Extracting value with backlash from string value swift

Question

Hi am trying to get values of a string which is imputed in the form "40|LQ,FP,MD,GR \"Dinner out\"". The string value I am trying to extract is Dinner out the text could be different though like ride in but it still follows the same pattern. how can I extract this string value from the rest of the character using regex of any alternative.

Is the start of the string always the same? Should the quotes be included in the extracted string?` — Joakim Danielson, Mar 15 '20 at 18:13

You can try

var text =  "40|LQ,FP,MD,GR \"Dinner out\""

var regex = try? NSRegularExpression(pattern: "\\\".+?\\\"", options: [])

var matches = regex?.matches(in: text, options: []
    , range: NSMakeRange(0, text.count)) ?? []

for match in matches {
    let r = (text as NSString).substring(with: match.range)
    print("found= \(r)")
}
