Hello, hoping someone has seen this before. My user account that I was developing on was corrupted, and the new user account that I was provided was slightly different than the previous in spelling. The old provisioning profile no longer worked, so I had to create a new one.
Now when I try and install a build onto the iPhone for testing, I get the following:
-> applicationDidBecomeActive()
Unknown error occured in:
No method at 0x76c870
[Switching to thread 11523]
[Switching to thread 11523]
Immediately after which I get the “GDB: Interrupted” message and the process hangs.
Any clues on where to look for what’s causing this?
Hello! 
Are you able to install the examples from Apple?
Yes, I was able to install and run the Hello World app without any problems. I have no trouble installing the app, it’s just when I try to run it that I get that message and the program halts.
Type following command in GDB (Xcode Debugger) Console:
thread apply all bt
and paste its output here.
Output is as follows:
(gdb) thread apply all bt
