This means that owners of iPhones and iPads that have relatively small capacities of 8GB and 16GB will no longer have to scour their devices to find apps and files to delete to make room for the updates.
Instead, when a user of iOS 9 wants to download and install a system update and doesn't have enough room, a message will appear telling them they have insufficient space for the download, and if they click "Allow App Deletion", iOS 9 will delete apps to free up some storage.
Although this sounds a bit brutal, the update files are only needed temporarily, so once they've been used iOS 9 will delete them. The new feature will then redownload and install the apps that were deleted.
Hopefully any user data that was associated with the apps will either be kept or reinstalled as well, so it should feel like you're carrying on where you left off without too much disruption.
However just because the feature is in an early version of iOS 9, it doesn't necessarily mean that it will make it to the final release later this year, but if it means we can download updates despite a lack of storage space – and not lose any of our files in the process – then hopefully this feature will make the cut.
