The error I get is add an instance method named fullName() to the struct definition
struct Person {
let firstName: String
let lastName: String
func fullName ( ) -> String {
let fullName: String = (firstName + " " + lastName)
return fullName
}}
let person = Person(firstName: "Tom", lastName: "Brown")
let fulname = person.fullName()

Swift is very picky about spacing. More so than other languages.
If you remove the extra spaces in your function definition, you'll be all set. Should look like this:
func functionName() -> ReturnType {
// function body
}

2,372 PointsHi Greg, I firmed up any spaces I thought may be the issue but, Im still told to add an instance method named fullName() to the struct definition. Xcode seems to compile a variety of the versions I've tried.
struct Person {
let firstName: String
let lastName: String
func fullName () -> String {
let fullName: String = (firstName + " " + lastName)
return fullName
}}
let person = Person(firstName: "Tom", lastName: "Brown")
let fullName = person.fullName()

Your original code in your question had two errant spaces. The code in this comment got rid of one of them (between the parentheses) and added a new errant space (you now have two between String and your opening curly brace). You also have an extra space after your equal sign - there should only be one.
Also note that you don't actually have to do anything with your struct for task 1 (i.e. your last two lines are unnecessary).

39,021 PointsIn the interest of being explicit, here are your extra spaces:
struct Person {
let firstName: String
let lastName: String
func fullName_() -> String _{
let fullName: String = _(firstName + " " + lastName)
return fullName
}}

2,372 PointsYep you were right. Didn't realize extra space = no space. It didn't seem to hiccup or change the compiler in Xcode, so I stared looking everywhere for an answer. Thank Ü for your persistence. ¯_(ツ)_/¯ ॐ

39,021 PointsYeah I think the challenges use a Swift Linter, which is more strict about formatting stuff. Probably a good habit to get into anyway
