Can someone walk me through this problem step by step so i can better understand?

Help please

optionals.swift 
struct Book {
    let title: String
    let author: String
    let price: String?
    let pubDate: String?

}

struct Book { let title: String let author: String let price: String? let pubDate: String?

init(){ title = "some string title manual or from another var if you choose" author = "Name of author(same as above)" price = "10.99(This should be a double not a String really, but string can work also.)" pubDate = "5/18/2016(you should do a NSDate here though" } }

So now if you have a UIlabel in your View Controller and you did:

labelName.text = Book.title

the label will now read "some string title manual or from another var if you choose"
