You're using a function Get.JSON. You don't tell us what that is, or what data type the response will be.

I'm guessing that it is type Any, or perhaps [String:Any].

Your code self.sentimentResponse["aggregate"]!["sentiment"]! fails because the compiler does not know what kind of data self.sentimentResponse contains.

You could try casting it to the correct type:

guard let typedResponse  = response as? [String: [String:String]] else {return}
self.sentimentResponse = typedResponse
guard let aggregate = typedResponse["aggregate"] else {return}
guard let sentiment = aggregate["sentiment"] else {return}
DispatchQueue.main.async() {
   self.label.text = sentiment
}

(In the above code I'm using 3 separate guard statements to make debugging easier. You could use one guard statement with 3 separate let statements and accomplish the same thing)
