How can I use a # symbol instead of ? in URLQueryItem?

Question

If I create a URL like this:

    guard var urlComponents = URLComponents(url: "https://example.com/something", resolvingAgainstBaseURL: false) else {
        return
    }

    let queryItems = URLQueryItem(name: "token", value: token)
    urlComponents.queryItems = [queryItems]

    guard let urlWithQueryItem = urlComponents.url else {
        return
    }

I want the end result to be something like https://example.com/something#token=7as78f6asd678768asd768asd678

Instead of the default https://example.com/something?token=7as78f6asd678768asd768asd678

(I'm looking for something smarter than a search and replace of the ? character)

Thanks

As others have noted, URLQueryItem object is more intended for use with querystrings vs anchors/fragments. With that said, below is a function that helps you accomplish what your questions is asking.

func constructURL(withURL urlBase: String, andFragmentFromQueryItem queryItem: URLQueryItem) -> URL?{

guard let url = URL(string:urlBase) else {
    return nil
}

guard var urlComponents = URLComponents(url: url, resolvingAgainstBaseURL: false) else {
    return nil
}

let fragmentKey = queryItem.name
let fragmentValue = queryItem.value ?? ""

urlComponents.fragment = "\(fragmentKey)=\(fragmentValue)"

guard let urlWithFragment = urlComponents.url else {
    return nil
}

return urlWithFragment

}

let url = constructURL(withURL:"https://example.com/something", 
andFragmentFromQueryItem: URLQueryItem(name: "token", value: "tokenValue"))
let urlString = url?.absoluteString 
print("\(urlString!)")
