O autorze

Alex Nekrasov wrote his first line of code 27 years ago when he was 8 years old and could see himself thriving as a software developer ever since. In 2008, he graduated from university with a diploma with honors as a System Engineer. By that point, he had already been working in the IT field for 3 years. In 2013, he wrote his first iOS app and, in 2014, he switched completely to mobile development. Almost 10 years of freelance experience has given Alex an opportunity to work on many interesting projects and earn real-life experience. Alex runs a succesful blog where he writes about mobile development.

Boost your iOS developer career by learning from real-life examples and start writing code for one of the most successful platforms ever. No matter if you’re an experienced developer or just a beginner, you’ll find something new and something useful for your future projects here.    

All of the recipes in this book are taken from real-life commercial projects that have been approved by Apple and published on the App Store. You won’t write “Hello, world!” and similar programs. Instead you'll see how to parse different data formats; run JavaScript code right inside your iOS app; and enhance storyboard editor with several simple extensions. You’ll make beautiful modern-looking dialogs with blurs, shadows and rounded corners using only a few lines of code, and safely convert data after analyzing text strings. Go on to animate your layout and get your app shored up to crash as little as possible    

Each recipe offers a code snippet to copy and paste to your project as a tool to boost your knowledge, as well as, create plug-and-play features. Each of recipe shows the description for each line of code while explaining the logic of it, contains references to documentation, and gives you an opportunity to modify or write something similar that fits your project better.    

A good piece of code should not work but also be short, clear, and stable. And that combo will be our priority in these code recipes. Well-written code snippets must run in any environment and be easily transferrable from one project to another. Most of the provided recipes will migrate from one project to another with little to no changes at all, and with years of real-world application have proven themselves to be useful and stable. Dive into the world of iOS development and write clear, functioning, and safe Swift code!  

You will:

• Parse, convert, and print Swift data   
  
• Develop stunning UIs quickly  
  
• Write effective and portable Swift extensions  
  
• Make your code cleaner and safer
