Delta update for 3rd party applications

[raghugs]

Hello everyone

Hope you remember that Apple enabled delta updates for 3rd party applications in iOS 6.
But have anybody noticed that it has been disabled in iOS 7x and have not been enabled even in latest version of iOS 8x.
Is it just for me ?

How do you verify if it has been disabled say vs the developer just not using the feature?

According to this Apple Dev Q&A Doc, it has been offered (and still is) since iOS 6. Developers have to choose to implement it, though: https://developer.apple.com/library/ios/qa/qa1779/_index.html

If so, then most developers are not showing interest in implementing it.
Unlike iOS, it is widely being used in Android Platform.

A high percentage of updates are delta. There is no way apps 100+meg in size are downloading to my devices and installing in seconds

Actually I can't agree with you on that.
Facebook, Twitter, viber, eBay and several other prominent applications definitely didn't push Delta updates to me.

A good majority of the app updates are delta updates. When you go to update an app, the App Store is showing the size of the full app, not the update. Real Racing 3 is a 1.9GB file but the updates are typically no more than 45-50MB. That is why you can install these large app updates via cellular because it is indeed less than 100MB.

All the Facebook updates are delta.
