title: Swift 3 @objc interference issue not being fixed :-(
body: <p>Before this gets marked as duplicate, <strong>I've already checked <a href="https://stackoverflow.com/questions/44379348/the-use-of-swift-3-objc-inference-in-swift-4-mode-is-deprecated">The use of Swift 3 @objc inference in Swift 4 mode is deprecated?</a></strong></p>
  
  <p>I'm resuming development on app which I had been working on before Xcode 9 (with Swift 4) was released.</p>
  
  <p>I'm getting the build time warning "The use of Swift 3 @objc inference in Swift 4 mode is deprecated. Please address deprecated @objc inference warnings, test your code with “Use of deprecated Swift 3 @objc inference” logging enabled, and then disable inference by changing the "Swift 3 @objc Inference" build setting to "Default" for the "Rushed" target."</p>
  
  <p>I know how to turn on/off/default the build setting but even when I turn it on and then 'default' it, the warning is still appearing.</p>
  
  <p>Scrolling through my files, there are no warnings/yellow triangles which could tell me where the issue is occurring and there's no 'Fix' button appearing.</p>
  
  <p>Please help!</p>
