Apple sent out an email to registered iOS developers on Wednesday, reminding them that beginning February 1, 2015, new apps submitted to the App Store will have to feature 64-bit support and be built on the iOS 8 software development kit. 

Furthermore, Apple says that beginning June 1, 2015, new app updates submitted to the App Store will need to include 64-bit support and be built with the iOS 8 SDK.

Apple sent out the email just in time for the App Store review team to leave for holiday break December 22 to December 29.

Apple brought 64-bit support to the iPhone 5s in 2013, and of course extended it to the iPad, iPhone 6, and iPhone 6 Plus. The iPhone 5c is the only current device in Apple’s lineup to not see the performance benefit of a 64-bit chip architecture.

Update: A previous version of this article incorrectly stated apps would be suspended if not updated with 64-bit support.

  • So how will it work for the 32bit devices?
    and how much pefromance will it gain on 64bit devices? Doesnt a 64bit device need 4GB or ram ?

    • Shawn

      Being able to use more ram is only one of the benefits of 64 bit. Better memory mapping. Better cpu calls. List goes on.

    • jp2002

      There would be two binaries for each app 32 and 64, all within one package. The appropriate binary is selected on the time of invocation of the app.

  • Arjan Vlek

    False. In the picture they say that you only need to include 64-bit support if you want to release an update, never is said that existing apps will be suspended from the App Store.

    • Buzz { Light:Year; }

      They are requirements. If they don’t meet it then they are gone..

      • Me

        They will deny the update if it’s not 64 bit compatible… not ” they are gone “

  • Shawn

    It very clearly says that app updates must now be 64 bit as well. Nowhere did it say they would be suspended if they didn’t update it.

    • Buzz { Light:Year; }

      They are requirements. If they don’t meet it then they are gone.

      • Shawn

        It is a requirement for new apps now and updates later. If the app isn’t updated they aren’t going to simply take it down. They have never done that. You can still find nonretina apps and apps not scaled for iPhone 5 and up.

        The email is plain and simple. All future updates must be 64 bit. Nowhere in the email does it mention anything about suspension.

      • Buzz { Light:Year; }

        Your right i just read the article and that’s what they said.

    • Jake Smith

      Fixed. Sorry

  • Osama Muhammed

    what if the developer is inactive, or the app is dead ( no updates ) but more likely to save time and lives in the future

    • A man

      If the app is dead it won’t work on newer is because of compatibility

      • Osama Muhammed

        not very dead, give it a year old, or ios 6 >

  • Lui

    It would be better for them to learn how to fix iOS 8 bugs. I really hope they are not planning to introduce iOS9.

  • Buzz { Light:Year; }

    And 5

  • Buzz { Light:Year; }

    So apps being built with iOS 8 sdk, will that force people to be on iOS 8 just to install the app?

    • jp2002

      Nope. You need to provide a 64bit version too along with the existing 32 bit binary if I’m right.

  • Jake Smith

    Have updated the article. Sorry for the mistake everyone.

  • Linton Findlay

    I wish apps that aren’t even supporting iPhone 5 screen would be pulled, it should be a standard now. It’s frustrating downloading a good app but it looks rubbish because it’s not optimised for ios7

  • Матт Реякіпѕ

    I’m glad Apple’s doing this but a lot of developers will just leave their current apps for dead and won’t release new apps until the next iPhones come out. A way Apple can motivate developers more is pulling paid apps and disabling iAPs on apps/games that haven’t been updated for a year. This way developers can’t collect money on apps and games they refuse to update.

      so iphone 5g not support
