8. Reac%ve Programming Observing streams of data, transforming them, and binding the result to some outlet.
9. Streams Text Input, Form Comple1on, Network Requests, Delega1on, No1fica1ons
10. Transforma)ons map it, filter it, sort it, split it, insert it, remove it, prefix it, suffix it, flatten it, replace it
11. Streams + Transforma.ons Demo
12. Bindings !: setText, setHidden, setEnabled, setImage, updateWithJSON, configureWithFoo
13. Demo UIDemoMain(Process.argc, Process.unsafeArgv, nil, "DemoDelegate")
14. Just the beginning! • Common FRP-able pa0erns: • Delegates • Perfect first experiment with FRP! • API clients • User session state managers • Holy Grail: MVVM architecture
15. Framework Op,ons • RxSwi' • Pro: Extremely popular + huge community • Con: Big dependency • Juice is worth the squeeze! • ReacCveCocoa • PromiseKit, BrightFutures, Interstellar • Similar, but different idea + lighterweight
