"Make both firstName and lastName private as well.

I don’t understand your comment about “Make both firstName and lastName private as well”.

You mark both of the Student class firstName and lastName properties with the private access control modifier and modify the student’s name in the updateName(firstName: lastName:) method like this:

class Student {
  private var firstName: String
  private var lastName: String
  
  init(firstName: String, lastName: String) {
    self.firstName = firstName
    self.lastName = lastName
  }
  
  func updateName(firstName: String, lastName: String) -> (firstName: String, lastName: String) {
    self.firstName = firstName
    self.lastName = lastName
    return (firstName: self.firstName, lastName: self.lastName)
   }
}

let student = Student(firstName: "Ray", lastName: "Wenderlich")
let fullName = student.updateName(firstName: "Ray", lastName: "Fix")
print(fullName.firstName) // "Ray"
print(fullName.lastName) // "Fix"
