How do I convert url.query to a dictionary in Swift?

Question

I have a URL coming in to the AppDelegate method:

func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) ->

Try this alternatively:

extension URL {
    var queryDictionary: [String: AnyObject]? {
        return URLComponents(url: self, resolvingAgainstBaseURL: false)?
            .queryItems?
            .reduce([:], combine: { (lastResult: [String: AnyObject], queryItem) -> [String: AnyObject] in
                var result = lastResult
                if queryItem.value?.containsString(",") ?? false {
                    let array = queryItem.value?.componentsSeparatedByString(",")

                    result[queryItem.name] = array
                }
                else {
                    result[queryItem.name] = queryItem.value
                }

                return result
            })
    }
}
