title: ObjC delegate callback in Swift
body: <p>In ObjC, I've got a function declared as</p>
  
  <pre><code>-(void)fubar:(void(^)(NSDictionary *))callback;
  </code></pre>
  
  <p>This is how I will use in ObjC</p>
  
  <pre><code>fubar(^(NSDictionary *dict) {
     console.log(dict);
  })
  </code></pre>
  
  <p>How do I use the same in Swift after bridging?</p>
