The following two lines are equivalent:

	return "Value of foo is \(foo), have a nice day!"
	return "Value of foo is " + foo + "have a nice day!" // Assuming foo is a String already

So in a way you can think of \() as being a means of escaping from the string entirely. I find this more logical than the idea which other languages encourage which is that the variable is somehow embedded inside the string, which is why I actually really like having escape do this in Swift.
