Summary:
More and more manufacturers of groceries switch from GTIN (aka UPC) to GS1-128 because next to the product code they can include a best-before date. AVFoundation's metadata object detector has a serious issue with these Code128 barcodes as it does not recognize them. At least not in the range of quality that can be found on product packages.

Steps to Reproduce:
1. Print out the provided barcode
2. Try to scan it with a AVCaptureMetadataOutput set up to detect AVMetadataObjectTypeCode128Code

Expected Results:
- The metadata object should be delivered
- It's content's should be (01)09002233023062(15)150720

In this case 01 is the product GTIN

Actual Results:
- No metadata object is delivered to the delegate
- ... regardless of how you rotate the device around
- the crummy zBar app (free on app store) is able to detect it and opens a google search for 9002233023062

Version:
iOS 9.0 (13A4305g)

Notes:
This is a severe problem because this weakness still exists in iOS 9 making the iPhone effectively unusable for scanning GS1-128 barcodes which are getting more and more prevalent in Europe.

Configuration:
iPhone 6
