Cannot find method `(nullable MBProgressHUD *)HUDForView:(UIView *)view` in Swift 3

Hi,

I found this Objective C API in MBProgressHUD.h but when I try to use it from Swift, the compiler throws an error. Any suggestions how I can access it from Swift or possible reasons why the API is not accessible from Swift.

Thanks

In Swift 3 this is next function: /**

• Finds the top-most HUD subview and returns it.
• @param view The view that is going to be searched.
• @return A reference to the last HUD subview discovered. / public /not inherited*/ init?(for view: UIView)

Thanks. I was just curious to know how the objective C header is bridged to Swift as it seems almost impossible for me to guess how it converts the above static function in Objective C to an optional initializer.

Regards.

the function is not exported to swift (4.2): + (nullable MBProgressHUD *)HUDForView:(UIView *)view;

If renamed to i.e. "findHUDForView" it is accessible from swift by: MBProgressHUD.find(for: myViewParam)

Instead of renaming you can add the following (new line!) after the definition in the header file:

+ (nullable MBProgressHUD *)HUDForView:(UIView *)view NS_SWIFT_NAME(find(for:));

With this "annotation" the method can be called from swift 4.2 with: MBProgressHUD.find(for: myViewParam)

As I said: HUDForView is not a constructor but a lookup method, that searches a HUD in all subviews. Please think about fixing this, as we still need this method.
