how do I create both an android and ios app?

To create both an Android and iOS app, you would typically need to use a cross-platform development framework or tool that allows you to write code once and deploy it to both platforms. However, the content provided from WWDC focuses on developing apps for Apple platforms. Here are some key points and sessions that might help you in developing apps for iOS and other Apple platforms:

1. Using Xcode for Multi-Device Projects:

   • Xcode makes it simple to target all Apple devices uniformly while still allowing for customization when needed. This is particularly useful for games, as they typically use a common codebase and share most of their project settings across all destinations. You can set up a multi-device project that targets both macOS and iOS devices. This setup ensures that both macOS and iOS can access the full capabilities of their respective SDKs when necessary.
   • Port advanced games to Apple platforms

2. SwiftUI for Cross-Platform Development:

   • SwiftUI is a powerful tool for building user interfaces across all Apple platforms. Once you have a user interface built using SwiftUI for one platform, you have an excellent start to bringing that UI to any platform. SwiftUI enables code sharing and provides idiomatic look and feel on any Apple platform.
   • SwiftUI essentials

3. Unified Metal Shaders for Games:

   • For game development, unified Metal shaders allow you to compile your shaders once and deploy them to both macOS and iOS. This makes the experience of developing for both platforms straightforward.
   • Port advanced games to Apple platforms

4. Cloud Saves for Seamless Multi-Device Experience:

   • CloudKit helps you enable seamless cloud saves, allowing players to continue their progress across different Apple devices. This is particularly useful for games but can be applied to other types of apps as well.
   • Port advanced games to Apple platforms

5. Native SDKs for Best Performance:

   • Using Apple's native SDKs directly provides the fastest possible performance and the best integration with Apple hardware and software. This is emphasized in the Platforms State of the Union session.

For developing Android apps, you would typically use Android Studio and Kotlin or Java. For cross-platform development, frameworks like Flutter, React Native, or Xamarin can be used to target both iOS and Android from a single codebase. However, these are not covered in the WWDC sessions.
