Operations Vs Completion Block Madness

If you are not using Operations, you my friend are missing out big time. Operations are simply put wait for it… AWESOME.

Pass Data Using UIStoryboard Segue Between UIViewControllers

I've been asked a lot of times, how to achieve the most common scenario in iOS, that is to pass data with UIStoryboard segue between 2 UIViewControllers.

Create Custom UICollectionviewCell transition

Create Custom UICollectionviewCell Transition is full of great UI animations, since Apple introduced iOS 7 and its flat design style, every designer went crazy. Especially when they saw the Custom UIViewController transitions in iOS apps, and what can be achieved instead of a normal push, pop and modal transitions.
