iOS 11 is not supporting 32-bit Applications
The new version of the Apple’s mobile operating system iOS 11 officially stops supporting 32-bit applications. This was confirm from the first developer beta released by the company yesterday.
When trying to open a 32-bit iOS 11 application, the user receives a message that says to work with the new operating system the app needs to be updated. Old, already purchased 32-bit applications can no longer be installed through the App Store.
Apple started to notify the developers a few months ago. In October last year, the company warned consumers that old apps could “slow the iPhone”. In January of this year, the iOS 10.3 beta show a message that “this app will not work with future versions of iOS.”
For iOS 11 users who worried that their favorite apps may no longer run, you can check which apps do not support 64-bit architectures via Settings on iOS 10 or iOS 11.
Simply go to General -> About -> Applications. If you have 32-bit apps installed, you will be able to tap on Applications and see a list of your software. While on iOS 10 these apps still launch, on iOS 11 you can only hope that the developer will continue to maintain the application and releases an update.
And if you wonder if your device is compatible with iOS 11 here is the complete list of supported devices. Post from: GizBrain
