Basic Structure of Class in Swift

// Define a class representing a Student
class Student {
    // Properties/Attributes
    var name: String
    var age: Int
    var grade: String
    
    // Constructor (initializer)
    init(name: String, age: Int, grade: String) {
        self.name = name
        self.age = age
        self.grade = grade
    }
    
    // Method to display information about the student
    func displayInfo() {
        print("Student Name: \(name), Age: \(age), Grade: \(grade)")
    }
    
    // Additional Attribute
    var school: String = "ABC School"
}

// Create an object of the Student class
let myStudent = Student(name: "John", age: 18, grade: "12th")

// Accessing the school attribute
print("Student's School: \(myStudent.school)")

// Call the method to display information about the student
myStudent.displayInfo()

1. What is Class

In object-oriented programming (OOP), a class is a blueprint or template for creating objects (instances). It defines the properties (attributes) and behaviours (methods) that all objects of that type will have.

2. What is Object

In object-oriented programming (OOP), an object is a fundamental concept representing a real-world entity or abstraction. An object is an instance of a class, and it encapsulates both data (attributes or properties) and behaviours (methods or functions) that operate on that data.

Or

A variable that refers to a class.
