Q:

Asset Catalog Compiler Warning for no reason

I'm using Xcode 5.1.1 
In images.xassets i'm trying to upload my launch image. It's a 640x960 launch image for iPhone portrait iOS 7 2x and i'm receiving an error stating "An iPhone Retina (4-inch) launch image for IOS7 and later is required". The thing is I created a new launch image called LaunchImage-1 and i uploaded my 640x960 launch image in the same iPhone portrait iOS 7 2x and it's NOT giving me that error. Actually i just had an image inside the regular LaunchImage folder of that size only i decided to change the launch image and now i'm getting this error. I don't know why i'm getting this error out of nowhere. Also when i put in the 640x960 image (as stated by required size) i turn on the simulator and my 4-inch simulator uploads a 3.5 inch screen with top and bottom black.
My current deployment target is for 7.1. Why am i getting this error?

BTW, you can turn the Asset Compiler warnings off if they just annoy you and don't provide anything helpful (as they often seem to do in my experience).
Just go to the Build Settings, to the Asset Catalog Compiler - Options section and turn them off:
