xxx.app':

2) That command depends on command in Target 'xxx': script phase “[CP] Copy Pods Resources”

出现该问题是因为自Xcode10之后默认使用的build system是New build system，我们只要将build system设置成legacy build system就好了。

操作如下图：
