[QUOTE="renegadeandy, post: 1758498, member: 191510"] Hi everyone! I am new to swift - and new in general to programming on mac osx. I want to get an array of open windows - loop through them and print out to a console each of the names of the open windows. So far I have made a new Cocoa application, in Swift, and in my AppDelegate.swift added the following code: [CODE] import Cocoa @NSApplicationMain class AppDelegate: NSObject, NSApplicationDelegate { func applicationDidFinishLaunching(_ aNotification: Notification) { // Insert code here to initialize your application println("hello world"); CFArray windows = CGWindowListCopyWindowInfo(CGWindowListOption.optionAll, CGWindowID.kCGNullWindowID); } func applicationWillTerminate(_ aNotification: Notification) { // Insert code here to tear down your application } } [/CODE] Needless to say - it doesn't like my println line - can't find the write syntax to just write text to a console :Angry-Tongue: and also - it seems I am not declaring the CFArray correctly - to store the response array of dictionaries from my CGWindowListCopyWindowInfo call. Am I on the right track? What should I change the syntax to? Any pointers would be ace! [/QUOTE]
