The iOS 9 update will be able to delete and then re-download apps on user devices during installation to make it easier to load the software.
Apple has worked hard to make the iOS 9 update as small as possible, revealing during the WWDC keynote when it unveiled the OS that it has managed to make it just 1.3GB, down from the 4.58GB that iOS 8 required.
The size of the update for iOS 8 made it hard for a lot of people to install the software, as it required removing content and apps from their device, which many were reluctant or unwilling to do.
Developers looking at the iOS 9 beta 2 update have now discovered that Apple has introduced a feature that will delete apps while the update is installed, and reinstall them once the update is complete.
"Holy **** guys this is awesome. It will ask you if you want it to delete apps and then have it reinstall them later. Thats SUPER mega awesome iOS 9 feature," wrote user The Doctor11.
An iOS developer also pointed out the feature on Twitter:

The move should mean that users don't notice anything different on their phone once the update is installed, as it will ensure that apps are returned to the homescreen once the move to iOS 9 is complete.
The iOS 9 beta 2 update includes a few other tweaks, such as renaming the Apple Watch app as simply Watch, and changing the icons for the keyboard for undoing and redoing actions.
There is no set release date for iOS 9, but it is likely to be sometime around September when the next-generation iPhone models will be unveiled, which will probably be called the iPhone 6S and iPhone 6S Plus.
