1. Synchronization to obtain PHAsset will fail
PHPicker's assetIdentifier needs to be loaded asynchronously with NSItemProvider to obtain valid resources. Directly synchronously reading the result. assetIdentifier will mostly result in nil.
2. Logical errors in maintaining the order of selection
The results array returned by PHPicker itself does not guarantee the selection order, and the order needs to be recorded through other means.
potential issues
3. Lack of PHPhotoLibrary permission check
4. Improper use of PHFetchOptions
Current nil may contain deleted or invalid resources
5. Memory management issues
When dealing with a large number of images, assetMap and assets may occupy too much memory
