Adding files in Xcode 4.2 does not work (blue folders, files are not recognized)

Question

In Xcode 4.2, every time I try to add file folders to my project, the files are not recognized. Typically, a folder is added and displayed as a yellow folder in Xcode. But now, every time I add files to my project, my folders are blue and they are incorrectly recognized by Xcode.

Answer 1

I encounter the same situation after upgrading Xcode to 4.2. My solution drags the entire folder into the Xcode project, after which a dialog box appears in which you learn how to handle it. Select Create Groups for Any Added Folders and click Finish. Then it should work and show the “yellow” folder of the group instead of blue. Hurrah!

Answer 2

When adding a new file to an open panel using the create groups or create folders radio button, a radio button for any added folder appears. Make sure crate groups selected.

Answer 3

A screenshot shows that the folder has crashed; did you click the little triangle next to it to see the contents of the folder?

Answer 4

Click the project name and press cmd-N

Step 1 - Select a template for your file Step 2 - Enter the class name Step 3 - you will be asked to select the group in which you want to create a class

After creating the class files, select the class files, right-click and select (New group with name)
