有一个GitHub项目叫做Xcode project Renamer:

它应该在Xcode项目目录的根目录中执行，并使用两个字符串参数调用:$OLD_PROJECT_NAME和$NEW_PROJECT_NAME 脚本递归遍历所有文件和目录， 包括Xcode项目或工作空间文件，并替换所有发生的事件 $OLD_PROJECT_NAME字符串和$NEW_PROJECT_NAME字符串(两者都在 每个文件的名称和内容)。

别忘了备份你的项目!

除了Luke和Vaiden推荐的所有步骤之外，我还必须重命名Storyboard中的所有customModule属性以匹配新名称，并且这必须区分大小写。

One more thing to note that I don't think has been noted yet is if you are using CoreData objects along with a lazy persistentContainer in the AppDelegate file (or anywhere else), you may get an error saying NSManagedObjectContext is nil (or something along those lines). Change the name for any NSPersistentContainer to use the NEW app name. That should fix the issue! If not, according to this old SO post the solution is to delete your old .xcdatamodeld file and create a new one adding back all the entities again.

现在真的很简单了。只需转到Project Navigator，即Xcode窗口的左侧面板。 按Enter键使其激活以进行重命名，就像更改文件夹名称一样。

只需要在这里更改新名称，Xcode会要求你重命名其他东西。

点击这里的重命名，你就完成了。

如果你对根文件夹的名称感到困惑，比如为什么它没有改变，那么它只是一个文件夹。它只是用一个新名字重新命名它。

我在网上找到了一些有用的简单步骤:
