problems with enumerations course

This is the second time where I've run into the problem of the code Pasan writes not working in Swift 4. It's either because I missed something suuuuuuper simple, but because it's the second time, I'm guessing it's because this is an old course involving Swift 3, whereas I'm running Xcode v9.0.1.

Here's what Pasan wrote (which works) versus what I wrote (pretty sure it's the same): 

struct Person {
    let firstName: String
    let middleName: String?
    let lastName: String

    func fullName() -> String {
        if middleName == nil {
            return firstName + " " + lastName
        } else {
            return firstName + " " + middleName! + " " + lastName
        }
    }

}

let me = Person(firstName: "Pasa", middleName: "Test", lastName: "Premaratne")
me.fullName()

And here's the error I keep getting as the compiler eternally tries to process everything but to no avail:

Playground execution failed:

error: EnumerationsOptionals.playground:2:5: error: expected expression after operator
    }

I copy and pasted this code into my playground and it ran just fine.

A good reason to not update to the latest version of Xcode
