What is the iOS platform Images.xcassets folder and why has it replaced the Resources folder?

I have had some problems with building an iOS application, specifically with the icons and splash screens.

If I create a simple project, ionic start TestApp, it creates me a new project, fine. Then I run ionic platform add ios. If I then look in the platform/ios/TestApp directory I would expect to see the Resources folder, however it has actually created an Images.xcassets file/folder which is referenced by the Xcode project. The problem here is that the config.xml is referencing paths to icon.png which supposedly do no exists and when I click the ‘Upload to app store’ button, I get an error about this!

Very frustrating!! Has something changed on purpose or accidentally with the ionic CLI?

Anyone able to help?
