This list curates open-source macOS applications built with Swift, spanning a wide range of categories from productivity to utilities.
For macOS developers, these projects showcase practical Swift implementations and offer high-quality code samples and best practices to help you master core macOS skills such as UI design, performance optimization, and menu bar integration.
