Enum example TagColor step 2

example.swift

var myTag = TagColor.Red
var yourTag = TagColor.Green
var aColor: TagColor

aColor = .Blue

TagColor.Blue.toString()

print(myTag.toHex())
print(myTag.toUIColor())
print(myTag.toString())

// A function that takes an enum value
func makeTag(color: TagColor) {
    print("makes a tag of color:\(color.toString())")
}

makeTag(TagColor.Purple)

// If the type is an enum you can shorten to a dot and the keyword name
makeTag(.Green)
