appendingPathExtension(_:)
Returns a URL by appending the specified path extension to self.
Declaration
func appendingPathExtension(_ pathExtension: String) -> URLParameters
- pathExtension:
The extension to append.
Discussion
If the URL has an empty path, such as http://www.example.com, this function returns an unchanged URL.
Certain special characters (for example, Unicode right-to-left marks) can’t be path extensions. If pathExtension contains any of those characters, the function returns an unchanged URL.
