Regular Expressions in Swift

Okay.swift

let title = "Regular Expressions in 10 different languages"

// Match
let pattern = ".*\\d.*"
if let match = title.rangeOfString(pattern, options: .RegularExpressionSearch) {
    println("We had a match!")
}

let re = NSRegularExpression(pattern: "(\\d+)", options: nil, error: nil)!
let matches = re.matchesInString(
    title, 
    options: nil, 
    range: NSRange(location: 0, length: count(title.utf16))
)


for match in matches as! [NSTextCheckingResult] {
    let substring = (title as NSString).substringWithRange(match.rangeAtIndex(1))
    println("There are \(substring) languages represented.")
}
