Apple will delist App Store apps that haven’t been updated recently
Apple plans to imminently remove games and apps on the App Store that have not been recently updated if developers don't submit an update for approval within 30 days. This news comes from screenshots and claims shared by various app developers and reporting by The Verge.
It's not clear whether this rule means users must keep the app installed on their devices to continue to access it or if it will be available from the previously downloaded apps list even if the app is no longer listed on the store.
It's also unclear whether this is a newly enforced rule or just a particularly big wave of notifications about it. Apple announced its intentions to do something similar in 2016, but developers have no way of knowing how often the rule is enforced. And while that initial announcement seemed more focused on apps that lacked support for new iOS and iPhone or iPad features, some of the developers who received this recent email claim their apps work perfectly on modern hardware and the current version of iOS.
