The problem has been fixed with the RM 4.17 release. Thank you!
I use RubyMotion 4.16 (Free/Starter License). After I upgraded to Xcode 8.2 today, I am unable to run 'rake' on any RM project.
I get the following error:
ArgumentError: A version may only contain periods and digits.
I tried installing the 10.1 iOS simulator, thinking it might have something to do with RM 4.16 Starter only supporting deployment_target to '10.1', but that didn't help.
Any ideas how to fix this?
