example usage of optional type in swift

	var exampleDictionary = ["foo":1,"bar":2]

	// an optional type means its value can either be some certain type or nothing at all( nil)
	var optionalTypeVariable: Int? = exampleDictionary["someUncertainValue"]

	// calling optionalTypeVariable will either return an integer or a nil, so you should normally check it’s value before actually using it
	if optionalTypeVariable == nil {
	println("The value of optionalTypeVariable is nil")
	} else {
	// calling optionalTypeVariable! will always return an integer, if optionalTypeVariable is in fact nil, then an assertion will be triggered.
