Tutorial 3 - pg 128 background is all black

On page 126, it says to remove the backgroundColor line and to fill in the drawRect method.

The small HUD is displayed but, the background is completely dark and can not see the table view of the location details controller.

Is anyone else having this problem?

Edit: If I change the background colour inside the convenience constructor I get the result of what it shows on pg.128
hudView.backgroundColor = UIColor(red: 1, green: 1, blue: 1, alpha: 0.0)
