I am using EmbeddedSection Controller for showing horizontal scrolling list. I want to have just one selected cell in the horizontal list. (and deselect others when one is selected) I can see there are two approaches:

1. Iterate over SCs and see which are selected
2. Create delegate that forwards selections/deselections.

However, in a discussion of #184, @rnystrom has mentioned that they are trying to bake support into IGListKit. What is the best way to do it now? Is there an example?

Right now we don’t have great first-class support for multi selection. You should be able to use this API as-is already. Have you tried that yet?

FWIW we use the delegation pattern at Instagram which gives us much more control over.
