Convert Data to Bool

Question

I have an api call which its response is a data including a bool. it is NOT a JSON object so JSONDecoder fails to decode it. it's some bytes that needs to be converted to a Bool.

  respose in postman: true or false

what is requested :

let dataTask = session.dataTask(with: urlRequest) { responseData, urlResponse, err -> Void in
     let data: Data = responseData
}

thanks for your help in advance

This function should do it:

func parse(data: Data) -> Bool? {
    return String(data: data, encoding: .utf8).flatMap(Bool.init)
}

Try for yourself:

let responseStrings = ["false", "true", "bogus"]
let responseBodies = responseStrings.map { Data($0.utf8) }

responseBodies.map(parse) // => [false, true, nil]
