## Description

swiftui-introspect is a native view introspection library that provides a bridge between declarative interfaces and their underlying platform components. It functions as a reference manager and component wrapper, allowing for the retrieval and manipulation of the native platform views that power a user interface.

The project enables the access of underlying UIKit and AppKit view instances to apply customizations and styling not available through standard APIs. It allows for the definition of custom types to gain access to native platform views that are not supported by default, effectively extending the framework to include native views not yet officially wrapped.

The library incorporates a system for storing weak references to native platform views to prevent memory leaks and retain cycles. This is supported by a suite of utilities for platform integration and native view memory management.
