Cannot reproduce here. Works perfectly in the latest 2.8 beta. Can you try with a newer build?

Marking as incomplete until author has tested with newer build.

I can repro with today's git. Here are the steps

Open provided .blend
Select an empty spot on the viewport
- At this point Circle.002 will still be 'active' but nothing will be 'selected'
Hit tab to go into Edit Mode (this is fine because of active)
Select all verts
Do the smart UV unwrap

This is a combination of the weird active/selected state + the operator's current implementation of only looking at selected

I can confirm that I get this issue too if I follow the steps provided by rboxman.

the bug is present whit the initial cube too. it's very simple to replace:

open blender
the cube is select
whit "A" key select none
enter in edit mode whit tab

select UV Smart Project

I have test it whit Linux and Windows ( linux buid blender-2.80-bf9904ec8018-linux-glibc224-x86_64)

CC @dfelinto, @ideasman42, @mont29: it's not clear to me how to iterate over all objects in the current mode in the Python API.

We have BKE_view_layer_array_from_objects_in_mode_params in C.

Can we add something like this, document it in the release notes and use it to fix this bug?

Not sure who best does this, but this seems to be a big hole in the API so marked as high priority.
