Just like structures, we can use classes to model everyday objects. And the syntax looks awfully similar.

Here’s the basic syntax for creating a class:

class Name {

}

The class keyword followed by a class name creates the class. By convention, the class name is capitalized. And just like structures, classes also contain both properties and methods.

Suppose we are writing a program for a school to keep track of all the students. Then we can create a blueprint for this type of data by using a class.

Here’s a Student class that models a student:

class Student {
  var name: String
  var year: Int
  var gpa: Double
  var honors: Bool
}

The Student class has four properties:

• .name of the type String
• .year of the type Int
• .gpa of the type Double
• .honors of the type Bool

We can also use Swift’s default property values so that the Student class can have predefined values inside the class:

class Student {
  var name = ""
  var year = 0
  var gpa = 0.0
  var honors = false
}

Now when we create a new instance of Student, that instance’s .name will be an empty string "", its .year will be 0, and so on.
