Swift - The Basics
var languageName: String = “Swift”

var version: Double = 1.0

var introduced: Int = 2014

var isAwesome: Bool = true
Constants &Variables

let languageName: String = “Swift”


let introduced: Int = 2014

let isAwesome: Bool = true

Swift - The Basics

var languageName: String = “Swift”


var introduced: Int = 2014

var isAwesome: Bool = true
Type Inference

let languageName:“Swift”

var version = 1.0

let introduced = 2014

let isAwesome = true

Swift - The Basics
Strings
let someString = “I appear to be a string”

// inferred to be of type String

!
urlRequest.HTTPMethod = “POST”

!
let components = “~/Documents/Swift”.pathComponents

// [“~”,“Documents”,“Swift”]

Swift - The Basics
Characters
for character in “chicago” {

printIn(character)

}

!
c
h
i
c
a
g
o

Swift - The Basics
Building Complex Strings
let a = 3, b = 5

!
// “3 times 5 is 15”

!
let mathResult = “(a) times (b) is (a * b)”

!
// “3 times 5 is 15”

!

Swift - The Basics
Array & Dictionary
let components = “~/Documents/Swift”.pathComponents

// [“~”,“Documents”,“Swift”]

// returns an Array, not an NS array

Swift - The Basics
Typed Collections
var names: String [ ] = [“Aaron”,“Anne”,“Bill”,“Jim”]
var names = [“Aaron”,“Anne”,“Bill”,“Jim”]

// an array of String values
var numberOfLegs = [“dog”: 4, “spider”: 8, “zebra”: 4]

// an Dictionary with String keys and Int values

Swift - The Basics
Modifying an Array
var shoppingList = [ “Butter” , “Carrots” ]

printIn(shoppingList[0])

shoppingList += “Sugar”

shoppingList += [ “Salt” , “Pepper” , “Thyme” ]

shoppingList[1] += “Three carrots”

shoppingList[4…6] += [ “Sage” ,“Rosemary” ,“Garlic” ]

[ “Butter” , Carrots” ]

[ “Butter” ,“Carrots” ,“Sugar” ]

[ “Butter” ,“Carrots” ,“Sugar” ,“Salt” ,“Pepper” , Thyme” ]

[ “Butter” ,“Three carrots” ,“Sugar” ,“Salt” ,“Pepper” ,
Thyme” ]

[ “Butter” ,“Three carrots” ,“Sugar” ,“Sage” ,“Rosemary” ,
Garlic” ]

Swift - The Basics
Modifying a Dictionary
var numberOfLegs = [“dog”: 3, spider”: 8, “zebra”: 4]

numberOfLegs[“snake”] = 0

numberOfLegs[“dog”] = 4
[ “dog”: 3,“spider”: 8, “zebra”: 4]

[ “dog”: 3,“spider”: 8, “zebra”: 4, “snake”: 0]

[ “dog”: 4,“spider”: 8, “zebra”: 4, “snake”: 0]

Swift - The Basics
RetrievingValue from a Dictionary using Optionals
var numberOfLegs = [“dog”: 4, spider”: 8, “zebra”: 4]

!
let possibleLegCount: Int? = numberOfLegs [ “ant” ]

!
if possibleLegCount == nil {

printIn(“Ant wasn’t found”)

} else {

let legCount = possibleLegCount!

printIn(“An ant has (legCount) legs”)

}
