A Step by Step Guide to Building iOS 14 Using Swift 5.2 and Xcode 12 for Beginners 


CHAPTER ONE

INTRODUCTION TO SWIFT


During WWDC 2020, one of the biggest and most exciting moments was the SwiftUI release announcement. SwiftUI is a completely new framework that allows you to design and develop user interfaces with less coding, in a declarative way.

Unlike UIKit, which is usually used in conjunction with storyboards, SwiftUI is completely code-based. However, the syntax is very easy to understand and the project can be quickly previewed using the Automatic Preview.

Since SwiftUI uses the Swift language, it allows you to create applications of the same complexity with much less code. Moreover, using SwiftUI automatically allows the application to use features such as Dynamic Type, Dark Mode, Localization and Accessibility. Plus, it's available on all platforms including macOS, iOS, iPadOS, watchOS, and tvOS. So now your UI code can be in sync across all platforms, giving you more time to focus on your non-core platform specific code.

What is Swift?


Swift is a powerful and intuitive programming language suitable for macOS, iOS, watchOS and Apple tvOS. The process of writing Swift code is full of fun and interaction. Swift has concise syntax but strong expressiveness, and includes modern features that developers love. Swift code is designed to be safe, and at the same time, software that runs lightning fast can be developed.

Modernization


Swift is the latest research result of programming languages and incorporates decades of experience in building Apple platforms. Named parameters are expressed in a concise syntax, making it easier to read and maintain APIs

written in Swift. You don’t even need to type a semicolon. Inferred types make code more concise and less error-prone; modules eliminate headers and provide namespaces instead.

In order to provide the best support for international languages and emojis, strings will maintain Unicode correctness and use UTF-8 based encoding to optimize performance in various use cases. The memory is automatically managed by a rigorous deterministic reference count, which minimizes memory usage and does not generate garbage collection overhead.
