Swift Syntax overview - Array and Dictionary

We declare arrays in Swift as follows:

var myJobs = String()[]    //empty array
var myBooks = ["bus ride", "computer", "cars", "road to success"]    //initialize Array with values

Accessing it using array:

var bestSeller = myBooks[1]

Dictionary:

var bestBoss = Dictionary < String,Float > ()     //empty dictionary
var bestEmployee = [
       "Kyle" : "computer engineer",
       "Jason" : "web developer", 
       "Azeez" : "designer",
]
