title: Using Swift structure property in an objc file
body: <p>I declare a <code>CLLocationCoordinate Property</code> in my swift class.Like</p>
  
  <pre><code>class SomeClass{
      var abc: CLLocationCoordinate?
      var aaa: CLLocation?
  }
  </code></pre>
  
  <p>But,When I init this class in an objective-c file,It says there is no abc property.But my other property such as aaa exist.I guess its because that abc 
  is a structure.How can I solve this problem?</p>
