These files ahve been used for anothe app I made with the Facebook SDK 4 , PArse 1.7.5, on Swift 1.2. I used XCode 6.
I installed all the packages including Parse, Facebook, and more, using cocoapods.
I did not include the storyboards, but the required butttons for login are easy to understand from reading WelcomeViewController.swift.
