Where should I need to put my @3x image in Launch screen section. There is no placeholder for @3x in Launch Image Section.
Even if I put @3x image in my resource. Its not automatically picking it up. Can anybody tell how can we use @3x image in Xcode 6 for slash.

In your xcassets file you need to check the attribute inspector of the LaunchScreen section. You should be able to check a checkbox saying "iOS8 and Later" (Portrait and Landscape).
When you did this you should see the placeholder Retina HD 5.5 and Retina HD 4.7.
