What are constants in Swift?
Constants in Swift are values that cannot be changed once they are set. They are declared using the let keyword.
Can you give me an example of how to declare a constant?
Sure! You can declare a constant like this: let pi = 3.14.
What happens if I try to change the value of a constant?
If you try to change the value of a constant, Swift will throw a compile-time error, indicating that the value cannot be modified.
Are there any best practices for using constants in Swift?
Yes! It's best to use constants for values that should remain unchanged throughout your code, improving readability and safety.
