How to use Launch Image in your project

There are the various places that we need to use launch image in our project but there is no direct way to use launch images. For this, we have two ways to do the same.

1. Putting all the launch image in Assets separately. This will increase your project size and you have to assign these images manually to UIImageView.

2. Use the same launch images used in the launch image set. I have written an extension for the same.

    static let IS_RETINA           = UIScreen.main.scale >= 2.0
