How to import objective c header file in swift project

Question

I am trying to use SDWebImage in a Swift project. I dragged and dropped the SDWebImage library folder into my Swift project and created a bridging header by name listingApp-Bridging-Header.h

Then I imported the header file into my Swift file; like so imported

    import UIImageView+WebCache.h  

  func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{

    let cell : TableViewCell = self.tableView.dequeueReusableCellWithIdentifier("Cell") as! TableViewCell


    let strTitle : NSString = arrDict[indexPath.row].valueForKey("clip_name") as! NSString

      cell.clipName.text = strTitle as String


    cell.videoImage sd_setImageWithURL=NSURL URLWithString,[NSString stringWithFormat:@"%@%@",K_Server_imageurl,[record valueForKey:@"clip_image_path"]];



        return cell

}

It's giving me an error saying add ; before + How would I import the file above into my Swift project correctly?

You need to quote the header file name when importing it in the bridging header. Like this:

#import "UIImageView+WebCache.h";

This is exactly the same syntax as importing header files in objc.

imported header file like #import UIImageView+WebCatche.h in the bridging header also

Then you should be able to use the code in swift without importing anything in swift file.

You need to check the project header search path. And adding the 'umbrella' header would be better than adding headers individually.

You don't need to import anything in your swift file because you have imported them in the bridging header.

It's not enough, you must add this bridge header filename also in your Build Settings - Swift Compiler Code Generation like in this picture:

Don't forget also this (required by SDWebImage):

About the next step:

imageDownloader.downloadImageWithURL(
                        NSURL(string: urlString!),
                        options: SDWebImageDownloaderOptions.UseNSURLCache,
                        progress: nil,
                        completed: { (image, data, error, bool) -> Void in
                            if image != nil {
                                self.bannerImageView.image = image

                            }
                    })
