Prototype: block-based editor using UICollectionView

[gordonbrander]

Prototype block-based editor using stacked UITextViews and UICollectionView (or similar).

Progress toward #214

UICollectionView is like an updated UITableView, and supports other layouts, such as a grid of images. As of iOS 14, UICollectionView can now do lists as well and is now the recommended approach.

• Updates and replaces UITableView
• More flexible layout and styling than UITableView
• Auto-sizing (self-sizing) of cells is default (unlike UITableView)
  • Build cells with auto layout, and collection view will do the rest automatically.
  • Can still hardcode through preferredLayoutAttributesFittingAttributes
• Buffered rendering of data->view based on scroll viewport
