URLs can only contain a certain set of characters. Using other characters can cause such errors. Or even the allowed characters can also sometimes cause this, for example, an '&' is used as a delimiter and cannot be directly used in a URL query parameter value.

You can use this for encoding those chaotic characters :

let newURL = YOUR_URL.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)
let url = URL(string: newURL)
