I've been debugging this all day.
Here's what I've got:
What I want is to be able to create IPA output from the CI so I can do Continuous Deploy to HockeyApp.
Thus far I've found a few scripts that will take the provisioningprofile file and put it in to
~/Library/MobileDevice/Provisioning Profiles/ which is supposedly all that happens when you "install" one.
However, when building Ad-Hoc|iPhone I'm still met with
/xbuild/Xamarin/iOS/Xamarin.iOS.Common.targets: error : No valid iOS code signing keys found in keychain. You need to request a codesigning certificate from https://developer.apple.com.
So something's not wiring up correctly.
What I can't have is any solution involving me sitting at a Mac w/ a keyboard & monitor connected. I can only interact w/ this VSTS instance via shell scripts.
