Literals (Images & Colors) don't work in Xcode

Question

When I try using literals in a Playground, it shows me like this (doesn't show my image):

in above i add image or UIImage literal but doesn't show their contents.\

and also this with colors (I can't even see colors):

Answer 1

When you type Color Literal, a white box appears. In order to set the required colour, tap on that white box to select the colour from Color Picker.

This is what it looks like:

Answer 2

Type #colorLiteral() and #imageLiteral() to see a color picker or image picker respectively.

Note: Image picker will list your images at Assets.xcassets.

Answer 3

Make sure you add to the class import UIKit
