Apple Says 32-Bit Apps Won't Work with 'Future' Versions of iOS

Starting with the first beta version of iOS 10.3, which was released last week, Apple has tweaked the dialog box when users open older legacy, 32-bit apps.

Starting with iOS 10.1, a dialog box appears when opening a 32-bit app:

This app has not been updated to 64-bit. Using it may affect overall system performance.

But with the latest beta version, that information has been tweaked and now states:

This app will not work with future versions of iOS. The developer of this app needs to update it to improve its compatibility.

More than likely starting with iOS 11, which should be unveiled in June at WWDC, 32-bit apps won’t be functional.

The phasing out 32-bit apps has been on the radar for a while. Starting in February 2015, Apple required that all submitted apps offer 64-bit support. And starting in late 2016, Apple began to remove many older 32-bit apps that were “abandoned or problematic.”

Every iOS device with an A7 chip or later can run 64-bit apps. That means the iPhone 5s and later, the original iPad Air and later, the sixth-generation iPod touch, and the iPad mini 2 and later.
