In Xcode 6 with Swift it seems that you can set a class and a module for the launch screen. Also you can set outlets like labels, but if I try to create a property with the outlet, the issue navigator shows "Illegal configuration. Launch screens may not have connections". So my question is:
What's the purpose of setting the file's owner class for this screen?
Launch Screen is a just Static Plain design view. iOS8 give you opportunity to design splash screen with your own way (Reduce designer cost and time!!!!!). You can not change it's value at run time. As per my Understand, If you create a connection with your UIViewcontroller or any other class then you can change it's value at run time. So Launch screen has a plain .xib nothing else. If you need more help then let us know.
