Swift Data Types

     Swift is a strongly typed programming language, which means that every value has a specific type that is known at compile time. Here are some of the data types available in Swift:

1.  Int: Used to represent integer values, such as 42 or -10. 
2. Double: Used to represent floating-point numbers with decimal places, such as 3.14 or -2.5. 
3. Float: Similar to Double, but uses less memory and is less precise.
4.  Bool: Used to represent Boolean values, which can be either true or false. 
5. String: Used to represent a sequence of characters, such as "Hello, world!". 
6. Character: Used to represent a single character, such as "a" or "5". 
7. Array: Used to represent an ordered collection of values of the same type. 
8. Dictionary: Used to represent a collection of key-value pairs, where each key is unique. 
9. Set: Used to represent an unordered collection of unique values of the same type. 
10. Optional: Used to represent a value that may or may not be present. It is denoted by adding a "?" after the type name, such as "Int?". 
11. Any: Used to represent any type of value, including values of custom types. It is less type-safe than other types and should be used with caution. 
12. Tuple: Used to group multiple values of different types together into a single compound value. 

    These are some of the most commonly used data types in Swift, but there are also other types available, such as enums, structs, and classes. Swift is a rich and flexible language that provides a wide range of data types and features to help developers create powerful and efficient applications.
