Structures, Methods and Properties

• After we have a Struct, we should initialize and create an actual object we can use

struct Town{

	**//Properties**
	let name = "Maxland"
	var citizens = ["Max", "Tom Brady"]
	var resources = ["Grain" : 100, "Ore": 42, "Wool": 75]

	//**Methods**  or in essence what the object can do 
	func fortify(){
		print("Defenses Incresed!")
	}
}

Here is the object that we can now use to access the properties

//this is an object
var myTown = Town()

//prints the citizens from Town
print(myTown.citizens)

//we can also modify it. This will now add Keanu Reeves no the Citizens 
//for the myTown object 
myTown.citizens.append("Keanu Reeves")

Initializers

Used as blueprint

//blank properties for each attribute that can now be defined as custom property
struct Town {

  let name: String
	var citizens: [String]
	var resources: [String: Int]

	init(townName: String, people: [String], stats: [String: Int]){
		name = townName
		citizens = people
		resources = stats
	}
}

//object is created from the blueprint
var anotherTown = Town(townName: "Nameless Island", people: ["Tom Hanks"],
     stats: ["Coconuts": 100])

//Can now tap into the properties of the object 
anotherTown.citizens.append("Wilsin")

It’s a better practice to do it this way for init…

Using self refers to the Struct’s property and the entirety of the structure

init(name: String, citizens: [String], resources: [String: Int]){
		self.name = name
		self.citizens = citizens
		self.resources = resources
	}
