xcode - CocoaPod Storyboard error: -

i made cocoapod include in main project, splash screen animations used while app loading page go to. builds fine in cocoapod project, when include local copy in other projects local folder, following error on storyboard...

error: not enough arguments provided; input document operate on?   

any idea on going on here?

it ended being issue .podspec file. had .source_files spec including not swift file, storyboard.. apparently xcode not cool (shown below)..

spec.source_files = 'cocoapodprojectfolder/source/*.{swift, storyboard}' 

to fix had move storyboard file correct spec: resource_bundle...

spec.source_files = 'cocoapodprojectfolder/source/*.{swift}' spec.resource_bundle = {'cocoapodproject' => 'cocoapodprojectfolder/source/*.{storyboard}'}
