Beginner's Guide to iOS 13 App Development Using Swift 5.1

This book covers iOS 11 app design fundamentals using the latest Swift 4 programminglanguage, Xcode 9 and iOS 11 SDK.The author assumes you have no experience in app development. The book starts with theinstallation of the required programming environment and setting up the simulators. Then, thesimplest Hello World app is developed step by step. In the next chapter, basics of the Swift 4programming language are given with practical examples. Screenshots and code snippets areclearly given in the book to guide the reader. After the Swift lecture, 7 complete apps(including a 2D game) are developed in seperate chapters. As the reader follows thedevelopment of the example apps, he/she will learn designing user interfaces, connectinginterface objects to code, developing efficient Swift code and testing the app on simulatorsand real devices.Chapters of the book and the contents of these chapters are as follows: Chapter 1. Introduction: General info and the steps of developing an iOS app.Chapter 2. Setting up your development environment: Installing Xcode, setting up signingidentities, viewing/adding simulators and real devices.Chapter 3. Test drive - the "Hello World" app: Creating a new Xcode project, adding andpositioning user interface objects, building the project, running the developed app on thesimulator and on the real device.Chapter 4. Swift programming language: Variables, constants, optionals, arrays, dictionaries, sets, if-else and switch-case decision making statements, for and while loops, functions, classes, objects and inheritance in Swift 3. Each concept is clearly explained stepby step with code examples and screenshots.Chapter 5. Disco lights app: Using buttons and connecting actions to buttons in the code.Chapter 6. Body mass index (BMI) calculator app: Using input boxes, performingcalculations and displaying the results on the screen.Chapter 7. Simple die roller app: Using random number generator functions, includingimage sets in your project, displaying images on the screen and changing the displayed imageusing Swift code.Chapter 8. Exercise calorie calculator app: Using global variables, creating tabbed appsand utilizing segmented controls.Chapter 9. Show my location app: Adding a map object to your app, setting requiredpermissions, accessing GPS device and showing real time location on the map.Chapter 10. S.O.S. sender app: Adding SMS functionality, setting required permissions andsending real time location using SMS.Chapter 11. Bounce the ball game: Basics of SpriteKit that is used to develop 2D iOSgames, adding objects to the game, sensing screen touches, moving game objects according totouches, combining all these and more to develop a complete 2D game.This book includes 212 figures and 101 code snippets that are used to explain appdevelopment concepts clearly.
