swift 3 clear version

Save cookies

func saveCookies() {
    guard let cookies = HTTPCookieStorage.shared.cookies else {
        return
    }
    let array = cookies.flatMap { (cookie) -> [HTTPCookiePropertyKey: Any]? in
        cookie.properties
    }
    UserDefaults.standard.set(array, forKey: "cookies")
    UserDefaults.standard.synchronize()
}

Load cookies :

func loadCookies() {
    guard let cookies = UserDefaults.standard.value(forKey: "cookies") as? [[HTTPCookiePropertyKey: Any]] else {
        return
    }
    cookies.forEach { (cookie) in
        guard let cookie = HTTPCookie.init(properties: cookie) else {
            return
        }
        HTTPCookieStorage.shared.setCookie(cookie)
    }
}

You can call these functions like the following code

func webViewDidStartLoad(_ webView: UIWebView) {
    loadCookies()
}

func webViewDidFinishLoad(_ webView: UIWebView) {
    saveCookies()
}

Do not forget to have a delegate of your WebView for webViewDidStartLoad and webViewDidFinishLoad
