cocoapods-catalyst-support: Runtime error when using use_modular_headers

Hi!

Thanks for writing those articles and making this repo. I’m trying to use this now, but I get this error:

#### Unsupported Libraries ####
["TwitterKit"]
[!] An error occurred while processing the post-install hook of the Podfile.

I added this at the end of my Podfile:

def debug
  true
end

def catalyst_unsupported_pods
  [
    'TwitterKit'
  ]
end

post_install do |installer|
  installer.configure_support_catalyst
end

and then run pod install

Thanks!
