DEFAULT_OPTIONS =

Controls the behavior of Xcrun#run_command_in_context.

You can override these values if they do not work in your environment.

For cucumber users, the best place to override would be in your features/support/env.rb.

For example:

RunLoop::Xcrun::DEFAULT_OPTIONS = 60

{
  :timeout => 30,
  :log_cmd => false
}
