title: Type 'Any' Has no Subscript Members in xcode 8 Swift 3
body: <p>My App is supposed to go to a specific location to pull down the website it needs to load. In 2.3 it worked like a charm, but since I've updated xcode (which I don't have a ton of experience in) it is giving me the error "type 'Any' has no subscript members" and highlighting the "json" right before line three</p>
  
  <pre><code>...Retriever = json["WEB"]...
  </code></pre>
  
  <p>this is the code related to it.</p>
  
  <pre><code>let json = try JSONSerialization.jsonObject(with: data!, options:.allowFragments)
  
        if let Retriever = json["WEB"] as? [[String: AnyObject]] {
  
                   for website in Retriever {
  
                      if let name = website["URL"] as? String {
  
                            self.loadAddressURL(name)
  </code></pre>
  
  <p>I feel like I am missing something small. If there is a better way to do this, I would love suggestions. The URL returns this JSON</p>
  
  <pre><code>{
    "WEB" : [
             {
              "URL" : "http://www.google.com"
             }    
            ]
  }
  </code></pre>
  
  <p>but I would love it if I could simplify it to just</p>
  
  <pre><code>{"URL":"http://www.google.com"}
  </code></pre>
