Why wont my solution pass?

I am getting the error Bummer! Make sure your function does not take any parameters and returns a String which is not very helpful because my function does not take any parameters and it both explicitly and implicitly returns a string.

If I run this in Xcode, it returns the name I give it as expected. Why wont Treehouse? Seems like there is one very specific way to get it to pass and I'm just not seeing what that is.

structs.swift 
struct Person {
    let firstName: String
    let lastName: String

    func fullName() -> (String) {
      return "\(firstName) \(lastName)"
    }
}
let ralph = Person(firstName: "Ralph", lastName: "Harris")
print( ralph.fullName() )

// prints "Ralph Harris"

Hi there! You've put the return type in parentheses which is causing the challenge to fail. If I remove your bottom 2 test lines and then remove the parentheses from (String), your code passes.

Take a look:

  func fullName() -> String {  //note the removal of the parentheses around String
      return "\(firstName) \(lastName)"
    }
}

Hope this helps! :sparkles:

Perfect, thanks Jennifer. I just did that myself and it worked. Glad you helped!
