Not sure how to call on an struct and use in an instance!

I'm stuck and I've tried several different variations but this one eludes me.

In the editor you've been provided with a Tag type.

Create a struct named Post with three stored properties: title of type String, author of type String, and tag of type Tag.

Then create an instance of Post and assign it to a constant named firstPost.

structs.swift 
struct Tag {
  let name: String
}

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

let firstPost = Post(title: "Welcome to my life", author: "Kirby Ziada", tag: "stories")

I think it would help a lot to use Xcode to complete Swift challenges. In this case the compiler would help you write the instance. The tag property isn't written properly. Pay attention that the tag property of Post is of type Tag and not just a String.

struct Tag {
  let name: String
}

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

let firstPost = Post(title: "Welcome to my life", author: "Kirby Ziada", tag: Tag(name: "stories"))

You should now be able to continue to part two of the challenge!

Ah, legend! Thank you. I had a variation very similar to what you provided but I still couldn't wrap my head around it.
