Why is Apple replacing the HFS + file system?

The Apple file system HFS was introduced in 1985 with the Macintosh system software, then HFS + came out in 1998, which is no longer up to date. There were always updates and restructuring, but modern computing now needs a modern system. Both large amounts of data and current storage media (SSD) play a role here.

Although the Apple systems from iOS and macOS to tvOS and watchOS all currently run with HFS +, there are sometimes serious differences in the details such as source code, encryption and therefore also the development on the part of Apple.

Will APFS be open source?

The Apple File System is not currently open source. However, over time the system could be opened - as some Apple examples show (some have already been published openly): LLVM, Mach Kernel, WebKit, Swift.
