DateFomatter in Swift


Apple Says
  • A formatter that converts between dates and their textual representations.


 In simple word
  • It is a class that can take a Date, and output a String describing that time/date as its format instructions dictate. In other words, it has a few pretty useful built-in formats, and the capability to accept a custom date format string.
  • It helps to convert date to string and also helps from string to date

Example of Date to String

let date : Date = Date()
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "MM/dd/yyyy"
let todaysDate = dateFormatter.string(from: date) //Output will be 05/04/2019


Example of String to Date

let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "MM/dd/yyyy"
let dateObj = dateFormatter.dateFromString("05/04/2019")

1 ,  Frame The  frame  of an  UIView  is the  rectangle , expressed as a location (x,y) and size (width, height) relative to the superview it is contained within. In short ,  a view's location and size using the  parent view's coordinate system 2 ,  Bounds The  bounds  of an  UIView  is the  rectangle , expressed as a location (x,y) and size (width, height) relative to its own coordinate system (0,0).   In short ,  a view's location and size using  its own coordinate system Example: Frame origin = ( 40 , 60 ) width = 80 height = 130 Bounds origin = ( 0 , 0 ) width = 80 height = 130 Thanks for reading, Happy Coding  👨‍💻

Property wrapper in Swift

Image
Property wrapper is the Swift language feature that allows us to define a custom type, that implements behavior from get and set methods, and reuse it everywhere. Declare  @propertyWrapper  keyword before we declare the type that we want to use as property wrapper. It can be  struct ,  class , or  enum . We are required to implement the  wrappedValue  property. Most of the time we declare custom  setter  and  getter  in this property. This property can be a  computed  or  stored  property. Example of @Properywrapper @propertyWrapper struct Capitalized { private(set) var text: String = "" //Declared to store the value var wrappedValue: String { get { return text } set { text = newValue.uppercased() } } } //Now use it struct User{ @Capitalized var userName: String } var user = User() user.userName = "Pawan" print(user.userName) //PAWAN Thanks for reading, Happy Coding  👨‍💻
