Working with regex in Swift

RegexExample.swift

let text = "Text to get the match"
let regex = NSRegularExpression(pattern: "([^ ]+)", options: nil, error: nil)!
let matches = regex.matchesInString(text, options: nil, range: NSRange(location: 0, length: count(text)))
        
var substring = ""
        
for match in matches as! [NSTextCheckingResult] {
    // range at index 0 returns the full match
    // range at index 1 returns the first capture group
    // range at index 2 returns the second capture group and so on...
    substring = (text as NSString).substringWithRange(match.rangeAtIndex(1))
}

println(substring)
