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) ->

Use:

guard let urlQuery =  URL(string: "https://en.wikipedia.org/wiki/Query_string?title=Main_page&action=raw")?.query else {
    return
}

let queryArray = urlQuery.characters.split { $0 == "&"}.map(String.init)
var parametersDict: [String: String] = [:]
for queryParameter in queryArray {
    // Split the queryParam into key / value
    let keyValueArray = queryParameter.characters.split{$0 == "="}.map(String.init)
    let key = keyValueArray.first
    let value = keyValueArray.last
    parametersDict.updateValue(value!, forKey: key!)
}

print(parametersDict)
// Prints ["action": "raw", "title": "Main_page"]
