Stay motivated and overcome obstacles while learning to use Swift Playgrounds and Xcode 10.2 to become a great iOS developer. This book, fully updated for Swift 5, is perfect for those with no programming background, those with some programming experience but no object-oriented experience, or those that have a great idea for an app but haven't programmed since school.Many people have a difficult time believing they can learn to write iOS apps. Swift 5 for Absolute Beginners will show you how to do so. You'll learn Object-Oriented Programming (OOP) and be introduced to User Interface (UI) design following Apple's Human Interface Guidelines (HIG) using storyboards and the Model-View-Controller (MVC) pattern before moving on to write your own iPhone and Apple Watch apps from scratch.What You'll LearnWork with Swift classes, properties, and functions
Examine proper User Interface (UI) and User Experience (UX) design
Understand Swift data types: integers, floats, strings, and booleans
Use Swift data collections: arrays and dictionaries
Review Boolean logic, comparing data, and flow control
Use the Xcode debugger to troubleshoot problems with your apps
Store data in local app preferences and Core Data databases

Who This Book Is ForAnyone who wants to learn to develop apps for the Mac, iPhone, iPad, and Apple Watch using the Swift programming language. No previous programming experience is necessary.
