问题
How do I get rid of Asset Catalog Compiler Warning "Targeting release prior to iOS 7.0, but all launch images specify a minimum version of 7.0 or later." I have indeed (tried to!) set 7.0 as the minimum. What setting am I missing? Thanks.

This problem happen to you when you develop for iOS before 7
Like my Deployment Target 6
So in images.xcassets
We have two section
AppIcon you must Ensure that you check iOS 6.1 and Prior Sizes // the same for iPad if you target iPad
LaunchImage you must Ensure that you check iOS 6.1 and Prior Sizes
Notice this also solution to people who try submit there application to apple store , he will refuse deliver your app until you add this images to your project
this the Error
An iPhone Retina (4-inch) launch image for iOS 6.x and prior is required when targetting releases prior to 7.0.
