The integration of ChatGPT with Siri and Writing Tools in iOS 18 is expected to enhance user experience in several ways. With ChatGPT integrated into Siri, users will be able to ask Siri complex questions that may require broader world knowledge or specialized domain expertise. This partnership aligns with OpenAI's mission to make advanced AI accessible to everyone.
Moreover, ChatGPT will also be integrated into system-wide writing tools. With the new Compose feature, users can generate content, such as custom bedtime stories, and utilize ChatGPT’s image capabilities to create illustrations in various styles. Users can access ChatGPT for free without creating an account, while subscribers can connect their accounts for additional features. Apple emphasizes user control over when ChatGPT is used and requires permission before sharing any information.
In addition to this, Apple Intelligence will enhance the company's Siri digital assistant to make it more natural and contextually relevant6. It will feature a new design, deep integration with the system experience, and support for both voice and text interactions6. Users will be able to rely on Siri for a broad range of tasks, including managing personal context and taking actions across apps.
Overall, the integration of ChatGPT with Siri and Writing Tools aims to provide users with a more personalized and efficient experience, drawing on the user's personal context to provide more relevant and helpful intelligence, while safeguarding privacy at every step.

The new iOS 18 feature aims to prevent children from making unsupervised purchases on apps like Amazon by allowing users to lock and hide apps on their iPhones' home screen3. This feature enables parents to restrict access to certain apps, requiring a Face ID, Touch ID, or a password to open the locked apps. By locking apps such as Amazon, parents can prevent their children from accessing the app and making unauthorized purchases without their consent.

iOS 18 will introduce several features to enhance app privacy and user control on iPhones. Some of these features include:
Lock and Hide Apps: Users will be able to lock and hide apps on their iPhones' home screen2. This feature is meant to help people keep their banking apps private and prevent kids from accessing certain apps like Amazon. When an app is locked or hidden, content like messages or emails inside the app is hidden from search, notifications, and other places across the system.
Customizable Home Screen: Users will be able to customize their home screen for the iPhone, which allows them to rearrange icons as they want them to appear, unlike the current grid system. Users can also change the color of their apps' icons to their liking.
Apple Intelligence: This new AI-powered system responds to prompts, creates new text and images, and solves problems for its users. Apple Intelligence will feature a Rewrite tool that users can use to help them reword tricky messages. The tool can be adjusted to sound friendly, professional, or concise depending on the users' message.
Share Only Specific Contacts: iOS 18 will allow users to share only specific contacts with an app1. This will give users more control over their data and privacy.
RCS Support: Apple is planning to add RCS support to iPhones sometime in 2024. RCS, or Rich Communication Services, is the successor to SMS and MMS. It will bring a number of iMessage-style features to texts between iPhone and Android users. It will also give users the ability to share their location with other people inside text threads.
New Privacy Features: iOS 18 introduces new privacy features designed to empower users. These include enhancements to Safari Private Browsing, Communication Safety, and Lockdown Mode, as well as app privacy improvements3.
Password App: iOS 18 will include a dedicated Passwords app for the first time. This new app will make it easier for users to log in to websites and software, following years of Apple displaying passwords through the Settings app instead of a dedicated app.
Control Center Redesign: The Control Center has been completely redesigned to provide easier and faster access to your favorite controls. There are also new levels of customization and flexibility. The new design gives users groups of their most utilized controls, like media playback, Home, connectivity, and more. Users can easily swipe between each one.
These features aim to give users more control over their apps and data, providing a more personalized and secure experience.
