    func fullName(firstName:String, lastName:String ) -> String {
         let bc = firstName + " " + lastName

Hi there,

Your fullName function doesn't need any parameters - it can access the constants held inside the class directly so remove them from the brackets. You can return your expression directly; you don't need to assign the string to the bc constant.

Next, you want to create an instance of Person called aPerson, not nm. Then use the instance called aPerson to called the fullName method and assign the returned string to a constant called myFullName.

Your last two lines need refining to meet those tasks.

You don't need to pass names into fullName, remember.

Let me know how you get on.

Steve.
