Defining Structure

• struct MyStruct {...}
• Call/Initialise by: MyStruct()
• Has to start with a Capital Letter since we are defining our own Data Type
• Struct can have properties and it can have behaviours
  • Properties: let name, var citizen, var resources
  • Behaviour: func doSomething() {...}
• When creating a struct file, keep the file name same as the struct
• Method is when a function like is place in a struct. E.g. doSomething()
• Example:

struct Town {
   let name: "Paris Land"
   var citizen = ["PersonOne","PersonTwo","PersonThree"]
   var resources = ["Grain" : 100, "Ore" : 42, "Wool" : 75 ]
   
   func doSomething() {
      print("Defences increased!")
   }

• Initialise by: var myTown = Town()

• Access the elements of Struct:

print(myTown.citizen)
_______RESULT_______
["PersonOne","PersonTwo","PersonThree"]

• Append Elements: myTown.citizen.append("PersonFour")

• Call Method in Struct: myTown.doSomething()

Creating a struct blueprint

struct Town {
   let name: String
   var citizen = [String]
   var resources = [String : Int ]
   
   init(townName: String, people: [String], stats: [String: Int]) {
      name = townName
      citizen = people
      resources = stats
   }
   
   func doSomething() {
      print("Defences increased!")
   }

• To initialise another town: var anotherTown = Town(townName: "Somewhere", people: ["John Doe"], stats: ["Cards" : 40])

• Access the anotherTown:

anotherTown.citizen.append("Wilson")

print(anotherTown.citizen)
_____RESULT______
["John Doe","Wilson"]
