title: Xcode equivalent of Visual Studio's "Find Source"
body: <p>I am developing on a Qt project, and have installed Qt from their installer onto my computer. In Visual Studio it is simple to debug-step into Qt sources: when I enter a function in an unknown file, it will open a file browser to let me locate the original Qt source code.</p>
  
  <p>Is there an equivalent function in Xcode or LLDB?</p>
