Google Maps API: String URL Enconding

I'm using the following code to search for a place:

let correctedAddress:String! = self.searchResults[(indexPath as NSIndexPath).row].addingPercentEncoding(withAllowedCharacters: CharacterSet.symbols)

let url = URL(string: "https://maps.googleapis.com/maps/api/geocode/json?address=\(correctedAddress)&sensor=false")

self.searchResults[(indexPath as NSIndexPath).row] returns a string like this: "São Paulo - State of São Paulo, Brazil"

The string that is the parameter of URL is like this (after the encoding): 

https://maps.googleapis.com/maps/api/geocode/json?address=Optional(\%22State%20of%20S%C3%A3o%20Paulo%2C%20Brazil\%22)&sensor=false

If I search for this URL in my web browser, the JSON is shown. So I assume it is a valid URL, but the URL(string: ..) method always returns nil

I probably need to change my encoding, I tried using CharacterSet.urlPathAllowed but always return nil.

What kind of encoding I should use? Or there is something else wrong?

This worked for me :

"https://maps.googleapis.com/maps/api/geocode/json?address=" + correctedAddress + "&sensor=false"

Try to remove the Optional(...) string in the url

https://maps.googleapis.com/maps/api/geocode/json?address=\%22State%20of%20S%C3%A3o%20Paulo%2C%20Brazil\%22&sensor=false

I believe that's the reason for the URL is returning nil.
