swift-inspect is a debugging tool which allows you to inspect a live Swift process to gain insight into the runtime interactions of the application.
swift-inspect uses the reflection APIs to introspect the live process. It relies on the swift remote mirror library to remotely reconstruct data types.
swift-inspect can be built using swift-package-manager.
In order to build on Windows, some additional parameters must be passed to the build tool to locate the necessary libraries.
swift build -Xcc -I%SDKROOT%\usr\include\swift\SwiftRemoteMirror -Xlinker %SDKROOT%\usr\lib\swift\windows\x86_64\swiftRemoteMirror.lib
The following inspection operations are available currently.
