If you want to import gif file from Xcode's simulator camera library, make sure you download the .gif file from simulator's safari or save gif from your application to camera library. If we import .gif file to xcode simulator by simply dragging file from system, it will automatically get converted into .png file.

    let savingPath : AnyObject = NSSearchPathForDirectoriesInDomains(.DocumentDirectory,.UserDomainMask,true)[0]

    var library:ALAssetsLibrary? = ALAssetsLibrary()
    var referenceURL : NSURL = info[UIImagePickerControllerReferenceURL] as! NSURL
    library!.assetForURL(referenceURL, resultBlock: { (asset : ALAsset!) -> Void in
        var assetRep : ALAssetRepresentation = asset.defaultRepresentation()
        let sizeOfRawDataInBytes: Int = Int(assetRep.size())
        var rawData: NSMutableData = NSMutableData(length: sizeOfRawDataInBytes)!
        var bufferPtr: UnsafeMutablePointer<Void> = rawData.mutableBytes
        var bufferPtr8: UnsafeMutablePointer<UInt8> = UnsafeMutablePointer<UInt8>(bufferPtr)

        var error: NSError? = nil
        var buffered =  assetRep.getBytes(bufferPtr8, fromOffset: 0, length: sizeOfRawDataInBytes, error: &error)
        let newData: NSData = NSData(bytesNoCopy: bufferPtr8, length: buffered, freeWhenDone: false)

        newData.writeToFile( savingPath , atomically: true)
