ECSlidingViewController pod installation error

I am trying to import ECSlidingViewController library to my iOS mobile application by using Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '7.0'
pod 'ECSlidingViewController', '~> 2.0.3'

When Im trying to open workspace I get error:

The document "" could not be opened

When Im updating (pod update) I get error too: [!] Oh no, an error occurred.

NEW!!!

I have just found out that error causes symbol "&" in project name. Is it possible somehow to keep name with "&" symbol?

Solution

There was an cocoa pods issue with bad naming. I reported it and this issue will be fixed soon
