tauri-plugin-ios-bookmark

iOS security-scoped bookmark plugin for Tauri 2.

This plugin provides a native bridge for opening files from the iOS Files app, creating persistent security-scoped bookmarks, reading bookmarked files later, and forgetting saved bookmarks.

This crate is intended for Tauri 2 mobile apps that target iOS. The Rust crate registers the native plugin, while the guest JavaScript API exposes a small command surface for your frontend.

Features

• pickAndBookmark: presents UIDocumentPickerViewController, reads the file, and returns a bookmark identifier plus file metadata
• readByBookmark: resolves a previously saved bookmark and reads the file again
• forgetBookmark: removes a stored bookmark

Package Layout

• src/: Rust plugin entrypoints and mobile bridge
• ios/: Swift implementation for the iOS native plugin
• guest-js/: TypeScript guest API entrypoint
• permissions/: default Tauri permission definitions

Install

Add the Rust crate to your Tauri app:

cargo add tauri-plugin-ios-bookmark

Install the guest JavaScript API in your frontend package:

npm install tauri-plugin-ios-bookmark-api

The guest package expects @tauri-apps/api from your Tauri application.

Rust Setup

Register the plugin in your Tauri builder:

fn main() {
    tauri::Builder::default()
    .plugin(tauri_plugin_ios_bookmark::init())
    .run(tauri::generate_context!())
    .expect("error while running tauri application");
}

JavaScript Usage

The guest API exposes three commands:

import {
    forgetBookmark,
    pickAndBookmark,
    readByBookmark,
} from 'tauri-plugin-ios-bookmark-api'

const picked = await pickAndBookmark()
const targetedPick = await pickAndBookmark({
    targetPath: '/docs/related.md',
})

console.log(picked.bookmarkId)
console.log(picked.fileName)
console.log(picked.filePath)
console.log(picked.content)

console.log(targetedPick.bookmarkId)

const reread = await readByBookmark(picked.bookmarkId)
console.log(reread.fileName)
console.log(reread.content)

await forgetBookmark(picked.bookmarkId)

pickAndBookmark() returns:

type PickBookmarkRequest = {
    targetPath?: string
    suggestedFileName?: string
}

type PickResult = {
    bookmarkId: string
    fileName: string
    filePath?: string
    content: string
}

When targetPath is supplied, the plugin performs exact-file validation after the user picks a file. If the selected file does not match the requested target, the command rejects instead of creating a bookmark for the wrong file.

readByBookmark() returns:

type ReadResult = {
    fileName: string
    content: string
}

Permissions

The default permission set enables all plugin commands.

Available permissions are documented in permissions/autogenerated/reference.md and include:

• ios-bookmark:allow-pick-and-bookmark
• ios-bookmark:allow-read-by-bookmark
• ios-bookmark:allow-forget-bookmark

Platform Notes

• This plugin is iOS-only.
• The file picker is backed by UIDocumentPickerViewController.
• If targetPath is provided, the plugin uses it as best-effort picker context and enforces exact-file validation after selection.
• Bookmarks are intended for persistent access to user-selected files.
• On unsupported platforms, initialization returns an unsupported error path.
