How to use swift keywords as an identifier ?

     In Swift, certain words are reserved as keywords and cannot be used as identifiers (variable names, function names, etc.) in your code. However, if you really need to use a reserved keyword as an identifier, you can do so by enclosing the identifier in backticks (`). 

For example, let's say you want to use the keyword "if" as a variable name. Normally, this would result in a compiler error because "if" is a reserved keyword. However, you can use backticks to make it work:

let `if` = 95

Now, the variable is named "if", but it is enclosed in backticks to indicate that it is an identifier and not a keyword.

 It is generally not recommended to use reserved keywords as identifiers, as it can make your code harder to read and understand. Instead, try to come up with a different name that conveys the same meaning.
