title: How do I access a file from Xcode’s "Supporting Files" group, in app?
body: <p>I have an app that I've almost finish now that emails, at the end of a data entry flow, two .pdf files. One of these is generated from the entered data, the other is a static file that will be the same in every instance.</p>
  
  <p>The first pdf is generating fine, it's saved to the apps 'documents' folder, and I have successfully attached to to an email for sending. It's the second .pdf, one that I made externally to the app and am trying to add, that is causing me grief.</p>
  
  <p>I've added it to the 'Supporting Files' folder within my Xcode project, but after much searching on here, and elsewhere online, I can't work out how to access that file to be able to add it as an attachment in the email.
  Having "downloaded" the app's data from the Organizer in Xcode, I can see that the file isn't there anywhere; presumably because Xcode can see that the file isn't being used anywhere, it's not adding it at build time (very much an assumption on my part), but I don't know how to reference it anywhere because I don't know where it will be to reference it!</p>
