Hello everyone , in this article I will tell you variables and data types for Swift Programming Language.
If you just started programming , this article may not be for you.

Data Types
A. Int
This data type refers to integers.
B. Double
This data type refers to decimal numbers

D. Create multiple variables in single line
Constants
If we want the value of the variable not to be changed later, the variable is defined as ‘let’.
The program will fail if you change it value
Arithmetic operators
We use it for mathematical operations.
Type Conversions
A. Conversion from numeric to numeric
B. Conversion from numeric to textual
C. Conversion from textual to numeric
Tuples :
Tuples are structure that allows us to define more than one value for a variable. It’s like lists.
We come to the end of the article. See you in the next article :)
