See my answer here https://stackoverflow.com/a/49492592/4601900

You need to encode it Because your last path component is not looks like plain string 

let testurl = "http://example.com/ΥΠΗΡΕΣΙΕΣ.jpg"


if let  encodedURL = testurl.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed), let url = URL(string: encodedURL) {
    print("valid url")

} else {
   print("invalid url ")
}

Ouptut

valid url

If your print your encodedURL you will get // Here if you print encoded url you will get http://example.com/%CE%A5%CE%A0%CE%97%CE%A1%CE%95%CE%A3%CE%99%CE%95%CE%A3.jpg

You have to encode your String to get a valid URL. You can do this by using String.addingPercentEncoding(withAllowedCharacters: ).

let urlString = "http://example.com/ΥΠΗΡΕΣΙΕΣ.jpg"
guard let encodedString = urlString.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed), let url = URL(string: encodedString) else {
      return
}
print(url)

The encoded URL becomes:

http://example.com/%CE%A5%CE%A0%CE%97%CE%A1%CE%95%CE%A3%CE%99%CE%95%CE%A3.jpg

You need to use a UTF-8 readable format for the URL so for example 

if let url = URL(string: "http://example.com/ΥΠΗΡΕΣΙΕΣ.jpg"){

would be 

if let url = URL(string: "http%3A%2F%2Fexample.com%2F%CE%A5%CE%A0%CE%97%CE%A1%CE%95%CE%A3%CE%99%CE%95%CE%A3.jpg"){

You can use a a code/decode service like http://www.webatic.com/run/convert/url.php to convert these. Or, you can use a url shortner to provide a UTF-8 readable url.
