Is there a simple way to make text in a variable bold in Swift?

Question

Let's say this is my label:

@IBOutlet weak var hello: UILabel!

I have these 2 variables:

let greeting = "Hello, my name is"
let name = "Bob"

I want to update my label, so I do this:

hello.text = "\(greeting) \(name)"

If I wanted the name variable to be bold, how would I do this?

I've looked through tons of posts and forum questions and they all only seem to explain how to make specific text inside of a string bold and that doesn't seem to be working.
