Appium using XCode with CircleCI

Hi! I’m trying to setup Appium to work with CircleCI. Unfortunately, our CircleCI build environment is Ubuntu which does not support Xcode. I know there are ways to build the OSX environment through CircleCI, but I can’t seem to understand how to do that while testing a web application as it asks for a project to map to when using Xcode. Is there a way where I can just have Xcode on my build environment, and when my tests are ran and call for Appium, it will open the simulator automatically? I have the Appium server working on CircleCI as well as all of my tests passing locally using Xcode. If anyone needs more information, let me know.
