When I import my project from Github, I have two folders that appear in Xcode with a blue color, but all other folders are yellow. What's happening?
Blue is used to represent the Folder Directory.
A clear description of what they are and when to use them comes from http://struct.ca/2010/xcode-folder-references/
There are two types of folders in Xcode: groups and folder links. You can use groups to organize files in your project without affecting their structure in the real file system. This is great for code because you are only going to work with your code in Xcode. On the other hand, arent groups are very good for resource files.In any fairly complex project, you usually deal with dozens - if not hundreds - of asset files, and these assets will need to be modified and manipulated outside of Xcode, either by you or by your designer. Putting all your resource files in one flat folder is the path to disaster. Here you will find links to folders. allow you to organize files into folders on your file system and keep the same folder structure in Xcode.
