Hi reallyTomFox,
An import from Mac to iOS can’t be done, as their compile formats are different beasts.
There’s an official response from an L&L team member in this similar thread: [url]https://forum.literatureandlatte.com/t/importing-a-compile-format-from-the-mac/43812/1]
If you’d like to learn more about the iOS compile format, do a search here on “.scomp”.
Or, from within a project on iOS Scriv, press Compile (lower left, next to the Gear box). Click on the Appearance selector. Click Edit. Click +. Click On My iPad. Click ? in the upper right.
That’s a very roundabout way to get to an explanation of Scomp instructions. There may be an easier way, but I don’t know it. 
Best,
Jim
