Can you share the podspec for "stickynote" as well, please? It most likely has a syntax error that isn't handled gracefully.

[rafaeldecker]

Hi, I've updated cocoapods and then I've started to receive the same error.

By debugging it, I've found the dependency that is shotting this error is the 'Core'. Take a look into my podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '7.0'
def a  
    pod 'LXReorderableCollectionViewFlowLayout', :git => 'https://github.com/winkapp/LXReorderableCollectionViewFlowLayout.git', :commit => "be2dbf4766b9308e7d1e568bee5fae0a02ed6873"
    pod 'Core', :git => 'https://git.domain.core.git', :commit => 'e409bae'
    pod 'Fabric'
    pod 'Crashlytics'
    pod 'DTCoreText'
    pod 'TTSwitch', '0.0.6' 
end

target 'a-test' do
    a
end

target 'a-stage' do
    a
end

target 'a-live' do
    a
end`

If I comment the Core, it works properly.

The core pod spec is like this:

Pod::Spec.new do |s|

  s.name         = "Core"
  s.version      = "2.0"
  s.summary      = "Basic code for projects."
  s.author       = { "Lorem" => "[email protected]" }
  s.platform     = :ios, "7.0"
  s.requires_arc = true

  s.source       = "~"
  s.source_files  = "Core", "Core/**/*.{h,m}"
  s.resources = ['Core/**/_.{png,xib}']
  s.resource_bundle = { 'Core-Localization' => 'Core/Core/Localization/_', 'Core-Fonts' => 'Core/Core/Fonts/*'}

  s.dependency "ACEDrawingView", "1.3.7"
  s.dependency "AFNetworking", "2.6.1"
  s.dependency "AFOAuth2Manager", "2.2.0"
  s.dependency "PSAlertView", "2.0.3"
  s.dependency "CocoaLumberjack", "2.2.0"
  s.dependency "EDStarRating", "1.1"
  s.dependency "FMDB", "2.5"
  s.dependency "FXImageView", "1.3.5"
  s.dependency "LXReorderableCollectionViewFlowLayout", "0.1.1"
  s.dependency "MBProgressHUD", "0.9.1"
  s.dependency "PSTAlertController", "1.1.0"
  s.dependency "SSZipArchive", "0.3.2"

end `

Can you see any syntax mistake on it?

Thanks in advance.

Ah, source needs to be a hash. The linter in Core should handle this better

[rafaeldecker]

I've insert the git repository URL on source and it has worked.
I've also integrated the homepage:

s.homepage = "http://www.domain.com"
s.source = { :git => 'https://git.domain.core.git' }

Thanks
