************************
Parasolid Bridge and iOS
************************

On iOS, HOOPS Exchange is provided as a static library.
The same occurs for the :doc:`Parasolid Bridge </guide/parasolid/overview>` which is available under a library file called `libhepb.a`.
If the Parasolid Bridge is not used on iOS, its functions are replaced with placeholders which now have to be disabled using a specific macro definition.
