Can't drag insert button into Files Owner


In Figure 28.12 Selecting an action,

I am confused as to why Xcode is not allowing me to drag my insert button into the ‘File Owner’ tab.
Perhaps it has already been copied there automatically?

Using Xcode 4.2.6


All good, just discovered the solution was to Control-drag.


Just a a side=note for people using a Windows VNC connection, you can right-click and connect objects because the Control key doesn’t work.



The same problem! I’m using XCode 5 and 6. Control button is pressed.
In XCode 6: dragging on File’s Owner is unavailable.
In XCode 5: after dragging i get menu without createNewItem or any similar point.

Please help!
