we are working on HDR images and found this problem, asset.mediaSubtypes.contains(.photoHDR) always return false func picker(_ picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]) { guard !results.isEmpty else {return} let fetchResult = PHAsset.fetchAssets(withLocalIdentifiers: results.map({$0.assetIdentifier!}), options: nil) var selectedAssets:[PHAsset] = [] fetchResult.enumerateObjects { asset, _, _ in selectedAssets.append(asset) } for i in selectedAssets.enumerated() { let asset:PHAsset = i.element print("\(i.offset): ") print(PHAssetMediaSubtype.photoHDR.rawValue) print(asset.mediaSubtypes) print("photoHDR \(PHAssetMediaSubtype.photoHDR.rawValue): \(asset.mediaSubtypes.contains(.photoHDR))") print("photoLive \(PHAssetMediaSubtype.photoLive.rawValue): \(asset.mediaSubtypes.contains(.photoLive))") print("photoPanorama \(PHAssetMediaSubtype.photoPanorama.rawValue): \(asset.mediaSubtypes.contains(.photoPanorama))") print("photoScreenshot \(PHAssetMediaSubtype.photoScreenshot.rawValue): \(asset.mediaSubtypes.contains(.photoScreenshot))") print("videoHighFrameRate \(PHAssetMediaSubtype.videoHighFrameRate.rawValue): \(asset.mediaSubtypes.contains(.videoHighFrameRate))") print("videoScreenRecording \(PHAssetMediaSubtype.videoScreenRecording.rawValue): \(asset.mediaSubtypes.contains(.videoScreenRecording))") } }
