📝Variables are used to store and manage data in Swift.
🔢Data types like strings, integers, floats, and booleans are used to define the type of data that can be stored in variables.
🔀Variables can be assigned different values, even values of different data types.
💡Constants are variables whose values cannot be changed once assigned.
🔣Variables can be assigned values using the assignment operator (=).
What are variables used for in Swift?
—Variables are used to store and manage data in Swift. They allow us to assign values and manipulate data in our code.
What are data types in Swift?
—Data types in Swift define the type of data that can be stored in variables. Common data types include strings, integers, floats, and booleans.
Can variables hold different types of data?
—Yes, variables in Swift can hold values of different data types. They can be assigned different values, even values of different data types.
What is the difference between a variable and a constant?
—A variable in Swift can have its value changed after being assigned, while a constant's value cannot be changed once assigned.
How are values assigned to variables in Swift?
