Getting Started

To use AMSMB2, add the following dependency to your Package.swift:

dependencies: [
    .package(url: "", .upToNextMinor(from: "3.0.0"))

You can then add the specific product dependency to your target:

dependencies: [
    .product(name: "AMSMB2", package: "AMSMB2"),


Just read inline help to find what each function does. It's straightforward. It's thread safe.

To do listing files in directory and file operations you must use this template:

import AMSMB2

class SMBClient: @unchecked Sendable {
    /// connect to: `smb://guest@XXX.XXX.XX.XX/share`
    let serverURL = URL(string: "smb://XXX.XXX.XX.XX")!
    let credential = URLCredential(user: "guest", password: "", persistence: URLCredential.Persistence.forSession)
    let share = "share"
    lazy private var client = SMB2Manager(url: self.serverURL, credential: self.credential)!
    private func connect() async throws -> SMB2Manager {
        // AMSMB2 can handle queueing connection requests
        try await client.connectShare(name: self.share)
        return self.client
    func listDirectory(path: String) {
        Task {
            do {
                let client = try await connect()
                let files = try await client.contentsOfDirectory(atPath: path)
                for entry in files {
                        "name:", entry[.nameKey] as! String,
                        ", path:", entry[.pathKey] as! String,
                        ", type:", entry[.fileResourceTypeKey] as! URLFileResourceType,
                        ", size:", entry[.fileSizeKey] as! Int64,
                        ", modified:", entry[.contentModificationDateKey] as! Date,
                        ", created:", entry[.creationDateKey] as! Date)
            } catch {
    func moveItem(path: String, to toPath: String) {
        Task {
            do {
                let client = try await self.connect()
                try await client.moveItem(atPath: path, toPath: toPath)
                print("\(path) moved successfully.")
                // Disconnecting is optional, it will be called eventually
                // when `AMSMB2` object is freed.
                // You may call it explicitly to detect errors.
                try await client.disconnectShare()
            } catch {


While source code shipped with project is MIT licensed, but it has static link to libsmb2 which is LGPL v2.1, consequently the whole project becomes LGPL v2.1.

You must link this library dynamically to your app if you intend to distribute your app on App Store.
