I'm not sure how you are getting the images from a PHAsset, but officially the only way to get the underlying data of PHAsset is through the PHImageManager (recommended) or PHAssetResourceManager.

Using PHAsset or PHAssetResource directly might cause no data to be returned or simply outright crash the app. This is mostly related to iCloud photos and optimized storage, where it could mean that the data isn't actually (accessible) on the phone yet. PHImageManager and PHAssetResourceManager make sure the data is accessible locally before returning.
