Basic iOS Development

In this part, iOS Development is started by the learners starting with basic things that are needed to build an app in Apple.  Swift language is a powerful and intuitive programming language for all Apple platforms.In iOS each developer can create views using storyboards, xibs or programmatically. Independent from the approach, we need to understand when the view is created, loaded, appeared, or destroyed so we can improve our user interface. Therefore, understanding all lifecycle methods not only helps us in code, but also enables us to be more creative and implement an advanced user interface. 

Auto Layout defines a user interface using a series of constraints. It is a property developers can add to frames and components. UIStack View, XIB UIViewController, XIB UIView and UIView Programmatically is serially learnt before Auto Layout programmatically. Auto Layout constraint allows developers to create views that dynamically adjust to different size classes and positions. The constraints enable developers so that their views adjust to any size changes without having to manually update frames or positions.
