Uncaught exception 'Error codesigning...' in iOS 12

[sankalpanand]

This is my first attempt at testing iOS 12. I'm running into problems with installing the device agent.
iOS - 12.1
Xcode - 10.1
MacOS - Mojave
calabash-cucumber- 0.21.5

I've seen some other codesigning errors related to provisioning profile before and was able to fix them but I can't make any left or right of this exception. Please take a look.

I think you need to update your run-loop version. The current version is 4.x.
