Apple will officially release iOS 11 later this year. However, it will kill 32-bit support for apps which will render nearly 187,000 apps useless.

According to Sensor Tower, about 187,000 iOS apps could be killed when Apple releases the iOS 11.

This is after iOS developers working with a beta version of iOS 10.3 noticed a warning message. The latest iOS 10.3 beta version already has a pop-up that informs users using old apps that "this app will not work with future versions of iOS". The update could affect as much as 8% of apps housed in the App Store that were built for the 32-bit processor of older-generation iPhones. Especially the apps that are not optimized for Apple's 64-bit A7 processor are introduced with the iPhone 5s.

It's unclear which specific apps are still 32-bit - and it's hard to make a definitive list - but it's none of the everyday apps such as Facebook, Instagram, Maps and Pokémon Go. However, there might be some classics that'll take the hit and be missed. Some reputable apps and mobile games that might disappear include "Ridiculous Fishing," "Peggle Classic," and "Great Lightsaber," Mashable has cited.

Last January, rumors indicated that Apple could finally introduce group FaceTime calling with the iOS 11. Reports coming out of Israel claimed that Apple was already working on the functionality.

Apple may consider implementing the feature in the upcoming OS upgrade, especially given the rising popularity of group video chatting apps. Several concept designers have imagined the feature and how it would work. Lack of group calling is one of the reasons why FaceTime is still not a true rival to Skype.

Apple is expected to release iOS 10.3 before the end of March and the deployment is expected to accelerate the shift from 32-bit to 64-bit. The US technology giant has already revealed its yearly developers' conference will take place in San Jose on June 5, 2017
