I am used to Visual studio, I have class library projects that I reference in my web sites or windows applications. Using class libraries allows me to create common functionalities, utilities once and use them over and over again.
How do I do this with Xcode and iPhone App development?
I am looking for some details on how to create the library, where to stores the files and how to reference in my App. That is if it is possible.
I am very very new to Mac and Xcode.
