What is a Variable?



A variable is a value that can be changed.

To declare a variable simply put var in front of the variable name:

var player: String = "Henrik Larsson"

Change player by setting its value to another of the correct type:

player = "Chris Sutton"

If you declare an object as a variable and do not change it, Xcode will warn prompt you to change the variable to a constant.
