In an effort to push developers to update their iOS apps and make them 64-bit compatible, Apple is bringing back the warning message against 32-bit apps that first appeared during the beta testing period for iOS 10. 

According to MacRumors, Apple has reinstated the alert message via the iOS 10.1 update. As of late, the warning appears in the iOS 10.1 beta that is only available to developers and public beta testers. 

It’s clear that Apple is targeting developers who are reluctant to update their apps to 64-bit in the warning message that says, “The developer of this app needs to update it to improve its compatibility.” The notification appears when the user has clicked on an app that is still running on 32-bit, which could apparently slow down the iOS device.

In early September, Apple sent out notifications to developers that there would be drastic changes on the App Store upon the public unveiling of the iPhone 7, iPhone 7 Plus and iOS 10 on Sept. 7. At the time, Apple wrote that “quality is extremely important,” so it is deleting problematic and abandoned apps after 30 days of non-compliance to the request that they should update their apps. 

Following the release of the iPhone 5s, Apple requested developers to submit 64-bit apps to make use of the 64-bit processor of the handset. In February of last year, Apple made it official that 64-bit support should henceforth be mandatory. Now that it’s already been more than a year since the 64-bit support was made mandatory, Apple is applying stricter policies onto developers who still have not updated their iOS apps.

Early this week, Apple rolled out the second iOS 10.1 beta to developers and beta testers. BGR reported Wednesday that the new beta software comes with refinements and bug fixes on top of the highly anticipated Portrait mode that would turn the dual-lens camera of the iPhone 7 Plus into a smartphone-based rival of high quality DSLR cameras. 

With the release of iOS 10.1 fast approaching, it’s just a matter of time until developers are once again reminded of their duty to update their outdated apps. The warning message may have not made it into the final iOS 10 version, but it is now confirmed to notify users which apps to stay away from when iOS 10.1 is officially released to the public.
