LaunchImage in Images.xcassets with Launchscreen.xib

Question

I'm using Xcode 6 with iOS 8 and 7, I have a Launchscreen.xib, and in General Target I've well configured my project :

But I think Launchscreen.xib doesn't work on iOS 7.1.

So I've made LaunchImage in Images.xcassets for other iOS which doesn't support Launchscreen

I don't know why, that makes me 2 warnings :

/Users/../Desktop/ProjectName/ProjectFolder/Images.xcassets: The launch image set "LaunchImage" has 2 unassigned images.

How to fix it and use only Launchscreen.xib (if that works for every iPhone/iPad, or use my two images in LaunchImage (Images.xcassets)

Launchscreen.xib is a feature of iOS 8, so if you are targeting iOS 7 You should add launch images.

What worked for me is to leave Launch Screen File field empty and to use assets catalog with launch images. I tried to use both together but I couldn't make good results...
