Apple announced iOS 8 at the keynote event of its annual Worldwide Developers Conference today



From MacRumors:

iOS 8 gets revamped notification features, an upgrade to the keyboard's auto-correct functionality, and the rumored health tracking feature and companion app, called HealthKit. Interactive notification lets users pull down notifications and interact with them to respond to text messages or other actions without leaving the current open app, or complete actions from notifications shown on the lock screen. A new feature in the iOS keyboard, called QuickType, adds predictive typing suggestions that adapt to the current context.
