McKinley

McKinley is a Mac application designed to streamline the creation of SF Symbols—Apple's vector symbol format used in native apps. While macOS ships with thousands of built-in symbols, developers can create custom ones for their applications. The typical workflow involves exporting a template from Apple's helper app, editing it in a vector editor, and reimporting with metadata tagging. McKinley simplifies this process by providing a purpose-built interface for symbol design and export. SF Symbols support multiple weights; designers draw three weight variants and the system interpolates the rest.
