Properties. Properties are the variables (to be more precise, member variables) that are declared inside a class but outside the method. Kotlin properties can be declared either as mutable using the “var” keyword or as immutable using the “val” keyword. By default, all properties and functions in Kotlin are public.
Getters and setters are used to protect your data, particularly when creating classes. For each instance variable, a getter method returns its value while a setter method sets or updates its value.
Getters and setters are methods used to declare or obtain the values of variables, usually private ones. They are important because it allows for a central location that is able to handle data prior to declaring it or returning it to the developer.
What is automatic property? Automatic property in C# is a property that has backing field generated by compiler. It saves developers from writing primitive getters and setters that just return value of backing field or assign to it.
@property (getter=yourGetter,setter=yourSetter:) UIButton *but;
