Lightroom CC needs to access the folder structure of the Apple Photos app, Please refer these articles and let us know if they help.
I'd like to test if I could but can not find apps for my iPhone X, or for my iMac, named 'Foto' or 'iPhoto'.
Are those the complete names of apps for Apple devices/computers?
this are the program from Apple to store pictures.
First it called iPhoto and now it is Foto (in Germany). To import Pictures from iPhoto its easy - there is a plug in. But the newer Program called "Foto", you can not import the pictures with al tags, etc.
