I can't sync my photos to my iDevices anymore.

Question

I have gone round and round with the Geniuses at the Glendale store didn't help (they don't understand what's happening either), and getting help on some of the Discussion Groups can be limited at best.
The problem: I cannot sync my Aperture galleries since the switch to Mavericks/IOS 7, and the problem is a little more complicated than you might think.  This isn't rocket science.  This is something I've been able to do for years prior to the upgrade.
How did I attack the problem?  Well, the first thing I did was take care of my the Aperture Library.  I was having a hard time even repairing the Library wihtout it quitting midway through the procedure.  I repaired the external harddrive I keep the Library on by repartitioning it, and giving it a new...what's the word? Core?  After that rebuilding the Aperture Library was no problem.
Two, I rebuilt my iPad from scratch.  Blew out all the software, reinstalled everything.  (I was about to do the same for my iPhone).
Now, the first thing I did with the clean iPad was install on two Photo galleries.  But instead of selecting the Smart Galleries I've had been syncing for years, I used the regular galleies for my photos.
Thing worked like a charm.
Then once I got that going, I decided to switch back over to the Smart Galleries.
And then, all **** broke loose.  My Photos wouldn't just not sync.  The photo tab on iTunes would permanently hang.  Room is taken up on the iPad showing photos on the drive, but no photos are there.  Overall iTunes will hang and crash.
It's the Smart Galleries.  iTunes/Mavericks will NOT sync Smart Galleries to whatever iDevices for whatever reason.
Then it gets weirder.
I use multiple Aperture Libraries.  Look at one for one kind of work.  Look at another for my own stuff.  I only sync my iPad with my stuff.  I just look at the other gallery.  Just so we're clear, I'm not syncing with two Libraries.  I just sync one...and do it consistently.
But just viewing another Library, will break whatever sync set up I have between the iPad and Aperture.  This was never a problem before.  Aperture is built to handle more than one Library.  Flipping back and forth shouldn't be any big deal.  But it is.  Again, if I view a second Aperture Library, and then sync my iPad with iTunes.  All my photos disappear off that iPad.  Consistently.
I can't say they're erased, but my ability to view them on my iPad is taken away.
I have a Library of some 11,000 pictures.  My iPad has traditionally been able to handle that no problem.  You work with as many photos as I do, having seperate libraries is a necessity.  Being able to swap among various Libraries was a plus for working with Aperture.  It's why I bought it.  But now I have an Apple Product (Aperture), being damaged by another Apple product (Mavericks), and I'd kinda like to hear what Apple is going to do about this, because being able to replicate this problem...is a bug.  And to do what I need to do, show off photos, work with Libraries, I kinda need this bug to go away.

Answer 1

it had to do with Maverick/Aperture not supporting the same date formats as before in Smart Albums when I upgraded.
Smart albums based on dates have always been problematic, if you use smart settings that require a date string to be entered. How the date string will be interpreted, will depend on your settings in the System Preferences > Language&Text > Advanced > Dates formats and the "Region".
It is much safer to use "Calendar" rules in Aperture instead of "Date" rules with date-strings. Calendar rules will remain valid, if the region settings are changed in the System preferences.
