Calling Instances with custom data types

Hi guys I'm having difficulties with this current task, I feel like everything is ok but I'm probably missing some simple syntax.

I keep getting the error message:

swift_lint.swift:19:50: error: cannot convert value of type 'Tag.Type' to expected argument type 'Tag' let firstPost = Post(title: "", author: "", tag: Tag)

any help would be appreciated.

structs.swift
struct Tag {
  let name: String
}

struct Post {
  let title: String
  let author: String
  let tag: Tag

}

let firstPost = Post(title: "", author: "", tag: Tag)

Hi, your code looks good except the last part where you are assigning a value to "tag". Since you want to give "tag" a value of "Tag", you have to give an instance for the stuct "Tag" as well. Hope that helped. My code that passed the challenge is below:

struct Tag {
  let name: String
}

struct Post {
  let title: String
  let author: String
  let tag: Tag
}

let firstPost = Post(title: "", author: "", tag: Tag(name: ""))
