title: Xcode 7.3 Syntax Highlighting and Code Completion issues with Swift
body: <p>I am having an extremely frustrating issue with XCode 7.3 (however, this issue has persisted since I installed XCode 7.2) and Swift code, and I am hoping others have had this issue and know how to resolve it.  Syntax highlighting and code completion work perfectly fine in Objective-C files, and also works fine when calling other Swift objects within Swift code.  However, any Objective-C objects or methods mentioned in Swift code get no syntax highlighting, and XCode will not complete ANY Objective-C declared methods or properties.  Everything compiles and runs just fine.</p>
  
  <p>I should also add that I have also tried doing a completely clean install of XCode.  I deleted all my derived data, deleted all XCode caches, and deleted my XCode preferences files (in addition to obviously deleting the XCode.app archive before re-installing).</p>
  
  <p>It is making it extremely difficult to develop in Swift.  I don't want to do this, but if I can't find a way to resolve this I'll be forced to go back to using Objective-C.</p>
