Swift Var and Let

Defining variables is one of the top priorities in a programming language. Because we keep almost all the values different. There are two easiest ways to do this in Swift let and var you can easily define variables with variables.

The difference between these two types of variables is that if you ask, what is the difference is actually quite simple. This is not the case in the variable type where you can later change the value of the variables you define with the type of var variable, that is, you can increment or decrement the value or assign a new value. The Let variable type is similar to the static type in C #.

Now you can think of all the variables in your mind at that time. Let variable type has positive sides compared to var type. Let variable type is less in size, it takes less space in RAM and allows our applications to work more efficiently.
