Day 4: Class vs. Instance

    I think Swift is fine, this passes everything:

    class Person {
    var age: Int = 0

    init (initialAge: Int) {
        if initialAge > 0 {
            age = initialAge
        } else {
            age = 0
            print("Age is not valid, setting age to 0.")
        }
    }

    func amIOld () {
        if age < 13 {
            print("You are young.")
        } else if age >= 13 && age < 18 {
            print("You are a teenager.")
        } else {
            print("You are old.")
        }
    }

    func yearPasses() {
        age += 1
    }
}
