The next upgrade of Apple's mobile operating system, iOS 12.2, will come with an annoying surprise for VR and AR developers. It reportedly will block Web access to the accelerometer and gyroscope in Apple mobile devices by default. That means users will have to grant permission to any Web apps or sites that need those components to function, including those with virtual reality and augmented reality components. Apple's move is designed to protect the privacy of its customers by giving them control over who has access to their location data.
