ZBar is used widely in iOS applications and has an SDK specifically for iphone devices.

ZBar SDK supports the iPhone 3GS and iPhone 4, as they have a camera with auto-focus. The ZBar library does not support the iPhone 3G. At the same time ZBar supports iPad 2 camera, in spite of absense of auto-focus camera.

ZBar is licensed under the GNU LGPL 2.1 to enable development of both open source and commercial projects.

Use this tag for ZBar SDK for iPhone issues. For other platforms there is tag.

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

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?
