Swift - How to set cookie in NSMutableURLRequest - swift

Question

I'm trying to set cookie in my HTTP request
and I thought that below code would work:
let request = NSMutableURLRequest(URL: url)
request.HTTPMethod = "GET"
request.setValue("key=value;", forHTTPHeaderField: "Cookie")
but this code is not working.
does anyone have idea how to set it?

Answer 1

Updated answer for Swift 3
You want to look at HTTPCookieStorage.
// First
let jar = HTTPCookieStorage.shared
let cookieHeaderField = ["Set-Cookie": "key=value"] // Or ["Set-Cookie": "key=value, key2=value2"] for multiple cookies
let cookies = HTTPCookie.cookies(withResponseHeaderFields: cookieHeaderField, for: url)
jar.setCookies(cookies, for: url, mainDocumentURL: url)
// Then
var request = URLRequest(url: url)
Original answer for swift 2
You want to look at NSHTTPCookieStorage.
// First
let jar = NSHTTPCookieStorage.sharedHTTPCookieStorage()
let cookieHeaderField = ["Set-Cookie": "key=value"] // Or ["Set-Cookie": "key=value, key2=value2"] for multiple cookies
let cookies = NSHTTPCookie.cookiesWithResponseHeaderFields(cookieHeaderField, forURL: url)
jar.setCookies(cookies, forURL: url, mainDocumentURL: url)
// Then
let request = NSMutableURLRequest(URL: url)

Swift 5
if let cookie = HTTPCookie(properties: [
.domain: ".my.domain.name.com",
.path: "/",
.name: "myCookieNameKey",
.value: "K324klj23KLJKH223423CookieValueDSFLJ234",
.secure: "FALSE",
.discard: "TRUE"
]) {
HTTPCookieStorage.shared.setCookie(cookie)
print("Cookie inserted: \(cookie)")
}

Answer 3

This may be useful for some one(Swift 5).
Avoid using NSMutableURLRequest in Swift. Instead follow the below snippet:
func request(with url: URL) -> URLRequest {
var request = URLRequest(url: url)
guard let cookies = HTTPCookieStorage.shared.cookies(for: url) else {
return request
}
request.allHTTPHeaderFields = HTTPCookie.requestHeaderFields(with: cookies)
return request
}

Here is how it works in Swift 3.x after you set cookie using HTTPCookieStorage
let cookies=HTTPCookieStorage.shared.cookies(for: URL(string: cookieURL)!)
let headers=HTTPCookie.requestHeaderFields(with: cookies!)
let request = NSMutableURLRequest(url: requestURL!)
request.allHTTPHeaderFields=headers
