How to add new class file to group in Xcode?
提问by dcgoss
I have noticed that now whenever I do command-N to create a new Cocoa Touch class in my project, it keeps adding the file outside of the project in the file tree:
我注意到现在每当我执行 command-N 在我的项目中创建一个新的 Cocoa Touch 类时，它都会在文件树中的项目外部添加文件：
The behavior I remember (I haven't touched this project in a few weeks), is that whenever I create a new class it automatically places it in the group that you are currently working in, something like this:
我记得的行为（我已经几周没有接触过这个项目了）是，每当我创建一个新类时，它都会自动将它放在您当前工作的组中，如下所示：
Is there any way to restore this behavior? Creating a new plain .swift file seems to give you the choice of picking the group, but creating a new Cocoa Touch class does not. Regardless, I don't remember having to pick the group at all, it "just worked".
有什么办法可以恢复这种行为吗？创建一个新的普通 .swift 文件似乎可以让您选择组，但创建一个新的 Cocoa Touch 类则不然。无论如何，我根本不记得必须选择该组，它“只是有效”。
Please let me know if you need any more info. Xcode v6.3.2/6.4 on El Capitan
如果您需要更多信息，请告诉我。El Capitan 上的 Xcode v6.3.2/6.4
EDIT: I have tested further, and it seems the correct behavior is observed when adding new swift files and playgrounds, but not when adding new Cocoa Touch Classes.
编辑：我进行了进一步测试，似乎在添加新的 swift 文件和 Playground 时观察到了正确的行为，但在添加新的 Cocoa Touch 类时却没有观察到。
EDIT 2: Here is photos of the file creation process and how it isn't working:
编辑 2：这是文件创建过程的照片以及它是如何工作的：
Step 1) Command-N, select new Cocoa Touch Class
步骤 1) Command-N，选择新的 Cocoa Touch Class
Step 2) Name class like usual:
步骤 2) 像往常一样命名类：
Step 3) Here is where the problem seems to lie. It gives me the option of placing where I want my files to be saved to on the disk, but it isn't allowing me to choose a group or target:
第 3 步）这就是问题所在。它让我可以选择将文件保存在磁盘上的位置，但它不允许我选择组或目标：
I also discovered that clicking the Optionsbutton on the bottom seems to bring up the group and target selection pane, but they are grayed out and cannot be interacted with:
我还发现单击Options底部的按钮似乎会调出组和目标选择窗格，但它们是灰色的，无法与之交互：
EDIT 3: Just tested same action with Xcode 7 and Xcode 7 gets it right. Seems to be some kind of bug with Xcode 6.3.2/6.4
编辑 3：刚刚用 Xcode 7 测试了相同的操作，Xcode 7 就正确了。似乎是 Xcode 6.3.2/6.4 的某种错误

I had the same problem in Xcode 6.4. Just create a new Cocoa Touch class in your project and after that, delete the reference to this file(delete->Remove Reference). After that go to File->Add File to your project, find your file in project folder. There you will be able to selecte target project in select the Group. I think it will help you :)
我在 Xcode 6.4 中遇到了同样的问题。只需在您的项目中创建一个新的 Cocoa Touch 类，然后删除对此文件的引用(delete->Remove Reference)。之后转到文件->将文件添加到您的项目，在项目文件夹中找到您的文件。在那里您将能够在选择组中选择目标项目。我认为它会帮助你:)
