What is Swift Assist?

Swift Assist is a new feature introduced by Apple to enhance the coding experience in Xcode. It acts as a companion for all your coding tasks, capable of answering coding questions and assisting with tasks like experimenting with new APIs. Swift Assist leverages a powerful model that runs in the cloud to help developers transform ideas into code using natural language. It is particularly useful for prototyping, as it can quickly visualize ideas and create personalized code based on project details, including symbols and their relationships.

Swift Assist is designed with privacy and security in mind; your code is never stored on the server and is only used for processing your requests. Apple ensures that the code is not used for training machine learning models. This tool is part of Xcode 16 and aims to turbocharge the way developers work by providing predictive completions and other intelligent features.
