xcode | Ask WWDC

Xcode was a significant focus at WWDC 2024, with several sessions highlighting its new features and improvements. Here are some key points:

Xcode 16 Overview:
- Xcode 16 introduces a new chapter for development, integrating generative models to enhance tools like code completion. The new engine predicts the code you need, using a model specifically trained for Swift and Apple SDKs. This engine runs locally on your Mac, ensuring privacy and fast results, even offline. For more details, you can check the Platforms State of the Union session.
Swiftassist:
- Swiftassist is a new feature in Xcode 16, acting as a companion for all coding tasks. It can answer coding questions, help with experimenting with new APIs, and assist in prototyping. This feature leverages a powerful model running in the cloud. More information can be found in the Platforms State of the Union session.
Debugging and Testing:
- Xcode 16 includes enhancements for debugging and testing, such as a single view of backtraces, a flame graph for profiling data, and improvements to localization catalogs. These features aim to boost productivity and app quality. For a detailed walkthrough, refer to the Xcode essentials session.
Xcode Cloud:
- Xcode Cloud continues to streamline the process of testing and distributing apps. It integrates seamlessly with Xcode to help developers stay focused and work efficiently. This was highlighted in the Platforms State of the Union session.
Debugging in LLDB:
- The session "Run, Break, Inspect: Explore effective debugging in LLDB" covers advanced debugging techniques in Xcode, including the use of the p command and structured logging. This session is useful for developers looking to enhance their debugging skills. You can start with the Introduction.
