New release: card.io 5.2.2 for iOS

[Bryant Luk]

Hello from card.io!

We have posted version 5.2.2 of card.io for iOS to github.

From the release notes:

--

* You will need to link the `Accelerate` framework to your application.

* Fix issue where an app would hang on card-scanning screen

    ( https://github.com/card-io/card.io-iOS-SDK/issues/153 )

    If an app was displaying the card-scanning screen and was sent to the

    background, when the app was brought back to the foreground, the

    app would possibly hang on certain hardware, mainly iPhone 5S.

* Add Carthage support

    ( https://github.com/card-io/card.io-iOS-source/pull/36

      https://github.com/card-io/card.io-iOS-source/issues/32 )

    Initial support for Carthage. In a Cartfile, you can add

    `github "card-io/card.io-iOS-source"`

    to get Carthage to build a dynamic framework for inclusion in your

    projects.

* Fix warning while running in simulator for 5.2.1

    ( https://github.com/card-io/card.io-iOS-SDK/issues/154 )

    Add the x86_64 and i386 slices to the OpenCV libraries to prevent warnings.

    This was also necessary for clean builds for Carthage.
