swift_lint.swift:13:57: error: cannot convert value of type 'Tag.Type' to expected argument type 'Tag'

Hi Fiodar,

You're fine with your code except with the tag parameter. The constructor for Post takes three parameters. both title and author are of data-type, String. In your example code you have passed in an empty string to those parameters, which is fine.

The third parameter, tag needs an instance of data type Tag. This means that you need to create an instance of Tag in your call to the constructor of Post. Currently, you have passed an empty string into the tag parameter. If we look at the class itself, Tag does only require a string to be 'complete'. However, we need to call the constructor.

So, just as you have called the Post constructor by using the Post(title: "", author: "") format, you need to do the same for the Tag class. A Tag wants a string so can be created with a constructor call like, Tag(name: "string").

Insert that into your creation of a Post looks like:

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

You may want to amend your first two strings to pass the tests the challenge is wanting, i.e. change the empty strings to something it is asking for - don't know. But, doing the above will pass an instance of Tag into the Post constructor, rather than just a string.

I hope that helps - let me know if you have questions. Just ask, I will try to help further.

It would be nice to have gone over the Tag type before this. It's not in the iOS beginner track. I tried sorting through it in Xcode, but Tag isn't recognized as a data type in Xcode 8. The only google posts pertaining to this mystery data type that came up in a quick google search were treehouse posts.

Thank you Steve!

I see that now thanks. I came here to delete my comment lol

Because the Tag needs to be set as well. Thanks Steve!

struct Tag {
    let name: String
}

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

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

I Need help! Dont understand what to do with that tag, keep gettng an error on it.
