Goal was to implement color picker similar to what Lake drawing app has
• Implement the same logic without using UICollectionView(therefore a lot of hacks e.g. returning Int.max for infinite scrolling could be avoided)
• Remove necessity to provide frame at initialization phase
• Render only visible part
• C̶o̶c̶o̶a̶p̶o̶d̶s̶, Cathage, SPM support
My friend implemented Android version which is available here
