Apple today seeded the fourth beta of an upcoming iOS 10.3 update to developers, one week after seeding the third beta of iOS 10.3 and more than two months after the release of iOS 10.2, the last major update to the iOS 10 operating system.
Registered developers can download the fourth iOS 10.3 beta from the Apple Developer Center or over-the-air with the proper configuration profile installed.
iOS 10.3 is a major update, introducing several new features and changes to the iOS 10 operating system. The biggest new consumer-facing feature is “Find My AirPods,” which is designed to help AirPods owners locate a lost earphone. Find My AirPods records the last known location of when an AirPod was connected to an iOS device via Bluetooth and can play a sound on a lost AirPod.
Apple’s latest update also introduces a new Apple File System (APFS), installed when an iOS device is updated to iOS 10.3. APFS is optimized for flash/SSD storage and includes features like strong encryption.
