OSX/Swift Get Frontmost Running Application

I'm new to swift and osx programming in general, and I need help with one thing that I can't seem to find an answer for. I'm trying to get the frontmost application running on a computer through an app. Right now I'm able to detect when a target application opens, but not when it is in front of all other windows or when it goes into the background.
What I have so far is:

var workspace = NSWorkspace.sharedWorkspace()
var applications = workspace.runningApplications
for app in applications {
let x = "LolClient"
if app.localizedName == x {
println("League is open")

That will just tell me when a target app opens. I just need to identify what app is in front of all others... basically which one is recieving keystrokes etc. What code would I need to do this? Thank you in advance.
