If you are adding a new group named Organizer inside the default classes group you cant see the physical folder in finder. To make physical folder you should do following steps,
1. Prepare folder structure with files in it. 2. Drag that folder into xcode i.e. project navigation pan. 3. Check the box " Copy items into destination group's folder (if needed) " 4. Select " Create groups for any added folders "
After doing this, you will get your folder in finder. Now if you want to add new file then just
1. Right click on folder and click " Add files to < Project_Name >" 2. Select proper file 3. Check the box " Copy items into destination group's folder (if needed) " 4. Select " Create groups for any added folders " 5. Finally click to add
You will get that folder with new file added into that.
Note : Keep in mind you get yellow colored folder.
Thank You.
