can not pass in the value of tag

struct Tag { var name: String = "" }

struct Post {

var title: String = ""
var author: String = ""
var tag = Tag()

init(title: String, author: String, tag name: String) {
    self.title = title
    self.author = author
    self.tag = Tag()
}
func description() -> String {
    let desc = "\(title) by \(author). Filed under \(tag.name)"
    return desc
}

}

var firstPost = Post(title: "iOS Development", author: "Apple", tag: "swift")

let postDescription = firstPost.description()

print(postDescription)

structs.swift 
struct Tag {
    let name: String = "swift"
}

struct Post {
    var title: String = ""
    var author: String = ""
    var tag = Tag()
    init(title: String, author: String) {
        self.title = title
        self.author = author
        self.tag = Tag()
    }
    func description() -> String {
        let desc = "\(title) by \(author). Filed under \(tag.name)"
        return desc
    }

}

let firstPost = Post(title: "iOS Development", author: "Apple")

There are a few errors with your code

  1. Do not change the code that was given to you for the task
  2. You do not need extra empty Strings and tags after declaring your variables
  3. Not sure why you have the parentheses after tag, it is not a function or computed property; therefore, it cannot be called.
  4. You do not need initialization, the task does not ask for this anywhere
  5. In your description method you just need to return the description all in one line, you do not need the extra variable desc
struct Tag {
    let name: String
}

struct Post {

    var title: String
    var author: String
    var tag: Tag


    func description() -> String {

        return "\(title) by \(author). Filed under \(tag.name)"


    }
}

let firstPost = Post(title: "The Task", author: "Jeff", tag: Tag(name: "One"))
let postDescription = firstPost.description()
