Build issue for Easy Connect for iOS under Xcode due to missing .pch file

Another build issue with the iOS EasyConnect is that

`error: Build input file cannot be found: '/Users/dgtlrift/Documents/EasyConnect/mobilesdk/ios/Pods/Target Support Files/SwiftKeychainWrapper/SwiftKeychainWrapper-prefix.pch' (in target 'SwiftKeychainWrapper' from project 'Pods')
`

Doing some googling implies that this was initially pushed into the repo with a windows machine containing a `.gitignore` file which had `*.pch` entry based on a Visal Studio template, but there's nothing in root, unless the original push had it in the path but not added to the repo.
