Table of ContentsChapter 1: SwiftUI - A new Beginning Why a New UI framework? SwiftUI Principles Declarative vs Imperative State Management Composition over Inheritance Everything is a View UIs are a function of their state A quick tour of SwiftUI Creating a new app Anatomy of a SwiftUI app Two-way tooling Adding your first button Print “hello” to the console Explain live mode (need to turn on debug mode so you can see console output while in preview) A brief overview of statement management Use code editor and preview pane to update the “hello world” app to allow the user to give their name TextField, Label, (Button) @State to bind the TextField input Bind Label, so it gets updated automatically Run the app in live preview Chapter 2: Getting Started with SwiftUI ○ Building Blocks Views View Modifiers Property Wrappers Simple UI Controls ■ Lists ■ Navigation ○ Composing UIs from simple UI elements Building a list row Making it reusable extracting parts into separate structs / views using ViewBuilders (properties / functions) Chapter 3: SwiftUI Foundation Opaque return types Implicit returns from single-expression functions Function Builders View Builders Multiple Trailing Closures Domain Specific languages Property Wrappers The View Life Cycle Chapter 4: State Management Managing State with Property Wrappers ■ @State ■ @ObservableObject ■ @ObservedObject ■ @StateObject ■ @EnvironmentObject SwiftUI Patterns and State Management Pattern: Drill-Down Navigation Pattern: Input form Pattern: Lookup field Pattern: Local state in a single dialog View Lifecycle See Michael Long’s article Maybe even build some sort of introspector? Build my own debugging utilities Chapter 5: Building Input Forms Building simple forms Build a simple form with a couple of simple input fields. Building advanced forms ■ Look-up fields ■ Drill-down ■ In-place editing (e.g. date picker) ■ Sections ■ Forms and Data Binding / State Management ■ Building a sign-up form ■ Username ■ Password / Repetition ■ Validation ■ Come up with a non-Combine version for the following rules: Do the passwords match? Password strong enough? Username long enough? Username still available? How to handle state? Chapter 6: Functional Reactive Programming and Combine Introduction to Functional Reactive Programming What is it? Why is it so cool / hot? How can it help to make your apps better and more error-free Core Combine Concepts ■ Publishers ■ Subscribers ■ Operators Combine Visualised Marble Diagrams Show some Combine operators as Marble Diagrams Chapter 7: Combine and SwiftUI ○ Driving UI state ○ Input validation using Combine verify that the passwords match verify username length verify username is still available verify password meets password complexity rules show error messages for the individual error conditions combine all the above into a single state that drives the enabled state of the sign-up button Optimise our code use debounce to throttle the number of calls on our fake backend ensure UI updates happen on the main thread (use receiveOn) Closure Combine makes our code more maintainable. It helps to decouple business logic from our UI This also makes our code more testable Chapter 8: Testing Combine Code Writing tests for asynchronous code Mocking parts of your implementation Some useful helpers Chapter 9: Advanced SwiftUI UIs ○ LazyVGrid / LazyHGrid ○ Outlines Chapter 10: Advanced SwiftUI - Building Reusable UI Components Keep it lean and mean Extracting functionality into sub-views Using ViewBuilders to organise view code within a screen Creating Container Components Making your views customisable Packaging your components using Swift Package Manager Integrating views and view modifiers with the Xcode library Chapter 11: Building a Complete App with SwiftUI and Combine Features of the app Data Model OpenLibrary API Firebase Chapter 12: Displaying a list of books Building a list cell from simple UI views Compose a list view Make your code reusable Chapter 13: Implementing a search screen ○ Implementing a re-usable search bar Designing the UI Data Binding and State Management Making the view re-usable ○ Connecting to the OpenLibrary API Searching book titles Using Combine to improve working with the API Debounce Mapping JSON Data Error handling Automatic retries Chapter 14: Drill-Down Navigation and State Management ○ Implementing a book details / edit screen ○ Drill-down navigation pattern Chapter 15: Persisting Data in Firestore What is Firebase? What is Firestore? NoSQL ■ Real-time Sync Mapping our data model to Firestore Reading and writing data from / to Firestore Implementing Combine Publishers for Firestore Chapter 16: App Store Hero Animation Magic Move SwiftUI Magic Move Animations Explain how they work Transition the current list view to make use of animations Distribute your code Appendix A: An Overview of all SwiftUI ViewsReviewsAuthor InformationPeter Friese is a software engineer, author, speaker, and musician with a passion for helping developers build great apps.
