I just started writing iOS software. I noticed two problems when I tried to execute my first app (chapter 2, hello world). First, the background in the simulator is black when it should be white. Given that the text is black, I don't see anything on the simulator's screen. And second, when I exit simulator, I get a pop up in Xcode that says, "The operation couldn't be completed. (Mach error -308 - (ipc/mig) server died)"
I would gratefully appreciate any insight that might help me understnd what is happening, why it is happening, and of course how to fix it.
Thank you very much,
