7. “‘I’d like to create an integrated television set that is completely easy to use,’ he told me. [...] ‘It will have the simplest user interface you could imagine. I finally cracked it.’”

12. The future of TV is iOS
13. Accelerate AudioToolbox AudioUnit AVFoundation AVKit CFNetwork CloudKit CoreBluetooth CoreData CoreFoundation CoreGraphics

18. MULTIPEERCONNE CTIVITY
19. PORTING EXISTING APPS
20. COCOAPODS ▸ Supports tvOS since 0.39.0 ▸ New platform: platform :tvos, '9.0'
21. PODS SUPPORTING TVOS ["AFNetworking","Alamofire","CocoaLumberjack","SwiftyJSON","Charts", "Quick","Bolts","SnapKit","RxBlocking","RxCocoa","RxSwift","Nimble", "Argo","UICKeyChainStore","AsyncSwift","DTFoundation","Sync", "KeychainAccess","upnpx","AlamofireImage"] If you are adventurous ! https://github.com/orta/cocoapods-expert-difficulty
22. SPRITEKIT EXAMPLE
23. DOOM CLASSIC ▸ UIKit changes (UIAlertView, UISlider) ▸ AudioSession isn't available ▸ Newer C++ compiler
24. NIBS ! If you feel like copy-pasting stuff between NIBs ! https://github.com/neonichu/DOOM-IOS2/tree/tvos
25. STORAGE LIMITATIONS ▸ app is limited to 200 MB ▸ 500 KB of persistent storage (NSUserDefaults) ▸ Use iCloud ▸ Use On-Demand resources
26. NO DIRECT MANIPULATION
27. FOCUS ENGINE UIButton().canBecomeFocused() // == true or false UIButton().focused // == true or false UIScreen.mainScreen().focusedView // nil or the view in focus
28. REACTING TO FOCUS CHANGES func didUpdateFocusInContext(context: UIFocusUpdateContext, withAnimationCoordinator coordinator: UIFocusAnimationCoordinator) context.nextFocusedView // the view which gets the focus context.previouslyFocusedView // the view which had the focus func addCoordinatedAnimations(_ animations: (() -> Void)?, completion completion: (() -> Void)?)
29. DEMO
30. SIRI?
31. GAME CONTROLLERS
33. NSNotificationCenter.defaultCenter().addObserverForName(GCControllerDidConnectNotification, object: nil, queue: nil) { (note) in if let controller = note.object as? GCController { if let microPad = controller.microGamepad { microPad.dpad.valueChangedHandler = { (_, x, y) in if let paddle = self.childNodeWithName("Paddle") { paddle.position.y += CGFloat(y) } } } } }
34. GAME CONTROLLERS WORK WITH UIKIT COMPONENTS
35. SIRI REMOTE IS ALSO A GAME CONTROLLER ▸ Profile GCMicroGamepad ▸ Touch surface is a dpad ▸ Two action buttons ▸ Motion (GCMotion) ▸ Seems not to work in the simulator
36. 2.27 If your app’s core functionality doesn’t work with the Siri remote it will be rejected. The app may, however, provide enhanced functionality in connection with a game controller or other peripheral
37. A maximum of two game controllers (plus one remote) can be connected to an Apple TV at any given time.
38. DEMO
39. TVML
40. APP REVIEW !
41. CONCLUSION ▸ tvOS works very well ▸ If you know UIKit, it's easy to start ▸ Think about interaction
