Using zbar sdk and converting to swift 3, will it work?

Question

I'm planning to convert the code to Swift 3 in xCode 8, but I'm hesitant to do so, because of the frameworks I use, especially ZBar SDK (I'm getting it with CocoaPods). Does anyone know, if the conversion can make this (or other) framework unusable?

The only changes should be the protocol part, you may refer to this post.

How to import Zbar Framework in Swift Project

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)
}
