colors's Issues

Images not found: Assets naming issue vs. color array names issue.

There is a mismatch between the color assets naming, which are in lowercase in the folder, ex. red, green, blue, etc and the color array which has the first letter capitalized, ex. Red, Green, Blue, etc.

This causes the color not to be found and no images are displayed.

In ContentView.swift
struct ContentView: View {
var colors = ["Red", "Green", "Yellow", "Blue", "Pink", "Purple"]
...

It should be
var colors = ["red", "green", "yellow", "blue", "pink", "purple"]

Also, when you run in the terminal, use the new lowercase convention for colors.
$xcrun simctl openurl booted colors://green
