# SPI import ignored (SPIImportIgnored)

## Overview

Overview A module was imported with @_spi but the import will not expose any SPI symbols because the module was loaded from its public interface rather than from a binary module or private interface. SPI symbols are only available when a module is loaded from a .swiftmodule binary or a .private.swiftinterface file. When only the public .swiftinterface is available, the @_spi attribute on the import has no effect. To resolve this warning, ensure that either the binary .swiftmodule or the .private.swiftinterface for the imported module is available on the search path, or remove the @_spi attribute from the import if SPI access is not needed.
