SMBClient

Swift SMB client library and iOS/macOS file browser applications. This library provides a high-level interface to the SMB protocol and allows you to access files on remote SMB servers. Written in Swift, no dependencies on external libraries.

Usage

SMBClient class hides the low-layer SMB protocol and provides a higher-layer interface suitable for common use cases. The following example demonstrates how to list files in a share drive on a remote SMB server.

import SMBClient

let client = SMBClient(host: "198.51.100.50")

try await client.login(username: "alice", password: "secret")
try await client.connectShare("Public")

let files = try await client.listDirectory("")
print(files.map { $0.fileName })

try await client.disconnectShare()
try await client.logoff()

If you want to use the low-layer SMB protocol directly, you can use the Session class. Session class provides a set of functions that correspond to SMB messages. You can get more fine-grained control over the SMB protocol.

import SMBClient

let session = Session(host: "198.51.100.50")

try await session.connect()
try await session.negotiate()

try await session.sessionSetup(username: "alice", password: "secret")
try await session.treeConnect(path: "Public")

let files = try await session.queryDirectory(path: "", pattern: "*")
print(files.map { $0.fileName })

try await session.treeDisconnect()
try await session.logoff()

Log in to the remote SMB server

let client = SMBClient(host: "198.51.100.50")
try await client.login(username: "alice", password: "secret")

List share drives

let shares = try await client.listShares()
print(shares.map { $0.name })

Connect to a share drive

try await client.connectShare("Public")

List files in a directory

let files = try await client.listDirectory("Documents/Presentations")
print(files.map { $0.fileName })

Download a file

let data = try await client.download(path: "Pictures/IMG_0001.jpg")

Upload a file/directory

try await client.upload(data: data, path: "Documents/Presentations/Keynote.key")

FAQ

How to connedct to macOS file sharing?

To connect to macOS file sharing, you need to enable "Windows File Sharing" in the "Sharing" sytem settings in "File Sharing" section. This will enable NTLM v2 authentication on your macOS.

Compatibility with SMB1 and AFP

This library does not support SMB1 and will not support SMB 1.0 in the near future, this is due to SMB1 and SMB2 are not compatible, with completely different packet structures.

Relatedly, connecting to macOS servers using pre-SMB, Apple Filing Protocol (AFP) is not supported.

OS X 10.9 Mavericks and later supports SMB as the primary file sharing protocol.
