CocoaPods spec lint raises errors

Question

I've created an iOS framework project and added a .podspec to it. The framework is generated fine as well as the included demo project. But I'm getting errors during the pod spec lint test.

The podspec file I'm using is

Pod::Spec.new do |s|s.name         = "HorizontalPicker"
s.version      = "1.0.0"
s.summary      = "A similar to UIPickerView but horizontal picker view."
s.homepage     = "https://github.com/HHuckebein/HorizontalPicker"
s.license      = { :type => 'MIT', :file => 'LICENSE.txt' }
s.author       = { "RABE_IT Services" => "[email protected]" }
s.source       = { :git => "https://github.com/HHuckebein/HorizontalPicker.git", :tag => "1.0.0" }
s.platform     = :ios, '5.1'
s.source_files = 'HorizontalPicker/*.{h,m}'
s.framework    = 'QuartzCore'
s.requires_arc = true
end

Analyzed 1 podspec.

[!] The spec did not pass validation.

EDIT The directory structure is like so. /HorizontalPicker/HorizontalPicker.podspec /HorizontalPicker/HorizontalPicker/Source Code lives here

Answer 1

To see what happened I used

pod spec lint --no-clean ...

which leaves the generated test pod inside /tmp. So I found QuartzCore was added in the pch file, which is ok for a normal project, but not in the class files.

So it was not the best coding style.

Answer 2

In my case lint was testing the spec against OS X SDK instead of the iOS SDK.

Both platforms have the Security framework but the APIs are not the same, thus the errors.

Just adding s.platform = :ios to the podspec fixed it.
