Day 10 of 100 days of SwiftUI

Day 10 of HackingWithSwift's 100 days of SwiftUI. Today I learnt about classes in Swift. Classes in Swift are very similar to
Struct since they allow you to create custom data types with properties and methods. Classes in Swift are different from Structs in two major way:

• Classes are reference-based objects while Structs are value-based objects.
• Classes also introduce a new concept called Inheritance. Swift structs do not support inheritance.

Inheritance means you can create new classes(child classes) based on an existing class (parent classes). The child class will inherit properties and methods from its parent class.

class Developer {
  var name: String
  var occupation: String
  init(name: String, occupation: String) {
        self.name = name
        self.occupation = occupation
    }
}

class AndroidDeveloper {
    var name: String
    var knowsCompose: Bool
     init(name: String, knowsCompose: Bool) {
       super.init(name: name, occupation: "Android developer")
       self.knowsCompose =  knowsCompose
    }
}

let androidDev = AndroidDeveloper("sanmi", false)

The code above creates two classes: Developer and Android Developer. AndroidDeveloper is a subclass of Developer so it inherits the properties: name and occupation from Developer. When creating the init block for AndroidDevelopever, you have to initialise the Developer superclass first.
