Описание: In this 3 part series we will learn how to implement UICollectionView from scratch using UICollectionViewFlowLayout and UICollectionViewDataSource.
1. Setting and configuring UICollectionViewFlowLayout to show grid based vertical layout with multiple sections.
2. Using UICollectionViewDataSource as the source of data to render in Collection View.
3. Building Self-Sizing CollectionView Cell and supplementary view with auto layout programatically. With Self-Sizing Cell, the app will supports Dynamic Font Type for accessibility.
4. Using Collection View performBatchUpdates to insert, remove, sections and indexPaths in single transaction using Swift 5.1 Collection Diffing API.
5. Using SwiftUI Live Preview on UIKit based UIView and UIViewController for rapid UI prototyping in Xcode.
