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!

for Swift 3:

extension ZBarSymbolSet: Sequence {
    public func makeIterator() -> NSFastEnumerationIterator {
        return NSFastEnumerationIterator(self)
    }
}

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
        // ADD: get the decode results
        let results: NSFastEnumeration = info[ZBarReaderControllerResults] as! NSFastEnumeration

        var symbolFound : ZBarSymbol?

        for symbol in results as! ZBarSymbolSet {
            symbolFound = symbol as? ZBarSymbol
            break
        }
        let resultString = symbolFound!.data
        print(resultString)
    }

Here is the solution

following link helped me https://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) } 
}
