    Over here, we shall be using XCode7 Interface for our pedagogy.

XCode Interface

The diagram shown above refers you the different sections of the interface namely Navigator, Editor, Debug Area and Utility Area. The size of these panels can be changed by hovering the cursor over the boundaries of each area and dragging.
You can also display and hide the various areas as required by using “View” buttons in the upper right-hand corner.
Protecting the debugger area or utility area can be useful when you are writing code so that you can have more editor space.

  • Navigator Area
    In this pane, there are three navigators such as Project, Search, and Issue navigators that are used to switch between using the Navigator Selector Bar.
  • Project Navigator
    It displays all the files associated with your project.

Project Navigator

  •  You can create “Groups” to organize your files in using project navigator.
  • Right-click and select Create Group for creating agroup. It doesn’t create a folder in the file system wherein it exists in your Xcode project.
  •  Create actual directories on your hard drive, organize the files, and drag them into the Xcode project.
  •  Right-click on the project navigator and create new files or add existing files to your project. Or you can directly drag folders or files from your system, and a popup dialog box shall ask you if you want to add the libraries.
  •  If you click on a file in the project navigator, you can see the file content displayed in the editor area. If you double-click the file, a new window pop-up which can be useful when you have two monitors.
  •  If you click the root node of the project navigator, the project properties will be open in the editor area.

Project Navigator

  • Search Navigator

You can search pieces of text in your project by using search navigator tab.
Search Navigator

You can use search pilot when you are looking for particular property, method, or variable which are difficult to remember.

  • Issue Navigator

Issue Navigator will notify all the problems in your app.

Issue Navigator

After you build and compile your application, the Xcode cannot make your app and halt it if there are any issues in your app. You can click on an error marked in red color, and it will show you the file and line it’s failing at in the editor area.

  • Editor Area
    You will be probably spending more time in this area where all coding happens.

Editor Area

Navigation within the editor area

Back and Forward arrows contained in the upper left corner of the editor area are similar to the back and forward buttons on your browser, and they help you to navigate to previously viewed files.

Another way of navigation is by using Jump Bar as depicted in the figure below. The jump bar allows you to drill quickly down through the required groups and files. When you click on it, it will open a menu with other groups in hierarchy level.

If you click the tail portion of the jump bar, a menu will show you all the methods you can implement within the file which are not useful to jump to another area within the archive. But it will show you at a glimpse the methods available in the file.

  • Utility Area
    The Xcodeservice area comprises two panes namely inspector pane and library pane.
    Utility Area

The Inspector pane will give you the details about the files which are highlighted in your project navigator.
You can drag UI elements from the library pane onto editor area to add that element to your UI.

  • Debug Area
    This area shows you the console output and state of various variables when you run your application.

Debug Area

  • Xcode Organizer
    Click on the menu entry Window->Organizer to open the Xcode Organizer.

  • Devices
    Your provisioning profiles can be managed on your system and various devices. This option is necessary for deploying your app on actual physical iOS devices.
  • IOS Simulator
    Xcode provides you an incredible iOS simulator for you to test your application. You can use this tool for most of your development and then find a device to test.

Kudos!! The app is ready to roll now.
