3D dragging in iOS using Core Animation

I recently installed an app on my iPhone called ‘Taasky’

It is a simple task manager to create and manage your to-do lists. Despite the simple functionality it is ordained to do, the UI is beautiful and intuitive and the animations are elegant. One particular animation from the app struck a chord with me. It was a 3D dragging of a view from the top when you pull down your main view to create a task. I have recently started learning Core Animation programming in iOS and wanted to emulate this particular animation of Taasky as best as I can.

The result is my HV3DDrag project on github: https://github.com/hetalv985/HV3DDrag

And here is a video of the animation in action that the HV3DDrag project achieves:

 

Please checkout the project on github and do let me know through your comments if you have any feedback.
