How do you use "count" and "println" together?

I'm in the Array quiz for SWIFT and receive an error when typing the following code:

var hey: [String] = ["Learn Swift", "Build App", "Deploy App"]

println(" (hey.count)")

Any thoughts? The error just says "Try again"

Hi.

You're missing the backslash before () inside your println statement.

Something like this will work...

println("\(hey.count)")

You can try this

println(hey.count)
