Xcode - can't build project

I've published my game as an Xcode project, and I'm trying to build my game in Xcode now, but I keep getting met with an error pretty quickly. I'm making sure to open Xcode via Stencyl, but that doesn't seem to make a difference. What might I be doing wrong?

attaching logs! Thank you!!

Exporting to XCode and build an .ipa is pretty unstable for me, sometimes it works, most of the time doesn't.
I suggest using this method: https://github.com/byrobingames/tapdaq/wiki/iOS:-Publish-ipa-with-Xcode
Some images are missing but you should be able to understand how to do it

Awesome.  This looks great. Thanks so much for your help!!
