Shimmering Effect

extension UIView {
  func startShimmering() {
    let light = self.tintColor.cgColor
    let dark = UIColor(white: 0, alpha: 0.3).cgColor

Understanding `UIViewController` Rotation

Problem

To enable the rotation of a single view controller used to display the preview of Images/Videos. It is intuitive to allow user to rotate there device and screen changes accordingly, so it feels pleasant. But to achieve this, we need to enable the (almost) all Supported Device orientations.

Ex: `Portrait`, `LandscapeLeft`, `LandscapeRight`.

CodableResource

Fetch resource using Alamofire with Codable.

This document shows the use of `URLComponenent` to decouple url by use of `swift enums`. By creating a `Result<A>` enum type error handling is done with ease. At the end defining the `Codable` `User` and `Address` structs allows the easy json-parsing.

	let viewFrame = self.view.frame
	let newRect = self.view.convert(self.view.frame, to: self.view.window)

	print("KeyboardFrame: \(keyboardFrame)")
