How to pass an argument of type struct?

I have defined two structs, Tag and Post. The post struct has an attribute "tag" of type "Tag". I want to create an instance of Post and pass the argumenet of type Tag.

structs.swift 
struct Tag {
    let name:String
}

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

}
//How to pass the argument of type Tag??
let firstPost = Post(title: "A title", author: "The author", tag: )

Create an init method for the Post struct and create an instance of Tag struct inside of it, assigning the instance the name parameter!

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

    init(title: String, author: String, name: String) {

        self.title = title
        self.author = author
        self.tag = Tag(name: name)
    }
