body: <p>I'm having some trouble accessing a Swift Singleton from Objective-C.</p>
  
  <pre><code>@objc class SingletonTest: NSObject {
  
      // swiftSharedInstance is not accessible from ObjC
      class var swiftSharedInstance: SingletonTest {
      struct Singleton {
          static let instance = SingletonTest()
          }
          return Singleton.instance
      }        
  }
  </code></pre>
  
  <p>swiftSharedInstance can not be reached.</p>
