It seems that Swift does not recognize a typedef in a Objective-C-Header as I get following error:

**Could not find a user-defined conversion from type 'MMDrawerControllerDrawerVisualStateBlock!' to type '(MMDrawerController!, MMDrawerSide, CGFloat) -> Void'**

I use the [MMDrawerController](https://github.com/mutualmobile/MMDrawerController) which is written in Objective-C, my own code though is in Swift.

The typedef looks like this:

```
typedef void (^MMDrawerControllerDrawerVisualStateBlock)(MMDrawerController * drawerController, MMDrawerSide drawerSide, CGFloat percentVisible);

```

Here are more code snippets for clarity:

**AppDelegate.swift**

```
func initDrawerController() {
    drawerController = MMDrawerController(centerViewController: centerController, leftDrawerViewController: leftDrawerController, rightDrawerViewController: rightDrawerController)
    drawerController?.setDrawerVisualStateBlock(MMDrawerVisualState.parallaxVisualStateBlockWithParallaxFactor(2.0))
}

```

**MMDrawerController.h**

```
typedef void (^MMDrawerControllerDrawerVisualStateBlock)(MMDrawerController * drawerController, MMDrawerSide drawerSide, CGFloat percentVisible);

@interface MMDrawerController : UIViewController
-(void)setDrawerVisualStateBlock:(void(^)(MMDrawerController * drawerController, MMDrawerSide drawerSide, CGFloat percentVisible))drawerVisualStateBlock;
@end

```

**MMDrawerVisualState.h**

```
@interface MMDrawerVisualState : NSObject
+(MMDrawerControllerDrawerVisualStateBlock)parallaxVisualStateBlockWithParallaxFactor:(CGFloat)parallaxFactor;
@end

```

**Module-Bridging-Header.h**

```
#import "MMDrawerController.h"
#import "MMDrawerVisualState.h"

```

When building this, I get an error in my AppDelegate for the Expression with `setDrawerVisualStateBlock`, although there is a typedef in the `MMDrawerController.h`:

Is this a bug (because on Objective-C, it works fine)? Or is there anyone who knows/has an idea how to deal with it?
Help is much appreciated, thanks!
