iOS 11 Release Could Mean Some Apps Won't Work

When iOS 11 is released later this year, nearly 200,000 apps will no longer work on updated phones, according toSensor Tower.
Developers working in a beta version of iOS 10.3 found popups on old apps warning that apps designed for 32-bit processors would not work on future versions of iOS, usually those notifications just warned that the app could slow down the phone.
