get request from html swift

//To this, we have two main ways of getting information from the web:
//URLSession and NSURLSession
//It is highly reconmened to use URLSession (easier and newer)

//URLSession way:
//(Make sure you have imported Foundation)

let url = URL(string: String)

//This converts the string parameter into a url.

let urlRequest = URLRequest(url: URL)

//This sorts of makes the request

let task = URLSession.shared.dataTask(with: urlRequest) { data, response, error in
	//The URLSessions.shared part gets data from the url using the urlRequest, albeit with some limitations
	//https://developer.apple.com/documentation/foundation/urlsession/1409000-shared
	/*
		data -> data received from the url (if applicable)
		This is more applicable if getting information from an api by json or other forms
		
		response -> response from the web server
		Is of type URLResponse, and can tell us a lot such as the http request code (etc 404) and others

		error -> errors that might pop up 
		Is of type error
	*/
	//For now, we will be focusing on simply getting the data
	if let data = data {
		print(String(data: data encoding: .utf8))
      //Here, we are using utf-8 to decode the data received into a string, so that we can print it out
      //Choose the right kind of encoding, as different encodings can have completely different results
    }
}
task.resume()

//The resume() is so that the request can actually send
