Swift Class

// Using data types:
class Student {
  var name: String
  var year: Int
  var gpa: Double
  var honors: Bool
}


// Using default property values:
class Student {
  var name = ""
  var year = 0
  var gpa = 0.0
  var honors = false
}

A class is used to programmatically represent a real-life object in code. Classes are defined by the keyword class followed by the class name and curly braces that store the class’s properties and methods.
