Building Tauri App And Using Objc2 And Objc2_user_notifications To Implement MacOS Notifications. The Notification Permission Requests Failed
Introduction
In this article, we will explore how to build a Tauri app and use objc2 and objc2_user_notifications to implement macOS notifications. We will also discuss the common issue of notification permission requests failing and provide a solution to overcome this problem.
Prerequisites
Before we dive into the implementation, make sure you have the following prerequisites:
- Tauri installed on your system
- objc2 and objc2_user_notifications crates installed
- A basic understanding of Rust programming language
Setting Up the Project
To start, create a new Tauri project using the following command:
tauri new my-app
Navigate to the project directory and open the Cargo.toml file. Add the following dependencies to the [dependencies] section:
[dependencies]
objc2 = "0.3.4"
objc2_user_notifications = "0.3.4"
Implementing macOS Notifications
To implement macOS notifications, we will use the objc2 and objc2_user_notifications crates. First, create a new file called notifications.rs in the src directory. Add the following code to this file:
use objc2::runtime::{Object, Class};
use objc2_user_notifications::{Notification, NotificationRequest};
fn request_notification_permission() {
let notification_request = NotificationRequest::new();
let notification_request_class = Class::get("NotificationRequest").unwrap();
let notification_request_obj = notification_request_class.init().unwrap();
let notification_request_obj = notification_request_obj.init_notification_request_with_title(
"Notification Title".to_string(),
"Notification Message".to_string(),
"Notification Action".to_string(),
)
.unwrap();
let notification_request_obj = notification_request_obj.init_notification_request_with_options(

Q: What is Tauri and why do I need it?
A: Tauri is a framework for building cross-platform desktop applications using web technologies. It allows you to build native-like applications for Windows, macOS, and Linux using a single codebase. You need Tauri if you want to build a desktop application that can run on multiple platforms.
Q: What is objc2 and objc2_user_notifications?
A: objc2 is a Rust library that provides a safe and convenient way to interact with Objective-C code. objc2_user_notifications is a crate that provides a Rust interface to the macOS user notifications API. You need these crates if you want to implement macOS notifications in your Tauri app.
Q: How do I request notification permission in my Tauri app?
A: To request notification permission in your Tauri app, you need to use the objc2_user_notifications crate. You can do this by creating a new instance of the NotificationRequest class and calling the init_notification_request_with_title method to set the title, message, and action of the notification. Then, you can call the init_notification_request_with_options method to set the notification options.
Q: What are the common issues I might face when implementing macOS notifications?
A: Some common issues you might face when implementing macOS notifications include:
- Notification permission requests failing: This can happen if the user has previously denied notification permission or if there is an issue with the notification request.
- Notifications not being displayed: This can happen if there is an issue with the notification request or if the notification is not properly configured.
- Notifications not being delivered: This can happen if there is an issue with the notification request or if the notification is not properly configured.
Q: How do I troubleshoot notification issues in my Tauri app?
A: To troubleshoot notification issues in your Tauri app, you can try the following:
- Check the notification request: Make sure that the notification request is properly configured and that the title, message, and action are set correctly.
- Check the notification options: Make sure that the notification options are set correctly and that the notification is properly configured.
- Check the notification delivery: Make sure that the notification is being delivered correctly and that there are no issues with the notification request.
Q: Can I use other libraries to implement macOS notifications in my Tauri app?
A: Yes, you can use other libraries to implement macOS notifications in your Tauri app. Some popular alternatives include:
- mac-notification-sys: This crate provides a Rust interface to the macOS notification API.
- notification-sys: This crate provides a Rust interface to the macOS notification API.
Q: How do I handle notification clicks in my Tauri app?
A: To handle notification clicks in your Tauri app, you need to use the objc2_user_notifications crate. You can do this by creating a new instance of the Notification class and calling the init method to set the notification options. Then, you can call the add_observer method to add an observer to the notification.
Q: Can I use Tauri to build a desktop application that runs on multiple platforms?
A: Yes, you can use Tauri to build a desktop application that runs on multiple platforms. Tauri allows you to build native-like applications for Windows, macOS, and Linux using a single codebase.
Q: How do I get started with building a Tauri app?
A: To get started with building a Tauri app, you need to:
- Install Tauri: You can install Tauri using the
cargo install tauri command.
- Create a new Tauri project: You can create a new Tauri project using the
tauri new my-app command.
- Build and run the app: You can build and run the app using the
cargo run command.
Q: What are the benefits of using Tauri to build a desktop application?
A: Some benefits of using Tauri to build a desktop application include:
- Cross-platform compatibility: Tauri allows you to build native-like applications for Windows, macOS, and Linux using a single codebase.
- Native-like performance: Tauri applications can run at native-like speeds and can take advantage of native APIs.
- Easy to use: Tauri has a simple and intuitive API that makes it easy to build desktop applications.
Q: Can I use Tauri to build a web application?
A: No, you cannot use Tauri to build a web application. Tauri is designed to build desktop applications, not web applications. If you want to build a web application, you should use a web framework such as React or Angular.
