[QUESTION] Errors with version 0.4.0

After updating my project to the 0.4.0 version I get the following errors after cleaning build folder and building:

header "PickerView-Swift.h" not found. This file name is not referenced in my project. Also indicates: Could not build Objective-C module 'PickerView'. Which seems to be related to the header file not found. Note that my project is Swift 4.2 not Objc, except for one pod which is objc.

Hi @neilt,

This is happening because you are installing libraries built with different Swift versions.

Take a look at this issue in the CocoaPods repo and at this blog post and you'll have an idea of what's going on.

TL;DR you'll need to add a post installer script to your Podfile in order to support multiple Swift version dependencies. You'll end up with something like that at the end of your Podfile:

post_install do |installer|
  swift42Targets = ['PickerView']
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['SWIFT_VERSION'] = '4.1'
    end
    if swift42Targets.include? target.name
      target.build_configurations.each do |config|
        config.build_settings['SWIFT_VERSION'] = '4.2'
      end
    end
  end
end

Please note that the script for your specific case might change based on the versions of Swift that your dependencies are using.
