Types in Swift fall into one of two categories: first, “value types”, where each instance keeps a unique copy of its data, usually defined as a struct, enum, or tuple. The second, “reference types”, where instances share a single copy of the data, and the type is usually defined as a class.
Enums are reference types, in that they can have methods and can be executed from command line as well , if they have main method.
C# enum is a value type with a set of related named constants often referred as an enumerator list. The C# enum keyword is used to declare an enumeration. It is a primitive data type, which is user-defined.
An enum type is a special data type that enables for a variable to be a set of predefined constants. The variable must be equal to one of the values that have been predefined for it. Common examples include compass directions (values of NORTH, SOUTH, EAST, and WEST) and the days of the week.
System.Enum is a reference type, but any specific enum type is a value type. In the same way, System.ValueType is a reference type, but all types inheriting from it (other than System.Enum) are value types.
So if you have an enum Foo and you want a nullable property, you need the property type to be Foo?.
If you do myEnum.SomeValue it will be a value type.
suppose we have enum
public enum eCategory
{
health ,
Weapon
}
and a type of eCategory such as :-
eCategory currentcategory;
then currentcategory is of value type
public enum TestReferenceOrValue
{
one, two, three
}
var a = TestReferenceOrValue.one;
var b = a;
b = TestReferenceOrValue.three;
If enums are by reference, changing b affects aConsole.Write(a); → oneConsole.Write(b); → three
