Lldb Troubleshooting Guidleines

Hi there,
I have built to a device many times from XCode, and have solved what ever issues have may arisen, however this time I am stumped. I get an lldb error after the application has been built to device.

I am wondering if anyone can give me a basic run down of what they would do in this scenario. Possible problems, etc that they might investigate.

Thanks
Ren

Thanks, I have actually realized, keeping all tabs in XCode open, generally point to the error. I had previously only monitored the console output.
Best.
