let pattern = "\\[.*?\\]"
guard let regularExpression = try? NSRegularExpression(pattern: pattern, options: []) else { return nil }
let textCheckingResults = regularExpression.matchesInString(text, options: [], range: NSMakeRange(0, text.characters.count))
if textCheckingResults.count == 0 {
return nil
}
for result in textCheckingResults{
let te = (text as NSString).substringWithRange(result.range)
print(te)
}
return nil
}
