Frame vs bounds in Swift



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

Property wrapper in Swift

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  👨‍💻

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" ) More formatter Sunday , Apr 07 , 2019 --> EEEE , MMM d , yyyy 07 / 04 / 2019 -
