Debug an iPhone application Shift Calendar using EKCalender, EKEventstore, EKEvent, UICollectionView,

I have Xcode-Objective C project on Calendar UI. This app loads calendar which is subclass of UICollectionView. This also loads data from EKEventStore, title of an event which is a shift(work). What I want you to do. 1). Look at the code in Event Manager class and create dedicated iCloud calendar if available or create a local calendar. Save shifts in it. Two kind of shifts for everyday. Include all other functionality like alter, delete event etc. 2). Make scrolling smoother. Project is only TV based, no upload or download.
