-Replace `release` with `debug` in library file names for a Debug mode config respectively. You can assign such `.xcconfig` file to your target in Xcode: add it to your project, navigate to the project's Info tab, and select it in the build configuration for Debug and Release modes.
+For a Debug build configuration, replace `release` with `debug` in the library file names. Remember to link against the ExecuTorch runtime (`libexecutorch`) in Debug mode even if other components are built for Release to preserve logs if needed.

+You can assign such a config file to your target in Xcode:
+
+1.	Add the `.xcconfig` file to your project.
+2.	Navigate to the project’s Info tab.
+3.	Select the configuration file in the build configurations for Release (or Debug) mode.
