I can't figure out what the problem is. I checked it several times,.

Don't know what the problem is. there's no need to override init method because we aren't modifying any values. I already override the getFullName() method and returned the value.

classes.swift 
class Person {
    let firstName: String
    let lastName: String

    init(firstName: String, lastName: String) {
        self.firstName = firstName
        self.lastName = lastName
    }

    func getFullName() -> String {
        return "\(firstName) \(lastName)"
    }
}

class Doctor: Person{

    override func getFullName() -> String {
        return "Dr. \(firstName) \(lastName)"
    }
}
let someDoctor = Doctor(firstName: "Maheep", lastName: "Chhabra")

They get a bit tricky. For Doctor you return only "Dr." and lastName:

    override func getFullName() -> String {
        return "Dr. \(lastName)"
    }
