I’ve just added an extension for using Swivel, a feature management system created by the guys over at Zumba. Current version is for Yii 1.1 but I will be porting it over for 2.0 shortly as well.
The extension is available as a composer package, and it’s been kept deliberately light.
Feedback about Swivel itself should go to the Zumba folks, I’ve just created the interaction for Yii and am happy to take feedback and suggestions for any added requests related to that!
Note: While this was extension was created to work for Yii 1.1.x applications, the Swivel library itself requires PHP 5.4+
