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" => "info@berndrabe.de" } 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 -> HorizontalPicker (1.0.0) - ERROR | [xcodebuild] HorizontalPicker/HorizontalPicker/HPickerView.m:42:30: error: unknown type name 'CAShapeLayer' - ERROR | [xcodebuild] HorizontalPicker/HorizontalPicker/HPickerView.m:42:1: error: property with 'retai…

So it was not the best coding style.
