It may increase read-write speeds on iOS and macOS, as well as space on iOS devices, due to the way APFS calculates available data. The APFS code, like the HFS+ code, uses the TRIM command for better space management and performance. It uses 64-bit inode numbers, and allows for more secure storage. The file system can be used on devices with relatively small or large amounts of storage. The specification for software encryption was documented later. Īpple released a partial specification for APFS in September 2018 which supported read-only access to Apple File Systems on unencrypted, non-Fusion storage devices. APFS was released for 64-bit iOS devices on March 27, 2017, with the release of iOS 10.3, and for macOS devices on September 25, 2017, with the release of macOS 10.13. History Īpple File System was announced at Apple's developers’ conference (WWDC) in June 2016 as a replacement for HFS+, which had been in use since 1998. APFS is optimized for solid-state drive storage and supports encryption, snapshots, and increased data integrity, among other capabilities.
