How do I handle cookies and storage policies in Swift?

Handling cookies and storage policies in Swift is essential for managing user sessions and preferences effectively. This guide provides an overview of how to work with cookies and storage policies in your Swift applications.

// Example: Setting a cookie in Swift using URLSession
import Foundation

let cookieProperties: [HTTPCookiePropertyKey: Any] = [
    .domain: "example.com",
    .path: "/",
    .name: "session_id",
    .value: "123456",
    .expires: NSDate(timeIntervalSinceNow: 3600) // 1 hour
]

if let cookie = HTTPCookie(properties: cookieProperties) {
    HTTPCookieStorage.shared.setCookie(cookie)
}

// Example: Retrieving a cookie
if let cookies = HTTPCookieStorage.shared.cookies {
    for cookie in cookies {
        print("Cookie Name: \(cookie.name), Value: \(cookie.value)")
    }
}

// Example: Deleting a cookie
if let cookie = HTTPCookieStorage.shared.cookies?.first(where: { $0.name == "session_id" }) {
    HTTPCookieStorage.shared.deleteCookie(cookie)
}
