Apple is making a few small tweaks to its App Store Review Guidelines for developers ahead of the release of iOS 10 and macOS Sierra this fall. The changes, which Apple is currently telling registered developers about via e-mail, are meant to cut dead wood out of the App Store and to make it easier for users to find better apps. These are the latest in a series of App Store changes implemented since Apple worldwide marketing SVP Phil Schiller was given the reins back in December of 2015.

The biggest change is that Apple will begin to remove older, outdated apps from the App Store that no longer follow current review guidelines or that haven't been updated to support new APIs or features. Removing old apps will also cut down on the number of apps that haven't been updated for compatibility with newer iOS versions or iDevices.

Apple isn't saying exactly what criteria it will use to remove apps, just that it is "implementing an ongoing process of evaluating apps for these issues, notifying their developers, and removing problematic and abandoned apps." People who have already downloaded these apps will still be able to download them, developers will be given 30 days to issue an update before their app is removed, and if their apps are removed they will still be associated with that developer's account and other developers won't be able to use the names for other apps.

The other update is related to app names—apps submitted to the App Store will now have their names capped at 50 characters. This is meant to cut down on the number of apps that give themselves long names with multiple keywords intended to improve search ranking.

Sierra and iOS 10 are both likely to be released later this month. We'll find out the specific dates at Apple's product event on September 7, the same day that these App Store guidelines take effect. Below, see some of Apple's official messaging regarding the changes.
