The iOS 18.4 is officially here. Apple released the new update. Alongside macOS 15.4, Apple introduced new features and changes for iPhone, iPad, and Mac on Monday. Before you get too excited, however, know that iOS is still missing an AI-overhauled Siri. This includes on-screen awareness and app integrations, which Apple promised all the way back in June at WWDC. You’ll need to wait until iOS 18.5 (or later) for these features to become available. However, we are excited about Apple’s iOS 18.4 New Features!
Apple has released iOS 18.4, along with several new features for the iPhone. However, the iOS 18.4 update also comes with a warning to update now, as it addresses a substantial list of 62 security vulnerabilities, some of which are considered serious.
Apple doesn’t give much detail about what’s fixed in iOS 18.4, to give people as much time to update their iPhones as possible before attackers can get hold of the details. Among the fixes, the iOS 18.4 upgrade patches several critical bugs in WebKit, the engine that underpins the Safari browser — and the Kernel at the heart of the iPhone operating system
The New Apple’s iOS 18.4 Features
The iOS18 improves writing across the operating system. It also makes Siri much smarter. It allows for multiple forms of content generation, too. A set of Writing Tools are available across all apps for rewriting, polishing, proofreading, and summarizing text. You can change your tone, make your writing more concise, and ensure there are no spelling or grammar errors.
The Image Playground app lets you generate images using prompts or Apple’s suggestions and themes. You can incorporate pictures of your friends and family to make all kinds of fun custom photos in styles. They include Animation, Illustration, or Sketch. Image Playground image generation is built into Messages, Notes, and other apps.
Apple’s iOS 18.4 patches an issue in the iPhone Kernel tracked as tracked as CVE-2025-30432. It could see a malicious app able to attempt passcode entries on a locked device and cause escalating time delays after four failures.
Tracked as CVE-2025-24208, a bug in WebKit could put you at risk from a cross site scripting. This is where an attacker injects malicious scripts into a trusted website. If you inadvertently load a malicious iframe, Apple warns on its support page.
