Serious iOS Issue with GS1-128 Barcodes

Barcodes with iOSAs you might now I have an dual interest in product barcodes. First, there is my book treating all kinds of barcode symbologies supported by iOS. Second, there is ProductLayer where we are building a crowd-sourced product database via the social network.

At first I thought that the problem would only exist for really low quality bar codes (rdar://19438067) but now I found a perfectly good looking specimen that has the same issue: iOS does not recognize it.

Filed as rdar://22048146 and on Open Radar. I am hoping that Apple can fix this issue before iOS 9 is done.

Radar: Xcode framework for wrong platform

It took me almost an entire day to figure out that the following issue is caused by some indeterministic behavior of Xcode. As a developer, you expect to see the same results if you use the same parameters (i.e. “deterministic”), but this is a situation that sometimes succeeds, sometimes doesn’t.

In DTFoundation I have two targets that produce a DTFoundation.framework, for iOS and OS X respectively. Now the problems seems to be that since I set both to define a module “DTFoundation”, Xcode randomly gets confused during building an iOS app and sometimes might try to build the OS X framework for iOS.

This was filed as rdar://22008701 and on Open Radar. From the looks of things Rob Rix has filed bug report rdar://20490378 that appears to be describing the same issue. If you disable implicit dependency finding in the scheme, the problem also goes away.
