Apple's set to reveal the next generation of the iPhone

It's all over but the waiting for Apple fans, who should get to see two new models of the iPhone unveiled Wednesday in San Francisco. The launch event may provide some clues about Apple's future, as the company deals with a slowing smartphone market. Apple's iPhone sales have dropped over the past year for the first time in the device's history. As a result, the company has poured more effort into services such as Apple Music, its voice assistant, Siri, and smart-home management -- all as a way to make users even more reliant on iPhones, regardless of whether they are the latest model. Consumers may already have seen a glimpse of Apple's future this summer when the company showed off how its mobile operating system, iOS 10, which will allow outside developers to use Siri more deeply for their own apps and create new functions for Apple's Messages service.
