Program: Anything that is executable on a computer we call a program.
Application: Some programs have graphical user interface, we call these Applications.
Daemons: Some programs have no graphical user interface and run for days in the background, we call these Daemons.
Command Line Tools: Some programs have no graphical user interface and run for a short time in the terminal, we call these Command Line Tools.
Code Completion: As you type, Xcode tries to make helpful suggestion. This features is called code completion.
Note1: Remember that Xcode builds your program & then tuns it. For building your program use Command + B and for running your program use Command + R keys.
Note2: The navigator area is so important because you need it for adding files, see your log, etc. We have 7 kind of navigator, for instance one of them is Log Navigator.
Log Navigator: The Log Navigator is Xcode’s way of communicating with you when it is building and running your program.
