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

CustomStringConvertible in Swift

Image
Apple says: " A type with a customized textual representation.  Types that conform to the CustomStringConvertible protocol can provide their own representation to be used when converting an instance to a string. The String(describing:) initializer is the preferred way to convert an instance of any type to a string " CustomStringConvertible is a protocol and it's used print informative data of your object. Ok So let's start class Employee{ let name: String let surname: String init(name: String, surname: String) { self.name = name self.surname = surname } } let emp = Employee(name: "Pawan", surname: "Manjani") print(emp) So here if you print your class instance then it will print like below <YourProjectName.Employee: 0x60000152b240> So what we see here is not very informative, So if you want to print a readable data over here so here CustomStringConvertible  will help yo...

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...
