Core Motion
Core Motion is an Apple framework that provides access to motion and environmental data from iOS, iPadOS, watchOS, and macOS devices. It processes raw sensor data from accelerometers, gyroscopes, magnetometers, and barometers to deliver processed motion events like device orientation, rotation rate, and user activity. Developers use it to create apps that respond to physical movement, such as fitness trackers, games, and augmented reality experiences.
Developers should learn Core Motion when building apps that require motion-based interactions, such as fitness apps that track steps or workouts, games that use tilt controls, or AR apps that align virtual objects with the real world. It's essential for health and fitness applications on Apple platforms, as it provides access to activity data like walking, running, or cycling, and enables features like fall detection in watchOS apps.
