I’m speaking about the iOS 11.
When the next iteration of the world’s most popular smartphone operating system from Apple will hit the market, along the side iPhone 8, this fall, many of the older iDevices won’t support it.
I’m speaking about the iPhone 5 and 5C and the iPad 4. The reason is about the architecture. When iPhone 5 was released in 2012, and the 5C in 2013, the core application ran on the 32 bit architecture. Which was quite fine. But moving to A7 processors, Apple finally made the jump into the 64 bit architecture.
Two different worlds will collide. As a result, because the iOS 11 is the most advanced operating system, it seems natural that older devices that dated all way back early 2010s won’t work.
However, good news for the owners of iPhone 5 and 5C and iPad 4, you can still appropriate the goodies of iOS 10 as the OS runs smoothly on these iDevices.
