RestKit.h never found in Xcode project

问题

I've tried everything to fix this issue but, despite about 100 'solutions' online, nothing has worked. I'm now worried that I'm altering core files without a clue what I'm doing and that something will ultimately render the entire project dead.

Is it a simple and safe procedure to re-install RestKit to the project by removing it from the podfile then adding it back in? Or is that wishful thinking?

EDIT:

Found a working version from 2 weeks ago
Copied it successfully
Still Builds
Installed Pod 'PageMenu' via the following addition to Podfile under existing lines.

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
use_frameworks!

pod 'PageMenu'

Cleaned up the errors on PageMenu swift file.
Build results in the RestKit.h file not being found.

So guess something in my pod install is seriously killing my project.

Any further ideas? Thanks
