How to get timeout info from dataTask

I have the following code for requesting data from an external API:

var request = URLRequest(url: myURL!, cachePolicy: .useProtocolCachePolicy, timeoutInterval: 10.0)                 
request.httpMethod = "GET"
request.allHTTPHeaderFields = headers
let session = URLSession.shared
let dataTask = session.dataTask(with: request as URLRequest, completionHandler: { data, response, error in
    if error != nil {
        print(error)
    } else {
        let httpResponse = response as? HTTPURLResponse
    }
})

dataTask.resume()

The timeoutInterval is set to 10.0. But how can I get back info on if the request/session timed out, or how long the request/session took the complete? I will then use that info to determine which function I should call.

Any help is much appreciated!

If the error is not nil then cast error as URLError and check the code is .timeout or not. Here is the code.

var request = URLRequest(url: myURL!, cachePolicy: .useProtocolCachePolicy, timeoutInterval: 10.0)

request.httpMethod = "GET"
request.allHTTPHeaderFields = headers

let session = URLSession.shared

let dataTask = session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in
    if (error != nil) {
        if let error = error as? URLError {
            if error.code == .timedOut {
                print("Timeout error")
            }
        }
        
        print(error)
    } else {
        let httpResponse = response as? HTTPURLResponse
    }
})

dataTask.resume()
