Declare a Class in Swift


// Declare our new class 
class Person {

// We can define class property here
var age  = 25

// Implement Class initializer. Initializers are called when a new object of this class is created
init() { 
   print(“A new instance of this class Person is created.”) 


// We can now create an instance of class Person - an object - by putting parentheses after the class name
let personObj =  Person()

// Once an instance of Person class is created we can access its properties using the dot “.” syntax.
print(“This person age is \(personObj.age)”)
