Code Editor Context Awareness With Active File Access

via “accessibility api-based editor state monitoring”

The first GitHub Copilot, Codeium and ChatGPT Xcode Source Editor Extension

Unique: Uses Accessibility APIs as the primary mechanism for editor state monitoring rather than relying on Xcode source editor extension APIs, enabling richer functionality than native extensions allow. This approach works around Apple's sandboxing limitations by monitoring editor state from outside the extension sandbox.

vs others: Provides richer editor context awareness than Xcode's native source editor extension APIs allow, whereas GitHub Copilot extension is limited to what Xcode's extension APIs expose.
