Stored and Computed Properties in Swift




1, Stored Properties

The simplest form of a variable declaration provides only a type. Stored variables must be initialized before use. As such, an initial value can be provided at the declaration site.

  "A stored property is one that saves a value for use later."

 
var count : Int



2, Computed Properties

A computed variable behaves syntactically like a variable, but does not actually require storage.  compute the value by providing a getter and an optional setter to retrieve and set other properties and values indirectly rather than storing values directly.
get { } : When retrieving the value of a property this block of code will get executed.
set { } : When setting the value of a property this part of code will get executed.
"A computed property is one that runs some code in order to calculate the value."

 
var variableName: dataType {
    get {
        //code to execute
        return someValue
    }
    set(newValue) {
        //code to execute
    }
}

Frame vs bounds in Swift

Image
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  👨‍💻

DateFomatter in Swift

Image
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 -

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  👨‍💻
