SwiftUI Lecture 6. Property Observers - 'Watching' a var and reating to changes @State - State that is entirely localized inside a View Only used for temporary state like presentations of alerts or editing things or animation Animation - Implicit vs. Explicit Animation - Animating Views (via their ViewModifiers which can implement the Animatable protocol) - Transitions (animating the appearance/..

SwiftUI Lecture 5. SwiftUI Access Control @ViewBuilder - What exactly is that argument to ZStack, ForEach, GeometryReader, etc? Shape - What if I wnat to draw my own View rather than construct it from other Views? Animation - Mobile app UIs look pretty bad without animation. Luckily in SwiftUI, animation (almost) comes for free! ViewModifier - What exactly are functions like foregroundColor, fon..

Grid add rows and columns by replacing HStack with Grid. How Swift deal with memory : the way that Swift cleans up memory is when nobody points to something anymore, it cleans up the memory and frees it up for someone else to use. Memory cycle : if two things are pointing to each other and they’re both in the heap, they’re never gonna be able to go away b/c they’re always gonna have a pointer to..

Lecture 3. Reactive UI + Protocols + Layout Reactive Demo - Make Memorize's View always reflect its Model Varieties of Types View Layout - How do Views get placed on screen? (demo: adapt CardView's font size to the size of the card) SwiftUI is Reactive! Reactive Programming : Model에 변화가 감지되면, 자동으로 View에 나타나도록 해준다. when changes happen in the Model, automatically show up in the View [Model] How to..

Lecture 2. MVVM and the Swift Type System MVVM Design paradigm ‘code organizing’ architectural design paradigm ‘reactive’ user-interfaces concept must be adhered for SwiftUI to work cf) UIKit 프레임워크의 MVC 모델과의 차이? 모델이 뷰에 적용되기까지 data flows model to view (read only) [View] - Reflects the Model - Stateless - Declared : 함수 사용하지않고 그냥 바로 선언해줌 -> time independent (UI 작성 순서 없이 그냥 시간 상관없이 언제든지 작동, 구현) - Re..

Lecture 1. Introduction to SwiftUI SwiftUI를 처음 써보았다. 와.. 이렇게까지 간결할 수 있을까? 엄청나다.. 그냥 대충 휘갈기기만 해도 code clean… ㅋㅋㅋㅋ UIKit 적응한지 얼마나 됐다고 SwiftUI 가 새로 나왔다길래 에라이 귀찮아 그건 또 언제 공부하고 언제 적용해 라고 생각을 했지만, 나온지 얼마 안돼서 아직 상용화가 되기에는 시간이 좀 걸릴 수도 있을지 모르겠으나 정말 쉽고 편해진 것 같다는 생각이 든다. 아직은 매우 낯설긴 하다. SwiftUI 프레임워크에서는 데이터 타입을 거의 class 대신에 struct를 사용한다. AppDelegate / SceneDelegate 가 사라지고 App 프로토콜을 상속받는 struct만이 있을 뿐이다. 기존의..
