Swift: cannot convert value of type <> to expected argument type <> when setting up a selector

I'm getting this error:

cannot convert value of type nsdictionary to expected argument type string

enter image description here
Here is my code:

let json:NSDictionary = try JSONSerialization.jsonObject(with: dataResponse, options: []) as! NSDictionary
self.performSelector(onMainThread: Selector(updateUIwithJsonResponse), with: json, waitUntilDone: true)

performSelector is calling this function: 

func updateUIwithJsonResponse(json:NSDictionary) {
print(json)
}

Any of you knows why I'm getting this error?

Your method takes a parameter, so try

self.performSelector(onMainThread: #selector(updateUIwithJsonResponse(json:)), with: json, waitUntilDone: true)
