I use the UICollectionViewDropDelegate to get the dropped video URL:
public func collectionView(_ collectionView: UICollectionView, performDropWith coordinator: any UICollectionViewDropCoordinator) {
let videoSaver = VideoSaver()
for item in coordinator.items {
// Check if the dropped item is a URL (for videos)
if item.dragItem.itemProvider.hasItemConformingToTypeIdentifier(AVFileType.mov.rawValue) {
item.dragItem.itemProvider.loadFileRepresentation(forTypeIdentifier: AVFileType.mov.rawValue) { (videoURL, error) in
if let droppedVideoURL = videoURL as? URL {
videoSaver.writeToPhotoAlbum(droppedVideoURL)
}
}
}
}
Here's my VideoSaver:
final class VideoSaver: NSObject {
func writeToPhotoAlbum(_ videoPath: URL) {
// `isCompatible` is `true` when I test on my iPhone, but is `false` on the iPad Sim. 🙈
let isCompatible = UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(videoPath.absoluteString)
PHPhotoLibrary.shared().performChanges({
PHAssetChangeRequest.creationRequestForAssetFromVideo(atFileURL: videoPath)
}) { saved, error in
// This is the error:
// (Error?) domain: "PHPhotosErrorDomain" - code: 18446744073709551615 {
// _userInfo = 0x0000000000000000
// }
if saved {
print("SAVED!")
}
}
}
On the iPad Simulator I additionally get this error from calling: UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(videoPath.absoluteString). I do NOT get this error on my real iPhone:
