Why can't I access objective-c methods even though file is in bridge?

I have a project with a lot of objective-c code. Now I would like to access that code in my swift files. But for some reason I can't access the objective-c methods even though I can initiate an object of that class.

I have a bridge-file with all the .h files added called projectName-Bridge-Header.h

#import "NumberVerificationViewController.h"

And it's path is added in the build-settings (a side question: I can initiate an object from a class even though the bridge path isn't added to the build-settings. Why is that?):

I can initialize an object from the class, but I can't access the method:

var num = NumberVerificationViewController()
num.numberVerificationCallCompleted

The last line gives error that method does not exist.

I'm new to objective-c so it might be something really simple. Still, it's beyond me.

At first glance, it looks like you might be missing the declaration in the .h file to make the method public.

NumberVerificationViewController.h
-(void)numberVerificationCallCompleted:(NSNumber*)responseNumber;

NumberVerificationViewController.m
-(void)numberVerificationCallCompleted:(NSNumber*)responseNumber {
    ...
}
