尽管桥接头工作正常，但无法在 Swift 中实例化 Obj C 类

Question

I'm working on pulling a single objective c class into swift. I've got my bridging header working just fine- Xcode is even suggesting the obj c class's name when I type it. I've even managed to reference a delegate protocol in the same header file from my swift file:

BrowserViewController.swift

import UIKit

class BrowserViewController: UIViewController, BrowserTabViewDelegate {

    @IBOutlet weak var browserView: UIView!
    @IBOutlet weak var webViewContainer: UIView!


    override func viewDidLoad() {
        super.viewDidLoad()

        let tabview: BrowserTabView = BrowserTabView();
        // Do any additional setup after loading the view.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

}

Sreen cap of the error: Use of unresolved identifier 'BrowserTabView'. Note that the BrowserTabViewDelegate isn't having any problems with being referenced. It comes from the same obj c header as the BrowserTabView. It suggests the class name, but I can't call init on it.

BrowserTabView.h

#import <UIKit/UIKit.h>
@class BrowserTabView;

@protocol BrowserTabViewDelegate <NSObject>

@optional

-(void)BrowserTabView:(BrowserTabView *)browserTabView didSelectTabAtIndex:(NSUInteger)index;
-(void)BrowserTabView:(BrowserTabView *)browserTabView willRemoveTabAtIndex:(NSUInteger)index;
-(void)BrowserTabView:(BrowserTabView *)browserTabView didRemoveTabAtIndex:(NSUInteger)index;
-(void)BrowserTabView:(BrowserTabView *)browserTabView exchangeTabAtIndex:(NSUInteger)index withTabAtIndex:(NSUInteger)toIndex;
-(BOOL)BrowserTabView:(BrowserTabView *)tabView shouldChangeTitle: (NSString*)title;

@end

@interface BrowserTabView : UIView <UIGestureRecognizerDelegate, UITextFieldDelegate>

@property (nonatomic, strong) UIImage *backgroundImage;
@property (nonatomic, readonly) NSUInteger numberOfTabs;
@property (nonatomic, readonly) NSInteger selectedTabIndex;

@property (nonatomic, readonly) NSMutableArray *reuseQueue;
@property (nonatomic, weak) id<BrowserTabViewDelegate> delegate;

-(id)initwithTabTitles:(NSArray *)titles andDelegate:(id)del;
-(void)addTabWithTitle:(NSString *)title;
-(void)setTabTitlesWithArray:(NSArray *)titles;
-(void)setSelectedTabIndex:(NSInteger)selectedTabIndex animated:(BOOL)animation;
-(void)removeTabAtIndex:(NSInteger)index animated:(BOOL)animated;
- (void)handleLongPress:(UILongPressGestureRecognizer *)gr;
- (void)handlePanGesture:(UIPanGestureRecognizer *)sender;


@end

This is the first time I've been stuck for this long on an issue like this... Most of the existing questions I've seen have to do with bad bridging headers- but I'm pretty certain mine is good. Let me know if I can clean up my question, and thanks in advance for any help.

WI Vision-Bridging-Header.h

//
//  Use this file to import your target's public headers that you would like to expose to Swift.
#import "BrowserTabView.h"
#import "BrowserTab.h"

Such a nice issue. That looks like a bug and we can log it to Swift's community. Changing the delegate following way will help you:

@protocol BrowserTabViewDelegate <NSObject>

@optional

-(void)browserTabView:(BrowserTabView *)browserTabView didSelectTabAtIndex:(NSUInteger)index;
-(void)browserTabView:(BrowserTabView *)browserTabView willRemoveTabAtIndex:(NSUInteger)index;
-(void)browserTabView:(BrowserTabView *)browserTabView didRemoveTabAtIndex:(NSUInteger)index;
-(void)browserTabView:(BrowserTabView *)browserTabView exchangeTabAtIndex:(NSUInteger)index withTabAtIndex:(NSUInteger)toIndex;
-(BOOL)browserTabView:(BrowserTabView *)tabView shouldChangeTitle: (NSString*)title;

@end

There should be browserTabView used instead of BrowserTabView in the methods names.
