I'm having weird trouble using a C enumeration imported via bridging header 
from swift. I can define an instance variable and initialize it using the enum, 
but I can't compare the enum:

Camera.swift:60:18: Cannot invoke '==' with an argument list of type '(@lvalue 
McpSweepState, McpSweepState)'

The code is here:

class
MyClass
{
    func
    getCameraState()
        -> McpCameraState
    {
        if mSweepState == MCP_SWEEP_UNKNOWN             //  <---- error here
        {
            return MCP_STATE_SWEEP_IN_PROGRESS;

        }
        else
        {

            return MCP_STATE_READY;
        }

    }
    
    var mSweepState: McpSweepState    = MCP_SWEEP_UNKNOWN; // <--- no error
}

------------------------------------------------------------
Imported via bridging header:

enum McpSweepState
{
    MCP_SWEEP_UNKNOWN          = 0,
    MCP_SWEEP_EMPTY            = 1,
    MCP_SWEEP_ROTATING         = 2,
    MCP_SWEEP_PROCESSING       = 3,
    MCP_SWEEP_COMPLETE         = 4,
    MCP_SWEEP_CANCELED         = 5,
    MCP_SWEEP_ABORTED_PHYSICAL = 6,
    MCP_SWEEP_ABORTED_DATA     = 7,
    MCP_SWEEP_ERROR            = 8,
};
typedef enum McpSweepState McpSweepState;

enum McpCameraState
{
    MCP_STATE_UNKNOWN           = 0,
    MCP_STATE_READY             = 1,
    MCP_STATE_SWEEP_IN_PROGRESS = 2,
    MCP_STATE_BLOCKED           = 3,
};
typedef enum McpCameraState McpCameraState;
