Apple is phasing out 32-bit applications and will be finished this fall. Apple will stop supporting 32-bit apps after IOS 11 is released, according to Steven Troughton-smith, a well-known developer. This means that all 32-bit apps in the App Store will not function properly.
Of course, for developers and users, Apple's decision was not too surprising. Starting with IOS 10.3, when a user opens a 32-bit app, Apple has started to remind users that the app needs to be upgraded or it may not run in the future IOS version.
In September 2013, Apple released the iphone 5s, the first iphone with a 64-bit processor, and the iphone started to support 64-bit applications. Since February 2015, Apple has asked developers to submit 64 new apps and app upgrades.
In IOS 9, Apple is ready to retire 32-bit apps, just to remind users that a 32-bit app could cause the device to run slowly. At the same time, Smith also mentioned that for the future A-series processors will also fully remove 32-bit support, this is to increase the chip free space. Last September, Apple announced a big cleanup of the app store, removing problematic and abandoned apps that were removed from the app store in 50,000.
IOS 11 confirms that 32-bit apps will be stopped completely
