Reusable 라이브러리 도입 여부

[nomatterjun]

원래는 ReuseIdentifying 프로토콜을 만들어서 쓰고 있어서 적용을 안하려고 했는데
CompositionalLayout을 써서 register하고 dequeue하는 셀들이 많아지다보니까
모아뒀을때 차이가 크더라고..

적용해보는게 어떨까..?

적용 전

let dataSource = MyPageDataSource(configureCell: { _, collectionView, indexPath, items in
  switch items {
  case .giftStats(let reactor):
    guard let cell = collectionView.dequeueReusableCell(
      withReuseIdentifier: FavorGiftStatsCell.reuseIdentifier,
      for: indexPath
    ) as? FavorGiftStatsCell else { return UICollectionViewCell() }
    cell.reactor = reactor
    return cell
  case .setupProfile(let reactor):
    guard let cell = collectionView.dequeueReusableCell(
      withReuseIdentifier: FavorSetupProfileCell.reuseIdentifier,
      for: indexPath
    ) as? FavorSetupProfileCell else { return UICollectionViewCell() }
    cell.reactor = reactor
    return cell
  case .prefers(let reactor):
    guard let cell = collectionView.dequeueReusableCell(
      withReuseIdentifier: FavorPrefersCell.reuseIdentifier,
      for: indexPath
    ) as? FavorPrefersCell else { return UICollectionViewCell() }
    cell.reactor = reactor
    return cell
  case .anniversary(let reactor):
    guard let cell = collectionView.dequeueReusableCell(
      withReuseIdentifier: FavorAnniversaryCell.reuseIdentifier,
      for: indexPath
    ) as? FavorAnniversaryCell else { return UICollectionViewCell() }
    cell.reactor = reactor
    return cell
  case .friend(let reactor):
    guard let cell = collectionView.dequeueReusableCell(
      withReuseIdentifier: FriendCell.reuseIdentifier,
      for: indexPath
    ) as? FriendCell else { return UICollectionViewCell() }
    cell.reactor = reactor
    return cell
  }
}, configureSupplementaryView: { dataSource, collectionView, kind, indexPath in
  guard let header = collectionView.dequeueReusableSupplementaryView(
    ofKind: kind,
    withReuseIdentifier: MyPageSectionHeaderView.reuseIdentifier,
    for: indexPath
  ) as? MyPageSectionHeaderView else { return UICollectionReusableView() }
  let section = dataSource[indexPath.section]
  header.reactor = MyPageSectionHeaderViewReactor(section: section)
  return header
})

적용 후

let dataSource = MyPageDataSource(configureCell: { _, collectionView, indexPath, items in
  switch items {
  case .giftStats(let reactor):
    let cell = collectionView.dequeueReusableCell(for: indexPath) as FavorGiftStatsCell
    cell.reactor = reactor
    return cell
  case .setupProfile(let reactor):
    let cell = collectionView.dequeueReusableCell(for: indexPath) as FavorSetupProfileCell
    cell.reactor = reactor
    return cell
  case .prefers(let reactor):
    let cell = collectionView.dequeueReusableCell(for: indexPath) as FavorPrefersCell
    cell.reactor = reactor
    return cell
  case .anniversary(let reactor):
    let cell = collectionView.dequeueReusableCell(for: indexPath) as FavorAnniversaryCell
    cell.reactor = reactor
    return cell
  case .friend(let reactor):
    let cell = collectionView.dequeueReusableCell(for: indexPath) as FriendCell
    cell.reactor = reactor
    return cell
  }
}, configureSupplementaryView: { dataSource, collectionView, kind, indexPath in
  let header = collectionView.dequeueReusableSupplementaryView(
    ofKind: kind,
    for: indexPath
  ) as MyPageSectionHeaderView
  let section = dataSource[indexPath.section]
  header.reactor = MyPageSectionHeaderViewReactor(section: section)
  return header
})

나도 이거 고민하고 있었는데 잘 됐다!
적용하는게 훨씬 좋을 것 같아 !

오케!

브랜치 하나 파서
내가 만들었던 부분에 적용하고 풀리퀘 올릴게!
