  2. Introduction SwiftUI is a latest innovative, Swift syntax is very simple to read and developer friendly to write, It is used to implement user interface across all apple platforms.

  4. 01 Declarative vs Imperative Programming

  5. Declarative vs Imperative Programming The core difference between the term imperative and declarative. Now back to UI programming. Imperative UI programming requires developers to write detailed instructions to layout the UI and control its states. Conversely, declarative UI programming lets developers describe how the UI looks like and what you want to do when a state changes. Image Source

  6. 02 No more Interface Builder and Auto Layout

  7. No more Interface Builder and Auto Layout In Xcode eleven, you'll choose from SwiftUI and Storyboard to make interface. If you have got designed associate app before, you will use Interface Builder to layout UI on storyboard. With SwiftUI, Interface Builder and storyboards area unit utterly gone. It's replaced by a code editor and a preview canvas just like the one shown in figure a pair of. You write the code within the code editor. Xcode then renders the interface in real time and show it within the canvas. Image Source

  8. 03 Layout User Interface with Stacks

  9. Layout User Interface with Stacks • Stacks in SwiftUI is like stack views in UIKit. If you are combining horizontal and vertical views in stacks, you'll construct complicated user interfaces for your apps. For UIKit, it's unevitable to use auto layout in order to build interfaces that work all screen sizes. To some beginners, auto layout may be a difficult subject and arduous to be told. The great news is that you simply now not got to use auto layout in SwiftUI. Everything is stacks together with VStack, HStack, and ZStack. Image Source

  14. 05 Understanding State and Binding

  15. Understanding State and Binding In SwiftUI, it comes with many inbuilt options for state management. specifically, it introduces a property wrapper named @State. once you annotate a property with @State, SwiftUI automatically stores it somewhere in your application. what is additional, views that create use of that property automatically hear the worth amendment of the property. once the state changes, SwiftUI can recompute those views and update the application's look.

  16. Understanding State and Binding • In application development every developers need to implement state management. Let's take a example developers developing music player app. So when user click play button now button will change to a stop button. So in your implementation there must be some process to keep track application state and according that you know when to change that button. Image Source

  17. 06 Working with Navigation UI and Navigation Bar Customization

  18. Working with Navigation UI and Navigation Bar Customization • By using stacks, image, and text views, you should be able to create the UI. While I will go through the implementation. • In this image, you can see complete UI sample. Sample navigation interface for our demo projects Image Source
