Hello Ekke,
It looks like the Asset Library Framework has been deprecated as of iOS 9:
https://developer.apple.com/documentation/photos/phasset?language=objc
<https://developer.apple.com/documentation/photos/phasset?language=objc>
The new way to access the assets is through the Photos framework. The above
link contains links to the relevant classes. The Photos framework is feature
rich and allows you to access images separate from their adjustment data or
with the adjustments applied.
The solution involves working with Objective-C++, but using this API is
probably unavoidable given that Apple has moved away from managing images as
files on a local file system.
I hope this is of help to you,
Jeffrey
