Following example is leading to errors and I need another set of eyes.

errors at init, return and var lines

Here is the code.

struct Contact {
    let firstName: String
    let lastName: String
    var type: String

    }

    init(fName: String, lName: String){
        self.firstName = fname
        self.lastName = lname
        self.type = "Friend"
    }

    func fullName() -> String {
        return "\(self.firsName) \(self.lastName)"
}

var person = Contact(fName: "Todd", lName: "Deluca")
person.fullName()

you closed the struct prematurely. the init and fullName methods belong inside the struct. remove the } after the type variable. also amit created firstName and lastName as vars, not constants

struct Contact {
    //make these variables
    var firstName: String
    var lastName: String
    var type: String

    //remove the } that was here

    init(fName: String, lName: String){
        self.firstName = fname
        self.lastName = lname
        self.type = "Friend"
    }

    func fullName() -> String {
        return "\(self.firsName) \(self.lastName)"
}

var person = Contact(fName: "Todd", lName: "Deluca")
person.fullName()

thats because you did not capitalize the n in name. you have fname and lname but in the parameters they are called fName and lName

try:

init(fName: String, lName: String){
    self.firstName = fName
    self.lastName = lName
    self.type = "Friend"
}

I followed your instructions and now am getting errors in the init method; on these lines self.firstname =fname and self.lastName = lname

import UIKit

struct Contact { var firstName: String var lastName: String var type: String

init(fName: String, lName: String){
    self.firstName = fname
    self.lastName = lname
    self.type = "Friend"
}

func fullName() -> String {
    return "\(self.firstName) \(self.lastName)"

} }

var person = Contact(fName: "Todd", lName: "Deluca") person.fullName()

person.firstName = "Tom" person.lastName = "Young" person.fullName()

Thanks Stone. These are probably really basic silly questions but I am new to programming. I appreciate your help. Todd

no problem. I make those kinds of mistakes all the time. syntax errors are easy to make and hard to catch sometimes
