iOS 11: Apple reveals the future of the iPhone at WWDC

Apple has revealed iOS 11, the future of the iPhone. The software comes with a range of new features, including changes to Messages and other iOS apps. But it also added a range of "technologies" – new tweaks intended to make the apps run much better. That was in keeping with a focus in Apple on improving the experience of its software, turning up and tweaking things rather than adding a host of new features, something it also did in macOS. The I.F.O. is fuelled by eight electric engines, which is able to push the flying object to an estimated top speed of about 120mph.
