Q: iOS 9/iTunes 12.3 not syncing app through devices

Your welcome

It's not a bug it's designed not to by Apple.

how does iOS 9 run on iPad 2? I have iPad 3 and too scared to update as it already having a hard time running ios8

Exactly if I had known this I would not have updated to iOS9 for that very reason and with that being said why be so underhanded about it to the point that your own customer service representatives were unaware as well. Geez! my phone isn't jail broken I have paid and downloaded all my (526) apps from the "Apple" store so what's up with that? I have a MacBook Pro and 7 other Apple devices in my household on a very slow internet connection 1.3MPS at it's best now would you want to babysit all these updates to these devices or transfer them to and from iTunes. Apple has really ****** me off with this crap and I refuse to go quietly about my business, so as I replace these devices over time you best believe it want be with crapple since all they seem to care about anymore is the price of their stock not their customers who spent hard earned money on a device that was more expensive and need to use these devices everyday. WAY TO GO CRAPPLE! ..... BTW if it's not broke don't fix it!!!

I agree totally Airborne_1 - however the history of itunes updates tends to show that apple does like to 'fix' things that aren't broken!

As for your 'slow' internet speed, you musn't be from Australia- that seems to be a fairly high speed here!

I guess downgrading is the only choice left. It This is whats going to happen. Seriously didnt expect this Apple.

except it’s not a choice.

Atleast Apple is still signing the ios 8.4.1 lets see how long that lasts

I found out this deep in the What's new site, yes, iOS 9 will deliver device specific apps, and for iOS 8 and before, the AppStore will continue delivering universal apps:

https://developer.apple.com/library/ios/documentation/IDEs/Conceptual/AppDistrib utionGuide/AppThinning/AppThinning.html

EDIT:

However take a look at this note, so it should accept delivery through iTunes, and according to one guy before, it works under 9.1 beta:

Note: For iOS apps, sliced apps are supported on the latest iTunes and on devices running iOS 9.0 and later; otherwise, the App Store delivers universal apps to customers

came here to say me too

after reading about it being on purpose

thanks apple, nice if you to make me download apps twice

Sorry guys if I am a little thick.  Does this mean that it is two way transfers that are off, not just one way from iOS device to iTunes but also from iTunes to iOS device as well (if the apps are now variant specific, they need to be updated directly to the device).  If so, does this mean I do not need to religiously keep my iTunes app library uptodate?  Meaning there is no need for for an iTunes library.

But if so, what is it that I am updating to my iTunes library?  If all apps are now device variant specific, then are these apps updated to my library also variant specific (if so, then why not let me sync to my device) or are they general apps for all variants (if so, .....)

I AM confused with all these AppleSpeak.

That is all well and good if you are a developer- which I am not so that page is basically gobbledygook, nor does it specifically state (from what I can interpret on the page) that it will not be possible to manage apps on my iPhone (running 9.1) from iTunes  (12.3). I still do not see the logic- iTunes only lets me install apps specific to the device connected. So really, what was the point of this change?

OK I think I worked it out.

So with iOS 9, apps are distributed in pieces just for your device to save space and bandwidth.

Example: A universal game app that is compatible with iPad and iPhone

So on an iPhone 6 it installs the 64-bit version of the app plus the graphics and assets that fit and work on the iPhone 6 only.

On a iPhone 6 Plus it installs the 64-bit version of the app plus graphics and assets for the large 6 Plus screen.

On an iPhone 4s it installs the 32-bit bit version of the app plus graphics and assets for the smaller 4s screen

On an iPad Air 2 it installs a 64-bit version of the app plus graphics and assets for the full size iPad Air 2 screen.

So when you try to sync back to iTunes, you would only have just a pieces of the application for that one device you synced to send back to your iTunes.

I own both an iPad mini 3 and a iPhone 6 Plus. So if I only synced back the pieces of an app for the iPhone, then it would not work for my iPad or other devices.

Therefore iTunes on your PC or Mac really needs to download all the pieces of the app for all devices from the iTunes store so you can sync any device.

That's the way I understand it. I hope that makes sense.

That doesn't explain why iPad Air (9.1) has not been impacted whereas my iPhone 6 (9.1) has. On the iPad I can seen home screens in iTunes, install and rearrange apps via iTunes but not when the iPhone is connected. Also, wouldn't that only affect apps developed and designed to take advantage of the sparse installation feature?

this is doing my head in

nothing happens
