iOS

Here are some key updates and features related to iOS presented at WWDC 2024:

1. Game Mode in iOS:

   • iOS 18 introduces a new game mode that reduces background activity and Bluetooth latency, improving input and headphone responsiveness. This mode can be automatically enabled for your game, or you can opt into it by adding the GCSupportsGameMode key in your iOS info plist. (Port advanced games to Apple platforms)

2. Unified Metal Shaders:

   • Developers can now compile their shaders once and deploy them to both macOS and iOS, thanks to unified Metal shaders. This simplifies the development process for games across Apple platforms. (Port advanced games to Apple platforms)

3. New Controls API:

   • iOS 18 introduces a new controls API that allows developers to create controls by specifying the type, a symbol, and an app intent. These controls can be added to the control center or assigned to the action button on the iPhone 15 Pro. (Platforms State of the Union)

4. Customizable Home Screen:

   • App icons and widgets on the home screen can now appear light, dark, or with a tint. A tinted version of your app icon will automatically be available to users after they upgrade to iOS 18. (Platforms State of the Union)

5. HDR Improvements:

   • iOS 18 includes a new reference wide tone mapping operator that preserves output quality better than the default one, reducing highlight clipping and maintaining color reproduction. This is used for ISO HDR files across iOS, macOS, tvOS, watchOS, and visionOS. (Use HDR for dynamic image experiences in your app)

6. UIKit Enhancements:

   • The iOS 18 SDK brings new features to UIKit, including improvements to transitions and animations, tab bars, and a new document launch experience. (What’s new in UIKit)
