Apple Reminds Developers of 64-Bit Requirement for Apps in iOS 11

Share:

Developers, Apple wants to remind you apps for iOS 11 and macOS High Sierra must support 64-bit, with the latter starting next year. Announcements made on the Developer News Portal reiterates 32-bit apps won’t work in iOS 11, so “we recommend submitting an update so your users can continue to run your apps on iOS 11, which will be in the hands of hundreds of millions of customers this fall.”

As for the Mac App Store, new apps submitted will require 64-bit support starting in January 2018, while Mac app updates and existing apps need to support 64-bit by June 2018. For developers who distribute apps themselves, Apple says “we highly recommend distributing 64-bit binaries to make sure your users can continue to run your apps on future versions of macOS.” Apple says macOS High Sierra will be the last version of macOS “to support 32-bit apps without compromise.”

Apple already told developers of this requirement at WWDC, but now they’re making sure all developers know about 64-bit requirements. Let’s hope the developers of your favourite 32-bit apps will update their apps so you can keep using them in iOS 11.

    A little scary. Not sure what apps we willnend up losing, but it’s way more important to continue to progress.

  • This could really be annoying for users if developer failed to update their apps.
