How to encode url string properly to avoid question mark (?) from being %3F in swift?

Question

I'm sending a request to server using Alamofire pod.

var urlComponents = URLComponents(string: "/hotel/v2")!
urlComponents.queryItems = [
     URLQueryItem(name: "page", value: page)
]
let urlString = urlComponents.url?.absoluteString
var urlRequest = URLRequest(url: url.appendingPathComponent(urlString))

The problem begins when I print out the urlRequest. It shows as :

Then the request reach the backend and the backend returns me some error.

I think the issue is that you're calling `appendingPathComponent`, when that's actually a query component — Alexander, Jan 11 '19 at 04:52
@Alexander , appendingPathComponent is just to combine "devapi.myproject.com" and "/hotel/v2" . — Zin Win Htet, Jan 11 '19 at 04:54
I understand, but as I said, what you're appending *isn't a path component* — Alexander, Jan 11 '19 at 18:43

Don't use url.appendingPathComponent. You have created a URLComponents. Use it properly.

var urlComponents = URLComponents(string: url)!
urlComponents.path = "/hotel/v2"
urlComponents.queryItems = [
     URLQueryItem(name: "page", value: page)
]
var urlRequest = URLRequest(url: urlComponents.url!)

Here I am assuming that url is something like "https://somedomain.com".

You can simply do this - Swift 4 & 5

let url = URL(string: APIServant.API_DEV_URL + path)!
var urlRequest = URLRequest(url: url)
