i need help

We learned about instance methods before. For this task, add an instance method to Post.

Name the method description. It takes no parameters and returns a string that describes the post instance. For example given a title: "iOS Development", author: "Apple", and a tag named "swift", the description would read as follows"

"iOSDevelopment by Apple. Filed under swift"

Once you have an instance method, call it on the firstPost instance and assign the result to a constant named postDescription

I don't know what to do please help

here is the answer, i guess u already accomplished it(due to the long time you've posted it until now, that i'm posting it), but, just for the record and for someone else that may be looking for the answer : 

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.init(title: "IOS Development", author: "Apple", tag: Tag.init(name: "switf"))
let postDescription = firstPost.description()
