A few questions:

1) Can you show us the code for the viewcontroller where you call: var facts = Facts() ?

2) If you place a breakpoint after the line "var facts = Facts()" what is the value of the variable facts?

3) If you place a breakpoint on this line: "self.networkOperaton.downloadJSONFromURL({" does the code stop there? The reason I ask this one, is that it's possible the init is being called, but your array just isn't being updated.
