Encode your URL then create request.

let urlString = "http://ws.audioscrobbler.com/2.0/?method=artist.search&artist=\(nameOfArtist)&api_key=bad5acca27008a09709ccb2c0258003b&format=json"        
if let encoded = urlString.addingPercentEncoding(withAllowedCharacters: .urlFragmentAllowed),let url = URL(string: encoded)
 {
     Alamofire.request(url).validate().responseJSON { (json) in
         print(json)
         //Enter your code here
     }
}
