v0.1.0

Initial release.

Added

• FTPServer: a read-only FTP server for iOS and macOS, built on Network.framework with no dependencies
• File providers: FTPDirectoryProvider (a directory and its subdirectories), FTPSingleFileProvider (one file) and the FTPFileProvider protocol for custom sources
• Passive mode (PASV, EPSV), resume (REST), SIZE and MDTM
• Downloads streamed in chunks
• Username and password or anonymous login
• async start that reports errors such as a port already in use
• Server events as an AsyncStream, a Combine publisher or a delegate, plus a log handler
• Opt-in workarounds for older and embedded FTP clients
• DocC documentation and a SwiftUI example app

Requirements

• iOS 15 or macOS 12
• Swift 6 (Xcode 16 or later)

Known limitations

• Read-only: uploads, deletes and renames are rejected with 550
• Clients must use passive mode
• No TLS, so credentials and files are sent unencrypted
• On iOS, stop the server when the app goes to the background and start it again when the app becomes active
