iOS emulation never gets past the splash screen

Hasn’t been a problem in the past, but I’ve been trying to get the app working in the emulator and it gets stuck at the splash screen. App seems to work OK on the device.
The app has an initialize function which ought to hide the splash screen—that happens after the platform ready() event fires.
Have been watching through Xcode logging and I’m not seeing any errors, here.
Could it be related to something which requires the production certificates but doesn’t want to work with dev certificates?

OK—solving my own problem here. Apparently I was looking in the wrong spot. At the very top was a message about address in use. Cordova wants to listen on port 8080 and I already had something running locally on that port. Closed that down and it started immediately working.
