Deciphering the Xcode Interface
You can check the full Apple documentation for Xcode in different links. First thing you need to make sure is that you are using the latest version of the Xcode 8. The Xcode application must be opened then. In the application you can spot 4 major areas such as the Editor, Navigator, Debugging area and Utility Area. You can adjust the size of each of the panes by just drifting your cursor over the boundaries of each dragging and area. You can manipulate the various area’s visibility with the help of upper right hand corner button. This feature can be helpful as for example, when you are writing a code and you do not require the Debugger and the utility area at that moment, you can use the view buttons to hide those 2 panes to receive more visible area for your work.
In the Navigator pane, there are a bunch of various navigators that can help you to switch between using the Navigator selector bar. The there are three navigators that you will use a lot, which are Project, issue and Search navigator.
Project Navigator: The project Navigator is the place where you will see all the files which are related to your project. Within that navigator, you can create groups for organizing your files. The navigator actually does not create a folder in the file system; it will only exist in your Xcode project. This will not exactly organize your actual files in your hard drive. The root node of the project navigator is your Xcode project file which will be indicated in blue icon.
Search Navigator: With the help of the search navigator tab, you can easily search and look for different pieces of the text in your project. You will find yourself using the search navigator a lot when you are looking for a specific property, variable or method and you cannot remember where exactly it is.
Issue Navigator: The issue navigator is an important feature of the Xcode. This navigator helps you to show all the problems associated with your application. After building and compiling your application you test it, if there are any problems where Xcode is not capable of resolving, it will stop and show the problem in red colored errors.
The most spent time by a developer is in this Editor Area. This is where all the coding is performed. In the project navigator section, when you select a file there, it will open the contents in the editor area. You can perform the edits required for your contents.
Little back and forward arrows are present in the upper left corner of the Editor Area. These arrows aren’t labeled in the Xcode interface diagram at the beginning. These arrows are pretty useful, as they act like the back and forward buttons on your browser. These arrows help you to navigate to previously visited files. Another way to quickly navigate to the previously viewed files is to use Jump Bar. The Jump bar allows you to drill down through your created groups and find the files you require.

The Xcode utility area consists of two panes – The library pane and the inspector pane. The Inspector pane will provide you the details about the file you have highlighted during coding. This pane would show you the different attributes that you can select and modify. The Library pane will not be that useful if you are looking at a XIB/ Story Board file. While using the Interface Builder part of the Xcode, you can select and drag the UI elements from the library pane to the editor area. The dragging will add that element to your interface.
The debugging area will help you to view the console output and the state of various variables when you run your developed application. You will be using this Debug area a lot while debugging your created code. If you are trying to figure out why things aren’t working out the way you had created, then an explained way of Xcode debugging tutorial you can get in some websites.
We have already discussed about some of the panes and buttons on the toolbar. The left most button is the run button. This will help you to build and run you app. This run button will also help you to launch your created application in the iOS Simulator. The button next to the run button would stop the execution of your app and redirect you to the Xcode. If you click and hold down the Run button, you can explore more options to run your application such as Test, Analyze and Profile.
The latest version of the Xcode 8 is bundled with an awesome iOS simulator for helping you to test your application on. iOS simulator can be used for most of your application development and then find a device for testing when you have almost finished. The iOS Simulation can actually do a lot which includes:
