Unable to find a specification for 'EVURLCache' when trying to use 'objective-c' branch

[schmidt9]

In Podfile I specify

pod 'EVURLCache', :git => 'https://github.com/evermeer/EVURLCache.git', :branch => 'objective-c'

but get error message Unable to find a specification for 'EVURLCache'. When I specify another branches (master or Swift2.2) it works

It actually finds branch but cannot download it for some reason, here is piece of log
