percentEncodedQuery
The query URL component expressed as a URL-encoded string, or nil if not present.
Declaration
var percentEncodedQuery: String? { get set }Discussion
For example, in the URL http://www.example.com/index.php?key1=value1&key2=value2, the query string is key1=value1&key2=value2.
If you set this value to something that is not a valid, percent-encoded string, this class throws an exception.
