iOS 18.4 release candidate is out now with multiple improvements and new features

iOS 18.4 is destined to be a big release. The headline feature of iOS 18 is Apple Intelligence, and the various AI features have been rolling out piece by piece. After getting no major new AI features in iOS 18.3, Apple is bringing Apple Intelligence to many more countries in iOS 18.4 as well as a new device—Vision Pro.

However, the anticipated Siri update has to wait. There are several big Siri updates coming, including personal context, app intents, and screen reading, but they’re missing from the first iOS 18.4 beta, and Apple is having such trouble making it work well that it’s not coming until next year.

Despite missing this important feature—promised at WWDC last fall—there are lots of improvements in iOS 18.4.

The iOS 18.4 beta began on February 21 with a developer beta, and the first public beta on February 24. We expect the final release in early April.

Updated March 24: The release candidate of iOS 18.4 is now available. We expect the wide release next week.

What’s new in iOS 18.4

We’ll update this section with the features and changes found in the latest iOS 18.4 beta, as they are found.

It only shows up if you have a Vision Pro associated with the same Apple ID.

Mail categories in iPadOS: With the iPadOS 18.4 release, the iPad version of the Mail app finally gets the categories that have been on the iPhone since iOS 18.2.

Default translation app: In the Default Apps section of Settings, there is now an option to set a default translation app.

iOS 18.4: How to install the developer beta

You’ll need to be registered as an Apple developer. Beginning with iOS 18.4, you don’t need to be in the $99 per year developer program to access the developer beta. A free developer account will do. You can get one via Xcode or the Apple Developer app in iOS. Here’s how to do it via the Apple Developer app:

1. Download the Apple Developer App from the App Store.
2. Open the app.
3. Tap on Account.
4. Sign in using your usual Apple ID.

Registered developers can choose to get the Public Beta instead by selecting iOS Public Beta in the Software Update screen. It may take a little time after registering as a developer for the option to appear in Software Updates.

If you want to be among the first to test iOS 18.4, you can sign up for the public beta test, which should arrive in late February. The process for installing a beta has changed in iOS 16.4. Here’s how the new process works now:

1. Click Sign Up on the Apple Beta page and register with your Apple ID.
2. Log in to the Beta Software Program.
3. Click Enroll your iOS device.
4. Open the Settings app, tap General, then Software Update.
