FileTree

FileTree is a Swift package that provides a type-safe, declarative way to interact with file system structures.

Features

• Declarative file system structure definition
• Type-safe read and write operations to a directory of that structure
• Render that same struture to a SwiftUI sidebar

Installation

Add the following to your Package.swift file:

dependencies: [
    .package(url: "https://github.com/woodymelling/swift-file-tree", from: "0.1.0")
]

Usage

import FileTree
import UniformTypeIdentifiers

let blogFileTree = FileTree {
    Directory("Blog") {
        File("About", .txt)
        Directory("Posts") {
            File.Many(withExtension: .md)
        }
    }
}

From here, you can:

• Read and write raw data from the file system, allowing you to load Markdown posts, images, configurations, or any binary content.
• Convert raw data into well-defined Swift types to ensure your application logic remains clean and type-safe. Transform text files into strings, decode JSON into models, or parse custom formats into domain-specific types.
• Render file trees in SwiftUI using FileTreeViewable for a visual representation of your project’s structure. Easily inspect directories and files right in your app’s UI.

This approach lets you keep your file system logic expressive yet separated from your business logic. You decide how much detail to expose to the rest of your application, and Swift File Tree takes care of bridging the gap between your on-disk data and in-memory models.

Essentials

• Getting Started Learn the basics of defining a file tree and interacting with it.
