How do I set or remove cookies when making a request with SwiftSoup?

SwiftSoup is a pure Swift library for working with real-world HTML. It provides a very convenient API for extracting and manipulating data, using the best of DOM, CSS, and jQuery-like methods. However, SwiftSoup in itself doesn't handle HTTP requests or responses; it only parses and manipulates HTML content. To make HTTP requests with cookie handling in Swift, you would typically use URLSession.

When you make a request using URLSession, you can set or remove cookies by manipulating the HTTPCookieStorage for your URLSession instance or the shared instance if you are using the default session.

Here's an example of how you might set a cookie before making a request:

import Foundation
// Assuming you've already imported SwiftSoup as well for HTML parsing

// Create a URL
let url = URL(string: "https://example.com")!

// Create a cookie
let cookieProperties: [HTTPCookiePropertyKey: Any] = [
    .domain: url.host!,
    .path: "/",
    .name: "exampleCookieName",
    .value: "exampleCookieValue",
    .secure: "TRUE",
    .expires: NSDate(timeIntervalSinceNow: 3600)
]

// Attempt to create a cookie
if let cookie = HTTPCookie(properties: cookieProperties) {
    // Set the cookie in the shared cookie storage
    HTTPCookieStorage.shared.setCookie(cookie)
}

// Create a request
var request = URLRequest(url: url)

// Use URLSession to make the request
let task = URLSession.shared.dataTask(with: request) { data, response, error in
    // Handle response here
    if let data = data {
        let htmlContent = String(data: data, encoding: .utf8)
        // Now you can parse the HTML content using SwiftSoup
        // ...
    }
}

// Start the network task
task.resume()

To remove a cookie, you can simply delete it from the HTTPCookieStorage:

// Assuming you have a cookie object you want to delete
if let cookie = HTTPCookie(properties: cookieProperties) {
    HTTPCookieStorage.shared.deleteCookie(cookie)
}

Or you can remove all cookies for a specific URL:

if let cookies = HTTPCookieStorage.shared.cookies(for: url) {
    for cookie in cookies {
        HTTPCookieStorage.shared.deleteCookie(cookie)
    }
}

Remember that these operations affect the HTTPCookieStorage, which is persistent across the app's network calls. If you want to make a request without sending any cookies, you can create a custom URLSession with ephemeral configuration:

let ephemeralConfiguration = URLSessionConfiguration.ephemeral
let ephemeralSession = URLSession(configuration: ephemeralConfiguration)

let task = ephemeralSession.dataTask(with: request) { data, response, error in
    // Handle response here
    // ...
}

task.resume()

With the ephemeral session, no cookies are stored, and thus no cookies will be sent with the request. Note that you would still need to parse the HTML content using SwiftSoup after you've obtained it from the network request. SwiftSoup doesn't directly deal with network operations or cookie management.
