Try:
import Cocoa
let s = "hallo\there"
let aas = NSMutableAttributedString(string: s, attributes: nil)
if let rangeOfTab = s.rangeOfString( "\t" ) {
let colour = NSColor.grayColor()
let length = distance(s.startIndex, rangeOfTab.startIndex)
let aRange = NSRange(location: 0, length: length)
aas.addAttribute(NSForegroundColorAttributeName, value: colour, range:
aRange)
}
