Photo Asset Iteration

Question

I'm messing with some photo assets and I am trying to go through my camera roll and print out all the assets from every single photo. I know it would need to be a for loop but just not entirely sure how to write it

guard let selectedIndexPath = collectionView.indexPathsForSelectedItems?.first else { return nil }

let sectionType = sections[selectedIndexPath.section]
let item = selectedIndexPath.item
let assets: PHFetchResult<PHAsset>
let title: String

switch sectionType {
case .all:
  assets = allPhotos
  title = AlbumCollectionSectionType.all.description

case .smartAlbums, .userCollections:
  let album =
    sectionType == .smartAlbums ? smartAlbums[item] : userCollections[item]
  assets = PHAsset.fetchAssets(in: album, options: nil)
  title = album.localizedTitle ?? ""
}
print("\(assets)")
print("\(assets.object(at: 0))")
return PhotosCollectionViewController(assets: assets, title: title, coder: coder)'

Answer 1

You can use .enumerateObjects on assets to loop through them:

assets.enumerateObjects { (asset, count, stop) in
    //asset is the PHAsset
}
