Parsing JSON

When parsing you will be turning the results into a dictionary of objects.
To see how to get the JSON see this post.

Example JSON

{
    "name": "Luke Skywalker", 
    "height": "172", 
    "mass": "77", 
    "hair_color": "blond", 
    "skin_color": "fair", 
    "eye_color": "blue", 
    "birth_year": "19BBY", 
    "gender": "male", 
    "homeworld": "http://swapi.co/api/planets/1/", 
    "films": [
        "http://swapi.co/api/films/6/", 
        "http://swapi.co/api/films/3/", 
        "http://swapi.co/api/films/2/", 
        "http://swapi.co/api/films/1/", 
        "http://swapi.co/api/films/7/"
    ], 
    "species": [
        "http://swapi.co/api/species/1/"
    ], 
    "vehicles": [
        "http://swapi.co/api/vehicles/14/", 
        "http://swapi.co/api/vehicles/30/"
    ], 
    "starships": [
        "http://swapi.co/api/starships/12/", 
        "http://swapi.co/api/starships/22/"
    ], 
    "created": "2014-12-09T13:50:51.644000Z", 
    "edited": "2014-12-20T21:17:56.891000Z", 
    "url": "http://swapi.co/api/people/1/"
}

Then you convert it into a dictionary:

let dict = json as! Dictionary<String, AnyObject>

So you are really dividing up the JSON like this:

Key	Value
String	AnyObject
{
"name":	"Luke Skywalker",	String
"height":	"172",	String
"mass":	"77",	String
"hair_color":	"blond",	String
"skin_color":	"fair",	String
"eye_color":	"blue",	String
"birth_year":	"19BBY",	String
"gender":	"male",	String
"homeworld":	"http://swapi.co/api/planets/1/",	String
"films":	[	Array<String>
	"http://swapi.co/api/films/6/",
	"http://swapi.co/api/films/3/",
	"http://swapi.co/api/films/2/",
	"http://swapi.co/api/films/1/",
	"http://swapi.co/api/films/7/"
	],
"species":	[	Array<String>
	"http://swapi.co/api/species/1/"
	],
"vehicles":	[	Array<String>
	"http://swapi.co/api/vehicles/14/",
	"http://swapi.co/api/vehicles/30/"
	],
"starships":	[	Array<String>
	"http://swapi.co/api/starships/12/",
	"http://swapi.co/api/starships/22/"
	],
"created":	"2014-12-09T13:50:51.644000Z",	String
"edited":	"2014-12-20T21:17:56.891000Z",	String
"url":	"http://swapi.co/api/people/1/"	String
}

To get data out of this dictionary you do something like this:

 
let dict = json as! Dictionary<String, AnyObject>
let name = dict["name"]
let height = dict["height"]

let films: Array = dict["films"] as! Array<String>
let film1 = films[0]
