Architecture

A UITabBarController presents NowPlayingViewController (table layout) and SuperheroViewController (collection grid layout) as sibling tabs. Both view controllers fetch independently via URLSession.dataTask and hold their own movies: [[String: Any]] arrays. Tapping any row or cell passes the corresponding dictionary to DetailViewController through a storyboard segue. MovieApiManager is defined as a reusable service layer but view controllers currently call URLSession directly, keeping the networking path straightforward.

Key Implementation

UICollectionViewFlowLayout sizing at runtime: SuperheroViewController.viewDidLoad casts the layout to UICollectionViewFlowLayout, sets minimumInteritemSpacing and minimumLineSpacing to 5 points, then derives itemSize from collectionView.frame.size.width to produce exactly three columns regardless of device width — no hardcoded point values.
