Owners of iPhones and iPads who install the latest version of Apple’s mobile operating system will find that some older apps will stop working.

The move will generally affect apps that have not been updated in the past two years.

Although many will have been abandoned by their developers, owners will still use some of them frequently.

It is a consequence of iOS 11 being restricted to running apps written in what is known as 64-bit code.

The number signifies how much data a processor can handle at once – the larger the figure, the faster a computer can potentially operate.
