Welcome to Swift Recipes . Swift, announced by Apple at WWDC 2014 and released in September of 2014 is a modern alternative to Objective-C for iOS and OS X developers. In each chapter of this book are recipes or solutions to common situations and challenges you will encounter when developering iOS and OS X applications.

Each chapter follows the same format. A problem is presented, followed by the solution. The solution is discussed in detail in a section named How It Works. This section explains the implementation of the solution using Swift. Code examples and details about how to apply the code are used to walk you through the solution. Finally, in The Code and Usage section, the full listing of the code is provided along with instructions on how to use the full listing.

This chapter will focus on essential recipes you will encounter in Swift. It will provide solutions to common situations you will encounter, such as

Getting Started with Swift
Installing Xcode 6
Working with Playgrounds
Designing User Interface Elements in a Storyboard
Dealing with Strings
Formatting Numbers as Strings
Getting the Length of a Swift String
Manipulating Swift Strings
Manipulating Strings with Native Swift Methods
Storing Strings on the iOS File System
Reading a Text File into a String
Reading and Writing Text Files in Cocoa
Dealing with Numbers
Dealing with Dates

Swift is still a young language. In many of the following recipes, you must use Foundation objects such as NSString and NSDate . Many swift classes are bridged to Foundation objects and can work together seamlessly. Recipes in this chapter leverage those bridged functions.

1.1 Getting Started with Swift

Problem

You have heard and read good things about Swift since it was released, but you are still wondering about the benefits of working with this new language.

Solution

Swift was created by Apple to provide the development community with a new modern programming language. Swift can be used independently or alongside Objective-C to create Mac OS and iOS applications. Swift does have a large number of modern features that Objective-C does not. Some key features of Swift that are missing in Objective-C are

Type Safety. Type safety helps developers avoid the problems inherent with Objective-C and its use of pointers. All types must have a default value. Variables cannot be nil, unless specified by the developer. An optional type variable may be nil or have a value. The keyword optional is used to define an optional variable.
Type Inference. Swift seeks to make coding more efficient, eliminating some of the artifacts that are present in many languages. The complier can determine the type of most variables using the initial value of the variable. This saves programming time and effort by eliminating the need to explicitly type variables in your code.
Enumerations and Structures. Both can have methods and properties, making them more powerful than ever.
Playgrounds. Playgrounds allow developers to write code in real time and see the results. Developers can code without creating a project, workspace or other typical project requirements. Common playground recipes are found later in this chapter.

1.2 Installing Xcode 6

Problem

You have not yet installed Xcode 6.

Solution

Use the Mac AppStore to install Xcode 6.

How It Works

In order to install Xcode 6, you must have a Mac running OS X Mavericks (10.9) or Yosemite. Launch the Mac App Store, and search for Xcode. Xcode can be downloaded for free from the Mac App Store (Figure ). Once there, click Get.

Figure 1-1.

Click Install. Xcode will download and install

1.3 Working with Playgrounds

Problem

You want to quickly write some code to explore an idea.

Solution

Xcode 6 and Swift have a new feature called playgrounds . Playgrounds let you write code and the playground immediately compiles and executes it. This lets you test an idea without having to create a new project or work within your existing project.

How It Works

Your first step is to launch Xcode. To create a new playground, select File New Playground. Provide a name for your playground and for this recipe, choose iOS as the platform. Next click continue, and then select a location for your saved playground file (Figure ).

Figure 1-2.

Select New from the file menu and then select Playground in the submenu

Xcode will open a playground window containing sample code. A playground window consists of these areas: the code area on the left, the results sidebar on the right, and the Assistant Editor, which is hidden by default. To see the Assistant Editor, select View Show Toolbar. Then click the assistant editor icon that looks like a tuxedo. This will open the Assistant Editor to the right of the results sidebar (Figure ).

Figure 1-3.

The Playground window

The Code and Usage

Working with a playground is designed to be easy. Start writing code in the code editor. Begin with the sample code that Apple has provided:

// Playground - noun: a place where people can play

import UIKit

var str = "Hello, playground"

The first line is a comment, the second line imports the UIKit framework so that you can access those APIs if you wish, and finally the third line creates a new string variable. If you look, on the same line as the string declaration, in the results sidebar, you will see Hello, playground. This is the evaluation of the statement var str = "Hello, playground" . The result of that expression is the string Hello, playground.

Add a new variable called welcome and assign it a value such as this one:

var welcome = "Welcome, playground"

The playground will quickly evaluate that statement and display the results on the right column of the window. You will see additional uses for playgrounds in coming recipes.

1.4 Designing User Interface Elements in a Storyboard

Problem

You need to design a user interface element, but you dont want to compile and run an application to do so.

Solution

Playgrounds provide visualization tools that will display UI objects as they would appear in a real application.
