How to import Zbar Framework in Swift Project

I have a project and currently trying to convert to Swift project but I couldn't figure out how to present a Zbar barcode reader that scans from the camera feed.
On my current project I called like this

- (IBAction)scanButton:(id)sender {

// ADD: present a barcode reader that scans from the camera feed
ZBarReaderViewController *reader = [ZBarReaderViewController new];
reader.readerDelegate = self;
reader.supportedOrientationsMask = ZBarOrientationMaskAll;

ZBarImageScanner *scanner = reader.scanner;
// TODO: (optional) additional reader configuration here

// EXAMPLE: disable rarely used I2/5 to improve performance
[scanner setSymbology: ZBAR_I25
config: ZBAR_CFG_ENABLE
to: 0];

// present and release the controller
[self presentViewController:reader animated:YES completion:nil];}


Note:
What I did so far



  1. Copy framework into the swift

  2. Added framework path to the Header Search Paths (Targets Section > Build Settings)


    • $(PROJECT_DIR)/Test/ZBarSDK/Headers/ZBarSDK

    • Created Projectname-Bridging-Header.h for Bridging (added all h files from zbar)

    • Added Projectname-Bridging-Header.h to Header Search Paths




After that either if I write "import ZBarSDK" or ZBarReaderDelegate still gives me error!

Answer

Here is the solution

following link helped me http://stackoverflow.com/a/24005242/4059179

But after that I had NSEnumeration Problem so here second problem solution

func imagePickerController(picker: UIImagePickerController,
didFinishPickingMediaWithInfo info: [NSObject : AnyObject]){
var results: NSFastEnumeration = info[ZBarReaderControllerResults] as NSFastEnumeration
} 

Don't forget to extend

extension ZBarSymbolSet: SequenceType { public func generate() -> NSFastGenerator { return NSFastGenerator(self) } 
}
