App crashes iOS11 when saving photo to album

On iOS 10.3.3 there was no issue with using the option savetophotoalbum. Upon upgrading to iOS 11 that option now causes the app to crash after selecting "use photo" for a freshly captured image.
Other things i've noticed while troubleshooting:
1. The permissions for the camera seem to be different between iOS 10.3.3 and iOS 11. I have not been asked to allow permissions to the photos. Not when taking a photo nor when uploading from the photo library.
2. because of the above, when i look under my app in settings, it only shows permissions for the camera. on iOS 10.3.3 it showed permissions for both camera and photo
