Summary:
Swift declares NSURLQueryItem.value as a non-optional string. Query item’s values can be nil for query items without an equals sign. This is stated in the NSURL.h header for the queryItems property of NSURLComponents: “If a query's name-value pair has no equals sign, the query name-value pair string is the name and you get a nil value.”

Steps to Reproduce:
Create a URL with a query without an equals sign and try to access the value as shown in the playground code below:



import UIKit

let URL = NSURL(string: "http://danieltull.co.uk?query")
let components = NSURLComponents(URL:URL, resolvingAgainstBaseURL:false)

for queryItem in components.queryItems as [NSURLQueryItem] {
	queryItem.value
}




Expected Results:
Value returns an optional.

Actual Results:
Runtime crash.
