How can I draw gantt chart Using UIcollectionviewController?
I'm not a UICollectionView expert, so I can't help you directly. I can, however, move your thread over to App Frameworks > Cocoa Touch, where you're more likely to find UIKit gurus.

let myEmail = "eskimo" + "1@apple.com"Yes, you can definitely use UICollectionView (and related UICollectionViewController, and UICollectionViewLayout classes) to draw a chart like that. I'd recommend reading the Collection View Programming Guide for iOS to get a good understanding of how the pieces of a collection view fit together. The key design of a collection view is that the layout is separated from the view itself. There are a number of components that go into a collection view, but once you understand all the pieces it's relatively straightforward, and extremely powerful.
At a high level you'd be looking to create a custom layout subclass of UICollectionViewLayout that knew how to layout the various elements of a Gantt chart, and likely a custom UICollectionViewController subclass that would then manage the connection to your Gantt data.
There's an example of a custom collection view controller and layout here: Collection View Transition.
