does xcode become better?

Yes, Xcode has become better with the release of Xcode 16. It introduces several enhancements aimed at improving the development experience:

1. Generative Models: Xcode 16 incorporates generative models to enhance tools like code completion. This new engine predicts the code you need, using a model specifically trained for Swift and Apple SDKs, and runs locally on your Mac for privacy and speed.

2. Swiftassist: A new feature called Swiftassist acts as a coding companion, helping with tasks like experimenting with new APIs and answering coding questions. It leverages a powerful model running in the cloud to transform ideas into code using natural language.

3. Previews and Builds: Xcode Previews now use a dynamic linking architecture, improving workflow by avoiding project rebuilds when switching between previews and builds. Additionally, explicit modules improve build parallelism and diagnostics.

4. Debugging and Performance: New features like a single view of backtraces and a flame graph in Instruments provide deeper insights into app performance.

5. Localization and More: Enhancements to localization catalogs make it easier to bring apps to a global audience.
