Swift: Developing iOS Applications. Developing iOS Applications

Jon Hoffman, Andrew J Wagner, Giordano Scalzo

The Swift––Developing iOS Applications course will take you on a journey to become an efficient iOS and OS X developer, with the latest trending topic in town. Right from the basics to the advanced level topics, this course would cover everything in detail. We’ll embark our journey by dividing the learning path into four modules. Each of these modules are a mini course in their own right; and as you complete each one, you’ll gain key skills and be ready for the material in the next module.The first module is like a step-by-step guide to programming in Swift 2. Each topic is separated into compressible sections that are full of practical examples and easy-to-understand explanations. Each section builds on the previous topics, so you can develop a proficient and comprehensive understanding of app development in Swift 2. By the end of this module, you’ll have a basic understanding of Swift 2 and its functionalities.The second module will be the an easy-to-follow guide filled with tutorials to show you how to build real-world apps. The difficulty and complexity level increases chapter by chapter. Each chapter is dedicated to build a new app, beginning from a basic and unstyled app through to a full 3D game. The last two chapters show you how to build a complete client-server e-commerce app right from scratch. By the end of these modules, you’ll be able to build well-designed apps, effectively use AutoLayout, develop videogames, and build server apps.The third and the last module of our course will take an example-based approach where each concept covered is supported by example code to not only give you a good understanding of the concept, but also to demonstrate how to properly implement it.

Solidity Programming Essentials. A guide to building smart contracts and tokens using the widely used Solidity language - Second Edition

Ritesh Modi

Solidity is a high-level language for writing smart contracts, and the syntax has large similarities with JavaScript, thereby making it easier for developers to learn, design, compile, and deploy smart contracts on large blockchain ecosystems including Ethereum and Polygon among others. This book guides you in understanding Solidity programming from scratch.The book starts with step-by-step instructions for the installation of multiple tools and private blockchain, along with foundational concepts such as variables, data types, and programming constructs. You’ll then explore contracts based on an object-oriented paradigm, including the usage of constructors, interfaces, libraries, and abstract contracts. The following chapters help you get to grips with testing and debugging smart contracts. As you advance, you’ll learn about advanced concepts like assembly programming, advanced interfaces, usage of recovery, and error handling using try-catch blocks. You’ll also explore multiple design patterns for smart contracts alongside developing secure smart contracts, as well as gain a solid understanding of writing upgradable smart concepts and data modeling. Finally, you’ll discover how to create your own ERC20 and NFT tokens from scratch.By the end of this book, you will be able to write, deploy, and test smart contracts in Ethereum.

Python 3 Object Oriented Programming. If you feel it’s time you learned object-oriented programming techniques, this is the perfect book for you. Clearly written with practical exercises, it’s the painless way to learn how to harness the power of OOP in Python

Dusty Phillips

Object Oriented Programming is a very important aspect of modern programming languages. The basic principles of Object Oriented Programming are relatively easy to learn. Putting them together into working designs can be challenging.This book makes programming more of a pleasure than a chore using powerful Python 3 object-oriented features of Python 3. It clearly demonstrates the core OOP principles and how to correctly implement OOP in Python. Object Oriented Programming ranks high in importance among the many models Python supports. Yet, many programmers never bother learning the powerful features that make this language object oriented.The book teaches when and how OOP should be correctly applied. It emphasizes not only the simple syntax of OOP in Python, but also how to combine these objects into well-designed software.This book will introduce you to the terminology of the object-oriented paradigm, focusing on object-oriented design with step-by-step examples. It will take you from simple inheritance, one of the most useful tools in the object-oriented programmer's toolbox, all the way through to cooperative inheritance, one of the most complicated. You will be able to raise, handle, define, and manipulate exceptions.You will be able to integrate the object-oriented and the not-so-object-oriented aspects of Python. You will also be able to create maintainable applications by studying higher level design patterns. You'll learn the complexities of string and file manipulation, and how Python distinguishes between binary and textual data. Not one, but two very powerful automated testing systems will be introduced to you. You'll understand the joy of unit testing and just how easy they are to create. You'll even study higher level libraries such as database connectors and GUI toolkits and how they apply object-oriented principles.

Creating Dynamic UI with Android Fragments. Make your Android apps a superior, silky-smooth experience for the end-user with this comprehensive guide to creating a dynamic and multi-pane UI. Everything you need to know in one handy volume

Jim Wilson

To create a dynamic and multi-pane user interface on Android, you need to encapsulate UI components and activity behaviors into modules that you can swap into and out of your activities. You can create these modules with the fragment class, which behaves somewhat like a nested activity that can define its own layout and manage its own lifecycle. When a fragment specifies its own layout, it can be configured in different combinations with other fragments inside an activity to modify your layout configuration for different screen sizes (a small screen might show one fragment at a time, but a large screen can show two or more).Creating Dynamic UI with Android Fragments shows you how to create modern Android applications that meet the high expectations of today's users. You will learn how to incorporate rich navigation features like swipe-based screen browsing and how to create adaptive UIs that ensure your application looks fantastic whether run on a low cost smartphone or the latest tablet.This book looks at the impact fragments have on Android UI design and their role in both simplifying many common UI challenges and providing new ways to incorporate rich UI behaviors.You will learn how to use fragments to create UIs that automatically adapt to device differences. We look closely at the roll of fragment transactions and how to work with the Android back stack. Leveraging this understanding, we then explore several specialized fragment-related classes like ListFragment and DialogFragment as well as rich navigation features like swipe-based screen browsing.
