Summary:

Head First Swift Swift is a programming language you can rely on. A language you can present to the family. Safe, reliable, speedy, friendly, easy to talk to, it's the language of choice for Apple's platforms-iOS, macOS, watchOS, and tvOS. But open source Swift also runs on Linux as well as the server, and it's gaining ground in scientific computing and web apps. Swift for Windows is even in the works. You can build everything from mobile apps to games, web apps, frameworks, and beyond. So jump in and get started! What's so special about this book? If you've read a Head First book, you know what to expect-a visually rich format designed for the way your brain works. If you haven't, you're in for a treat. With this book, you'll learn Swift through a multisensory experience that engages your mind rather than a text-heavy approach that puts you to sleep.

Acknowledgments

1. Introducing swift

Swift is a language for everything

The swift evolution of Swift

Swift into the future

How you're going to write Swift

The path you'll be taking

Getting Playgrounds

Creating a Playground

Using a Playground to code Swift

Basic building blocks

A Swift example

Congrats on your first steps with Swift!

2. Swift by name

Building from the blocks

Basic operators

Operating swiftly with mathematics

Expressing yourself

Names and types: peas in a pod

Not all data is numbers

Stringing things along with types

String interpolation

3. Collecting and controlling

Sorting pizzas

Swift collection types

Collecting values in an array

How big is that array, exactly? Is it empty?

Collecting values in a set

Collecting values in a dictionary

Tuples

Everyone needs a good alias

Control flow statements

if statements

switch statements

Building a switch statement

Range operators

More complex switch statements

Getting repetitive with loops

Building a for loop

Building a while loop

Building a repeat-while loop

Solving the pizza-sorting problem

Phew, that's a lot of Swift!

4. Functions and enums

Functions in Swift let you reuse code

Built-in functions

What can we learn from built-in functions?

Improving the situation with a function

Writing the body of the function

Using functions

Functions deal in values.

Many happy returns (from your functions)

A variable number of parameters

What can you pass to a function?

Every function has a type

Function types as parameter types

Multiple return types

Functions don't have to stand alone

Switching with enums

5. Closures

Meet the humble closure

Closures are better with parameters

Boiling it all down to something useful

Reducing with closures

Capturing values from the enclosing scope

Escaping closures: the contrived example

Autoclosures provide flexibility

Shorthand argument names

6. Structures, properties, and methods

Let's make a pizza, in all its glory...

The initializer behaves just like a function

Static properties make structures more flexible

Methods inside structures

Changing properties using methods

Computed properties

Getters and setters for computed properties

Implementing a setter

Swift Strings are actually structs

The case for lazy properties

Using lazy properties

7. Classes, actors, and inheritance

A struct by any other name (that name: a class)

Inheritance and classes

Overriding methods

Final classes

Automatic reference counting

Mutability

8. Protocols and extensions

The Robot Factory

Protocol inheritance

Mutating methods

Protocol types and collections

Computed properties in extensions

Extending a protocol

Useful protocols and you

Conforming to Swift's protocols

9. Optionals, unwrapping, generics, and more

Dealing with something that's missing

Why you might need an optional

Optionals and handling missing data

Unwrapping optionals

Unwrapping optionals with guard

Force unwrapping

Generics

A queue with generics

Here's our new Queue type

10. Getting started with SwiftUI

What's a UI framework, anyway?

Your first SwiftUI UI.

UI building blocks

Making a list, checking it…quite a few times, to get it perfect

User interfaces with state

Buttons are for pressing

Let's see how far you've come

Create a new SwiftUI Xcode project, for iOS

Your Xcode will look something like this

Create a new type to store a todo item in

Make sure each todo item can be uniquely identified

Create a user interface for the app

Implement a way to save the list of todos

So, that's a UI framework?

11. Putting swiftUI into practice

What fancy things can be done with a UI framework?

The Executive Timer UI and features

Creating the basic elements of the app

Pieces of the UI

Setting up the UI of the Executive Timer

Coding the pieces of the UI

Combining the three elements

The finishing touches

Tabbed views for a clean UI

Build a TabView containing your views

Creating a new tabbed ContentView

Creating the tabs and the TabView

Running your new tabbed Executive Timer

12. Apps, web, and beyond

A journey must end...

A recipe for a welcome screen

Step by step assembly of the welcome screen

Share the state

It's time for our old friend...

Building an app with multiple views that share state

Building a two-view score tracker

The ObservableObject

The first view

The second view

The first view, again

A fancy AsyncImage

Meet Vapor, the Swift web framework
