Xcode 16 introduces several AI features that enhance the development experience:

  1. Code Completion: Xcode 16 features an innovative new engine for code completion that uses generative models. This engine predicts the code you need by using your project symbols to customize suggestions. It runs locally on your Mac, ensuring your code remains private and providing fast results, even offline. This is powered by a model specifically trained for Swift and Apple SDKs.

  2. Swiftassist: A new tool called Swiftassist acts as a companion for coding tasks. It can answer coding questions, help with experimenting with new APIs, and transform ideas into code using natural language. Swiftassist runs in the cloud and is designed with privacy in mind, ensuring that your code is not stored on the server or used for training machine learning models.

  3. Enhanced Productivity Features: Xcode 16 also includes features like a single view of backtraces, a flame graph for profiling data, and enhancements to localization catalogs, all aimed at improving productivity and app quality.
