So, to declare a variable you use the keyword var followed by blank space and the name of the variable, right?
var someVariable
To give this variable a value you simply add an equals sign and whatever value you like, yes?
var someVariable = "Some Value"
In your case you want to think of greeting("Tom") as if it is already a value that you can assign to the variable.
var result = greeting("Tom")
Now result holds the value returned from the greeting function - understand?
Best of luck with swift/iOS
