Be sure to think twice before upgrading to iOS 11 when it's released this fall. The new operating system works only as 64-bit architecture and your installed 32-bit apps will no longer function after you upgrade until the apps have also been upgraded to work as 64-bit by their developer. Here's what Apple wrote to app developers.
64-bit Apps on iOS 11
June 28, 2017
As a reminder, new iOS apps and updates submitted to the App Store must support 64-bit. Support for 32-bit apps is not available in iOS 11 and all 32-bit apps previously installed on a user’s device will not launch. If you haven’t updated your app on the App Store to support 64-bit, 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.
