If you hadn't noticed, iOS 11 has had more than its fair share of bugs. And that's apparently been worrisome enough to prompt a rethink of how the company approaches iOS 12. Axios sources have said that Apple is pushing some major iOS feature updates into 2019 to focus this year's upgrades on "performance and quality issues." Reportedly, Apple is delaying refreshes of the home screen interface, CarPlay, core apps and photography in favor of quality and responsiveness. There will be significant improvements in 2018, the insiders said -- they'll just focus on less dramatic areas like augmented reality, health and parental controls.
