🚧 SwiftUI

Kaynak/Reference: Swiftful Thinking

• ⚙️ Custom Models

Building a custom data type

• ⚙️ ObservableObject Protocol

State management 1

• ⚙️ StateObject and ObservedObject

State management 2

• ⚙️ ViewModel

State management 3, Custom model, Identifiable Protocol, ViewModel, ObservableObject Protocol, @Published, init(){}, @StateObject, @ObservedObject

• ⚙️ EnvironmentObject

State management 4, @EnvironmentObject, .environmentObject()

• ⚙️ AppStorage

@AppStorage()

• ⚙️ Review

We will create a fake user onboarding experience in which a user can sign up, add their name, age, gender, and then log in to our application. In this example we will focus on persisting the data with @AppStorage and making beautiful animations with the .transition modifier.

• ⚙️ Essential Protocols

Identifiable, Equatable, Comparable, and Hashable Protocols

• ⚙️ Core Data

Creating a Core Data model, Adding entities, Setting the properties of these entities

• ⚙️ Core Data 2

Setting up a Core Data stack, Initialize a Persistent Container

• ⚙️ Core Data 3

Inject the managed object context

• ⚙️ Core Data 4

Data manipulations in Core Data

• ⚙️ Core Data 5

Entity relationships, predicates, and delete rules in Core Data

• ⚙️ Background Threads

DispatchQueue, DispatchQueue.main.async { }, .global(qos:), .async, Thread.isMainThread, Thread.current, .background, .userInteractive, .userInitiated
