Could be, but I don't think I did anything differently, wiring wise, the second time. At any rate, if the same thing happens again I'll have a better idea of where exactly things went south. Thanks for your assistance.

So something I did in my original app must have screwed this up. The thing is, I have no idea what. I did delete the readFromData method because I intended to use readFromURL instead, but then I ended up deciding to go with readFromData after all and reinstated it. I guess I'll just start over with a new template and see if the problem occurs again.

When I do File > Open, an NSOpenPanel pops up as expected, but after I select a file I just get a dialog telling me that the file could not be opened. In fact, the "readFromData(data, ofType:type, error:outError)" method never seems to execute at all.
