How save iphone photos on endless os

How is it possible to save photos from iphone?
Itunes is not in the app-center
the app shotwell is automatically opened when connecting the iphone, but does not find any photos or videos.
What can i do? If this is not possible Endless OS is not useful and will not gain a wide number of new users.
do i have to install windows?
