Assigning array of objects to an object property

Basically after reviewing the code below you will see that I have two structs one for Quotes and the other for People who said them. The Person struct has a property assigning that person all his/her array of quotes. I'm not sure how to do this and its kind of hard to explain but I'm sure you'll get what I'm trying to accomplish. PS: Read the note in the last function.

struct Quote {
    let quote: String
    let attribution: String
    let image: UIImage
}

struct Person {
    let name: String
    let quotes: [Quote]
}

func createQuotes() -> [Quote] {
    var quotes = [Quote]()

    let q0 = Quote(quote: "All that glitters is not gold", attribution: "William Shakespeare", image: #imageLiteral(resourceName: "william_shakespeare"))

    let q1 = Quote(quote: "Hell is empty and all the devils are here.", attribution: "William Shakespeare", image: #imageLiteral(resourceName: "william_shakespeare"))

    let q2 = Quote(quote: "To thine own self be true, and it must follow, as the night the day, thou canst not then be false to any man.", attribution: "William Shakespeare", image: #imageLiteral(resourceName: "william_shakespeare"))

    let q3 = Quote(quote: "Love all, trust a few, do wrong to none.", attribution: "William Shakespeare", image: #imageLiteral(resourceName: "william_shakespeare"))

    let q4 = Quote(quote: "What's in a name? That which we call a rose by any other name would smell as sweet.", attribution: "William Shakespeare", image: #imageLiteral(resourceName: "william_shakespeare"))

    quotes.append(q0)
    quotes.append(q1)
    quotes.append(q2)
    quotes.append(q3)
    quotes.append(q4)

    return quotes
}

func createPeople() -> [Person] {
    var people = [Person]()
    let quotes = createQuotes()

    let williamShakespeare = Person(name: "William Shakespeare", quotes: // how to give Shakespeare his quotes here???)

    return people
}

I must say that I don't really understand the structure of the code. You have two structs, Person and Quote. Both have a property for a name, Attribution in Quote and name in Person. It seems repetitive. Even so... it looks like you could use the quotes constant you already have since the struct "Person" have the property quotes that takes an array of Quote and that's just what an instance of the createQuotes function is. In the createPeople function I'm guessing you are going to append more people saying brilliant things, much like you do in the createQuotes function. Inside the body of a function you don't have to create an instance to append, you could just do it like this: quotes.append(Quote(quote: "All that glitters is not gold", attribution: "William Shakespeare", image: #imageLiteral(resourceName: "william_shakespeare"))). So that's 5 lines of code you don't have to write.
