As mentioned in the project navigator section, when you click a file there, it will open the contents in this editor area for you to edit the contents. Navigation within the editor area There are these little back and forward arrows in the upper left corner of the editor area.
They act like the back and forward buttons on your browser and they let you navigate to previously viewed files.

Another way to quickly get to the file you need is to use the Jump Bar see diagram. The jump bar allows you to quickly drill down through your groups and find the file you need.
That does it for navigation within the editor area however, it still has some tricks up its sleeve. It looks like a two pane view. Each pane also has independent jump bars, so you can also use that to change what file each pane is displaying.
The right most button is the Version Editor view where you can compare two files. Finding and replacing within the file Just hit Command-F to bring up a search popup in the upper right corner that will look for whatever you type in within the current file. This is also a great way to jump to various areas of your file.
You can also use this popup to do replacements within your file. The breakpoint gutter The breakpoint gutter see diagram at top is where you can click to set breakpoints at certain lines of code.
To turn off a breakpoint, just click the blue indicator again and it will dim out. If you want to completely remove the breakpoint, you can click and drag the blue indicator off of the breakpoint gutter. The Library Pane For developers who started iOS with Xcode 9 and earlier, the library pane used to be right bellow the inspector pane. The Debug Area The debug area will show you console output and the state of various variables when you run your application.
The left-most button is the run button. Plus, you will get the full source of two extra apps we are currently building. The other is a subscription app that keeps track of your subscription spending.
You're given the right to modify the source code and use them in your own projects.
What people say about us "This book got me an internship and a job. Best money I ever spent!! To me, and a lot of developers, your talent, knowledge, expertise and willingness to share have been simply a godsend. I bought this book and played with the code.
I am now absorbing what I learned and am in the process of creating an app that I will put on the app store. This was my breakthrough. Just awesome.
Your books saved my life. They're the best explained programming books I've ever read in my 10 years of programming. They're so easy to understand and they hit everything. I will never thank you enough for writing the books and I owe you a lot. I am an experienced developer in another language and this book was exactly what was needed. It showed the idea behind iOS user interface and step by step it was taking you deeper.
I strongly advice it for developer who have some background with developing in another environment and wants to learn swift. The flow, the videos, the content, everything just makes it damn easy to learn and get started with iOS programming.
Also, really appreciate the updates you keep doing, this is more of a living book rather a hard printed book frozen in time.

Just awesome - you are giving an opportunity to several wannabes who would not have been! Keep going and all the best! But my biggest and most steady progress has been using this course material. I'm not sure why it's clicking now more than before, but the way the course is structured just makes sense to me. And what I really love is it's project based learning approach.
You actually make things as you learn, and by doing so you start to get those "ah ha" moments. There's nothing more exciting than figuring something out that at first you just couldn't get your head around. As a high school AP computer science teacher I work mainly with Java but I also teach several other programming languages so I tend to keep a large library of books on-hand. While many of the other books and online video tutorials I purchased these past years were very good, I found AppCoda's to be far above all others.
Simon has a way of presenting a topic in such a manner where I felt he was teaching me in a classroom environment rather than just me reading words on a screen. We will then send you a sample book with page of free content. Starting by creating an app prototype, we will add one feature at a time and you will have a real app after going through the course.
Understand Safe Area in iOS Right now you want to insert UI elements, so select the Object library which is the third from the left. Finally, add a Label. Now, build and run the app using the Play button or Command-R.
You will see these 3 UI elements.
Try typing in the text field — it already supports all the standard editing shortcuts: copy, paste, cut, select all, undo, redo and so on. Configuring the UI Go back to Main. In the Utilities panel on the right, make sure the Attributes Inspector is showing — the 4th button across the top.

The button may not be wide enough to show all the text, so go to the Editor menu and select Size to Fit Content which should fix that. If Size to Fit Content is disabled, click somewhere to de-select the button, then re-select it and try again.
Now click in the text field to select it. To help the users, add some placeholder text to the text field using the Attributes Inspector. Stretch the text field out a bit to allow for long names and position the button to the right of it. Position the label below the text field and button. Since the label is going to be important, make it use a larger font.
Select the label and in the Attributes Inspector, change the font to System Regular How about making the text red to add even more excitement? With the Main. This will create a second editor panel containing the ViewController code. Depending on the size of your monitor, things may be looking a bit cramped now, so use the rightmost button in the Toolbar to hide the Utilities.
If you need even more space, hide the Navigator. Select the text field. Hold down the Control key and drag from the text field into the top of the ViewController class definition.
Let go and enter nameField in the name box of the popup, then click Connect. Do the same with the label, naming it helloLabel. Looking at the code that Xcode has generated, you see that these are both marked with IBOutlet.
This is short for Interface Builder Outlet and is how you tell the storyboard editor that these object names are available for linking to a visual object. For the button, the code does not need to have a name for it, but it does need to know when a user clicks the button.
Select the button and Control-Drag into ViewController. This time, change the Connection popup to Action and set the name to sayButtonClicked.

This creates the function that will be called when the button is clicked. Everything is now in place to edit the code. If you had hidden the Navigator, click the toggle button in the top right, or press Command-1 to jump directly to the Project Navigator. Enter the following code into sayButtonClicked. The blobs beside the line numbers indicate a connection to the interface in the storyboard.
Build and run the app. Now type in your name and click the button again to see your own personal greeting. Debugging Sometimes, we programmers make mistakes — hard to believe I know, but trust me, it happens.
And when it does, we need to be able to debug our code. Xcode allows us to stop the code at any point and step through line by line, checking the values of the variables at each point so that we can find the error.
Go to sayButtonClicked in ViewController. A blue pointed rectangle will appear. This is an active breakpoint and when you click the button, the debugger will stop here.
Click it again and it will turn pale blue.Finally, add a Label. Now type in your name and click the button again to see your own personal greeting. The book and the sample apps are fully updated to support Xcode 10, Swift 5 and iOS Click it again and it will turn pale blue. Let us look at some of the good tutorials to get you started with Xcode, we will also cover some tutorials that provide step by step instructions to create fully functional iPhone and iPad apps using Xcode 8, Swift 3 and iOS
