iOS: List Tap!

Main Goal

Create a simple (single screen) iOS Swift list app. The app screen is presented below:

You can see all the functionality in this video.

---

Features

• START button at the bottom
• All collection elements have two properties: color and number
• Each red element's displayed value is multiplied by 3
• Each blue element has it's exact value displayed
• There are line separators between elements
• There is no separator below the last element
• Tapping an element adds the model value of the element before it in the collection (modulo number of elements in the collection)
• Pressing START starts a timer which ticks once every second and changes the button to a STOP button
• Each timer tick runs the following logic:

if numberOfElements < 5 then
  appendRandomElement
else
  50% chance -> increment random element
  30% chance -> reset random element counter
  10% chance -> delete random element
  10% chance -> add the model value of the element before it in the collection (modulo number of elements in the collection)
endif

Hints

• Code functionality is as important as its architecture
• Use SwiftUI or UIKit with UICollectionView
• Use Storyboards or write your views from code – it doesn't matter
• Use any external libraries that you want
• Do not copy code without mentioning the author
