Trying to set up TC for the first time. I installed 9.1.1 on our Mac mini that we use as a build box. Xcode 7 beta 6 is installed and works fine - we are also testing Xcode Server and it works, but has issues. I created a new project / build config and set it up according to the documentation. But it won't build b/c it says there are no compatible agents and I have no idea how to rectify this. I tried leaving the "Path to Xcode" field blank, and also putting in the correct path. I also verified that xcode-select is pointing to the right place. Help?
