Answer 1

recently i faced same problem and i fixed this problem by doing this.I am sure cookie lost happen only if you are using iOS < 11, for this you need to apply some work around as i applied recently.

1- pass updated cookies in response from server side.Whenever it changed from server,

Read cookie from response like this way.

if  let allHttpHeaders = response.allHeaderFields as? [String: String] {
            let cookies = HTTPCookie.cookies(withResponseHeaderFields: allHttpHeaders, for: responseUrl)
            for cookie in cookies {
                if cookie.name == "cookie name" {
                    // compare with old cookie value so it will show your cookie is changed now.
                    if "your_old_cookie_value" != cookie.value {

                            //update cookie in Script and request header
                            // reload your page here again.
                        break
                    }
                }
            }
        }

This is the minimal change by that you can fix cookie lost issue, for iOS >=11 should not be an issue, for ios 11 and above use httpcookiestore
