iOS 18 Upgrade

iOS 18 introduces several new features and improvements across various aspects of the operating system. Here are some highlights from the WWDC sessions:

1. Tab and Sidebar Enhancements: iOS 18 introduces a new syntax in SwiftUI for tab views, making it easier to catch common errors at build time. This includes declaring a tab struct with a title, image, and content view. UIKit also has new APIs to better describe app hierarchies to UITabBarController (Elevate your tab and sidebar experience in iPadOS).

2. Device Management: iOS 18 includes updates for device management, such as a special exception for enrolling an MDM on a newly set-up device without causing a security delay for the first 3 hours after enabling stolen device protection (What’s new in device management).

3. Privacy Enhancements: iOS 18 improves transparency and control over access to local networks, Bluetooth, and contacts. It introduces a new flow for apps requesting access to contacts, providing more control over which contacts are shared (What’s new in privacy).

4. UIKit Improvements: There are major updates to tabs and sidebars, support for new fluid transitions, and a redesigned launch experience for document-based apps. UIKit also integrates more closely with SwiftUI (What’s new in UIKit).

5. Customization and Security: iOS 18 allows app icons and widgets to appear in light, dark, or tinted versions, providing a consistent visual experience. It also introduces a new registration API for passkeys, enhancing security (Platforms State of the Union).

These updates reflect Apple's ongoing efforts to enhance user experience, security, and developer capabilities in iOS 18.
