1. What’s Great: IOS8 & Xcode6 2014/10/02 @mattak
2. AGENDA + Touch ID + Swift 1.0 + Metal & SceneKit
3. 1. Touch ID
4. IF OS >= iOS8 API is PUBLIC!
5. USAGE 1. import LocalAuthentication.framework 2. write a few code.
6. CODE context.evaluatePolicy( LAPolicy.DeviceOwnerAuthenticationWithBiometrics, localizedReason:"ࢦ໲ೝূγϚε", reply: { success, error in if success { println(“ೝূͰ͖ͨΑ”) } else { println(“ೝূࣦഊͨ͠Α”) } })
7. VIEW
8. 2. Swift 1.0
9. Swift … + Modern + Safety + Fast + Powerful + Interactive is + Playground has
10. Modern Type inference. let a = “hoge” // จࣈྻͱܕΛਪ࿦ Nil coalescing operator // var a = (b != nil) ? b! : c var a = b ?? c switch / enum / func / closure …
11. Safety Immutable or Mutable is very clear. let a = “hoge” // มߋෆՄೳ var b = “hoge” // มߋՄೳ Nil safe var a: String? = “hoge” // ? Ͱએݴ͢ΔͱnilΛ୅ೖՄೳ str?.length // ? ͕ม਺໊ͷޙʹ͋Δͱnilͷ࣌ɺ࣮ߦ͠ͳ͍
12. Fast http://cloudfront8.ia.net/wp-content/uploads/2012/05/writer-iphone-iPad-Mac.png Swift LLVM Compiler
13. Powerful Generics enum Operator<T> { case None case Some(T) } let a : UInt32 = 12 var binaryInteger = 0b10001_01100 Low-level primitives
14. Playground Value Result
15. 3. Metal & SceneKit
16. Metal? + is high-performance GPU computation framework + works on A7(A8) GPU + replace OpenGL
17. What’s Great? + x10 draw calls (OpenGL => Metal) + Designed for A7 Architecture + very low overhead + Efficient Multithreading + Unity5 will be supported

21. SceneKit? + 3D Scene renderer + for casual game + Physics engine + 3D Particle system + Scripted actions
22. What’s Great? + 3D particle system! + write game with Swift. + Xcode support 3D assets

24. A lot of fun!
