Launch Finder window with specific files selected

Question

I\'m trying to programmatically launch an OS X Finder window from an Xcode project. I need the window to open to a specific folder and have specific files within that folder

Answer 1

Swift version:

let paths = ["/Users/peter/foo/bar.json"]
let fileURLs = paths.map{ NSURL(fileURLWithPath: $0)}
NSWorkspace.sharedWorkspace().activateFileViewerSelectingURLs(fileURLs)
