get the value of a specific query item within NSURL

NSURL+Query.swift

extension NSURL {
    func getQueryItemValueForKey(key: String) -> String? {
        guard let components = NSURLComponents(URL: self, resolvingAgainstBaseURL: false) else {
            return nil
        }
    
        guard let queryItems = components.queryItems else { return nil }
        return queryItems.filter {
            $0.name == key
        }.first?.value
    }
}

Is it available for Objective-C?

Didn't tried but i cant see any reason it won't work with ObjC.

This will fail if the query-param key has a case mismatch.
I would suggest improving it to:
$0.name.lowercaseString == key.lowercaseString

I don't know if you always want a case insensitive check for your keys.
you can add extra parameter with a default value for case sensitive/insensitive check.
func getQueryItemValueForKey(key: String, isCasesensitive casesensitive: Bool = false ) -> String?
and apply the correct logic in the body of the function

very nice. thanks!
