What does this error message mean?


I’ve been working my way through the 2nd edition of IOS Programming and I’m on Chapter 13.

Because I just got an iPhone 4S, I moved to the latest edition of Xcode and iOS 5 on Lion. Now when I try to build and run the Homepwner app from Ch. 13 I’m getting this error and I’m not sure why:

Couldn’t register Homebrew-Software.Homepwner with the bootstrap server. Error: unknown error code.
This generally means that another instance of this process was already running or is hung in the debugger.(gdb)

Any pointers would be greatly appreciated. I haven’t had any problems prior to switching to iOS 5.


This happens when your device and computer get out of sync while deploying - usually from stopping a build or unplugging your device at a critical time. You can restart Xcode, then perhaps restart your device, and if all else fails, restart your computer as well.
