Reactive RubyMotion
summary
Shows a concrete RubyMotion pipeline: button tap → action sheet → image picker → apply filter on a background dispatch queue → upload to an API → insert an image message into a table view, all wired with ReactiveCocoa operators. Demonstrates handling signal of signals with flatten/concat, using subscribe opens the gates to start work, uses takeLast to keep pickers open, and contrasts signals (lazy, repeatable) with promises (eager, single value).
