Not to add another topic with these guys, but I think the decision on who's playing SS has to come pretty soon, like in a month or two.
Here's how I see this thing unfolding, if Swanson keeps playing well at AA, in a month or two he's going to get called up to join Albies in the infield; at that point the Braves should make the decision on who's going to SS and who's staying at 2B.
Then you let the two of them play together and develop that familiarity at AAA for a month or two before potentially calling one or both of them up around September.
I'm guessing the Braves already know which one is going to be the SS.
