ReusableKit

Swift CocoaPods Build Status Codecov

Generic reusables for Cocoa. Currently supports UITableView and UICollectionView.

At a Glance

Before 🤢

collectionView.register(UserCell.self, forCellWithReuseIdentifier: "userCell")
collectionView.dequeueReusableCell(withReuseIdentifier: "userCell", for: indexPath) as! UserCell
  1. A hard-coded string identifier can cause a human error.
  2. A force downcasting should be avoided.

After 😊

let reusableUserCell = ReusableCell<UserCell>()
collectionView.register(reusableUserCell)
collectionView.dequeue(reusableUserCell) // UserCell
  1. A string identifier is generated automatically using UUID and stored in the struct.
  2. A generic can ensure the type of the dequeued cell statically.

Example Usage

It is recommended to define reusable types as a static constants in an enum or a struct.

UITableView

// 1. define
enum Reusable {
  static let headerView = ReusableCell<SectionHeaderView>()
  static let userCell = ReusableCell<UserCell>()
}

// 2. register
tableView.register(Reusable.headerView)
tableView.register(Reusable.userCell)

// 3. dequeue
tableView.dequeue(Reusable.headerView, for: indexPath)
tableView.dequeue(Reusable.userCell, for: indexPath)

UICollectionView

// 1. define
enum Reusable {
  static let headerView = ReusableCell<SectionHeaderView>()
  static let photoCell = ReusableCell<PhotoCell>()
}

// 2. register
collection.register(Reusable.headerView, kind: .header)
collection.register(Reusable.photoCell)

// 3. dequeue
collection.dequeue(Reusable.headerView, kind: .header, for: indexPath)
collection.dequeue(Reusable.photoCell, for: indexPath)

RxSwift Extension

ReusableKit supports a RxSwift extension.

users // Observable<[String]>
  .bind(to: collectionView.rx.items(Reusable.userCell)) { i, user, cell in
    cell.user = user
  }
