Found a Solution: To connect an IBOutlet to a property, right click on the element in IB you wish to connect. The connections inspector pops up. Then click on the + sign next to New Referencing outlet and point-drag to the File's Owner. A list of the properties defined in your .h file appears. Click on the property to connect. Same for IBActions. This is not as intuitive as the drag-point to the property in your .h file, but it seems to work.

Same here - please fix this asap. Can't continue working!
