Creating Folder Reference
As opposed to groups in AppCode, the folder reference is a physical structure. The folder references allow you to organize your files into folders on your file system keeping that same folder structure in AppCode. Therefore, you can manage your asset files from outside of the IDE.
To create a new folder reference
In the Project tool window, select the desired group.
In the New Folder Reference dialog box that opens, specify the folder name. You can also change the group and target here, when required.
Click OK to create the folder reference and respective physical folder.
