Objective-C enum not showing up in Swift

Question

I have an enum like this in my objective-c header file:

typedef NS_ENUM(NSInteger, FontSize) {
    VerySmall = 12,
    Small = 14,
    Medium = 16,
    Big = 18
};

Then in my bridge header, I import that header.

from my swift code, when I try to declare "FontSize" as a parameter, the compiler says "Use undeclared font FontSize".

From the developer guide, this should be possible. Is anyone experiencing the same problem?

I had the same problem and resolved it by doing BOTH of the following:

let fontSize:FontSize = VerySmall

I still couldn't see my enums even with NS_ENUM's answer above.

It turns out there were changes in XCode 7.3 where NS_ENUM must be defined outside of the @ interface- @end block.

Start with a clean Swift project , add one file .h

(Accept automatic generation of bridge headers)

Objective-C FontSize.h

typedef NS_ENUM(NSInteger, FontSize) {
    VerySmall = 12,
    Small = 14,
    Medium = 16,
    Big = 18
};

Bridging header

#import "FontSize.h"

Fast implementation

import UIKit
class ViewController: UIViewController {
    let fontSize:FontSize = .VerySmall
}

Built, linked, launched and tested on Xcode 6.4 and 7.0.
