xcode6 - What's the proper way to use an Objective-C category within Swift?

Question

I'm trying to import some category methods into my Swift file without any luck.

ios-Bridging-Header.h:

#import "UIColor+Hex.h"

UIColor+Hex.h

#import <UIKit/UIKit.h>

@interface UIColor (Hex)

+ (UIColor *)colorWithHex:(NSUInteger)hexInt;
+ (UIColor *)colorWithHexString:(NSString *)hexString;

@end

I would expect the autocomplete to reveal UIColor(hexInt: NSUInteger) and UIColor(hexString: String)

Actually, your category is transtlated to Swift as follows:

extension UIColor {

    init(hex hexInt: Int) -> UIColor

    init(hexString: String) -> UIColor

}

And because of that, you should be using:

let color = UIColor(hex: 0xffffff) // instead of hexInt:

let color = UIColor(hexString: "ffffff")

Autocompletion may still be buggy in the beta software, though.
