if your constant address has not been previously declared in your code you can do that perfectly, all you need to check that country, city and state are previously declared: let state = "im in a state" let city = "im in a city" let address = state + " " + city

You could do this. However there is a cleaner way used throughout the Swift community:

let address = "\(country) \(state) \(city)"

This is called String interpolation, if you want to google it. :)
