Swift, Check if particular website reachable

How to check reachability of particular website?

I am connected to wifi network for internet access, which have blocked some sites. How to check if I have access to those sites or not?

I have checked with Reachability class, but I can not check for particular website.

Currently I am using Reachability.swift

func pageExists(at url: URL) async -> Bool {
    var headRequest = URLRequest(url: url)
    headRequest.httpMethod = "HEAD"
    headRequest.timeoutInterval = 3
    let headRequestResult = try? await URLSession.shared.data(for: headRequest)
    
    guard let httpURLResponse = headRequestResult?.1 as? HTTPURLResponse
    else { return false }
    
    return (200...299).contains(httpURLResponse.statusCode)
}

I don't know what is the best practice, but I use HTTP request to do so.

func checkWebsite(completion: @escaping (Bool) -> Void ) {
    guard let url = URL(string: "yourURL.com") else { return }

    var request = URLRequest(url: url)
    request.timeoutInterval = 1.0 

    let task = URLSession.shared.dataTask(with: request) { data, response, error in
        if let error = error {
            print("\(error.localizedDescription)")
            completion(false)
        }
        if let httpResponse = response as? HTTPURLResponse {
            print("statusCode: \(httpResponse.statusCode)")
            // do your logic here
            // if statusCode == 200 ...
            completion(true)

        }
    }
    task.resume()
}

The initializer you want to use is listed on that page.

You pass the hostname as a parameter:

init?(hostname: String)
// example
Reachability(hostname: "www.mydomain.com")
