The Import from iPhone or iPad command in the File menu uses Continuity Camera to allow direct importing from your iOS device into EagleFiler:
You can also import from your iPhone to create attachments within a rich text file (instead of separate files, as above). To do this, Control-click within the rich text file in the record viewer and choose Insert from iPhone or iPad.
Continuity Camera requires an iPhone with iOS 12 or later and a Mac with macOS 10.14 or later, amongst other requirements.
